Flapjack plants, also known as Kalanchoe luciae, are popular succulent houseplants that are easy to grow and care for. However, like all plants, they can experience problems such as yellowing leaves. In this article, we will explore the reasons why flapjack plant leaves turn yellow and what you can do to prevent and fix this issue.

Overwatering

Overwatering is one of the most common causes of yellowing leaves in flapjack plants. These plants are native to arid regions and are adapted to survive in dry conditions. When they are overwatered, their roots become waterlogged, and they cannot absorb nutrients properly. This leads to a lack of chlorophyll in the leaves, causing them to turn yellow.

To prevent overwatering, make sure you allow the soil to dry out completely between waterings. Also, ensure that your pot has proper drainage to prevent water from accumulating at the bottom.

Underwatering

While overwatering can cause yellowing leaves, so can underwatering. When a flapjack plant is not watered enough, its leaves will start to wilt and turn yellow. This is because the plant is unable to photosynthesize properly due to a lack of water.

To avoid underwatering, make sure you water your plant regularly but not excessively. Check the soil moisture level regularly by sticking your finger into the soil up to your knuckle. If it feels dry, it’s time to water.

Lack of Light

Flapjack plants require bright light to thrive. If they are not getting enough light, their leaves will start to fade and turn yellow. This is because the plant cannot produce enough chlorophyll without sufficient light.

To ensure your flapjack plant is getting enough light, place it near a bright window that receives plenty of sunlight. If you live in a region with less natural light, consider using artificial grow lights to supplement the light.

Nutrient Deficiency

Yellowing leaves can also be a sign of nutrient deficiency in your flapjack plant. If your plant is not getting enough nutrients such as nitrogen, iron, or magnesium, its leaves will start to turn yellow.

To prevent nutrient deficiency, make sure you are using a well-balanced fertilizer and following the instructions on the label. Also, ensure that your plant is planted in nutrient-rich soil.

Pests

In some cases, yellowing leaves can be a sign of pest infestation. Flapjack plants are susceptible to mealybugs, spider mites, and scale insects. These pests feed on the sap of the plant, causing damage and yellowing of leaves.

To prevent pest infestations, regularly inspect your plant for any signs of pests. If you do find pests, treat them with an insecticidal soap or neem oil.

FAQ

Can I save my flapjack plant if its leaves have already turned yellow?

Yes. If caught early enough, you can save your flapjack plant by addressing the underlying issue such as overwatering or nutrient deficiency. Remove any dead or yellow leaves and give your plant proper care.

Can I propagate my flapjack plant from yellow leaves?

No. Yellow leaves indicate that the plant is not healthy and may not produce viable offspring. It’s best to propagate from healthy leaves.

Can I use tap water to water my flapjack plant?

Yes, but it’s recommended that you let the water sit out overnight to allow chlorine to evaporate. Flapjack plants prefer slightly acidic soil, so if your tap water is hard or alkaline, consider using rainwater or distilled water instead.

In conclusion, yellowing leaves in flapjack plants can be caused by various factors such as overwatering, underwatering, lack of light, nutrient deficiency, and pest infestation. By understanding these causes and taking the necessary steps to prevent and fix them, you can ensure that your flapjack plant stays healthy and vibrant.
