Why does Impatiens not grow leaves?

1. Red spider pests

The main target of red spider mites is the leaves of some herbs, especially the tender leaves. If a plant has red spider mites, there will be sporadic spots on the leaves at the beginning, and in severe cases, there will be many white spots, and the leaves will gradually turn grayish white, and then they will slowly dry up and fall off.

2. Powdery mildew

Powdery mildew mainly occurs on the leaves, tender stems and flowers of plants. In the early stage, powdery mildew appears as small irregular yellow-green spots with unclear edges. Then the spots continue to expand, produce white powdery spots, and finally grow into countless black spots.

How to solve the problem that Impatiens does not grow leaves

1. If it is red spider pests, we can use scissors to cut off the diseased branches and leaves. However, if it is already in the late stage and there are many leaves, you can try to spray the leaves with tobacco or pepper soaked in water to see if it can return to normal.

2. If symptoms of powdery mildew are found, the diseased leaves should be removed in time, or even the diseased plants should be pulled out to reduce the source of the disease and prevent the disease from spreading rapidly. If removing the diseased leaves or pulling out the diseased plants cannot completely solve the problem, medication is needed. You can use methyl thiophanate or carbendazim to spray and irrigate the roots. Use it once every 7 to 10 days, and three consecutive uses will solve the problem. You can also spray it once a month for prevention and control.

2. Prune and shape the tree in time, remove diseased branches and leaves, and improve ventilation and light conditions.

3. Starting from early spring, spray lime sulfur mixture or carbendazim preventively once every half a month.

4. After the disease occurs, you can spray 15% oxycarboxin at 800-1000 times, which has a better prevention and control effect.
