What not to fertilize raspberries with: wilted in one day
To grow delicious and large raspberries, you should follow the basic rules of fertilization and pest control. Preventive spraying begins in April-May. You can make a Bordeaux mixture solution by mixing 10 liters of water and 300 g of the mixture.
It is important to remember the need for timely pruning. This is especially true for remontant varieties that can bear fruit several times a year. If you neglect the rules of care, this property can be lost, and the bush will produce berries only once a season. According to experts, some fertilizers should definitely not be used to fertilize raspberries, or they will wither in one day. Read more about this in the OBOZREVATEL article.
The first rule of raspberry care is that it is better not to mix fertilizers. Alternatively, you can first feed the bushes with manure, and after 2 weeks add wood ash.
Experts do not recommend applying large amounts of nitrogen fertilizers, especially in the fall. In winter, young shoots can quickly die. In general, nitrogen fertilizers accelerate the growth of shoots but stop the growth of berries.
Nitrogen fertilizers should not be applied in the spring, as they contribute to an increase in soil acidity. High levels of acidity are not suitable for raspberry bushes.
Chlorine is another prohibited element that should not be used in fertilizers. Raspberries do not like or tolerate this substance.
You can fertilize the bushes with humus no more than once a month because pests love this fertilizer. For 1 square meter, you need to take 1 bucket of humus and sprinkle it with soil.
This fertilizer is considered ideal for raspberries, especially poultry manure. The solution should be infused for 5 days by putting the manure on the bottom of the bucket and pouring water over it in a 1:20 ratio.
Raspberries love fertilizer made from fresh weeds and nettles. Fill the bucket a quarter full of chopped herbs, cover the mixture with water, and leave it for 10 days.
Minerals contained in wood ash are very useful for raspberries. This is the simplest fertilizer; ash is applied in its pure form under the bushes. Alternatively, you can prepare a mixture: Infuse 600 g of ash per 10 liters of water for exactly one day and water it under the roots. For 1 bush, 2 liters of solution are enough.
