Fruiting begins in the second year of escape. Thornfrey blackberry leaves are large, double-serrated, slightly pubescent, dark green in color.

At this time, the berries are still sour and practically do not smell, but they retain their shape perfectly.

It is usually enough to pour Thornfrey blackberries once a week up to 20 liters of water under the bush.

To increase productivity, experts advise forming a bush by pruning the branches that ploskonos this year

Others, on the contrary, believe that productivity is better increased by increasing the volume of the bush. However, as practice shows, in this matter it is necessary to take into account the factors of a particular landing:

  • area of ​​the plot allotted for blackberries;
  • number of bushes;
  • personal preferences.

In order to form a fan bush, the fruiting branches of the blackberry are woven, laying one on top of the other. At the same time, new shoots are left to grow freely, only orienting them in the right direction.

If the method of growing Thornfrey blackberries with short cropping is chosen, then when the shoot reaches the desired length, it is cut with a pruner. This stimulates the growth of the lateral stems, which are also pruned later.

In any case, experienced gardeners recommend cutting the shoots that bear fruit this year. This significantly increases productivity.

Thornfrey Blackberry Reviews

Despite the fact that the Blackberry Thornfrey variety was bred more than half a century ago, it is still quite competitive and very popular. Most of the farmers leave positive feedback about him.

The variety differs from other blackberry varieties by the absence of thorns, unpretentiousness and very high productivity, large berry size. It turns out that blackberries are more healthy than raspberries! The cultivar was advised to me, a beginner gardener, as an "unkillable one." A sapling with a closed root system, planted in early summer, by the fall gave 6 five-meter semi-rigid shoots, which we tied to a wire trellis, lifting it above the ground. They removed it for the winter, turned it into a wide ring, laid it on the boards and covered it. In spring, the overwintered lashes were raised again to the trellis - blossomed along the entire length of the shoots with beautiful pink tassels. There were a lot of flowers. The resulting berry brushes did not keep up at the same time, we had to make a selective collection. Ripe berries are very sweet, fragrant, slightly tart and can easily be separated from the stem, transportable, the size of a phalanx of a finger. If you give it to ripen, it becomes watery and sprawls ... Rip from the beginning of August to frosts ... From the berries you get very tasty jelly, liquor, stewed fruit ... Over the summer new shoots grow that we leave for the winter, and cut off the offspring. And that’s it. Wonderful berry and a wonderful variety.

I want to note that I received the crop without much care (all the forces were thrown into the vineyard). For the winter they covered with straw - the blackberry did not freeze, but was decently decayed by mice. This year they covered it with polypropylene bags on frames and put poison in plastic bottles, spring will come - we'll see. Watering - once a month (in such a heat!), Aisles tinned (mowed once a month), trellis - thread, stretched between meter pegs. Of course, I did not get a huge harvest and very large berries, but it was enough to eat and preserve. Naturally, with good care, the harvest will be larger and the berry is larger and sweeter, but those with a time limit or a remote land will also not be left without a harvest.
