How to avoid mistakes at cultivation of saintpaulias? We will consider part 2
In this part how it is correct to pick up the soil, to put and multiply saintpaulias what problems at violation of an agrotechnology can arise.
Landing and reproduction. For landing of violets use the easy nutritious soil consisting of 4 parts of the sheet earth, 1 part of peat and 1 part of sand. It is possible to use also store soil for saintpaulias. For prevention of fungal and bacterial infections the soil should be spilled hot solution of potassium permanganate of saturated color or to steam on a water bath. At the bottom of a pot arrange a good drainage. For protection of a plant from rotting around a root neck it is useful to fill river sand a layer about 1 cm
the Ware for landing should not be too spacious since root system of violets superficial and weak. Height and width of a pot have to be approximately identical. It is important to pay attention to that edges of a pot were without zazubrinok, equal and smooth. Otherwise, thick juicy shanks of leaves are easily injured, the necrosis of fabrics begins, and leaves perish. Anyway the pot is selected strictly according to the plant sizes. Small violets put in pots with a diameter only 5 - 7 cm and in process of their growth replace in more spacious. Tiny grades grow up in the tiny volume of 3 - 4 cm in the diameter.
Saintpaulias sheet shanks or division of the expanded bushes into separate copies breed. Leaflets cut off in the spring and in the summer with a shank 4 - 5 cm long with a slanting cut. They easily take root in water then they are landed in small glasses where they also grow before emergence of the young socket of leaves. At poecilophyllous grades for rooting cut off more green leaflets, they take roots better and are capable to give more food to young sockets.
For the taking roots shanks and children temperature of 24 - 26 °C at the increased humidity of air is optimum. If the top part of a leaf dies off, do not hurry to throw out together with it and the soil from a glass: the young plant arises exactly underground in the lower part of a sheet scape. It is necessary to wait still some time, and soon from the earth young leaflets will appear. The very young young growth of poecilophyllous violets of almost completely light color is also deprived of a chlorophyll. They will receive it from a maternal leaf therefore it is not necessary to hurry to separate it from the socket.
For rejuvenation of the old socket it is possible to cut off the old bush extended on a root neck with a small penk and to implant in water or mix of sand with peat. But there is also less traumatic option of this method. It is that at change of a plant with the extended root neck at it cut off the lower half of roots and put to the new soil, having buried there and the bared root neck. In several months at the next change it will be possible to cut off old roots provided that around a neck the new root system was formed.
Change of violets is made annually in the spring to the new soil, separating at the same time excess sockets. Though not always in the spring: better after completion of blossoming to replace a plant to the fresh nutritious soil that it restored forces for further growth. At the same time it is possible to separate excess sockets. At each change the drainage is also surely replaced with fresh.
On leaves brown spots appear is a result of watering by cold water or solar burns. The damaged leaves should be removed.
Leaves turn yellow - too much sun, too dry or too damp air, overdose of fertilizers.
On leaves and flowers there is a gray raid is the mealy dew or gray decay arising at violation of conditions of keeping. It is necessary to remove the damaged parts of a plant and to make processing by the corresponding fungicide.
Leaves become faintly - green, their edges are bent - too low temperature of contents, perhaps only at night. In that case it is necessary to clean for the night pots with violets to warmer place from a cold window sill.
Leaves violently develop, but there is no blossoming - it often happens at insufficient lighting, contents in the room to dry and cold air, at a lack of food of the soil or at excess of fertilizers to the increased content of nitrogen. It is promoted also by too spacious ware. Besides, to the detriment of blossoming frequent shift from place to place, frequent change and untimely office of affiliated sockets. If not to delete affiliated sockets, then leaves, blossoming poor begin to become shallow or absolutely is absent.
An earth lump damp, but leaves of a saintpaulia of a podvyala, lost elasticity and hang down through edges of a pot. At touch leaves easily separate from the socket - most often it happens in the winter at a low temperature and remoistening of the soil. Fusariosis develops, roots and a root neck rot. It is necessary to loosen the top layer of earth to give access to air to roots and to dry the earth. To remove all separating leaves. It is possible to use them for reproduction, having cut off shanks of rotting 2 - 3 cm higher than the place. If all socket easily gets from the earth, so roots already decayed.
Saintpaulias are subject to attack of a plant louse, the whitefly, a trips, mealy cherveets.
Of course, saintpaulias - flowers not for lazy, they require a lot of attention and efforts. But all this with interest pays off magnificent plentiful blossoming for many months.]
