There are two types of cherries: Morelia, with colored juice and pulp, and amoreli whose pulp and juice are not painted.Great tasty and useful berries for everybody, well, except that you already very high acidity of the stomach, then little by little little by little, but still can eat it and you.
cause of poor fruiting may be the lack of a suitable pollinator for grafted forms stone fruits, single planting, early autumn frost that kills have not yet matured flower buds.And they ripen in stone only to the late autumn.Or, on the contrary, late spring frosts, when the plants have opened flowers.Sometimes spring frosts pass, when the plants have formed young ovary, then will be reset because the young ovaries as vulnerable as the flowers open.However
reset ovaries is not only because of the drought during the growth of the ovaries or late spring frosts, but also from a lack of potassium in the soil, and calcium, necessary for bone building plants.In addition, cherry leaf spot and monilia also cause prem
Ha south-west of Leningrad region grow and bear fruit varietal cherry and plum.Of the early varieties of zoned: Amorel Nikiforov Shpanka Shimskaya.Of medium ripening - Vladimir, Gorky, Asterisk, Ruby, Rainbow, but from late - Lubsko, Korostynskaya, Summer Lightning, Zhukovsky.
Cherries and especially plums we - plant problem.Firstly, they are usually grafted.They need pollinators.A suitable pair of plants is very difficult to find.And to be honest, often sellers wishful thinking, and you will realize that is not bought the commodity when the plants begin to bear fruit in 4-5 years after planting.
samoplodnye There are varieties of cherries and plums.As a rule, it is the variety of national selection, so you should buy them.In addition, these non-grafted cherry.There are cultivars of plums and cherries samoplodnye, but it does not mean that you can plant a plum or a cherry.The harvest will be meager as well as the absence of the right pollinators.Planting should be in any case not less than two samoplodnye plums and cherries are not less than 2-3.
From samoplodnye cherries the most suitable for the Northwest Cherries are steppe and sand cherries, which grow in the form of bushes.Do not allow too many stems growing out of the ground in a bush.The most expedient to them to have 5-6 pieces.The easiest way to care for them.
There is one more interesting cherry - Prunus tomentosa.This is also the Northwest plant problematic due to the fact that he felt cherries in winter thaw easily freezes the root collar, and as this cherry is not renewed root shoots, the plant often dies.Fix this disadvantage can be, if not non-grafted plant to plant and inculcate cutting Prunus tomentosa on trunks, with a minimum height of 40-50 cm, cherry steppe or thorns.This cherry is attractive because it bears fruit in the Northwest, with abundant and annually, is not subject to the classic diseases of stone fruits - cherry leaf spot and moniliosis, almost no damage by pests.In addition, the plant is very elegant - a lush bush with leaves of blue-gray color, covered with soft down.

Features cherry cultivation
Pruning Pruning cherry - mandatory event.Normal growth of cherry branches -. 30-40 cm The fact that the stone fruit buds and fruit growth.From growth growing leaves and shoots.If the gains this year, small (less than 20-25 cm), then they have only one kidney rostovaja at the top of this thread.The remaining kidney - fruit, they live one to two years, depending on whether the variety of cherry fruits on an annual or biennial wood.Accordingly, twigs and fruit live a year or two, and then die off, and the branch is laid bare.And only at the end of the branches have few leaves.Gradually cherry plant turns into a whisk.
Small increase indicates poor care - lack of moisture and nutrition, poor protection from diseases and pests.Help the plant, and it will restore normal growth, which should be about 40 cm. Branches eventually have to cut with bared barrel to which such branches are attached, to shorten them does not make sense, because you cut only the growth bud and naked branch continue to growwill not be.When bad
annual increment plant should be sprayed with a couple of times over the summer preparation "Ferovit" reinforcing growth of all the shoots, and feed microbial drug "Ekstrasol" in accordance with the attached instructions.
branches with large growth (50-60 cm) should be shortened to the required 40 cm. Branches, with a growth (or more), as a rule, are laid and growth (vegetative) buds from which the formation of new shoots and leaves.And on the long shoots and fruit buds are laid, of which the flowers are formed, and then the fruit, and only the apical bud - Rostov.
After fruiting, fruit buds will die, but the branch continues to fruition as she appeared side branches, which again laid as the fruit and vegetative buds with gains of about 40 cm.
Cherry does not like stagnantwater.In principle, as well as apricot, it is drought resistant, but in the dry spring and summer watering is still needed.Watering should be on the perimeter of the crown plants, in the evening, 4-6 buckets subtree.
Fertilizing in the spring - ash on the liter jar, on moist soil, on the perimeter of the crown, 1 tbsp.spoon of urea and 2 tbsp.spoons chlorine-free potassium (potassium chloride feeding at fold leaves) per 10 liters of water (at least 3-4 buckets per plant).You can replace the potassium nitrate (2 tbsp. Spoons).During the intensive growth of the ovaries should be sprayed on the leaves with a solution of trace elements.In addition, we need another liter of ash bank for bone building.
In mid-August - 2 tbsp.tablespoons of double granulated superphosphate and 1 tbsp.potassium tablespoon per 10 liters of water (m 'it 4 buckets) and again liter ash bank.Liter jar of ash can replace 1 cup of dolomite.
late autumn, after the leaves reset, you can make a couple of buckets of water the organic matter or faeces, as well as apricot.
multiplies own-rooted cherry easiest root shoots, it is only necessary to know that growth should be taken no closer than 1.5 m from the trunk, otherwise you deprive a large part of the plant root system.Obkopayte carefully, not buried in the ground more than 20 cm, root suckers.When you find the root of the mother plant, in which it grows, and cut off its 20-30 cm from the son (not to take away from the parent plant roots).Then try to find the roots around his son and gently dig them.Now it is possible to land on the prepared place in advance.If you save the maximum root system, then the offspring will bloom the following year.Of course, graft cherries do not multiply, because they are grafted on the wildings.Own-rooted cherry and can be propagated by seeds (without pulp), which are sown immediately after harvest.
Excess shoots should be regularly cut to ground level.In own-rooted cherry growing in the form of shrubs, it is necessary from time to time to keep a strong substitution escape, cutting outdated which stopped fruiting.
to shoots was less cherries should not be at planting bury into the soil.
Pests and diseases
most pernicious pest of cherries - this aphid.If you are going to spray spring cocktail, the recipe of which was given in the section on the protection of the garden, at the time of turning leaves, it will not be.Then - fly cherry, hawthorn and cherry moth, sawflies, leaf roller, brant, moth.Regular spraying of plants (once a month) "Healthy garden" save the trees from pests.When a large number of them to be added to the solution of "healthy garden" "Fptoverm".
From the most dangerous diseases monilia and cherry leaf spot.Moniliosis stone fruits are usually manifested in the cold rainy weather in the spring: a sudden overnight leaves turn brown, as if they were scalded with boiling water, and the branches were narrowed, as it were.But usually in early summer on the shrunken branches from dormant buds again unfolding leaves that turn yellow and fall off already in late July and early August.Cherry leaf spot appears in the middle of the summer, causing premature yellowing and leaf fall.In these diseases, yields fall sharply, the berries burst, covered with brown spots, become malosedobnymi.
Typically, in order to save their trees recommend spraying copper-containing drugs.But after such a spray can not be used in writing the fruits and berries for 3 weeks.It is best to use spring cocktail at the time of turning leaves and then every 10-15 days, spray the plants through the leaves "Cubic Zirconia" (4 drops per 1 liter of water).If the increments are small, then add a solution of 2 drops further and "Ferovita".These measures are also suitable for other diseases of stone fruit.
