Application in landscape design. A hedge or a flowering alley made from garden jasmine looks good. The original appearance allows it to be used as a single plant. Looks interesting and elegant with other shrubs, especially well combined with hydrangea, weigela, spirea.
Purchase of seedlings. Examine the seedling carefully for disease and damage. It must have several buds and healthy roots. The best time for planting is the beginning of autumn or spring (before the leaves bloom).
Location and landing. In order for the mock orange to please with lush flowering, give it a sunny place, it will also grow in shaded areas, but the flowers will be rare and small, and the branches are too elongated. The soil prefers moist, consisting of humus, sand and leafy earth, in a ratio of 1: 2: 3. The size of the planting pit is 60x60x60; at the bottom, install a drainage made of broken brick with a layer of about 20 cm to prevent prolonged stagnation of water.
To create a hedge from this shrub, observe the distance between the seedlings of 50-80 cm.The distance from the shrub to the nearby growing plants and structures should be 1-1.5 m. Having covered a layer of soil mixture, set the seedling so that the root collar is level with surface, with a strong deepening there is a risk of decay. Then it remains to fill and tamp the hole with fertile soil and water, for this, 2-3 buckets of water are poured under each seedling. After 1-2 days, cover the trunk circle with peat.
Caring for jasmine is not difficult, it includes the mandatory maintenance of moisture, especially during periods of drought and flowering. Do not forget to periodically feed, cut, inspect for pests and diseases.
Watering. Abundant watering from spring to autumn. Once every seven days, pour 2-3 buckets of settled, warm water under each bush, water every other day during flowering. On hot days it is recommended to spray periodically, except during the flowering period.
Loosening, mulching. After watering, weeds are removed and the soil of the trunk circle is loosened. After planting, mulch with a layer of peat about 5 cm.
Top dressing. After the end of flowering, fertilize with wood ash. The next year after planting in early spring, complex mineral fertilizers are applied, after diluting 10 liters of water: 30 g of superphosphate with the addition of 15 g of urea and potassium sulfide.
At the end of autumn, they are fed with phosphorus-potassium fertilizers.
Trimming and shaping. The shrub requires annual pruning to create a beautiful, well-groomed appearance and maintain the desired height. The fact is that flowering appears on last year's shoots, and flowers appear on old branches very rarely, as a result of which the bush looks messy disheveled. To prevent this, you need to cut the branches immediately after flowering to the shoots of this year, which are located below. Next year they will delight with abundant flowering.
In autumn, it needs sanitary pruning: thickening, dry and damaged branches are removed. Rejuvenating pruning is also carried out, for this, in the spring, the trunks are cut to the soil level, only a few are left, shortening them to 30-40 cm. Due to this, young strong shoots will grow closer to autumn.
Bloom. It blooms in May-June, with fragrant large white, sometimes cream or yellowish flowers, which are collected in racemose inflorescences of 5 or more pieces. Inflorescences are attached to the tops of last year's shoots. The flowers have a pleasant, sweet aroma.
Reproduction. Propagated in several ways: by layering, cuttings and seeds, dividing the bush. Seed - generative method is quite long, vegetative is most often used - by cuttings and layering.
Green annuals, well-developed shoots are suitable for propagation by cuttings. The procedure takes place in June. Two or three pairs of leaves are left on the cuttings, the presence of one internode is also required, the remaining leaves and inflorescences placed below are cut off with garden shears. Further, cuttings are set in a previously prepared sand-peat mixture and covered with a glass cap. For successful rooting, you need diffused light and daily spraying.
Another affordable and simple breeding method is by dividing the bush. To do this, in spring or autumn, the bush is dug up, the roots are carefully cleaned from the earthen coma, divided into two or more parts and immediately planted in prepared planting holes.
They are propagated by layering in this way: in the spring, a healthy lignified branch is bent to the ground and fixed in specially prepared grooves. A layer of sand and peat is poured on top. After 1-1.5 months, new shoots should appear. At the beginning of autumn, they are disconnected from the mother plant and planted in a permanent place.
Diseases and pests. Quite rarely, it is exposed to diseases, most often due to improper care.
With insufficient moisture, the leaves curl, deform and lose their natural beauty. The plant should be properly watered and sprayed.
It happens that flower buds wilt ahead of time, this indicates a lack of light.
A sharp drop in air temperature can provoke the development of a fungal disease - gray rot. It manifests itself as brown, vague spots on the leaves. To cope with the disease will help the treatment of spraying the bush with Bordeaux liquid and the removal of affected leaves and shoots.
Sometimes it suffers from pests: aphids, spider mites and leaf weevils. Weevils shake off the branches and treat the bush with chlorophos.
To get rid of aphids, they are treated with Karbofos, and a 2% solution of phosphamide will help to overcome the spider mite.
Philadelphus in winter. Frost-resistant shrubs do not require special shelter for the winter.
Interesting Facts. Philadelphus is named after the Greek king Ptolemy II Philadelphus.
