How to Care for Pincushion Euphorbia

Pincushion euphorbia (Euphorbia heptagona) derives its unique common name from its appearance, which resembles long red needles stuck into a green pincushion. While the plant is resistant to pests and diseases, it is sensitive to excess humidity, which it dislikes. Small yellow flowers (typical of the Euphorbia genus) bloom in summer.

Basic Care Guide

Water

Pincushion euphorbia needs regular watering about once a week, especially during growing seasons. The plants don’t need great amounts of water during temperate environmental conditions, but during hot summer days they need as much water as any other plant. Pincushion euphorbia needs to be watered when the planting medium is dry for 5 cm at the surface. Those grown in indoor environments also need a sufficient amount of moisture during the resting season. To avoid excess moisture in the medium, it is best if small amounts of water are added from below.

What should I do if I water my Pincushion euphorbia too much or too little?

Underwatered Pincushion euphorbia

Pincushion euphorbia and other succulents can endure long periods without water, so it’s unusual to find one of these suffering from underwatering. But, if you somehow forgot about your plant and neglected to water it for a month or more, you’ll probably find your Pincushion euphorbia looking thirsty or with some damage from lack of watering.

It is very easy to identify an underwatered Pincushion euphorbia. Plant look lacklustre and wrinkled. Some may have dried up completely, turned brown and crispy, or dropped off the plant. And of course, the soil will be completely dried out.

If your Pincushion euphorbia is thirsty and underwatered, give it plenty of water as soon as possible. Submerging the pot entirely in water for about 5-10 minutes is a good way to make sure the soil and plant are rehydrated properly. When you feel a sense of moisture on the surface of the soil with your finger, it means the watering is done properly.

Overwatered Pincushion euphorbia

Overwatering is dangerous to Pincushion euphorbia and can be fatal to your plant if you don’t remedy the situation. Too much moisture over time leads to root rot, which prevents the roots from being able to absorb nutrients and water from the soil. Root rot occurs when wet conditions allow fungi and bacteria to flourish in the soil and feed on roots. When you find that it's overwatered, you'd better change the growing conditions, place it somewhere with more air ventilation and adjust water frequency, for example.

The symptoms of overwatering are yellow, swollen, and translucent organs that may even burst open from being over-full with water. If the problem continues without being treated, plant might turn brown or black, and fall off the plant at the slightest touch. Be sure to check the soil to determine if overwatering is the culprit, as some other issues can cause similar symptoms.

It’s a bit difficult (but not impossible) to save an overwatered plant. The key is catching it early before a lot of damage has occurred. If the roots become rotten, it is likely to kill the entire plant. If you suspect you have overwatered your Pincushion euphorbia, the first step is to remove it from its pot and check the roots and soil.

After removing the plant from its pot, gently remove wet soil from around the roots and then rinse them clean in room-temperature water. This helps with removing fungus that might be lurking in the soil and allows you to get a better sense of how healthy the roots are. If your plant has already developed root rot, you will see roots that are dark brown or black, soft, mushy, or slimy.

If the majority of the roots are already affected by root rot, it may not be possible to save the plant. In this case, it is best to remove any healthy stem and try to use these to propagate a new Pincushion euphorbia. If, on the other hand, only a portion of the roots have succumbed to rot and other healthy roots still remain, there is a chance it can be saved.

Use a sterilized cutting tool to remove any unhealthy-looking roots. Once you're left with only the firm, pale roots, it’s a good idea to dip them in a fungicide to kill off any remaining spores. After that you can repot your Pincushion euphorbia in fresh, free-draining potting soil. While this does not always work to save a succulent with root rot, in most cases this plant will be able to make a full recovery and will put out new growth starting in the next growing season.

How often should I water my Pincushion euphorbia?

There’s not a hard-and-fast rule for how often to water Pincushion euphorbia. The best way to determine this is to check the soil and only water when it’s bone dry. You can either stick your finger in the pot or use a moisture meter to check the soil below the surface. When you plant it in a deep pot, you can do this with a stick or chopstick. If it feels even a little bit moist, wait a few days and check it again.

Most people will need to water Pincushion euphorbia about every two weeks in summer and once a month in winter, but there are several factors that can change the frequency. The section below lists some considerations that can help you to determine how often to water.

What should I consider when watering my Pincushion euphorbia?

There are several environmental conditions that will affect how your Pincushion euphorbia needs to be watered, including the container size, soil type, temperature, and humidity.

First off, the container and soil you use will determine how often to water and how much water to use each time. Be sure you use a container with plenty of drainage holes in the bottom so extra water can escape the pot. A small container has less room for soil, meaning it won’t hold as much moisture, while a larger pot will stay wet longer and need to be watered less often. It’s important not to keep your Pincushion euphorbia in an oversized pot as this can easily lead to overwatering. When repotting, move to just one size larger than the current container. A shallow container works better than a deep one, since Pincushion euphorbia has shallow root systems.

Pincushion euphorbia will need to be watered less often in winter and more often in the active growing season in spring and autumn. During the winter, growth slows down considerably and the plant isn’t using much energy or water. There is less water lost to evaporation in cooler winter air, meaning that soil stays wet for much longer than it would in the summer.

This also applies to the general climate around your home. If you live in a humid location with a lot of rain, you will need to water less often than if you live in a dry, arid climate. Remember that conditions at the same geographic location can vary significantly with the season and the use of indoor heating and air conditioning.

Outdoor Planting

If Pincushion euphorbia is planted in the ground, after establishing a root system, it shouldn’t need supplemental water beyond what it receives through precipitation and dew. But if there is a long dry period, you may want to water occasionally. In other areas where Pincushion euphorbia can only be grown in a container, this plant can be moved outside in the spring and summer when the temperature is proper and then brought back inside when temperatures start to drop. A potted Pincushion euphorbia kept outside usually needs more water than the same plant kept indoors, because there is a lot more sun exposure even on a shaded porch.

How to water Pincushion euphorbia?

The best way to water Pincushion euphorbia is to soak it thoroughly and then allow it to dry out before it gets watered again. Since this plant is somewhat drought tolerant, you can let it get quite dry before watering again. It is always better to give this type of plant too little water over too much.

When you water, make sure the soil gets thoroughly soaked throughout the whole pot. Don’t pour the water in just one spot, but rather try to go around the whole rim of the planter to be sure that it has a chance to get wet on all sides of the plant. The correct amount of water will depend on the size of your container and how much water your soil absorbs. Give your Pincushion euphorbia enough water that it drains out from the drainage holes and then (ideally) leave the drained water in the saucer for about 20-30 minutes to absorb into dry pockets of soil. After that, discard any excess water that’s still in the saucer to avoid the soil getting waterlogged.

Bottom-watering is also an excellent method for Pincushion euphorbia, as you can be sure that the soil gets thoroughly moistened. This process involves placing the pot into a saucer of water and allowing the soil to absorb moisture through the drainage holes. You will know that the soil has absorbed enough water when the top layer is moist. This takes a bit more time than top-watering, but is almost foolproof in getting an even distribution of water throughout the pot.

The original habitat of Pincushion euphorbia is relatively dry with little rain, but when it rains, the soil will be thoroughly moistened. So you can mimic this situation by bottom-watering your plant when the soil is totally dry. Deep soil bathing is better than frequent light watering for Pincushion euphorbia.

Fertilizer

Pincushion euphorbia doesn’t require large amounts of fertilizer for normal growth and development. In fact, very little fertilizer is required. As mentioned earlier, some species can thrive even in very poor soils, as long as those soils are well drained. Fertilizer should only be applied when the plants start showing nutrient deficiency symptoms on lower leaves. When the lower leaves turn yellow, it is time to add half-strength liquid fertilizer to the soil. That will keep the plant well fed for several months.

Often found growing in rock gardens and used in xeriscaping, Pincushion euphorbia adds plenty of interest and texture to the area. It is a slow-growing plant, and this affects its care. Pincushion euphorbia does not require a lot of nutrients to thrive. Knowing when and how to feed your specimen will help ensure you get years of enjoyment from your plant. Fertilizing Pincushion euphorbia adds nutrients to the growing medium. Even though it does store water and nutrients, applying plant food during the growing season helps support healthy growth. Fertilizing can also encourage mature specimens to produce blooms in the growing season.

While all plants benefit from additional nutrients, Pincushion euphorbia only needs a light dose of fertilizer during the growing season. The frequency of fertilization should be 1-2 times a year. It is suggested to fertilize your Pincushion euphorbia in the spring and autumn, but not in winter&summer when it is dormant. Be careful with repotted plants, you will want to reduce the amount of fertilizer. It’s also a good idea to wait a couple of months after repotting before you start applying fertilizer. It’s best to use a liquid plant food formulated for succulents and cacti when you are fertilizing Pincushion euphorbia. Dilute the fertilizer with water to half-strength. You do not want the fertilizer building up in the soil. Apply the fertilizer to the base of the plant and water thoroughly, ensuring any excess moisture drains from the container or seeps into the ground.

It is easier to use liquid plant food when you are fertilizing Pincushion euphorbia, but granules are another option. Follow the directions on the packaging, making sure you dilute liquid fertilizers to half-strength. Whether you are using granules are liquid plant food, always apply it to the soil. Cover the granules with a thin layer of soil and water regardless of the type of plant food you are using.

Over-fertilizing Pincushion euphorbia is a common problem with new and experienced gardeners. The plant has low nutritional needs and it’s easy to apply a little too much fertilizer. Over-fertilizing Pincushion euphorbia can burn the plant’s sensitive roots resulting in its slow decay. Without its root system, the plant cannot absorb nutrients and moisture.

Like most plants, Pincushion euphorbia has a dormancy period and it is when you want to stop the applications of fertilizer. In the summer and winter, the plant ceases growing, and it is when you want to stop applying fertilizer. It’s also a good idea to cease fertilizing for the first couple of months after repotting in the spring.

Why do I need to fertilize my Pincushion euphorbia?

Fertilizing Pincushion euphorbia adds nutrients to the growing medium. Even though it does store water and nutrients, applying plant food during the growing season helps support healthy growth. Fertilizing can also encourage mature specimens to produce blooms in the growing season.

What happens if I fertilize my Pincushion euphorbia too much?

Sunlight

Spurges naturally grow in places that have plenty of sunlight, but some species can tolerate partial shade (e. g., Euphorbia amygdaloides var. robbiae). Full sun provides the best environment for spurges. If they are grown indoors, spurges need at least 6-8 hours of direct sunlight every day for proper development.

How much sunlight does Pincushion euphorbia need to grow?

Pincushion euphorbia should get at least 6 hours of sun per day, and preferably more. An actual minimum number of hours can vary depending on the intensity of sunlight and other environmental factors, but it is unlikely that the Pincushion euphorbia will get too much sunlight. They do fine with up to 14 hours of sun per day.

What type of sunlight does Pincushion euphorbia need?

Pincushion euphorbia needs a lot of bright sunlight. As full-sun plants, they can thrive when given direct light or bright indirect sun. Some types may be able to survive with partial sun, but more sunlight is generally better.

Should I protect Pincushion euphorbia from sun exposure?

Pincushion euphorbia usually grows in some of the hottest, sunniest places in the world and is well adapted to that kind of environment, so it does not need to be protected from the sun. However, you should be careful about making a sudden move into a very sunny location if your Pincushion euphorbia is not used to it. Plants need time to adapt to different conditions, so start by moving this plant into the sun for a couple of hours at a time each day, then gradually lengthen the amount of sun exposure. Once adapted, most types of Pincushion euphorbia will be fine in full sun and don't need protection.

What will happen if Pincushion euphorbia doesn't get enough sunlight?

Without enough sunlight, Pincushion euphorbia will fail to thrive and grow. Common symptoms of inadequate sunlight include pale coloring, wilting leaves, and leaf drop. Pincushion euphorbia may also exhibit etiolation (also called legginess). This condition occurs as the plant attempts to stretch toward the light source, leading to a sparse appearance and weak stems.

What will happen if Pincushion euphorbia gets too much sunlight?

Pincushion euphorbia may develop shades of red, pink, or orange as a means of protection from excess sunlight, so many people like to cause mild sun stress to these plants during the summer. This is not harmful, and they will revert to their normal coloring when light levels decrease from autumn to spring.

If moved too quickly into direct sun, Pincushion euphorbia can suffer from sunburn. This looks like white or brown spots on the uppermost leaves that have been exposed to the most sun. A sunburned plant should be moved to a shadier location and watered if needed. Sun-damaged leaves can be removed, and should be replaced by new growth over time.

Does Pincushion euphorbia need special care about sunlight during its different growth stages?

As with most plants, younger Pincushion euphorbia will be more sensitive to strong sunlight and heat than a mature specimen. They should also be protected from direct sun immediately after being transplanted, either by a shade or by keeping the container in a shadier location until the plant is established and putting out new growth.

Are there any cautions or tips for sunlight and Pincushion euphorbia?

It is best to water Pincushion euphorbia in the morning, particularly during the summer months. If water sits on the leaves or in the crown of the plant, it can burn the plant when the water heats up. It’s also best not to water in the evening, since cooler overnight temperatures slow evaporation and fungi or bacteria can develop in the moist conditions.

Pincushion euphorbia grown in pots should be rotated occasionally to keep them growing symmetrically. Plants will normally grow toward the light source, so they can develop much more quickly on one side than the other if they are not rotated.

If Pincushion euphorbia is allowed to get dusty, it will not be able to access sunlight to create energy. The dust acts as a barrier, so the plant may show signs of inadequate light even if it’s in a sunny location. Keep the leaves and stems clean by wiping them periodically with a damp cloth to avoid this issue.

Pruning

In early spring, if there are any damaged stems, they need to be removed to keep the plants healthy and to optimize their nutrient management. It is advised to cut back a certain number of stems after blooming in order to stimulate consistent flowering and growth of new foliage. When cutting a stem, cut at the stem’s base. It is very important to use gloves while handling and pruning pincushion euphorbia, because their tissues contain milky-white latex sap which is poisonous and can irritate the skin.

Advanced Care Guide

Temperature

Genus Euphorbia is very large and diverse, so its different species can be found in various habitats, but the majority are well-adapted to a temperature range of -29 to 4 ℃. Many spurges, in spite of having succulent leaves, cannot handle long periods without moisture and need to be watered weekly during hot summer days. Some cactus-like species are well adapted to high temperatures and prolonged dry periods, but most species used for landscaping and decorative gardening require more moisture for proper development.

What's the ideal temperature for your Pincushion euphorbia?

It is more suitable to keep the Pincushion euphorbia in a particular range of conditions. Temperatures the same as 75-90℉ (25-32℃) are ideal for it. During the early winter season, the temperature shouldn't go below 75℉(25℃) for Pincushion euphorbia. You can even move it indoors as it will have better protection from the extremes.

Despite that, the Pincushion euphorbia can survive in some extreme temperatures. Sometimes can survive in low temperatures like 50℉ (15℃), but it is not ideal. You should bring it inside if winter conditions are expected outside.

How should I adjust the temperature for my Pincushion euphorbia during different growing phases?

Pincushion euphorbia has different growing phases. In the first stage, the dormant seed grows and transforms into a seedling. The dormant seeds need the appropriate conditions in their surroundings to grow as their seeds need a temperature of 75-90℉ (25-32℃) to germinate. The ideal time to make it grow vigorously is during the summer, as the most suitable temperature is around 85℉(30℃). You can adjust the placement of your Pincushion euphorbia from indoors to sunlight during the hot summer months to receive enough sunlight.

How can I keep my Pincushion euphorbia warm in cold seasons?

It's advisable to bring your Pincushion euphorbia indoors to avoid the harsh winter conditions. People opt to buy different types of grow light to provide enough sunlight for the plant. However, if your home is not extremely dark, it is not essential to buy these lights. Keep your plants where they will get the most sunlight possible. There should be sufficient light to keep the Pincushion euphorbia thriving in winter. If you have several Pincushion euphorbia, then keep them rotating so that they all receive enough sunlight.

Avoid placing your Pincushion euphorbia too close to the window if you live in northern areas with frigid weather. The cold may be extreme to them, due to which they might get damaged.

What happens to my Pincushion euphorbia when the temperature is too high or too low?

Your Pincushion euphorbia can grow better in summers and do better in warm temperatures 90℉(32℃) but you should protect it from temperature extremes during hot climates.

However, during winter, it is better to keep your plant dry. Pincushion euphorbia do well in temperate climates having temperatures between 75-90℉ (25-32℃). However, some gardeners can expose their Pincushion euphorbia to extreme temperatures causing stress in their plants. While high temperatures ranging between 90℉ and 95℉(32-35℃) can help maintain the deep colors for Pincushion euphorbia, you must be careful when trying out such experiment. During the hot summer season extremely high temperatures can burn your Pincushion euphorbia damaging their stem and root system. During the hottest time of the day (when the temperature is extremely high), consider relocating your plant to a shaded place or protect them with a shade cloth.

How should I adjust the temperature for my Pincushion euphorbia in different seasons?

In summers, high temperatures make the growth of Pincushion euphorbia slowed down to survive in too hot a temperature.

As the cooler periods and rainfall begins, the Pincushion euphorbia starts growing. If the place you live in has hot summers and warm winters with more rainfalls, you aren't required to change anything.

However, if you live in a place with cold winters, you should let your Pincushion euphorbia grow more in summer and rest in winter. It is because there is not enough sunlight for Pincushion euphorbia to grow in winter.

You can help your Pincushion euphorbia enter dormancy if you live in a place with cold temperatures by decreasing the temperature to 50℉ to 75℉ (15℃ to 25℃).

How can I keep my Pincushion euphorbia warm without a heating pad?

To withstand freezing temperatures outside, as a solution, you can insulate your Pincushion euphorbia with frost cloths, row covers, tents etc. You can also mulch your Pincushion euphorbia with small rocks. Mulching the Pincushion euphorbia soil will provide warmth to your plants and will not let you over-water the plant.

How can I protect my Pincushion euphorbia from temperature damage?

Pincushion euphorbia is adapted to sunlight and requires sufficient sunlight for healthy growth. You can place it in an outdoor environment without any shade. However, Pincushion euphorbia shouldn't be kept for a long time in the blazing sunlight in the hot summer when it requires to be put under shade so that extreme temperature doesn't damage them. If the winter is extreme in our area, you must keep your Pincushion euphorbia indoors to keep them away from frost.

What are the tips and precautions for keeping my Pincushion euphorbia at the right temperature?

Increase water and fertilizer during the growth of plants in spring and summer. Prevent your plant from receiving too much sunlight. To cool plants, spray water around them when the temperature is exceptionally high but don't put water on their stem.

Soil

Spurges aren’t picky when it comes to soil type. They can grow in a variety of soils. Some species of Euphorbia can even thrive in nutrient-poor soils, requiring only that the soil be well drained. If the soil is full of moisture and is prone to water retention, it will most likely cause root rot.

Propagation

Planting

Harvest

Pincushion euphorbia can be successfully grown from seeds, but the seeds are rarely commercially available because they are difficult to germinate and stay viable only for a short period of time. Pincushion euphorbia is most commonly propagated via cuttings.

It is important to wear gloves while working with pincushion euphorbia cuttings and to clean the pruning shears thoroughly after pruning, so that any unwanted contact with the sap is avoided. Before planting, it is necessary to leave the cuttings to dry for 2-3 days. This will prevent rot from developing and enable proper formation of the callus tissue. It is advised to plant the cuttings in a soilless medium, such as peat moss, because it provides an optimal environmental for proper root development.

Cuttings should be misted regularly, and the pots in which they are planted need to be wrapped in either foil or a plastic bag to preserve moisture. The bag or foil needs to be removed for two hours each day to provide sufficient air and to prevent excess moisture in the medium. If this step is skipped, molds and rots can easily develop and damage the health of the young, sensitive cuttings. When the cuttings develop a root system, they are ready to be transplanted into soil.

If you want to get more plants, you can propagate them as follows.

The active growing season during the spring and summer is the best time to propagate Pincushion euphorbia. During this period, the plants are generating a lot of energy for new growth and should have plenty of stems that can be used for propagation. They can also recover from having cuttings taken during this season than during the slower autumn and winter seasons.

The following are what you need to prepare before propagation can take place.

Sharp scissors or knife
Diluted bleach solution or isopropyl alcohol to clean tools
Pot(s) or nursery tray with drainage holes
Special soil for succulents
Clear plastic bag or a humidity dome for covering cuttings
Rooting hormone (optional but recommended)
Gardening gloves

Steps:

Step 1: Prepare containers by filling them with moistened planting material leaving about half an inch of space from the top of the container.

Step 2: Choose healthy parts for propagation. Cut off healthy stem nodes; the nodes should not be new growth, as this is not easy to succeed. You need to use a clean knife to break or cut off the stem intact at the node location.

Step 3: Leave them for 1-2 weeks, as you need to wait for the cut wounds to dry before taking cuttings. Dip the bottom end of the cutting into rooting powder (if using) according to the directions.

Step 4: Insert the stems into a loose, airy substrate, keeping them tilted, each about one-third of the way into the substrate. Water thoroughly once after planting, after which you need to wait until the soil is dry 2 inches under the surface before watering again.

Step 5: Place it in a location where the cuttings can get light but no direct sunlight, as this can be too intense for cuttings. Water occasionally and do not let the Pincushion euphorbia dry out.

Most species will begin to produce roots in about 3 weeks, After rooting, the plant will gradually grow new leaves, at which time you can start to harden off the Pincushion euphorbia. Hardening off involves gradually exposing the Pincushion euphorbia to more sunlight so that they have time to adjust before being moved permanently outside. Hardening off should usually take about 1 to 2 weeks depending on the outdoor conditions and the type of Pincushion euphorbia. After this period, Pincushion euphorbia can be planted in containers or directly in the ground.

Dig a hole twice as wide as the plant’s root ball before planting. Then, turn the container with pincushion euphorbia upside down and let the plant slowly fall into your hands. Place the plant upright in the hole and slowly fill in around the roots with loose and fertile potting mixture, adjusting the planting depth until it is just right. Water it once. Do not overwater, as standing water is not good for the plant.

Some species of Euphorbia can be cut for fresh flowers or foliage, such as snow-on-the-mountain (Euphorbia marginata), Euphorbia fulgens and Euphorbiaformosana. When harvesting cuttings, remember to wear gloves, as the sap can be irritating to the skin. It can be cut from the base of the stem. Soak the end of the cutting in hot water for 10 seconds to stop the milky sap from oozing. The vase life of for the cutting will be about 5-7 days, and some flower food can extend its life.

When the fruits of Euphorbia plants are ripe, they burst and scatter the seeds over a large surface area. In order to harvest all the seeds, the individual fruits or the entire plant must be wrapped in in nylon, gauze, or similar material before the ripe fruit bursts and releases the seeds.

Transplanting

The ideal time to transplant pincushion euphorbia is during the cooler and less stressful months, such as early spring or autumn. This helps the plant to establish roots in new locations more effectively. Choose a sunny, well-drained spot for pincushion euphorbia to thrive. If the plant becomes too dense, don't hesitate to spread its growth by transplanting.

Seasonal Care Tips

Spring

Summer

Fall

Winter

The plant and similar succulent plants resume growing in the spring after winter dormancy.

Water the plant once or twice a month when the soil begins drying out.

An application of a balanced fertilizer every two weeks helps support healthy growth.

Pruning old growth encourages blooming and branching for a fuller plant.

Spring is also the time to repot the succulent if necessary.

Pay attention to the temperature in the early spring, this plant requires warmth and sunlight to resume growing.

Cutting off a leaf and setting it in a fresh growing medium is an easy way to propagate your plant.

Succulents like this plant are actively growing in the summer.

Keep an eye on soil moisture levels. Do not allow the soil to completely dry out.

Continue fertilizing every couple of weeks with all-purpose plant food.

The plant also requires plenty of sunlight during the day to encourage blooming.

Prune back the old flowers after blooming at the end of the summer.

While your plant is actively growing, you can also remove stems for propagation. Place the stem in fresh soil and lightly water it.

While your plant is starting to enter dormancy towards the end of fall, it's still growing for much of the season.

Continue watering and fertilizing on a regular schedule, but reduce both of these routines as the season winds down and begins reaching dormancy.

Use an all-purpose fertilizer and water the plant when the soil is dry; make sure to err on the side of dry soil rather than soggy soil.

Keep making sure your plant receives enough light during this time, particularly during the morning or evening hours, which will help the plant grow well.

During the cold winter months, the plant usually goes into a dormant state.

Reduce watering your plant in the winter to give it a rest and let it lie dormant. It’s best to keep the plant dry during this season, rather than risk it being soggy.

Make sure it receives an adequate amount of sunlight, typically in the morning or evening, although it’s not as urgent during dormancy.

Since these plants don't survive in freezing outdoor temperatures, keep them in sufficiently warm rooms indoors, away from drafts or cold windows.

For the most part, you can leave these hardy plants to themselves during these colder months.

Common Pests & Diseases

Common issues for Pincushion euphorbia based on 10 million real cases

Scars

Any light-colored markings that appear on stems but which do not enlarge or multiply are simply scars that have healed.

Solutions: Each source of scarring requires a different approach to help your plant recover. Protect the trunk and leaves from physical damage like scrapes. If pests or disease are the cause of scarring, isolate the plant from others to avoid further spread. Some pests can be removed with organic remedies such as a soft cloth and soapy water solution or diluted isopropyl alcohol spray. Stop sunburn by moving your plant away from direct sunlight and making sure it has the water it needs. Frequent leaf or bud loss may be due to insufficient light or nutrients.

Brown spot

This infection can cause brown spots or patches to appear on the plant.

Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.

Underwatering

Leaves may wilt for a variety of reasons.

Solutions: The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with. Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock. In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.

Flower withering

Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.

Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.

Common Problems

Where should pincushion euphorbia be planted the garden?

The best place for pincushion euphorbia in the garden is a sunny spot with loose, well-drained soil.

Are the roots of spurges invasive?

Most spurges don’t have a tendency towards invasiveness. Species that are commonly used in landscaping and decorative gardening are not invasive. There are some exceptions, though. Leafy spurge (E. esula) is considered to be a very invasive species in Northern America. Its roots and rhizomes are very strong and persistent. Leafy spurge presents a great problem, because it competes with other plants wherever it grows, causing reduced diversity of plant species in the area.

Why won’t my pincushion euphorbia blossom?

If pincushion euphorbia has trouble blossoming, it can be due to a lack of sunlight, water, or nutrients. Optimal environmental conditions must be provided, since they are crucial to flowering. If the plants are grown indoors, they should be placed in a spot that gets a lot of sun, as they require at least 6 hours of full light exposure every day.

When does pincushion euphorbia need to be pruned?

Pincushion euphorbia should be pruned after blossoming. This ensures that the growth of new flowers and leaves is constant and well distributed. A little pruning can be also done in early spring in order to remove any wilted or dry leaves.

How to save a dying pincushion euphorbia?

Pincushion euphorbia grows into a very healthy plant with very little care, which makes them an excellent choice for novice gardeners. There are a limited number of problems that pincushion euphorbia encounters, so if anything goes wrong, it will be easy to narrow down the cause. If a pincushion euphorbia seems like it is dying, it is probably due to root rot which is progressing into the upper parts of the plant. This problem can be solved only if the rot is in early stages.

It is recommended to remove any infected parts of the plant. Depending on the severity of infection, that may include removing only a part of the root, the whole root, or even some upper parts of the plant. The unaffected parts can be left to dry for a few days and form callus tissue, and then they can be planted in the medium to develop roots and grow into new plants.

Do the flowers of pincushion euphorbia have an aroma? Is the aroma poisonous?

Pincushion euphorbia flowers do not have a strong scent. The flower’s aroma is very bitter, because like the other parts of the plant, the flowers contain poisonous latex sap. The sap can cause irritation if it comes in contact with the skin or eyes, and it is very harmful if it is ingested.

Winter

The plant and similar succulent plants resume growing in the spring after winter dormancy.

Water the plant once or twice a month when the soil begins drying out.

An application of a balanced fertilizer every two weeks helps support healthy growth.

Pruning old growth encourages blooming and branching for a fuller plant.

Spring is also the time to repot the succulent if necessary.

Pay attention to the temperature in the early spring, this plant requires warmth and sunlight to resume growing.

Cutting off a leaf and setting it in a fresh growing medium is an easy way to propagate your plant.

Succulents like this plant are actively growing in the summer.

Keep an eye on soil moisture levels. Do not allow the soil to completely dry out.

Continue fertilizing every couple of weeks with all-purpose plant food.

The plant also requires plenty of sunlight during the day to encourage blooming.

Prune back the old flowers after blooming at the end of the summer.

While your plant is actively growing, you can also remove stems for propagation. Place the stem in fresh soil and lightly water it.

While your plant is starting to enter dormancy towards the end of fall, it's still growing for much of the season.

Continue watering and fertilizing on a regular schedule, but reduce both of these routines as the season winds down and begins reaching dormancy.

Use an all-purpose fertilizer and water the plant when the soil is dry; make sure to err on the side of dry soil rather than soggy soil.

Keep making sure your plant receives enough light during this time, particularly during the morning or evening hours, which will help the plant grow well.

During the cold winter months, the plant usually goes into a dormant state.

Reduce watering your plant in the winter to give it a rest and let it lie dormant. It’s best to keep the plant dry during this season, rather than risk it being soggy.

Make sure it receives an adequate amount of sunlight, typically in the morning or evening, although it’s not as urgent during dormancy.

Since these plants don't survive in freezing outdoor temperatures, keep them in sufficiently warm rooms indoors, away from drafts or cold windows.

For the most part, you can leave these hardy plants to themselves during these colder months.

Artificial lighting

Indoor plants require adequate lighting for optimal growth. When natural sunlight is insufficient, particularly in winter or in less sunny spaces, artificial lights offer a vital solution, promoting faster, healthier growth.
1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.

Important Symptoms

Insufficient light

Pincushion euphorbia is a beloved choice for indoor gardening, and they require strong light to thrive. However, when placed in rooms with suboptimal lighting, they may develop symptoms of light deficiency.

(Symptom details and solutions)

Small leaves

New leaves may grow smaller in size compared to the previous ones once they have matured.

Leggy or sparse growth

The spaces between leaves or stems of your Pincushion euphorbia may become longer, resulting in a thin and stretched-out appearance. This can make the plant look sparse and weak, and it may easily break or lean due to its own weight.

Faster leaf drop

When plants are exposed to low light conditions, they tend to shed older leaves early to conserve resources. Within a limited time, these resources can be utilized to grow new leaves until the plant's energy reserves are depleted.

Slower or no new growth

Pincushion euphorbia enters a survival mode when light conditions are poor, which leads to a halt in leaf production. As a result, the plant's growth becomes delayed or stops altogether.

Lighter-colored new leaves

Insufficient sunlight can cause leaves to develop irregular color patterns or appear pale. This indicates a lack of chlorophyll and essential nutrients.

Solutions

1. To ensure optimal growth, gradually move plants to a sunnier location each week, until they receive at least 6 hours of direct sunlight daily. Use a south-facing window and keep curtains open during the day for maximum sunlight exposure and nutrient accumulation.2. To provide additional light for your plant, consider using artificial light if it's large or not easily movable. Keep a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights for ample light.

Excessive light

Pincushion euphorbia require strong light to thrive, and some are remarkably resilient to sun exposure, rarely suffering from sunburn.

(Symptom details and solutions)

Chlorosis

Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.

Sunscald

Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.

Leaf Curling

Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.

Wilting

Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.

Leaf Scorching

Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.

Solutions

1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.

Indoor

Requirements

Ideal

Tolerable

Unsuitable

Just like people, each plant has its own preferences. Learn about your plants' temperature needs and create a comforting environment for them to flourish. As you care for your plants, your bond with them will deepen. Trust your intuition as you learn about their temperature needs, celebrating the journey you share. Lovingly monitor the temperature around your plants and adjust their environment as needed. A thermometer can be your ally in this heartfelt endeavor. Be patient and gentle with yourself as you explore your plants' temperature needs. Cherish your successes, learn from challenges, and nurture your garden with love, creating a haven that reflects the warmth of your care.

Essentials

Pincushion euphorbia is a heat-loving plant that gradually stops growing and enters a dormant state during the winter. When the outdoor temperature drops below {Tolerable_growing_temperature_min}, it should be moved indoors for cultivation. Choose a location near a south-facing window to provide as much sunlight as possible. If there is insufficient natural light, supplemental lighting can be used. When the temperature falls below {Suitable_growth_temperature_min}, the plant's growth slows down, and watering should be reduced or stopped to prevent root rot. For Pincushion euphorbia grown outdoors, watering should be completely halted during low temperatures. If feasible, you can set up a temporary greenhouse for insulation or use materials such as plastic film or fabric to wrap the plant during cold temperatures.

Important Symptoms

Low Temperature

Pincushion euphorbia thrives in high temperatures and is not tolerant of low temperatures. It grows best when the temperature is above {Suitable_growth_temperature_min}. During winter, it should be kept above {Tolerable_growing_temperature_min}. When the temperature falls below {Limit_growth_temperature}, the plant may become weak, wilt, and be prone to root rot. In cases of mild frost damage, there may not be any initial symptoms, but after a week, the plant will gradually wither.

Solutions

Trim off the frostbitten areas, paying attention to whether the roots have rotted. If the roots have rotted, they need to be cut off, and the plant can be propagated through cuttings. Immediately move indoors to a warm environment and place the plant near a south-facing window to ensure ample sunlight. If there is insufficient light, you can use supplemental lighting.

High Temperature

During summer, Pincushion euphorbia should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the plant's growth will cease, it will experience water loss, wilting, and becomes more susceptible to sunburn.

Solutions

Remove the sunburned and rotten parts. Shield the plant from afternoon sunlight until it recovers and starts growing again. For plants with root rot, stop watering until new roots begin to emerge.
