Causes of cracked orchid leaves and how to remedy them

Everyone is familiar with orchids. Many people who love growing plants like to keep a few of them at home. They not only have great ornamental value but also have a captivating fragrance, making them deeply loved by everyone. However, orchid cracking also troubles people, and many ask what causes orchids to crack and how to remedy it after cracking. Let's take a look together.

Cracked orchid leaves may be caused by scale insect pests, in which case insecticide should be sprayed promptly. In addition, improper fertilizing during cultivation can also cause leaf cracking, so fertilizer must be applied reasonably and carefully. Plants grown in a closed environment are easily infected, and the leaves will crack and turn yellow, requiring spraying with carbendazim.

Causes of cracked orchid leaves

1. Pest infestation

During cultivation, the plant may be attacked by pests. When grown in spring and summer, it is very susceptible to scale insects, and the leaves will crack, with most of the cracks running lengthwise, requiring the purchase of insecticide for spraying.

2. Fertilizer damage

If too much fertilizer is applied during orchid cultivation, leaf cracking can also occur. In this case, water should be used to irrigate and dilute the fertilizer. In addition, if nutrients are lacking for a long time, cracking can also occur, so fertilizer must be applied reasonably.

3. Caused by pathogens

After an orchid is infected with pathogens, leaf cracking can also occur. In this case, carbendazim should be sprayed to treat the plant, and the severely affected leaves should be pruned. Growing it for a period in a ventilated, bright, indirect-light environment will improve the situation.

4. External damage

During manual cultivation of orchids, a crack may be caused by careless handling, or it may be caused by rain washing over the plant. If the rain is too heavy, cracking can also occur. It is best to place orchids indoors, and when fertilizing, do not drip it onto the leaves, otherwise the leaves will be burned.

2. How to deal with cracked orchid leaves

1. If only the leaves are rotting, remove the rotting leaves, wash them clean in water, and clean up the rotting parts thoroughly.

2. If the root system is found to have rotted, use a blade to cut away the rotting parts, rinse with water, then place in a ventilated, shady spot to dry.

3. Prepare the potting soil; before use, it needs to be exposed to sunlight to serve its purpose. Set the plant upright and replant it, firming the soil so the roots contact the soil. Afterward, pay attention to care methods, control water and fertilizer application, and keep the temperature well controlled.
