Blackberry – a shrub or a liana with a rapidly developing aerial part. On an industrial scale, it is grown in the US. In Russia it was widely used only in private subsidiary farms and in suburban areas. There are more than 300 varieties of this culture. They are divided into two subspecies: clustered blackberries and curly varieties.
Bush plants can be grown without trellis, and a curling blackberry for good development needs support. Care for the bush blackberry and plant-liana in the summer is different, but the preparation for the winter is no different.
The formation of blackberry fruit spends a lot of nutrients. In order to get a good harvest for the next year, you need to spend the autumn fertilizing of the plant. You can use complex mineral fertilizers for berry crops without nitrogen.
If you are a supporter of organic farming, use for fertilizing:
- wood ash;
- rotten cow dung or compost;
- crushed bark of pine or any other coniferous tree.
Blackberry compost with “Californian” worms. Having fallen under a bush, they will continue to process compost in humus, and the blackberry will receive even more nutrients.
The increased content of potassium and phosphorus will help the plant to form a large number of fruits for the next season.
When preparing the blackberry bush for the winter, remove the shoots from which the harvest was harvested. Leave only young growth.
Developed bush blackberry must be properly formed. The central shoot of the plant is cut to a height of 2 m, the branches of the second order are shortened to 80 cm, the third-order shoots are trimmed, leaving only 30 cm of branch.
All the shoots are wrapped in agrofiber and laid to the ground. Branches of the plant pinned to the ground and mulched. Before mulching it is necessary to carry out water-charging irrigation.
Autumn water-charging irrigation
Blackberries are very fond of moisture, so they need regular watering. In order for the bush to form a large number of fruits for the next year, they carry out water-charging irrigation. Each plant consumes 10 liters of water.
Mulching of a plant
As mulch it is possible to use coniferous lapnik, peat or leaves of fruit trees. Blackberry foliage for mulching is best not to use, since it can have a blackberry mite. Fallen blackberry leaves should be removed from under the bush, they are used for mulching other crops.
