There are more than 125 species of plants in the Kalancho genus. But the most common varieties found in homes include Kalanchoe blossfeldiana, Kalanchoe daigremontiana, and Kalanchoe beharensis. Each variety has distinct features. For example, flower color, leaf shape and size.
Kalanchoe has air-purifying properties which can improve the indoor air quality. Some species of Kalanchoe have medicinal properties. For example, you can use kalanchoe pinnate leaves to make tea. Kalanchoe can alleviate respiratory issues and digestive problems.
Improper lighting is a common culprit for kalanchoe leaves turning brown. These plants require bright, indirect light to thrive. Don't place kalanchoe plants in direct sunlight or low-light conditions. The leaves will become scorched or discolored.
Kalanchoe plants prefer consistent temperatures. Temperature fluctuations can affect the kalanchoe's health. Sudden changes in temperature can cause stress and lead to kalanchoe brown spots on leaves. Low humidity levels can also cause their leaves to dry out and turn brown at the edges.
Overwatering is one of the common mistakes when caring for kalanchoe plants. Root rot occurs when the roots are constantly saturated. The roots can't get oxygen. The leaves will turn brown and wilt.
On the other hand, underwatering can also lead to brown leaves on kalanchoe plants. The leaves will start to wilt and eventually turn brown without enough water. Because the plant can't absorb enough moisture and nutrients to maintain healthy green leaves.
Mealybugs: These small insects feed on the sap of kalanchoe leaves. This causes the leaves to wilt and turn brown.
Aphids: These tiny insects also feed on the sap of kalanchoe. They can damage the leaves if left untreated.
Scale Insects: These pests suck out the plant's nutrients. This results in kalanchoe plant leaves turning brown.
Powdery Mildew: This fungal disease appears as a white powdery substance on the leaves. Powdery mildew on kalanchoe can cause the leaves to turn brown and eventually die.
Root Rot: This fungal disease is caused by overwatering and can result in brown, mushy leaves.
Kalanchoe leaf spot: This is a fungal disease caused by the pathogen Cercospora kalanchoae. It initially manifests as small, water-soaked lesions on the leaves. Kalanchoe leaves eventually turn into brown or grayish spots.
The main symptom is kalanchoe leaves turning brown. Other signs include wilting, yellowing, curling. Identify these symptoms early on. You should take appropriate measures to prevent damage.
Offer Suitable Lighting Conditions: Kalanchoe plants require bright, indirect light. Make sure to place them near a window with sheer curtains or in a location that receives filtered light.
Maintain an Optimal Temperature Range: These plants thrive in temperatures between 60-85°F. Avoid exposing them to extreme heat or cold. Anything below or above this range can cause stress to the plant, resulting in brown leaves.
Managing Humidity: These tropical plants thrive in moderate to high humidity of between 75%-85%. So you may need to increase the moisture levels around your plant if you live in a dry area. You can mist the leaves regularly or place a tray of water near the plant to increase humidity.
Pruning: Remove any dead or damaged leaves as soon as you notice them. Because they can spread disease to other parts of the plant. Regularly pruning can also help promote new growth and keep the plant looking full and healthy.
Watering Schedule and Technique: When watering your kalanchoe plant, consistency is key. These plants thrive in well-draining soil and do not like to sit in waterlogged soil. It is recommended to water your kalanchoe once a week. Make sure the top inch of soil is dry before watering again.
Avoid getting water on the leaves when watering. Instead, direct the water towards the base of the plant. Allow it to soak into the soil. Additionally, using room temperature water is preferred. Because cold water can shock the plant.
Well-draining Soil: Kalanchoe plants prefer well-draining soil. This allows for proper air circulation around the roots and prevents kalanchoe root rot. To ensure good drainage, you can mix organic materials such as perlite or sand into your potting soil.
Fertilizing: Kalanchoe plants do not require frequent feeding. During the growing season, you can apply a balanced fertilizer every month. For example, an NPK ratio of 10-10-10. Avoid over-fertilizing because the salt will build-up in the soil.
Repotting: If kalanchoe leaves still turn brown with proper watering and fertilizing, it may be time to repot it. The soil can become compacted and depleted of nutrients over time. Repotting your kalanchoe in fresh potting soil can help rejuvenate it and promote healthy leaf growth.
Treatment Options: One option is to use an insecticidal soap or horticultural oil. You can spray directly on the affected areas of the plant. You can also introduce beneficial insects. For example, ladybugs or lacewings.
Preventing Diseases: To prevent kalanchoe plant diseases, water your plant only when the soil is dry. Avoid getting water on the leaves. Provide adequate air circulation around the plant.
Treatment for Diseases: If your kalanchoe plant does develop a disease, it is important to act quickly. Remove any affected leaves or parts of the plant. Dispose of them properly. You can use a specifically designed fungicide to treat the disease.
