What is the best way to water my Cymbidium orchid?
The manner in which you water the Cymbidium 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 Cymbidium orchid needs more water if its roots and leaves become thin and dry or show discoloration. Cymbidium orchid receives too much water will look mushy and limp. You should grow your Cymbidium 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 Cymbidium orchid too much or too little?
Allowing your Cymbidium 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 Cymbidium orchid, ensuring that the container allows for drainage and that you fill the container with a fast-draining potting mix. However, Cymbidium orchid doesn’t typically respond that well to excessive repotting, so it is crucial to get your watering rate right. Underwatered Cymbidium 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.
Read More more
How often should I water my Cymbidium orchid?
During the active growth stage, which spans the spring and summer months, you should plan to water your Cymbidium 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 Cymbidium orchid, but not nearly as much. A watering frequency of two to three times per month should be enough to keep your Cymbidium orchid alive during the coldest months. However, if you keep your Cymbidium 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.
Read More more
What should I consider when watering my Cymbidium orchid in different seasons and growth periods?
There are two important growth phases that you should consider when planning the watering schedule for your Cymbidium 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 Cymbidium 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 Cymbidium orchid differently if I grow it indoors?
The Cymbidium 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 Cymbidium orchid. You may also need to water it a bit more frequently as well. However, while Cymbidium 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.

Root withering
Root withering is a destructive condition in Cymbidium orchid, leading to weakening and eventual plant death if untreated. It is primarily caused by poor watering habits and fungal infections, causing noticeable shrinkage and discoloration in the roots.
Aged yellow and dry
Aged yellow and dry Aged yellow and dry
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
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.
Brown spot
Brown spot Brown spot
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.
Anthracnose
Anthracnose Anthracnose
Anthracnose
Anthracnose causes grey-brown spots with black margins on leaves and stems.
Solutions: For less serious cases when only a few leaves are affected, complete the following: Prune affected leaves. Using pruning shears, remove leaves that have spots. Dispose of these leaves to avoid spreading the disease to other plants. Clear debris. To stop the spread of disease, remove debris and weeds from around plants. For serious cases when many leaves are infected with large splotches: Apply a fungicide. Fungicides won't cure current infections, but they will prevent anthracnose from spreading to uninfected tissue. Apply a fungicide before a dry period following product instructions. Products containing copper diammonia diacetate are most likely to be effective.

plant poor
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.

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.

Anthracnose
plant poor
Anthracnose
Anthracnose causes grey-brown spots with black margins on leaves and stems.
Overview
Overview
Anthracnose is a group of fungal diseases that affects foliage, twigs, and stems. It can affect a wide variety of plants including trees, shrubs, vegetables, grasses, and flowers and is most likely to occur in cool, wet conditions. It often occurs in the spring when rain splashes on overwintering fungi.
Some varieties of plants are bred to be resistant to anthracnose. If plants are not resistant, they can become infected year after year. Plants can also recover from infection only to be reinfected later that year.
In most cases, anthracnose only causes minor damage. However, young plants are susceptible to major damage. In the worst-case scenarios, this disease can cause major defoliation.
Symptom Analysis
Symptom Analysis
Plant leaves will show gray or brown blotches that may be surrounded by black edges. Blotches may be only one small spot or many spots that cover an entire leaf. If these symptoms progress, leaves may drop prematurely.
Anthracnose can also cause small lesions on twigs and stems. These often appear as brown, gray, or orange blisters. If left untreated, twigs may drop.
Disease Cause
Disease Cause
Anthracnose is caused by one of several possible fungi. These pathogens overwinter on plant debris. When water hits these fungi in the spring, spores release and land on plant tissue. When the spores germinate on leaf or twig tissue, they cause anthracnose symptoms.
These fungi need moist conditions to live. Therefore, they will not be a problem in dry conditions.

Prevention
Like many other diseases, it is easier to prevent brown spot than cure it, and this is done through cultural practices.
  • Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
  • Maintain good air movement between plants through proper plant spacing.
  • Increase air circulation through the center of plants through pruning.

Anthracnose
plant poor
Anthracnose
Anthracnose causes grey-brown spots with black margins on leaves and stems.
Overview
Overview
Anthracnose is a group of fungal diseases that affects foliage, twigs, and stems. It can affect a wide variety of plants including trees, shrubs, vegetables, grasses, and flowers and is most likely to occur in cool, wet conditions. It often occurs in the spring when rain splashes on overwintering fungi.
Some varieties of plants are bred to be resistant to anthracnose. If plants are not resistant, they can become infected year after year. Plants can also recover from infection only to be reinfected later that year.
In most cases, anthracnose only causes minor damage. However, young plants are susceptible to major damage. In the worst-case scenarios, this disease can cause major defoliation.
Symptom Analysis
Symptom Analysis
Plant leaves will show gray or brown blotches that may be surrounded by black edges. Blotches may be only one small spot or many spots that cover an entire leaf. If these symptoms progress, leaves may drop prematurely.
Anthracnose can also cause small lesions on twigs and stems. These often appear as brown, gray, or orange blisters. If left untreated, twigs may drop.
Disease Cause
Disease Cause
Anthracnose is caused by one of several possible fungi. These pathogens overwinter on plant debris. When water hits these fungi in the spring, spores release and land on plant tissue. When the spores germinate on leaf or twig tissue, they cause anthracnose symptoms.
These fungi need moist conditions to live. Therefore, they will not be a problem in dry conditions.
Solutions
Solutions
For less serious cases when only a few leaves are affected, complete the following:
  • Prune affected leaves. Using pruning shears, remove leaves that have spots. Dispose of these leaves to avoid spreading the disease to other plants.
  • Clear debris. To stop the spread of disease, remove debris and weeds from around plants.
For serious cases when many leaves are infected with large splotches:
  • Apply a fungicide. Fungicides won't cure current infections, but they will prevent anthracnose from spreading to uninfected tissue. Apply a fungicide before a dry period following product instructions. Products containing copper diammonia diacetate are most likely to be effective.
Prevention
Prevention
Since anthracnose is difficult to treat once it appears, it's important to prevent it from infecting your plants.
  • Remove debris. Clear all old plant material and weeds from under and around plants in the fall. This material can harbor anthracnose spores that will later infect plants.
  • Select resistant varieties. When adding new plants, choose varieties that are resistant to anthracnose.
  • Increase airflow. Anthracnose thrives in wet conditions, so space plants far enough apart to allow for good airflow.
  • Avoid overhead irrigation. To keep plant tissue dry, avoid using overhead irrigation. Instead, water at the base of plants or install drip irrigation.
  • Use a preventative fungicide. If there is a reason to suspect future anthracnose outbreaks, apply a fungicide in the early spring.

Basic Care Guide
Common Pests & Diseases
Root withering
Root withering is a destructive condition in Cymbidium orchid, leading to weakening and eventual plant death if untreated. It is primarily caused by poor watering habits and fungal infections, causing noticeable shrinkage and discoloration in the roots.
 detail
Leaf yellowing
Leaf yellowing is a common disease affecting Cymbidium orchid, causing its leaves to turn yellow. It's primarily caused by nutrient deficiencies, poor watering habits, inappropriate light or diseases and may lead to plant death if uncontrolled.
 detail
Leaf wilting
Leaf wilting is a potentially devastating disease affecting Cymbidium orchid, primarily characterized by drooping and browning of leaves. The disease negatively impacts photosynthesis, overall plant growth, and can cause plant death if untreated.
 detail
Flower stem withering
Flower stem withering is a significant health issue in Cymbidium orchid, resulting in damage and potential loss of the flowering stem. More than just an aesthetic problem, this disease can significantly impact overall plant health and longevity.
 detail
Leaf rot
Leaf rot is a fungal disease that can devastate Cymbidium orchid. It primarily affects the leaves causing them to yellow, wilt and eventually decay. Without proper treatment, leaf rot can significantly deter growth, and in severe cases, kill the plant.
 detail
Leaf wrinkling
Leaf Wrinkling is a common plant disease that affects the Cymbidium orchid, inflicting substantial damage to its aesthetic appeal and growth. This condition manifests as severe deformity, palpable wrinkling, and curling of leaves, hindering the plant's photosynthetic efficiency and stunted growth ultimately.
 detail
Leaf blotch
Leaf blotch is a harmful fungal disease, primarily caused by the Guignardia fungus, affecting Cymbidium orchid. Prominent symptoms include leaf spots and discoloration, typically in wet, warm environments. It can escalate to leaf death if untreated, potentially affecting the plant's growth and blooming.
 detail
Flower wilting
Flower wilting is a common issue affecting Cymbidium orchid orchids, characterized by drooping and discoloration of the flowers. Lack of water, overwatering, unsuitable environmental conditions, or pathogens can lead to this condition, causing severe to moderate setback in the growth cycle and bloom duration of the plant.
 detail
Root wrinkling
Root wrinkling is a harmful disease affecting Cymbidium orchid, causing the roots to wrinkle, shrivel, and turn brown. It decreases the plant's growth rate, reduces flowering, and can ultimately lead to plant death if left untreated.
 detail
Aerial root
Aerial root is a physiological phenomenon, not a disease, affecting Cymbidium orchid. In response to high humidity, the plant produces roots above the soil. Although unusual, it does not harm the plant and can contribute to nutrient absorption and growth if properly managed.
