Curling leaves on houseplants may be caused by a number of factors, including poor maintenance and the presence of pest infestations. When you buy a new plant, be sure to read the tag thoroughly and assess whether or not you can offer the appropriate conditions for it. Keep the tag as a point of reference in the event that the plant does not survive. Curling of the leaves is one of the many issues that may be avoided by providing the plant with the proper environment and paying attention to its requirements.
If the tips of older leaves begin to curl under, this might be a sign that the plant is receiving an excessive amount of light. More information will be provided by younger leaves. When new leaves are exposed to an excessive amount of light, they may shrink more than typical and develop brown borders. You might try putting the plant farther away from the window, or you could hang a sheer curtain to diffuse the light coming in. Many houseplants that originate from tropical regions thrive when exposed to direct or indirect sunshine. These plants thrive well at a spot next to a window, but it is important to make sure that the foliage is never exposed to the sun’s rays directly.
When the leaves of a plant begin to yellow and curl under, it is possible that the plant is experiencing heat stress. Under no circumstances should plants be placed close to radiators or heat registers. When intense sunshine from the south is cast directly onto a window pane, the pane itself will emit a significant amount of heat. Remember to water your plants and leave the air conditioner on a slightly lower setting if you intend on going away during the sweltering months of summer.
Too Much Water
If the lower leaves begin to curl under, this indicates that the plant is receiving an excessive amount of water. The ground ought never to be saturated with water. Between waterings, the top inch of soil should be allowed to dry out completely. After each watering, the plant should get as much water as the soil can handle. The pot’s bottom should have drainage holes in it, and any surplus water should be able to flow freely through those holes. In the event that it does not, check to see that the holes have not been obstructed. After around twenty to thirty minutes, you should remember to empty the saucer that is sitting beneath the plant. Root rot may be caused by both overwatering and allowing the plant to remain in a saucer of water for an extended period of time.
Aphids are small insects that have an oval form and feed on the liquids that are produced by houseplant leaf. The leaves twist and curl as a result of the insects’ consumption of the liquid. The undersides of leaves are a common location for the colonies of aphids that are found on plants. You may get rid of them by snipping off any leaves that are highly affected and then spraying the plant with water, which will help to expel the insects. They can be eliminated in one treatment with insecticidal soap, but it can need more than one application to get rid of them altogether. It is in your best interest to isolate the plant from any other plants until you are certain that the aphid population has been brought under control.
