What is the best way to water my Chinese crown orchid?
The manner in which you water the Chinese crown orchid will depend somewhat on whether or not your plant is in an active growth phase. If so, you should apply water to your plant’s soil and, if the weather is warm, perform occasional overhead watering to allow the plant to absorb moisture through its leaves. By contrast, in winter, and when the weather is cool or wet generally, you should stick to watering the soil directly rather than including overhead watering as well. You’ll know your Chinese crown orchid needs more water if its roots and leaves become thin and dry or show discoloration. Chinese crown orchid receives too much water will look mushy and limp. You should grow your Chinese crown orchid in a pot and ensure that the potting mix you use has fantastic drainage. During the growing season, you’ll need to water this plant multiple times per week. However, each watering should drain quickly through the growing medium to prevent any standing water. The amount of water you give will change based on the size of the pot you use. Generally, pots that are a bit larger will need water less frequently, while smaller pots will have a slightly more frequent watering schedule. Rainwater and distilled water are the best kinds of water to use for this plant, and it is best if the water you use matches the temperature of the air as closely as possible.

What should I do if I water my Chinese crown orchid too much or too little?
Allowing your Chinese crown orchid to sit in soil that remains too moist for too long is one of the most common ways to kill this plant. While these plants need water frequently during active growth, they also need to live in a growing medium that drains water rapidly. When this plant experiences overwatering, it will become mushy and develop root rot. If that occurs, you should be prepared to use a pair of sterile pruning shears to cut out any roots that show signs of rot. After doing that, you should then repot your Chinese crown orchid, ensuring that the container allows for drainage and that you fill the container with a fast-draining potting mix. However, Chinese crown orchid doesn’t typically respond that well to excessive repotting, so it is crucial to get your watering rate right. Underwatered Chinese crown orchid will begin to shrivel and feel dry to the touch. If this occurs, it is likely because the soil is drying out faster than you expected, which means you should increase your watering frequency.

How often should I water my Chinese crown orchid?
During the active growth stage, which spans the spring and summer months, you should plan to water your Chinese crown orchid about once or twice per week while increasing that rate to three times per week or more in the case of long periods of hot and dry weather. In the winter, you will also need to water your Chinese crown orchid, but not nearly as much. A watering frequency of two to three times per month should be enough to keep your Chinese crown orchid alive during the coldest months. However, if you keep your Chinese crown orchid indoors during winter, you should account for the fact that indoor growing locations can cause the soil to dry quicker than usual, which may mean you need to increase the number of monthly waterings. You can use the fall as a time to gradually reduce your watering frequency from the summer rate of multiple times per week down to your reduced winter watering schedule.

What should I consider when watering my Chinese crown orchid in different seasons and growth periods?
There are two important growth phases that you should consider when planning the watering schedule for your Chinese crown orchid. The first of those periods is the active growth period, which happens in spring and summer, and which calls for watering this plant multiple times per week. The second important growth period is the rest period that the Chinese crown orchid should experience for about two to three months each year during winter. During that time, your plant will need far less water and fertilization than normal. Water about once or twice per month during this time. During the fall, you should begin to gradually reduce your watering frequency from multiple times per week all the way down to the once or twice per month rate that is appropriate for winter.

How should I water my Chinese crown orchid differently if I grow it indoors?
The Chinese crown orchid requires a growing environment that is relatively humid. Unfortunately, most indoor growing locations will lack the level of air moisture that this plant prefers. This causes the plant and its soil to dry out more quickly than it would when growing outdoors. To combat this effect, you may want to include a humidifier in the room where you grow your Chinese crown orchid. You may also need to water it a bit more frequently as well. However, while Chinese crown orchids do prefer humidity, they also require adequate air circulation as well, to prevent excessive moisture build-ups and the diseases that can result. Consider including a fan in the room where you grow this plant as well to ensure proper air circulation remains present.

(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 Chinese crown orchid 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
Chinese crown orchid 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
Chinese crown orchid thrives in full sun exposure but is more prone to sunburn during summer. When placed outdoors in high-temperature environments, they may suffer from sunburn due to their limited tolerance to intense sunlight.

(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.
