History of

The variety "Blue Plum" was bred relatively recently. is he was formed as a result of the crossing of the old domestic variety "Skorospelka" with the Western European variety "Renklod Ullensa".

Landing rules

The most suitable time for planting seedlings is early spring. It is necessary to plant a tree before the snow completely melts, even before bud break. For landing fit well lit areas. All varieties of plums for successful growth require the following conditions:

  • abundance of light;
  • wind protection;
  • sufficient watering;
  • regular pruning;
  • the presence of nearby different varieties of plums.

For a grade the loamy soil, with the lowered level of acidity will be idealwhich would contain enough calcium. Groundwater should be below the two-meter level.

Preparing the pit for plum planting

The soil for planting will need to prepare in the fall. It must be thoroughly dig and zazvestkovat. In the same period, landing pits are being prepared. Landing pit dimensions: 60 cm - depth, 80 cm - diameter. About half a kilogram of wood ash is laid on the bottom. Then the pit is filled with soil mixed with two buckets of compost, you can also add a pound of superphosphate.

The peg is deepened into the hole and the seedling is immersed, gradually sprinkling it with soil and tamping it down. Above the ground, at a level of about 4 cm, the root neck is left. The tree is loosely fixed to the peg, around it form a watering hole. Having planted a sapling, it is poured abundantly with water. The soil around the trunk must be dried with dry peat.

In order for the tree to stick well, you can use a growth stimulator, for this, three tablets are diluted in a bucket of water.

Plant Care

One year after planting, you will need to feed the tree. This procedure is carried out twice: at the beginning of June and at the end of the month. Nitrogen fertilizers are taken as top dressing..

Top dressing plums

The next feeding should be scheduled for the third and fourth year. It is carried out three times in one season:

  1. May feeding: a solution of urea - 3 tbsp. on the bucket.
  2. June feeding: Nitrophoska - 3 tbsp. on the bucket.
  3. August feeding: superphosphate and potassium sulfate - in the same volumes.

For one plant you need to prepare 20 liters of fertilizer.

In the fifth year, additional feeding is carried out three times:

  • before flowering;
  • during fruit ripening;
  • after picking berries.

You will also need to regularly carry out the following procedures:

  • weeding;
  • watering;
  • loosening;
  • mulching.
Top dressing plums: mulching

Primary pruning is done immediately after landing. As a result, no more than ten main branches should remain. This will be the base of the plum crown.

During the pruning procedure of the “Blue Plum”, it is important not to allow the branches to grow randomly, thickening the crown should also be avoided.

In the spring make pruning of patients, frozen, damaged branches. Remove excess shoots and root shoots. Gains need to be shortened slightly.
