How to grow sweet raspberries: what to fertilize in the spring and what to give up

Raspberries are a delicious and nutritious berry, a real storehouse of useful vitamins and minerals. At first glance, it seems to be a fairly unpretentious crop, but often instead of a large and juicy harvest, you have to pick small sour berries.

Irregular watering and untimely fertilization are the main reasons for a poor harvest. How to grow sweet raspberries and what to fertilize them with – read in the OBOZ.UA article.

What fertilizer is dangerous for raspberries

You can find a lot of fertilizing tips online, and not all of them are effective and safe. For example, it is better not to use fertilizers that contain chlorine – this trace element negatively affects the condition of the bushes. Raspberries can face a very dangerous disease – chlorosis.

How to feed raspberries

A lack of nutrients can cause the berries to turn sour. However, experienced gardeners note that proper fertilization will positively affect the taste of raspberries.

During the off-season, the bushes need nitrogen. One of the following fertilizers can be applied:

• urea;

• nitroammophoska;
• ammonium nitrate;
• cow manure.

During the budding period, the bushes need phosphorus, but you should also pay attention to other trace elements. Diammophoska will have a good effect on the crop.

During flowering, it is worth replenishing the potassium and phosphorus deficit in the soil with appropriate fertilizers. Alternatively, you can use potassium nitrate and superphosphate.

It is important to remember the need for timely pruning. This is especially important for remontant varieties that can bear fruit several times a year.
