Underwatered Pencil cholla Pencil cholla 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 Pencil cholla looking thirsty or with some damage from lack of watering. It is very easy to identify an underwatered Pencil cholla. 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 Pencil cholla 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 Pencil cholla Overwatering is dangerous to Pencil cholla 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 Pencil cholla, 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 Pencil cholla. 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 Pencil cholla 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.

There’s not a hard-and-fast rule for how often to water Pencil cholla. 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 Pencil cholla 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.

There are several environmental conditions that will affect how your Pencil cholla 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 Pencil cholla 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 Pencil cholla has shallow root systems. Pencil cholla 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 Pencil cholla 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 Pencil cholla 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 Pencil cholla 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.

The best way to water Pencil cholla 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 Pencil cholla 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 Pencil cholla, 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 Pencil cholla 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 Pencil cholla.

Pencil cholla 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 Pencil cholla will get too much sunlight. They do fine with up to 14 hours of sun per day.

Pencil cholla 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.

Pencil cholla 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 Pencil cholla 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 Pencil cholla will be fine in full sun and don't need protection.

Without enough sunlight, Pencil cholla will fail to thrive and grow. Common symptoms of inadequate sunlight include pale coloring, wilting leaves, and leaf drop. Pencil cholla 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.

Pencil cholla 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, Pencil cholla 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.

As with most plants, younger Pencil cholla 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.

It is best to water Pencil cholla 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. Pencil cholla 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 Pencil cholla 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.

It is more suitable to keep the Pencil cholla 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 Pencil cholla. You can even move it indoors as it will have better protection from the extremes. Despite that, the Pencil cholla 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.

Pencil cholla 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 Pencil cholla from indoors to sunlight during the hot summer months to receive enough sunlight.

It's advisable to bring your Pencil cholla 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 Pencil cholla thriving in winter. If you have several Pencil cholla, then keep them rotating so that they all receive enough sunlight. Avoid placing your Pencil cholla 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.

Your Pencil cholla 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. Pencil cholla do well in temperate climates having temperatures between 75-90℉ (25-32℃). However, some gardeners can expose their Pencil cholla 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 Pencil cholla, you must be careful when trying out such experiment. During the hot summer season extremely high temperatures can burn your Pencil cholla 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.

In summers, high temperatures make the growth of Pencil cholla slowed down to survive in too hot a temperature. As the cooler periods and rainfall begins, the Pencil cholla 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 Pencil cholla grow more in summer and rest in winter. It is because there is not enough sunlight for Pencil cholla to grow in winter. You can help your Pencil cholla enter dormancy if you live in a place with cold temperatures by decreasing the temperature to 50℉ to 75℉ (15℃ to 25℃).

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

Pencil cholla is adapted to sunlight and requires sufficient sunlight for healthy growth. You can place it in an outdoor environment without any shade. However, Pencil cholla 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 Pencil cholla indoors to keep them away from frost.

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.
