Phlox paniculata (autumn planting and cuttings).
Bushes phlox paniculate 3-4 years planting strongly expand and lose their decoration. In the middle of the bush old rhizome phlox odrevesnevaet begins to bulge out of the ground and dies, and the type of bush blooms deteriorate (small flowers on inflorescences of small, weak and short flowering, short stems, small leaves). With the loss of ornamental shrubs phlox dig, divide and transplant.
Phlox paniculata can be planted in the fall - from mid-August and early September, or in the spring - the end of April and the first decade of May. Autumn planting large delÑ‘nki phlox for rapid establishment and good overwintering and spring bush can be divided into smaller parts (this is especially true when propagated varieties of phlox). At the same time, the fall planted in a permanent place and grown phlox grown from cuttings spring terms of propagation.
Phlox grow well in loose loamy soil. Before planting phlox in such soil is added rotted manure or compost; in clay - and even sand, and sand - and even peat. In uterine bushes phlox stems cut in half, carefully dig up the bushes, shake off the excess land and divided into several parts of the hands (trying not to resort to the use of tools, so as not to injure the roots of the fission). At the base of the stem and roots of young phlox formed vegetative buds, from which spring grow new shoots; rhizomes without vegetative buds die after transplantation.
Each delÑ‘nka phlox should be in the first year growth of about 8 shoots. From one major uterine bush phlox can get 20 or more delÑ‘nok. When dividing remove old lignified part of the rhizome and immediately put into the prepared hole delÑ‘nki as rootstock in phlox dries quickly.
Between the planting hole should be at a distance of about 40 cm; at planting beds of 1 m. m is placed not more than 6 plants. The root system of phlox is superficial, so the planting hole to straighten the roots and placed almost horizontally. Vegetative buds sprinkled ground phlox (after settling, the top layer of the soil should not be more than 4 cm) - with deep planting phlox kidney poorly developed, and at shallow planting kidneys can vymerznut winter.
After landing delÑ‘nki abundantly watered (about 2 liters of water per plant); for the good of their rooting desirable to irrigate every 2-3 days during the sixteen days if there is no rain. Precipitated and dried up after watering the soil loosened around delÑ‘nok and mulching with peat, humus or peat compost layer of about 4 cm. Planted late delÑ‘nki phlox insulated further fine shavings or chopped straw.
Phlox cuttings harvested in August - September (for cuttings taken neodrevesnevshie upper part of the stems) are seated in a cold frame (nurseries) rows (distance between cuttings 10 cm between rows 15 cm) or in pots placed in a cool, bright room. In the winter cuttings of phlox insulated from freezing dry leaves and peat, and the top cover film; spring film shoot, and in establishing warm weather insulation from cuttings gradually removed.
