Landing rules

In order for the sea buckthorn bush of the Jamovaya variety to take root, it is necessary to properly plant it in a permanent place.

Recommended timing

Planting a Jemovaya bush depends on the presence of an earthen lump on the roots: if it is absent, then sea buckthorn is planted in early spring, as soon as the ground thaws, in late March - early April. For autumn planting, seedlings with a closed root system are suitable; then planting takes place at least a month before the onset of stable frosts.

Choosing a suitable location

When choosing a landing site for Jemova, you need to take into account several important requirements:

Placing sea buckthorn on a site involves planting two seedlings - a male and a female.
The sea buckthorn bush bears fruit well only in sunny, well-lit areas, so there should be no shading (you should not plant sea buckthorn next to tall crops).
The root system of sea buckthorn is powerful and spreading, so near groundwater it can freeze due to temperature changes. Also, due to the characteristics of the root system, Jamovaya should be planted separately; proximity to any crops is undesirable.
In order for pollination to occur efficiently and pollen to fall on the pistils of the female plant, when planting a male specimen, the direction of the wind is taken into account.

Soil preparation

To plant a young annual Jemova bush, it is enough to dig a hole 50 × 50 cm and fill it with a nutrient mixture. Drainage is placed at the bottom, for example, river sand, a bucket of organic matter (compost, humus), mineral fertilizers, for example, 200 g of superphosphate, are poured on top, and sprinkled with a loose top layer of soil until a flat surface is formed.

Selection and preparation of seedlings

Plants that have no signs of diseases or pests take root well, so it is important to inspect the bushes in detail before planting. If it is possible to assess the condition of the root system, then you should pay attention to its development - the seedling should have 4-6 skeletal roots. The optimal height of the above-ground part is about 20 cm.

Important! When planting in spring, the seedling can be soaked in water for a couple of hours, if the root looks dried out; when planting in autumn, all foliage is removed from the plant.

Algorithm and landing scheme

The optimal planting pattern for sea buckthorn is 3 × 2.5 m, but the distance can be increased. The seedlings are placed in the prepared holes, straightening the roots (with the root system open). It is recommended to plant grafted sea buckthorn on a small mound so that when watering, the grafting site does not end up in the ground. Self-rooted sea buckthorns can be buried - they will send out additional roots.

Important! The support must be placed before planting sea buckthorn.

Subsequent care of the crop

Growing Jam sea buckthorn does not cause difficulties even for novice gardeners.

Necessary activities

Feeding. Jam is undemanding to soil fertility. In the first year of planting, you don’t have to feed it at all if the bush was planted in fertilized soil. Already fruit-bearing adult specimens need to be fertilized - in the spring they are fed with nitrogen-containing fertilizers, and in the summer and autumn - with phosphorus-potassium fertilizers.
Processing the tree trunk circle: weeding and loosening. To limit growth weedTo prevent the formation of a dry crust on the surface and retain moisture in the soil, it is recommended to mulch the tree trunk circle of the bush.

Reviews

Summer residents who have tested the cultivation of bushes from their own experience leave the following reviews on the Internet about the sea buckthorn variety Jamovaya.

Lidia Ivanovna, 57 years old, Yekaterinburg city

It is very difficult to choose a frost-resistant variety of sea buckthorn for the Urals; it freezes too often, especially in winters with little snow.The jam plant became a real discovery for me - the bush quickly took root and withstood the winter without loss. I planted it not far from the neighbor’s fence (they also have sea buckthorn) and am looking forward to the vitamin-packed berry harvest.

Dmitry Semenov, 47 years old, Vologda

I planted the Jam variety 5 years ago and was very pleased with the harvest - one and a half buckets of large, very tasty berries were collected from the bush. Of course, the high yield was predictable, because I chose the variety for this reason, but such a quantity of berries was a pleasant surprise for me.

Nina Mezentseva, 39 years old, Orel

I planted the grafted seedling in Jemova in the fall, but it did not survive the winter and froze. It is possible that the seedling itself was unsuccessful, because I tried to follow all the planting recommendations. I’ll try to plant this sea buckthorn again in the spring, I really want to have such a good variety on my plot.
