What is the best way to water my Rock purslane?

When watering the Rock purslane, you should aim to use filtered water that is at room temperature. Filtered water is better for this plant, as tap water can contain particles that are harmful to its health. The reason that the water should be at room temperature or slightly warmer is that the Rock purslane comes from a warm environment, and cold water can be somewhat of a shock to its system. Also, you should avoid overhead watering for this plant, as it can cause foliage complications. Instead, simply apply your filtered room temperature water to the soil until the soil is entirely soaked. Soaking the soil can be very beneficial for this plant as it moistens the roots and helps them continue to spread through the soil and collect the nutrients they need.

What should I do if I water my Rock purslane too much or too little?

Both overwatering and underwatering will be detrimental to the health of your Rock purslane, but overwatering is a far more common issue. When this species receives too much water, its stems and leaves may begin to wilt and turn from green to yellow. Overwatering over a prolonged period may also lead to diseases such as root rot, mold, and mildew, all of which can kill your plant. Underwatering is far less common for the Rock purslane, as this plant has decent drought tolerance. However, underwatering remains a possibility, and when it occurs, you can expect to find that the leaves of your Rock purslane have become brittle and brown.

It is crucial that you notice the signs of overwatering as soon as possible when caring for your Rock purslane. Some of the diseases that arise from overwatering, such as root rot, may not be correctable if you wait too long. If you see early signs of overwatering, you should reduce your watering schedule immediately. You may also want to assess the quality of soil in which your Rock purslane grows. If you find that the soil drains very poorly, you should replace it immediately with a loose, well-draining potting mix. On the other hand, if you find signs that your Rock purslane is receiving too little water, all you need to do is water more regularly until those signs have subsided.

How often should I water my Rock purslane?

If your plant is in a pot. The most precise way to decide whether your Rock purslane needs water is to plunge your finger into the soil. If you notice that the first two to three inches of soil have become dry, it is time to add some water.

If you grow your Rock purslane outdoors in the ground, you can use a similar method to test the soil. Again, when you find that the first few inches of soil have dried out, it is time to add water. During the spring and early fall, this method will often lead you to water this plant about once every week. When extremely hot weather arrives, you may need to increase your watering frequency to about twice or more per week. With that said, mature, well-established the Rock purslane can show an admirable ability to withstand drought.

How much water does my Rock purslane need?

When it comes time to water your Rock purslane, you should not be shy about how much water you give. With the first two to three inches of soil dry, this plant will appreciate a long and thorough watering. Supply enough water to soak the soil entirely. The amount of water you add should be enough to cause excess water to flow through the drainage holes at the bottom of your pot. If you don’t see excess water draining from the pot, you have likely underwatered your plant. But do not let the water accumulate inside the soil, which will be very dangerous to the plant as well. Alternatively, a lack of water draining through the pot could indicate poorly draining soils, which is detrimental to the health of this plant and should be avoided. If the plant is outside, 1 inch of rain per week will be sufficient.

How should I water my Rock purslane at different growth stages?

The water needs of the Rock purslane can change depending on growth stages as well. For example, when your Rock purslane is in the first few years of its life, or if you have just transplanted it to a new growing location, you will need to give more water than usual. During both of those stages, your Rock purslane will put a lot of energy towards sprouting new roots that will then support future growth. For those roots to perform their best, they need a bit more moisture than they would at a more mature phase. After a few seasons, your Rock purslane will need much less water. Another growth stage in which this plant may need more water is during the bloom period. Flower development can make use of a significant amount of moisture, which is why you might need to give your Rock purslane more water at this time.

How should I water my Rock purslane through the seasons?

The Rock purslane will have its highest water needs during the hottest months of the year. During the height of summer, you may need to give this plant water more than once per week, depending on how fast the soil dries out. The opposite is true during the winter. In winter, your plant will enter a dormant phase, in which it will need far less water than usual. In fact, you may not need to water this plant at all during the winter months. However, if you do water during winter, you should not do so more than about once per month. Watering too much at this time will make it more likely that your Rock purslane will contract a disease.

What's the difference between watering my Rock purslane indoors and outdoors?

It is most common to grow the Rock purslane indoors for any gardener that does not live in temperate and tropical regions. Those gardeners should consider the fact that soil in a container can dry out a bit faster than ground soil. Also, the presence of drying elements such as air conditioning units can cause your Rock purslane to need water on a more frequent basis as well. if you planted it outside. When that is the case, it’s likely you won’t need to water your Rock purslane very much at all. If you receive rainfall on a regular basis, that may be enough to keep your plant alive. Alternatively, those who grow this plant inside will need to water it more often, as allowing rainwater to soak the soil will not be an option.

Does my Rock purslane need to be pruned?

The usual goal for the Rock purslane is to have it grow as big and full as possible. While the plant doesn’t require consistent trimming, it can benefit by removing old flowers and any damaged, dead, or diseased leaves. You can also trim back the leaves if it is starting to get too big for the pot and space you are keeping it.

When is the best time to prune my Rock purslane?

Rock purslane don’t have a winter dormancy cycle at the suitable temperature. With that said, their growth does slow down as the days get shorter, however the leaves don’t die. What does that mean for pruning? It means there’s no specific season where it’s better to prune. Ideally, you will want to wait until the flower blooms before pruning it, which can take about a month after the appearance of the blossom. With deadheading, you’ll want to do this around late spring or when only a few of the blossoms have faded. You should always prune brown or yellow leaves when you notice them. Throughout the growing phase, make sure to pay close attention to any potential diseased leaves and remove these as necessary.

What should I do after pruning my Rock purslane?

Once you’ve pruned your plant, you should dispose of the stems and leaves either by composting the healthy ones or throwing out the diseased parts. You can also fertilize just before or after pruning, which gives Rock purslane a little vitamin boost that can provide it the nutrients needed to better protect itself from any nearby pathogens or diseases. You don’t need much after care when you’re done pruning. It might benefit from light watering and some liquid plant food to encourage new blooms and growth.

How can I prune my Rock purslane during different growth stages?

Chances are you’re not getting the Rock purslane from seed, which means you’re already getting a mature plant. Since the plant doesn’t have a true dormancy cycle, there are really only two phases: blooming and non-blooming. While the plant is blooming, you should only remove yellow or dead leaves and cut off any brown tips on the leaves. Avoid doing too much pruning during this time as it can stress the plant. Still, you should remove any diseased or dead leaves to keep your plant presentable. The best time to prune is after the blossoms have already wilted. You can remove both the spent blossoms and any old and yellowed leaves at the same time. If you’re noticing a large amount of yellow leaves, you might be overwatering your plant or not giving it enough nutrients. While yellow or brown leaves don’t always mean there’s an issue, if you notice a large amount of leaves shifting colors, it usually means there’s a problem with the plant.

How can I prune my Rock purslane during different seasons?

As an evergreen plant, Rock purslane doesn’t have the same cycles as those found in colder areas. The leaves will remain green throughout the year, which is one of the many reasons it is a popular houseplant. If you want to deadhead, you should do so after the blossoms have already wilted. Throughout the growing phase, make sure to pay close attention to any potential diseased leaves and remove these as necessary.

Are there any instructions for pruning my Rock purslane?

How you prune the Rock purslane will depend on whether you’re performing general care or deadheading. For general care, simply cut off the blossoms that have already died. Make sure to get as close to the base as possible and snip at a 45-degree angle. Repeat this for all stalks with wilting blooms. After that, trim back any outer leaves that are old and yellowing. If you simply want to thin the plant out, start with the outermost leaf and work your way in. Avoid removing more than 30 percent of the leaves at once. Throughout the growing phase, make sure to pay close attention to any potential diseased leaves and remove these as necessary.

What type of sunlight does Rock purslane need?

Rock purslane needs full sun every day, and these plants rely on a minimum of six hours of sunlight to keep their leaves, roots, and blooms in a healthy state. Even though most perennials need six hours of sunlight a day, plants like the Orange Daylily or Giant Coreopsis could live off less sun for a minimum of three hours daily. Even though these perennial flowering plants can live with only three hours of direct sunlight, they won't be able to thrive like they would in sunnier conditions.

Can sunlight damage Rock purslane? How to protect Rock purslane from the sun and heat damage?

The few Perennial Flowering Plants that don't like excessive heat in warm climates might react poorly to too much sun if they have heat damage. These plants may wilt or dry out from too much sun and may also develop growth issues if they're regularly in the sun during the most intense heat of the day. Some plants don't need protection from the light afternoon sun, but those that are harmed by intense afternoon exposure should be provided some shade in warmer climates. Gardeners could give these plants plenty of shade by planting them in spots that don't receive direct heat during the afternoon, like under trees or behind bushes.

Should I protect Rock purslane from sun exposure?

While many perennial plants need plenty of sun to bloom to their fullest extent, some of them benefit from less sun in warmer climates. For example, people who live in hotter climates might want to provide shade for their flowering perennials in the hot afternoon sun, and this is even more true for months in the summer.

Even though some perennial flowering plants will benefit from partially shaded in the hottest climates, plants like the Giant Coreopsis aren't intimidated by too much sun. They might sit outside in the full sun in hot weather and still thrive.

What will happen if Rock purslane gets inadequate sunlight?

If you're growing Rock purslane and you aren't getting enough sunlight, you'll notice signs of inadequate requirements in your plants. Most plants won't produce as many blooms as they would if they had full sun exposure. Some plants will develop dry spots on their leaves, but most of these plants will still bloom in the inadequate sun. Even though they bloom, the flowers will be smaller and less full.

Does Rock purslane need special care about sunlight during its different growth stages?

Rock purslane is great flowers in gardens and will have optimum blooming if it gets six hours of sunlight a day minimum. Sometimes, flowers stay fresh longer if they're partially shaded during the really hot parts of the day. When Rock purslane is young, gardeners want to ensure their younger plants are getting plenty of sunlight but don't have to endure intense heat during the afternoon sunlight. If you have a fully mature plant, provide it with plenty of sun so it may keep up its growth properly.

How much light does Rock purslane need for photosynthesis?

Rock purslane will need a minimum of six hours of light to best support their photosynthesis cycles. These flowering plants need the sun to help their foliage and blooms grow. However, certain perennial flowering plants like the Giant Coreopsis might need anywhere from eight to twelve hours of full sun a day to maintain their large flowers and healthy foliage.

How much light should Rock purslane get per day to grow healthily?

If you want your Rock purslane to grow healthy and bloom as much as possible during its blooming season, you should try to give your plant six hours of direct sunlight. Some perennial plants might even do more sunlight and could sit in the sun for up to twelve hours, depending on the heat in the area and the general environment. Plants like the Red Hot Poker and Giant Coreopsis thrive in much hotter climates and might sit in all types of strong sunlight.

Some home gardeners have to use grow lights because their spaces don't allow for tons of outdoor sunlight. Most perennials could grow happily in grow lights, but they will need anywhere from eight to fourteen hours of artificial light to stay strong since these lights don't have as much power as the sun.

What is the optimal temperature for Rock purslane?

Colder temperatures can affect plants since they have the same temperature as the air around them. When they are exposed to the sun, they can start to get warm again, but this is not the case during winter. The temperature range for the Rock purslane is often 70~85℉(21~30℃). They might tolerate 20~30℉(-6~0℃) even 15℉(-10℃), but not for long since this can result in frost damage. Maximum temperatures should be around 70~85℉(21~30℃), but make sure that you spray them with water from time to time and give them some shade to prevent wilting.

Should I adjust the temperature for Rock purslane during different growing phases?

Do some research and make sure that the temperature is right when growing Rock purslane. Some growers might consider decreasing the plants' thermostats during the growing season to reduce HVAC costs. However, it's vital to understand that the temperature can affect the flowering, pest management, and quality of the plants.

There will be a temperature point where the Rock purslane will stop growing, and this can happen during the winter when some species might go into a dormant state. The base temperature becomes warmer when the season changes and the Rock purslane can grow faster. The species that are naturally growing in warm habitats have higher optimum temperatures when you compare them to the ones that thrive in a cooler climate.

When the seeds of Rock purslane are exposed to cool temperatures, this can cause a decrease in uniformity and delays. You might also want to lower the temperature during flowering but not at other phases. Cooler temperatures at night will also require less water, so adjust the irrigation as needed.

How can I keep Rock purslane warm in cold seasons?

Stop fertilizing the plant to avoid new growth and allow the old ones to become hardy. This way, they can endure colder temperature when it begins to drop. To keep them warm, you can build structures around the Rock purslane like cages or trellises. There are also options to use heat mats that can gently warm the soil since they can consistently maintain an ideal temperature range for the Rock purslane.

How can I save Rock purslane from temperature damage?

During winter, you can protect the Rock purslane from frost by covering it with cloths, tarps, burlaps, sheets, or plastic buckets. Make sure to keep them down so they continue to act as insulators and the wind will not blow them away. However, ensure that the plastic sheets or burlap covers should not touch any part of the fruit or foliage, or the cold temperatures can transfer to the material and cause burns. When the temperatures begin to rise during the daytime, remove the covers.

Should I adjust the temperature for Rock purslane in different seasons?

When growing the Rock purslane in spring, you might want to increase humidity since the air temperature tends to be cooler at this time. A dry temperature can be a stressful growing environment for various species, which can help. If summer arrives, the large cover of the greenhouse and the warm temperature will mean that there will be a higher humidity level in the air. Some signs to look for are the condensation that is often found on the walls of the greenhouse, and this can cause issues with pollination and the development of infections when the water begins to fall on the leaves. Make adjustments according to the temperature and do some spraying during the hotter days of the year.

What damage will Rock purslane suffer if the temperature is too high/low?

Generally, the first cold snap can destroy the Rock purslane and others might go into a dormant state when the temperature is low. Some plants can get chilled when the temperatures range from 20~30℉(-6~0℃). They can freeze when the temperature begins to drop below 32℉(0℃). Those species that hide most of their parts under the soil might lose their structures above ground, but they can recover in spring. Some of the associated issues with too low temperatures are the lack of availability of resources like water, and nutrients, and those subtropical plants can suffer when the temperature reaches below 20℉(-6℃). The plants can also get damaged because of extreme heat stress when it's too high. This can reduce the transpiration rate that can affect the growth and productivity of Rock purslane.

What tips and cautions should I keep in mind when it comes to temperature for Rock purslane?

You need to cover the plants at night since these can add about 5 degrees more to protect the species from frost and freezing temperatures. The cloth rows can work well as blankets and ensure that there are no openings where the heat could escape.

When using the covers, avoid the plastic from touching the foliage because this can cause the Rock purslane to freeze. Remember to keep the covers during the day and stop using heat pads during the summer. It will always be worth the effort to protect the cold-intolerant plants from freezing temperatures to help them survive.

How can I keep Rock purslane warm without a heat pad?

If you prefer not to use a heat pad, bring the Rock purslane inside, especially if it's freezing outdoors. During spring, consider the ones you need to bring indoors and plant them in moveable pots and containers.

How can I provide Rock purslane with an adequate temperature condition?

Most often, the ones caring for the Rock purslane will grow them in greenhouses. This is because they can provide adequate temperature in these areas that won't affect the photosynthesis process of a specific process.

Some install the proper HVAC systems to control the temperatures of Rock purslane. This can handle many species' cooling and heating needs, especially during the summer and winter. They generally place the cooling or heating pad under the plants rather than above to achieve their desired temperatures.

If outdoors, you can protect the Rock purslane from frost by covering it with cloths, tarps, burlaps, sheets, or plastic buckets.

Under what conditions should I stop adjusting the temperature for Rock purslane?

Heat mats are often left on Rock purslane to set the temperatures at a more consistent level. When the weather becomes warmer during the day, you can remove them, especially if the species are exposed to the sun. Put the pads away once the plants are established and when they start growing flowers and fruits.

Why do I need to fertilize my Rock purslane?

Fertilization is important to the Rock purslane for several general reasons. Mainly, fertilization helps Rock purslane and other plants by providing key nutrients that help the plant grow both above and below ground. However, the overall fertilization needs for a Rock purslane are relatively low.

At times, a Rock purslane may survive well without fertilization. However, annual fertilization is can be very beneficial to the Rock purslane, as it will help keep the plant alive and may also encourage your Rock purslane to create better flowers that last for longer. As such, those interested in helping their Rock purslane look its best should keep up with annual fertilization.

When is the best time to fertilize my Rock purslane?

The ideal time to fertilize a Rock purslane is in the late winter to early spring. During that time, your Rock purslane will be exiting its dormant phase and entering a phase of active growth. Fertilization at this time allows the plant to get off to a great start for the season by encouraging healthy growth.

While it is generally most advantageous to fertilize a Rock purslane during the early spring, it is also permissible to fertilize a Rock purslane during the fall too. However, summer and winter remain the seasons in which it is not a good idea to feed a Rock purslane.

When should I avoid fertilizing my Rock purslane?

You should not fertilize your Rock purslane during any time of the year except during the late winter and early spring. The low fertilization needs of this plant allow a single annual feeding to suffice. Continuing to fertilize throughout spring, summer, and fall can easily lead to overfertilization and all of the complications that can come with it. The only exception is if you did not fertilize in spring, which means that it is permissible to feed this plant in fall.

Along with refraining from fertilizing for most of the growing season, there is also no reason to fertilize this plant during the winter. In winter, the Rock purslane will be in a dormant growth phase, meaning that it does not put forth new growth. With that being the case, fertilization during most of the winter is not advisable.

What type of fertilizer does my Rock purslane need?

Nearly any kind of general-purpose fertilizer with a balanced amount of the three main plant nutrients will work well for a Rock purslane. However, there are a few specific nutrient blends that can be even more beneficial. For instance, many gardeners follow the belief that higher volumes of phosphorus make for stronger roots and better flowers. Since Rock purslane is a flowering plant, applying a phosphorus-rich fertilizer may be the best approach.

You can use a fertilizer that comes in a granular form or a liquid form as long as there are plenty of nutrients present. Outside of manufactured fertilizers, you can also use more organic means to improve the soil for your Rock purslane. Mainly, compost, manure, and similar materials can go a long way towards creating a healthy growing medium for your Rock purslane.

How do I fertilize my Rock purslane?

The most common way to fertilize a Rock purslane is to apply a granular or pellet fertilizer to the soil around your plant. Remember that the ideal time to fertilize is as the plant is exiting its winter dormant growth phase and entering a phase of active growth. In early spring, wait until the plant begins to send shoots through the soil, and then apply your fertilizer.

Some people may choose to use a liquid fertilizer instead of a granular one. In that case, you should dilute the fertilizer with water before applying it. Regardless of whether you use granular or liquid fertilizer, it is always best to moisten the soil before, during, and after you apply fertilizer.

What happens if I fertilize my Rock purslane too much?

As you care for your Rock purslane, recall that this plant does not need a lot of fertilizer each year and will begin to suffer if it receives too much. Firstly, any overfertilized plant runs the risk of fertilizer burn, a condition in which excessive amounts of fertilizer draw nutrients and moisture out of the plant's roots, causing its decline.

Also, overfertilizing a Rock purslane is also a way of weakening your plant and making disease far more likely. There is also a potential that overfertilization could cause your Rock purslane to flower less or not at all, which is a significant detriment considering the blooms of this plant are what make it so valuable and sought after by so many gardeners.

Common Pests & Diseases About Rock purslane

Feedback

Common issues for Rock purslane based on 10 million real cases

Leaf rot

This pathogen can cause the leaves to rot.

Solutions: Bacterial infections need to be treated quickly to prevent the spread to neighboring, healthy plants, potentially wiping out large sections of your indoor or outdoor garden. In mild cases: Use sterilized (10% bleach solution) pruning shears or scissors to remove any infected plant parts, making sure to dispose of them off site. Use a copper-based bactericide to treat the unaffected foliage, as well as the soil, and neighboring plants. Follow the manufacturer’s rate and timing directions found on the product label. In severe cases, where more than half the leaves are affected: Remove all of the infected plants from the garden, disposing of them off site. Treat the soil and neighboring plants using a copper-based bactericide. Follow the manufacturer’s rate and timing directions found on the product label.

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.

Plant dried up

The entire plant may dry out due to dieback or normal seasonal dormancy.

Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.

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

Symptoms of Insufficient Light in %s

Rock purslane thrives in full sunlight and is commonly grown outdoors where it receives ample sunlight. When placed in rooms with inadequate lighting, symptoms of light deficiency may not be readily apparent.

(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 Rock purslane 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

Rock purslane 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.

Symptoms of Excessive light in %s

Rock purslane thrives in full sun exposure and can tolerate intense sunlight. With their remarkable resilience, symptoms of sunburn may not be easily visible, as they rarely suffer from it.

(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.
