Before starting treatment, you need to thoroughly clean the bush from dry and diseased branches, affected leaves and flower stalks to stop the spread of infection throughout the bush.
It is essential to change the top layer of soil around the bush.
Next, the treatment with a special agent should be carried out from the top of the plant. It is better to do this on a dry and windless day.
The mixture against powdery mildew is easy to prepare.
You need to take 4 tablespoons of soda and 2 tablespoons of liquid soap. All this needs to be mixed in 10 liters of clean water. You need to treat the gooseberry with this product once a week.
If the bush is affected by powdery mildew and aphids, you can prepare a solution based on soda and iodine. To do this, dilute 2 tbsp. soda in 10 liters of water and add 2 tbsp. liquid soap or any detergent, and also add at least 10 ml of iodine.
As experienced gardeners note, the first treatment should be done before the sap starts to flow. If necessary, the procedure can be repeated at the beginning of the blossoming of flowers.
