What is the best way to water my Yellow pitaya?
It's important to know various ways to water the Yellow pitaya. Some might ask whether they should do the watering from top to bottom, or is it the opposite? According to the experts, one of the best ways to water the cactus is to start from the bottom. This will ensure that there will be enough water to reach the root of the plants. If you're starting from the top, there will not be enough saturation. The water will trickle and evaporate, and only a small amount will reach its roots.

What should I do if my Yellow pitaya is underwatered?
Sometimes, you might notice that even if you water it frequently enough, it will start to dry out. When you see that the flowers are beginning to wilt and there's not enough water, the issue might be in the container where they are planted. Choose a bigger one if this is the case. Buy a pot that drains easily. You will need to mix it with the right potting soil and clean sand so it will absorb more water easier. The soil that is too wet will not go well with the roots. Since this species is an epiphyte, it won't be able to handle soggy roots since it absorbs water and nutrients from the air. It's best to ensure that there's proper drainage to prevent fungal infections. When you notice the cactus is limp, you can transfer or re-pot it into fresh earth. Gently remove the soil as much as possible and keep it evenly moist. Mist the cactus frequently whenever possible. After the flowers have finished blooming, you might want to cut back on watering until you see new buds appearing. When the soil dries too much, the buds will begin to drop, so you might want to add some water but not too much. Sometimes, underwatering, which is followed by overwatering that many owners do for compensation, is quite common. These cacti are considered to be succulents. The lack of water is not noticeable until everything is too late. They show that there are issues when they begin to droop and wither. The well-intentioned plant owner will give them massive amounts of water. This is where the roots become desiccated. They become so dry that they can't take in any excess water. It will result in waterlogged plants, and the remaining roots may rot. If you notice some signs of wilting or underwatering, you can try to bring the species back to life with regular and frequent watering. However, make sure that it won't be a deluge, so you'll give the cactus a chance to regenerate and recover its roots.

How much water should I give my Yellow pitaya?
The Yellow pitaya must be properly watered to keep it healthy all year round. It should be potted in well-draining soil so it would produce beautiful blooms. The amount of water that the Yellow pitaya needs can vary. When you see that about 1/3 of the topsoil is dry, this is the best time to water them. They are thirstier than the other succulents, so watering should take place about 1x every week. Use your fingers to check if the soil is about two inches dry. If you notice that the soil is very dry on the top layer, run the water until it goes through the drainage of the pots. There should be a tray underneath to catch the extra water. After about 10 to 15 minutes, discard everything, including the excess water. The soaking method should work well with the Yellow pitaya but don't let it sit on the water-filled pot for a long time. When the species is in its flowering stage, it's highly recommended to water it sparingly. Ideally, the best time to water them is when you notice that the leaves begin to droop. Make sure to fill the saucer of the pots with pebbles. Add water to the pebbles to add humidity to your Yellow pitaya. The best way to understand whether it's time to water the Yellow pitaya is to check the soil. When it's too dry, simply add water and moisture. However, don't let the pot sit in the water, especially during the winter when the soil takes a long time to dry. This can cause root rot. Know that these species can react to various seasonal changes. Watering it the correct way will mean that you should consider the climate. If you live in a dry and hot climate, the plants will need more watering, which is about twice per week. If you live in a humid area, then watering only 1x a week can work well. You should water this less frequently in the fall and winter if you want the flowers to bloom. When the pots are exposed to too much sunlight, then the moisture will dry out faster. This is when the plant needs more watering. Watering should be less if it is in a cool or humid place.

What will happen if I overwater my Yellow pitaya?
Sometimes, you might overwater your Yellow pitaya, which makes it look limp or wilted. When you've neglected it for too long, give it a little drink. Continue to provide it with water in a sparing way until you see that there's slight moisture in the soil. Overwatering can cause the development of a fungal infection called white rot. The leaves tend to droop, which might result in wilting. Like any other species, the cactus can't stand overwatering or underwatering. They don't tolerate dry soil since the flowers will start dropping at the same time, and this is something that you don't want to happen.
Read More more
Should I adjust the frequency of watering my Yellow pitaya according to different seasons?
The cold months and the hot months are not the same. The temperatures tend to drop during the winter and fall, and the soil will take longer to dry. This is when you don't need to water the succulents often. These two seasons are also the best time for the Yellow pitaya to show its beautiful blooms. Water sparingly to maintain the health of the plant. During the months of October, stop watering when there's too much water in the soil. Resume the care in November but keep the moisture light when the temperatures are still cool. When the blooms start to appear, stop watering for about a few weeks so the plants can rest from too much moisture. These are very delicate, so when you see new growth, you can resume the watering once a week if you need to.

Should I water my Yellow pitaya differently when I plant it indoors vs outdoors?
Your plant's location is something you need to consider when it comes to its watering needs. When the plant grows near the window or outdoors, the air might be too dry, and the temperatures are too high. This is where you should water the plant for about 2x a week. When it's growing indoors in a humid and cool environment, it will definitely need less watering. Indirect sunlight will also have an impact since the soil does not tend to dry out faster. This is where the succulent will just be fine with once-a-week watering. However, you still need to check the soil with a moisture meter to know what it needs.

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.
Flower withering

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.

Scars
Any light-colored markings that appear on stems but which do not enlarge or multiply are simply scars that have healed.
Symptom Analysis
Symptom Analysis
Scars form when the plant repairs wounds. They can be the result of people or pets passing by and scraping the plant. Once the underlying issue is resolved, the plant will heal but a scar may remain.
Pests and pathogens can also cause scarring. Insects may attack the plant for a meal, resulting in extensive scarring when a few invaders turn into an infestation. Diseases such as fungus and bacteria can weaken the plant, causing brown spots, mushy areas, or blisters that lead to scars.
Scars occur on stems when a leaf or bud has been lost and the plant has healed. The harder tissue is like a scab that protects a wound.
On other occasions, scars can signal problems from environmental conditions, such as overexposure to sunlight or heat. It might surprise you to know that plants can suffer from sunburn, even desert dwellers like cactus!
Solutions
Solutions
Each source of scarring requires a different approach to help your plant recover.
  1. Protect the trunk and leaves from physical damage like scrapes.
  2. 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.
  3. Stop sunburn by moving your plant away from direct sunlight and making sure it has the water it needs.
  4. Frequent leaf or bud loss may be due to insufficient light or nutrients.
Prevention
Prevention
Preventing some sources of scarring is easier than others, but all start with careful attention to your plants once you decide to bring them home.
  1. Review specific guidelines for your plant, including soil drainage, watering, and fertilizer requirements.
  2. Inspect plants before planting and use sterile pots and fresh potting soil or media to limit transfer of fungi or bacteria.
  3. Once established, check your plants regularly for signs of scarring or the presence of pests, as it is better to catch problems as early as possible.

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.

Lighting
Full sun
Yellow pitaya thrives under strong solar exposure and can flourish with moderate light. An abundance of sunlight promotes its healthy growth and enriches its yellow hue. Though it can withstand some degree of shade, inadequate sunlight may dull its color and hamper development. Its original habitat exhibits high solar intensity. Overexposure could lead to scorched skin, while underexposure might restrict growth.
Best Sunlight Practices
Transplant
10-12 feet
For the robust growth of yellow pitaya, the best timing aligns with the warmth and renewal of early summer, ensuring a smooth transition. Choose a sunny, well-drained location, and during the process, handle yellow pitaya's roots with care to avoid damage.
Transplant Techniques
Temperature
5 - 43 ℃
Yellow pitaya is native to environments that enjoy temperatures between 68 to 100 °F (20 to 38 ℃). It thrives best when the temperature is maintained in this range. Seasonal adjustments might be necessary to mimic its natural habitat.
Temp for Healthy Growth
Propagation
Spring,Summer
Yellow pitaya is typically propagated through stem cuttings, an effective practice for ensuring a genetically identical clone of the parent plant. To achieve successful rooting, a cutting should be taken from a healthy and vigorous stem, ideally with several notches or nodes. After cutting, allow the end to callous over for a few days to prevent rot when planted. Using a well-draining cactus or succulent mix, place the cutting in the soil, anchoring it to avoid displacement. Consistent moisture and warmth will encourage root development without saturating the cutting, which could lead to decay. Indirect light aids in the process without causing sunburn to the new plant.
Propagation Techniques
Overwinter
5 - 43 ℃
Yellow pitaya hails from the tropics, naturally dodging cold winters. Adapting this species to a winter setting can be tricky. Indoor growth is a must when temperatures drop below 32°F (0°C). Gardeners should maintain a humidity level of 50-80% and a daytime temperature around 70°F (21°C) to mirror yellow pitaya's native conditions. Sanitize the heater regularly to combat pests, common in heated indoor environments.
Winter Techniques
Scars
Scars on Yellow pitaya are physical damage typically caused by external mechanical injuries, affecting the plant's aesthetics and potentially its growth. The impact can range from minor surface marks to severe tissue damage that impairs functionality.

Any light-colored markings that appear on stems but which do not enlarge or multiply are simply scars that have healed.
Symptom Analysis
Symptom Analysis
Scars form when the plant repairs wounds. They can be the result of people or pets passing by and scraping the plant. Once the underlying issue is resolved, the plant will heal but a scar may remain.
Pests and pathogens can also cause scarring. Insects may attack the plant for a meal, resulting in extensive scarring when a few invaders turn into an infestation. Diseases such as fungus and bacteria can weaken the plant, causing brown spots, mushy areas, or blisters that lead to scars.
Scars occur on stems when a leaf or bud has been lost and the plant has healed. The harder tissue is like a scab that protects a wound.
On other occasions, scars can signal problems from environmental conditions, such as overexposure to sunlight or heat. It might surprise you to know that plants can suffer from sunburn, even desert dwellers like cactus!
Solutions
Solutions
Each source of scarring requires a different approach to help your plant recover.
  1. Protect the trunk and leaves from physical damage like scrapes.
  2. 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.
  3. Stop sunburn by moving your plant away from direct sunlight and making sure it has the water it needs.
  4. Frequent leaf or bud loss may be due to insufficient light or nutrients.
Prevention
Prevention
Preventing some sources of scarring is easier than others, but all start with careful attention to your plants once you decide to bring them home.
  1. Review specific guidelines for your plant, including soil drainage, watering, and fertilizer requirements.
  2. Inspect plants before planting and use sterile pots and fresh potting soil or media to limit transfer of fungi or bacteria.
  3. Once established, check your plants regularly for signs of scarring or the presence of pests, as it is better to catch problems as early as possible.

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.
Solutions
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.
Prevention
Prevention
This is definitely one of those instances where prevention is more effective than cure. Here are some preventative measures for avoiding premature flower withering.
  • Water plants according to their needs -- either keep the soil slightly moist or allow the top inch or two to dry out before watering again.
  • Fertilize lightly on a consistent basis, depending upon the plant’s growth. Quick-growing plants and those that flower or develop fruit will need more frequent fertilizing than slow-growing plants.
  • Purchase plants that are certified disease- or pathogen-free.
  • Look for disease-resistant cultivars.
  • Isolate plants showing disease symptoms to prevent the spread to neighboring plants.
  • Practice good plant hygiene by removing any fallen plant material as soon as possible.

Aged yellow and dry

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.
Solutions
Solutions
If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Prevention
Prevention
Unfortunately, there is no way to prevent plants from dying of “old age.” To help prolong their life, and put off symptoms of aged yellow and dry for as long as possible, take care of them by giving them enough water, fertilizing them appropriately, and making sure they get enough sunlight.

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
Yellow pitaya thrives in full sunlight but can tolerate partial shade. However, when cultivated indoors during winter, it's often placed in rooms with insufficient lighting, leading to easily noticeable 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 Yellow pitaya 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
Yellow pitaya 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
Yellow pitaya thrives in full sun exposure but can also tolerate partial shade. They have a remarkable resilience to intense sunlight, and symptoms of sunburn may not be easily visible.

(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.

Essentials
Yellow pitaya is native to environments that enjoy temperatures between 68 to 100 °F (20 to 38 ℃). It thrives best when the temperature is maintained in this range. Seasonal adjustments might be necessary to mimic its natural habitat.
Regional wintering strategies
Yellow pitaya is extremely heat-loving, and any cold temperatures can cause harm to it. In the autumn, it is recommended to bring outdoor-grown Yellow pitaya indoors and place it near a bright window, but it should be kept at a certain distance from heaters. Maintaining temperatures above {Suitable_growth_temperature_min} during winter is beneficial for plant growth. Any temperatures approaching {Tolerable_growing_temperature_min} are detrimental to the plant.
Important Symptoms
Symptoms of Low Temperature in Yellow pitaya
Yellow pitaya prefers warm temperatures and is not tolerant of low temperatures. It thrives 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 leaves may lighten in color. After frost damage, the color gradually turns brown or black, and symptoms such as wilting and drooping may occur.
Solutions
Trim off the frost-damaged parts. Immediately move indoors to a warm environment for cold protection. Choose a spot near a south-facing window to place the plant, ensuring ample sunlight. Additionally, avoid placing the plant near heaters or air conditioning vents to prevent excessive dryness in the air.
Symptoms of High Temperature in Yellow pitaya
During summer, Yellow pitaya should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the color of the leaves becomes lighter, and the plant becomes more susceptible to sunburn.
Solutions
Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun. Water the plant in the morning and evening to keep the soil moist.
