Why yellow currant leaves

Yellow currant leavesDid you notice the yellow leaves on the currant bush? It is not necessary to leave this fact without attention, since it can be disastrous for your plant. Why do the currant leaves turn yellow on the bushes? This is most often affected by two factors.

  1. Dryness of soil. Therefore, in an overly hot summer it is necessary to water and feed the bush of the currant. Only then it will give a rich harvest.
  2. Pests, and to be more precise - gallic aphids. This insect is most often found on the bushes of red and white currant, but occasionally the black-bush bushes also become infected. Consider how to deal with this pest to protect the currant.

Gallic aphid

Gall midge is a small insect of dull yellow color, giving for a season up to 7 generations. You can see these insects on the underside of the leaf, where they settle in entire colonies.

The currant leaves turn yellow due to the fact that aphids, piercing the vessels of the leaf, draws nutritious juice from them. As a result, the leaf blade is deformed and covered with blisters of reddish or yellowish color, which after a while darken, and the leaves turn yellow and prematurely fall off. The berries on the infected bush are small or do not appear at all. Young shoots slow down growth, the plant is weakened. If you do not start fighting with these insects, then very soon they will populate the entire plantation of currants.

How to fight if the currant leaves turn yellow

During the harvesting period, the plant should not be treated. You can only remove severely damaged leaves and cut off young deformed shoots.

Immediately after harvesting, the infected bush should be fed, cut damaged branches and treated with a special solution from leaf-sucking insects (aphids). Handle carefully enough both the lower and upper sides of the leaves.

In autumn it is necessary to re-process the bush. This is due to the fact that the aphids feed on the currant only until the middle of summer, and then flies to grassy plants. On them, it feeds and reproduces, and in autumn the females return to the currant bushes and lay eggs for the winter. Therefore, you should be extremely careful and do not miss this moment.

In case of severe infection in the summer, it is necessary to repeat the treatment again in the spring until the kidneys bloom. This will help destroy all the aphid eggs that survived the cold. If the leaves of the currant turn yellow in connection with the invasion of aphids, then these measures will help.

Folk remedies

For the exile of aphids it is useful to plant tomatoes in the intervals between currant bushes. Phytoncides, which are distinguished by a tomato planta, are unpleasant for all species of aphids. You can choose low grades for open ground. Also, with minimal infection, you can use chamomile, yarrow, tobacco or makhorka. Carefully should also process the bottom of the sheet.
