The harvest you will be able to collect depends on how you care for raspberries from spring to autumn.
Experienced gardeners do not miss feeding raspberries in April. This is one of the most important things to do in the raspberry patch in spring.
In April, nitrogen fertilizer is applied. Thus, the bushes can be fed with ammonium nitrate or given urea. In the first case, the application rate is 30-40 g per 1 square meter.
You can also use a solution: 30 g of ammonium nitrate per 10 liters of water. Raspberries are watered at the root.
In addition, before the buds open, they are treated against diseases. For this, they use 3% Bordeaux mixture.
In the last month of spring, potassium-phosphorus fertilizers are added. For example, wood ash - 1 glass per 10 liters of water. The resulting solution is added under the root. Ash can be added in dry form.
Instead of ash, potassium magnesium sulfate is used - 30 g per 1 square meter. It is supplemented with superphosphate - 25 g.
