What should I do if the camellia leaves? What is the cause of camellia leaf withering (Figure)

The following information is excerpted from the conversation between Uncle Gardener and Flower Friends. In order to facilitate reading, Uncle Gardener made appropriate additions and deletions. If there is anything wrong, please understand and give feedback.

Don't be stubborn: ask for help. Question: Camellia leaves wither, fall off, and turn black. Maintenance: there is no sun, water spray for a few days, and there is no wind.

This was before. If you look at it every day, you can see its changes (above). Soak in water and prepare the roots and soil to be disinfected together.

There is no soil in the middle, it is all roots. (Above)

Monk Flower: You can't make this pot. The temperature rises in summer, and your basin is too deep to breathe. Those who change shallow clay pots and grow flowers in plastic buckets are hooligans.

Listen to the snow: flowers are raised in plastic buckets. There is little soil below, and the top is so high from the edge of the bucket that it is inevitably not ventilated.

The root system grows so well that it should not cause yellow leaves, dead leaves and night. It's not ventilated, so it's suggested to change the basin, put a basin under it, put something similar to a basin ring on it, put the flowerpot on the basin ring, let it evaporate upward, ventilate up and down, ventilate. When the temperature exceeds 30 degrees in summer, camellia will hibernate, so the wilting of leaves may also be caused by dormancy.

Memories of late summer: I saw this flower friend's camellia was not dormant in summer, but infected by soot bacteria. Remove diseased leaves and spray broad-spectrum fungicides on the leaves, such as 70% thiophanate methyl wettable powder, 75% chlorothalonil wettable powder,1:1:800 times solution, 77% Cody wettable powder or 0.3%-0.5% Bordeaux solution, etc.

After root washing, the taproot is thick, the capillary fibrous root is rich, there is no rotten root, and the root system is very good. It is suggested to use acidic red loam special for camellia, and shallow clay pots with good water permeability (clay pots and clay pots, about 20-25cm in diameter and height) should be placed on the pots. After the flowerpot is put away, water it slowly and keep it in a ventilated and cool place. After watering, be sure to tap the basin to listen to the sound, and then slowly pour the basin and soil. After the pot is cooked, the leaves may continue to fall because of the root system. Bagging can also be used to moisturize, but pay attention to opening the bag every day for ventilation, or don't tie the bag mouth during the day and tie it at night.

Look at my camellia, shallow basin and red loam. It has grown well since it was planted in the pot in June, 5438+February last year, and new leaves have grown in spring. They are outdoors in the west, naturally ventilated, semi-sunny, dry and watered thoroughly ~

Plain life: I also bought a new pot, less than a month. So far, not bad. Camellia needs red soil, which likes low temperature and is not resistant to high temperature. Attention, breeding friends.

Thank you very much for your contributions to this article, such as infatuation, listening to snow, becoming a monk, memories of late summer and plain life!
