What to do about crabapple leaf rust? What's wrong with dry leaves?

1. What to do about leaf rust

Rust disease is more common in various types of crabapples. When the disease is more serious, various spots will appear densely on the leaves, causing the leaves to begin to turn yellow and even fall off. Avoid planting them together with pine and cypress trees, which will reduce the chance of disease. If there are pine and cypress trees nearby, use pesticides to prevent and control the disease. If the disease has already begun, you can spray 1:200 Bordeaux liquid on it for treatment in the early stages, which can effectively control its occurrence and spread.

2. What is the dry leaf?

Dry leaves are very common and there are many reasons for this, mainly as follows:

1. Too much water: This plant is very afraid of waterlogging. If you don’t control the degree of watering and apply water too much when the soil in the pot does not need it, it will cause the roots to rot and the leaves to dry out. You must control yourself at ordinary times and don’t add anything arbitrarily.

2. Too much nutrients: Nutrients support the growth of plants. Applying too much fertilizer will cause the roots to accumulate and rot, and the leaves will be unable to absorb it.
