Planting and caring for strickta juniper
According to the description of experienced gardeners, there is nothing difficult in growing and caring for the Chinese Strickt juniper. It is unpretentious, but in order for it not to lose its attractiveness, certain rules for disembarking and leaving are required.
Seedling and planting plot preparation
Choosing and preparing a planting site is one of the most crucial stages in growing beautiful, healthy trees.
It is a light-loving culture, however, its needles can suffer greatly from direct sun. It is most dangerous for young specimens, therefore it is recommended to choose a well-ventilated place in partial shade.
Attention! This variety prefers neutral or slightly acidic soil.
It is optimal to buy a seedling in a nursery or garden center. There are several guidelines for choosing it:
- it is preferable to buy trees with a closed root system. Ideal - in a container or with an earthen ball;
- young shoots should be visible on the seedling;
- branches should not be dry or brittle;
- you should choose seedlings with a dense, bright green crown, without dry and damaged areas.
The transplant is carried out in spring or autumn. If a seedling with an open root system, it should be planted immediately after purchase to avoid drying out. A tree in a container can wait for a suitable time to transplant.
The general algorithm is as follows:
- prepare a pit with a volume of 2-3 times larger than the size of an earthen clod with roots;
- leave a distance of 1.5 - 2 m between the holes;
- fill the drainage (broken brick or pebbles) at the bottom of the pit;
- deepen the seedling, leaving the root collar above the surface;
- sprinkle the tree with a mixture of sand, peat and turf;
- shelter from the sun;
- water abundantly.
Attention! When planning plantings, it should be borne in mind that the juniper does not tolerate transplanting well.
Watering and feeding
Juniper Chinese Strekt is not too picky about moisture and tolerates drought quite well. For several months after planting, he needs to ensure regular, abundant watering.
In dry summers, it is watered 2 - 3 times so that each tree has up to 30 liters of water. When growing a Chinese variety in ensembles, it should be borne in mind that excess moisture is destructive for it, therefore, it is necessary to select crops with a similar irrigation regime.
But dry air can be very harmful, so it is recommended to often spray the crown. To avoid burns, do not allow water to get on the needles; on a sunny day, spraying should be done in the morning or in the evening.
Once a season, at the end of April or in May, the plantings are fertilized. Mineral complexes for conifers have an optimal composition.
Mulching and loosening
Mulching is optional. To avoid the rapid drying of the topsoil, less watering and get rid of weeds, you can use mulching. Chips or pine bark are used as mulch.
The Chinese juniper has a developed strong root system, so only young plants need loosening. It must be produced shallowly so as not to hurt the delicate roots.

So, at the end of autumn, trunks are mulched with a thick layer of peat, and young trees are completely insulated with spruce branches. The crown can suffer from heavy snowfall, so the branches are tied to the trunk.
If the winter promises to be extremely frosty, for preventive purposes, you can insulate the plantings with burlap, agrospan or other covering materials. You can shoot the shelter at the end of April. It is advisable to choose a cloudy day for this, so that the plant adapts to the sun's rays.
Features of caring for Strickt juniper at home
Junipers are rarely used as houseplants. Despite the fact that this is an evergreen culture, it, like all conifers, needs a dormant period, therefore it is demanding on the temperature regime. However, now with increasing success these small trees are kept in living quarters. On the forums of indoor flower lovers, you can see photos in which the Chinese Strickta juniper not only grows at home, but is also used as an element of whole plant compositions.

- pour drainage on the bottom of the pot to avoid destructive stagnation of moisture;
- after transplanting, sprinkle the top layer of earth with mulch and sprinkle with fertilizer for conifers;
- water sparingly - in summer as it dries, in winter no more than twice a month;
- often, up to several times a day, spray the crown with water from a spray bottle;
- in winter, carry the pot away from heating appliances;
- fertilize in spring and summer every 2 weeks with mineral complexes added to the water for irrigation;
- the pot should be on the sunny side. In summer, avoid direct sunlight on the crown;

Reviews of Chinese strickt juniper
Natalia Malchuk, 32 years old, Podolsk
The year before last, we bought a small cottage. There are still few plantings there, but there are three Chinese juniper trees. In some places it had yellow needles. I cut it off and thought that the trees were drying out because no one watered them while the dacha was being sold. And, of course, I started watering every day, but it was necessary to treat. Only ruined everything.
