Reasons Why Kalanchoe Leaves Turn Yellow or Brown

Problems with watering

Think about whether or not the kalanchoe plant is getting enough water before continuing. It turns out that poor watering accounts for a large percentage of these plants’ most prevalent problems.

For example, kalanchoe plants are particularly delicate and need careful attention when it comes to watering. A constant supply of water will kill them. Many individuals overwater their houseplants because they don’t realize how much water they actually need. There will be various negative effects on the plant as a result of this.

Flowers on a kalanchoe plant may wilt if the plant is neglected. If you continue to overwater the plant, the leaves and stems may rot and become mushy and fragile. You should probably water the plant a little less frequently than recommended because of this problem. It is preferable to water these plants only when they show signs of need.

Leaves that have dried up from a lack of water will ultimately turn brown and fall off the plant. If the plant hasn’t been watered in more than a month, you may notice that its leaves have wrinkled.

Indoors, these plants require watering around once every two to three weeks. Obviously, variables like temperature can affect the outcome. Never adhere to a regular schedule while watering these plants. The best way to tell if plants need watering is to look at the soil.

Touch the top two inches of soil with your fingertips to see if they are dry. The top two inches of soil on your Kalanchoe plant should be watered when they are dry.

Keeping this in mind will make it less likely that the leaves will turn brown or yellow. Obviously, you should also think about a few other things.

Scorching Temperatures

The leaves can quickly turn brown if subjected to scorching temperatures. Because of their preference for strong light, this occurs more frequently than you may imagine. If you want your kalanchoe plants to grow, you must ensure that they receive adequate sunshine. Plants of this kind are notoriously difficult to keep alive in dim conditions.

Ideally, these plants should be placed in a spot where they may receive lots of natural light. But you need to be cautious about where you put the plants.

Giving these plants too much exposure to sunshine can cause them to burn. Kalanchoes are readily scorched by strong, intense sunlight.

These plants benefit most from bright indirect sunshine. This allows them to get the sunshine they need to thrive without endangering the plant’s leaves.

To put it simply, if you leave the plant out in the sun, it will get severely sunburned. Some or all of the plant’s leaves may become dark, and there may be brown stains elsewhere.

Thankfully, this may be avoided entirely with some forward thinking. It’s easy enough to select a position that provides the plant with bright, indirect light.


As a result of pests, the leaves may sometimes become brown or yellow. Plants of the kalanchoe family are susceptible to attack by a number of common pests.

A few common pests to watch out for are spider mites, mealybugs, and scale. Pest infestations can happen at any time, so it’s important to keep a watch on your plant.

The minute size of spider mites makes detection challenging. Seeing them in their natural habitat is uncommon, but you can find their little webs.

It’s possible that you’ll see white webbing on the leaves of the plants or elsewhere. This is undeniable evidence of the presence of spider mites. Because of these pests, it is common for leaves to become yellow and even spotted. Browning and drying out of the leaves is a natural consequence of neglect.

To a comparable extent, mealybugs and scale will be a nuisance. Sticky leaves and black mold might be the results of these bugs’ infestation.

Eventually, the leaves might turn brown and fall off the plant. It’s obvious why addressing pest control concerns promptly is important.

There are several options for exterminating unwanted pests. You might try spraying the plant with water in an effort to wash them away, but if you do so, be sure to dry the plant well afterward.

Insecticidal soap can also be used to treat the plant. As a bonus, this kind of pest control may also help your houseplants stay pest-free for longer.

An insecticide is another option for getting rid of unwanted bugs. Although effective, this is not something you should use inside your house.

Not only is it unnecessary, but it’s also quite unlikely that insecticidal soap would be effective. Moreover, the soap will be gentler on the plants than chemical-based alternatives.


Brown or yellow spots on kalanchoe leaves are an indication of a disease. You should be on the lookout for a few widespread illnesses. Overwatering can lead to rot and other fungal problems for the plant. You are aware that overwatering might kill these plants.

Too much watering might encourage the growth of fungi on the plant. As a result, the plant may succumb to fungal diseases such as root rot.

The leaves of these plants can also become yellow due to bacterial diseases. Both overwatering and overfertilizing can lead to bacterial diseases.

You should be careful not to over-fertilize these plants. If you’re using fertilizer, don’t go overboard; stick to the recommended dosage. Fertilizer should be diluted before usage in several cases. It’s best to limit fertilizer applications.


You now have a good understanding of what factors contribute to the brown or yellowing of the leaves on kalanchoe plants. The list of potential problems to consider is enormous. Overwatering your kalanchoe plant might be the problem. Over-watering will cause these plants to wilt and die.

If you continue to overwater the plant, the leaves may turn brown, get soft, and wilt. The plant can also suffer from being underwater. Drying out the leaves is a sign that the plant isn’t getting enough water. They begin to discolor to a brownish hue and may finally fall off.

Pests can also cause the plant’s leaves to become brown or yellow. Insects, including spider mites, scale, and mealybugs, have been documented as attacking these plants. However, eliminating pests is a simple task. Both water and insecticidal soap can be used to remove them from the plant.

These plants are susceptible to sunburn and should be protected against it. Put them in a room that gets lots of indirect sunlight.

Diseases caused by bacteria and fungi must be avoided as well. It’s important to be mindful of how much water you’re putting into your plants since doing so might increase the likelihood that you’ll encounter problems like these.

Please take whatever measures are necessary to restore the health of the plant. The lessons you’ve learned from this experience can be applied to future kalanchoe care, which will prevent the plant’s death if it was caused by your carelessness.
