Formed bushes absorb nutrients better, hibernate, correctly distribute the load, form more ovaries next year.

Training

Preparatory stage - pinching the tops... Blackberry whips are more than 5 m long. The tops gradually lean to the ground and quickly take root. Without proper attention, plantings become impenetrable thickets.

Experienced gardeners recommend shortening and tying branches in a timely manner... Pinching young shoots helps stimulate branching. Healthy branches will form until autumn, and next summer each of them will produce a large number of berries.

Some recommendations:

  • pinch the tops at a comfortable height;
  • blackberries are tied up horizontally, like grapes;
  • pinch the next shoots so that 4-5 leaves remain on them;
  • lateral branches are left intact.

In central lane and Siberia, it is better not to do a preparatory pinching of a one-year-old blackberry... Branches need time to grow, lay fruit buds, lignify, and the summer in these regions is short.

Advice! A year later, the full pruning procedure begins.

How to properly prune blackberries

Required materials and tools

For work you will need a sharp pruner, gloves, garters... Thorny shoots damage hands, so they take thick cloth gloves.

The secateurs are pretreated in a weak solution of potassium permanganate. Garters are needed to fix the branches to the support.

Step-by-step instruction

Procedure:

  1. Shoots are neatly tied to a support. This will give them access to the right places.
  2. Dry, diseased shoots are removed with pruning shears. Shorten them to the bottom. They do not leave broken, weak branches - they still will not form, they will only interfere.
  3. Root shoots are removed at the same time.
  4. At the end, long shoots are cut off, growing in a chaotic manner.
  5. 4-6 fruiting branches are left on one bush.
  6. In addition, the tops are formed so that the blackberries acquire a compact and well-groomed appearance.

Mistakes to Avoid

Beginners leave stumps after removing shoots... Often they become a haven for blackberry aphids, spider mites, stem gall midges, and various caterpillars. The vital activity of pests leads to the appearance of white spot, rust, didimella, anthracnose.

Another mistake is to break out thick branches with your hands.that cannot be cut with the pruner. In this case, it is better to use a sharp saw. Saw the stems neatly, at right angles. It's good if the lower part of the branch is hidden in the ground.

  • remove all direct shoots that have formed berries in the current year;
  • cut off weak branches, leaving 9-10 of the strongest and healthiest.

If the blackberry belongs to the covering varieties, after pruning it is protected from frost... For this, the vines are wrapped in spunbond and lightly leaned against the ground.

For creeping varieties

This blackberry has flexible, long stems. They grow up to 10 m, so special supports are installed for convenience.

Prune after fruiting, taking into account the following tips:

  • completely remove branches on the right side;
  • 10 strong shoots are left on the left, and the rest are eliminated;
  • make trenches along the bushes;
  • vines are removed from the trellises, placed in ditches, covered with warm material.

For remontant varieties

For studless varieties

These are new varieties with smooth branches. Formed from side shoots.

Features of pruning young and old blackberries

Key recommendations:

  1. Young bushes are shortened by 10-15 cm. In the next season, blackberries will thank them with abundant flowering and fruiting. If most of the stems are cut, the bush will die in winter.
  2. Mature plants require removal of old, broken, diseased, damaged shoots. If they remain, the bush will weaken and become sick.

Often, beginners delay pruning, believing that there is still time before winter. But young bushes, cut shortly before frost, do not have time to get stronger and die in winter.

Care after pruning
