Ripening and fruiting

The variety is fast-growing, the first harvest is harvested in 3-4 years. This plum is late in terms of ripening. It bears fruit by mid-September, annually.

After planting a plum sapling on the site, of course, the question of the beginning of the fruiting of the tree always arises. Most varieties of plums begin to bear fruit 4 years after the seedling is planted. However, there are those that differ in an earlier or later period of fruiting. The difference in the beginning of fruiting is determined by the color of the plum. So, purple varieties always begin to bear fruit earlier - by 2-4 years, but yellow varieties differ in later fruiting.

Yield

The collection volumes are high, from each tree it is possible to get up to 90 kg of ripe fruits.

Growing regions

Officially, the variety is not zoned for the Russian Federation. But it is successfully grown almost everywhere, from the Moscow Region to the Central Black Earth Region.

Self-fertility and the need for pollinators

The variety is partially self-fertile. Plums of parental subspecies, as well as Empress, Anna Shpet, Rusch are best suited for him as pollinators.

Growing and care

Bluefree is a plum sensitive to good grooming. Plants are hygrophilous, respond well to feeding. Due to its tendency to thicken, it requires constant thinning and crown formation.

Planting of the plant is carried out in the autumn months in the south, in the north it is better to postpone it until spring. It is important that before the cold weather the plum has time to acclimatize. Seedlings are selected at the age of 1-2 years. The landing pit on the site is prepared in partial shade, but in a well-lit area. This tree does not tolerate extreme heat very well.

The hole is formed to a depth of 0.8 m and in the same diameter range.Excess soil is removed, mixed with organic fertilizers and a mineral complex. Dense soils can be slightly diluted with sand, loosening them. Then the pit is filled with soil substrate by 2/3. The seedling is also soaked, the roots are placed in a humid environment, a growth stimulant can be added to it.

The rest of the planting process is standard. A young tree is set in a hole, sprinkled with the remaining earth. The soil is compacted in the near-stem circle so as to raise the root collar above the edge of the pit, by about 2 cm. The plant is watered with 3 buckets of water, dosed in 10 liters each, allowing it to be absorbed. The center conductor is then cut to a height of about 0.8 m.

For normal development and timely release to fruiting, the plum must be planted at a favorable time, provided with food and water. It is necessary to choose the right seedling, determine the location, prepare the planting pit in advance.
If you wish to get a full harvest in the future, and to renew the tree, the plum is grafted onto crops that are classified as pink. In this case, the plum cuttings are implanted on the mother plant, which will be responsible for further vegetation and nutrition of the scion.
Pruning plums is not easy and very important. If it is not carried out, the number of branches on the tree will be excessive, the crown will become too thick, the fruits will begin to shrink. You can trim plums in spring, summer and fall.
Plum feeding is one of the important stages of fruit crop care. In order to properly and fully feed the plum tree, various types of fertilizers are used. Both mineral and organic options are used. Many of the folk remedies are found to be useful and effective.

Disease and pest resistance

Bluefri plum is not very susceptible to fungal diseases, it is resistant to most pests. The scab is affected, the plant is relatively protected from it, but not completely. Tolerant to shark - smallpox that affects the plum.

Despite the fact that plum is considered more hardy than many fruit trees, it is not immune from diseases. It is attacked by viral, fungal and bacterial infections, and parasitic insects harm it. It is necessary to notice and recognize the signs of plum disease in time. They are easier to deal with and defeat early on. Well, in order to protect the garden tree from such a misfortune in the future, preventive procedures can be carried out.

Reproduction of plums will help save on planting material: you do not have to pay money for a seedling. In addition, this activity is simple and exciting. Plum can be propagated by cuttings, root shoots and layering.

Review overview

According to summer residents, the Bluefri plum has practically no flaws. Experienced gardeners advise not to rush to pick the fruits of this tree. They are left on the branches until mid-October, if climatic conditions permit. These plums are the tastiest. The collected fruits are stored in boxes, frozen, processed, getting delicious prunes or jam.

Minor disadvantages of the variety can be considered a weak drought resistance. And also gardeners are unhappy with the fact that the harvest has to be rationed so that the fruits do not shrink, remain large and juicy. If all the ovaries are preserved, the branches of the tree can simply break off under the mass of the ripening crop.
