The use of organic and mineral fertilizers for blackberries
Blackberries require constant care. This culture bears fruit in the second year after planting. The thornless blackberry varieties tolerate frosts worse, but such bushes are easier to care for. Blackberries are harvested in the summer, depending on the variety, from mid-July to late August. To get the maximum yield, blackberries need to be fertilized. The shrub responds well to organic and mineral fertilizing. Young seedlings of fruit shrubs are mulched and fertilized with siderates. Mustard and barley are used as green fertilizers. They are sown in summer and mowed down during flowering. Siderata additionally perform the function of mulching. The blackberries covered by them will winter better, and in the spring, after rotting siderates, the shrub will receive additional nutrients. Besides mulching, blackberries love and organic fertilizers.
Preparation of organic fertilizers
For blackberries, you need to prepare a solution of organic fertilizers. You can feed the blackberry bush with a solution cow dung, but horse dung tincture works best. Horse manure can be purchased at gardening stores. It is diluted in hot water and left to infuse for exactly 7 days. Add 250 g of manure per liter of water. Such a tincture is watered with blackberry bushes in the fall.
In the summer, the concentration of the infusion can be reduced. One liter of this organic fertilizer is dissolved in 10 liters of water. The nitrogen content in this fertilizer is sufficient to stimulate the formation of new shoots, but with an excess of nitrogen, the fruiting of blackberries will decrease.
If you feed the blackberry bushes with chicken manure, do not overdo it, otherwise there is a risk of burning the roots of the young bush.
Near each bush it is necessary to make a small hole and pour a solution of organic fertilizers into it. This will allow the solution to reach the roots faster.
Fertilizing with mineral fertilizers
As mineral fertilizers you can use potassium salt and urea... In addition, it is worth paying attention to complex mineral fertilizers. For blackberries, you need to use universal fertilizers or fertilizers for fruit crops. It is not necessary to treat blackberries from pests and diseases with insecticides and fungicides. Pests do not infect blackberries, and the shoots of this plant have natural immunity to fungal diseases.
