Seed propagation is not the most common method of growing plants, but certainly very interesting. In addition this method of reproduction leads to new forms of plants, such as other colors of flowers (Gloxinia, orchids).
For a start is better to try to grow from seed easy annuals, they bring a swift and tangible results. This in turn stimulates many try to grow from the seeds of the more interesting plants such as cacti, cycads, paportniki or Saintpaulia. Seeds are more rare plants sprout more difficult, but this may in turn be more interesting. Many perennial houseplants grow slowly, so that it may take a couple of years irst they reach a significant size, so if you want to buy the seeds at the store, then read the instructions carefully to them, indicating the dates of germination, planting and flowering. If you need a lot of plants, make planting on a tray, or use pots.
Sowing seeds. Seeds for planting should be first in all fresh and uninfected. Long germinating seeds are sown in January and February. Rapidly germinating seeds in March and April, since the earlier sown seedlings will vytyagivatsya due to lack of light. Long germinating seeds of such plants such as camellias pandanus, asparagus, palms and other plants with a solid skin require pretreatment before sowing. It is vymatsivanii seeds for 3-5 days in water or boiling water scalds, carefully peel the thick seed nadpilivanii good result seed treatment aloe. Undamaged leaves of aloe small store 25 days at a temperature of +3 В° C. After this time, squeeze the juice from the leaves and seeds are soaked in it. As a result of this treatment, the seeds be afoot faster and faster flowering plants produced from such seeds. To decontaminate the soil 1-2 times scald boiling water or just ignited. This should not be done at sowing of heather plants.
Seeds are sown in pots or trays.
Sowing on the tray. It is necessary to fill a tray with a mixture of seed, usually a mixture of the clay and peat, which are suitable for most seeds. Do not use the ready-mix for growing indoor plants, as the levels of these nutrients in higher and may inhibit germination. Level the ground with boards or a piece of hardboard, then gently tamp it. Necessary that the surface of the land was leveled. Then spread the seeds on the surface as evenly as possible. If seeds are not too small or on the package does not say that they should leave the light, prisypte them on top of a thin layer of soil. The thickness of the layer of soil must be equal to the thickness of the seed. For a more uniform distribution of the soil, you can use an old kitchen sieve. Carefully pour, using the watering can with fine spray. Then place the tray in teplichku or cover with a piece of glass. Follow the instructions on the packet of seeds with respect to temperature and light conditions.
Sowing in a pot. It should be at the bottom of the pot to put drainage consisting of shards of gravel and coarse sand. Fill the pot light soil mix and tamp the seed of its banks. Carefully align the soil in the pot. Sow the seeds evenly, such as the sprinkling of salt. Sprinkle seeds on top of soil layer thickness with the size of seeds. Pour the ground in a pot of spray or dip, putting the pot in a basin of water, whose level must be below the level of soil in the pot. When the surface of the earth in the pot becomes wet, remove the pot and allow to drain off excess water. Place the pot in a greenhouse, cover it with glass or plastic bag, as shown in the figure. At the same distance from the ground to the glass should be 1 cm at sowing small seeds and 1,5-2cm at posevedolee large seeds.
A little secret: if you sow the seeds of dustable, for convenience, to be seen how they distributed the seeds are mixed with small amounts of river sand and seeded. (Light Sand is clearly seen in the black earth) Also at sowing seeds of dust showering the ground before sowing is better, but very abundant. Care for the crops is to periodically spray, careful watering from the pallet, wiping sweaty glasses and a light ventilation. Pay particular attention to make sure that nebylo peresushki or waterlogged soil. When you see shoots the glass was removed and the plants put closer to the light, but the first 1-2 days pritenyayut from direct sunlight.
Swordplay. For the formation of a strong root system for growing the seeds hold picks. Picks spend 2-3 times, each time the plants are transplanted in the more fertile earthen mixture. There are plants that do not bear picks, but there are plants for better growth requires 4.5 picks. If there are such features, then read about it in the encyclopedic section. Diving plant zaostennym peg (it can be done from a simple pencil). Technique is this: right hand peg stuck into the ground around the seedling, and the left hand gently lift the seedling from the ground. Diving in moderately moist soil, and plants sprayed dive. For better rooting for 1-2 days dive plants can be covered with glass.
Reproduction from cuttings.
Most house plants can be grown from stem cuttings, so this method of propagation is the most common. Some plants take root even in the water, the other vice-versa are more demanding and require treatment with hormones and greenhouse conditions. Most of the plants propagated from cuttings taken from the upper parts of shoots mainly in spring and summer. In oleander and ficus take thicker, stiff branches. Dieffenbachia, dracaena, philodendron and other plants reproduce segments of the trunk (about 5 cm).
Technique of preparation of the cuttings. Cuttings cut sharp, clean knife slanting cut, just below the eye, intact branches. Cuttings of plants containing the leaves of many Vova (succulents) dried before planting. Herbaceous cuttings are planted at a depth of 1-2 cm, woody - little deeper. For better rooting of cuttings need moist air, so the dish from the cuttings covered glass jar or plastic bag. Cuttings do not require the hiding of succulent, fleshy plants, as well as fuchsia and geraniums. Cuttings of figs, araucaria, eyforby and other plants that emit latex dipped in warm water until not stop the selection of juice, then slice sprinkled with powdered charcoal drevestnym.
Care of cuttings is sprayed with warm water, regular spraying, wiping a sweaty glasses, or package, shading from the sun. In this case, aeration is carried out twice a day - morning and evening. If you find rotten cuttings, they should be immediately removed. Seedlings of many plants can easily take root if placed in water (this is not applicable for succulent plants). Thus it is necessary to make sure that water does not blossomed and sour. Rooted cuttings can be planted directly into pots, but after transplantation 1-2 days to avoid direct sun.
Reproduction plant leaves. Rooted leaves of the following plants: Begonia Rex, ahimenes, peperomiya, sansevera and other plants with more or less thick or fleshy leaves. Reproduction of the worksheet - the usual method of propagation of Begonia Mason, begonias royal, sanseverii, streptokarpusa. Sansevery leaves cut into pieces 5 cm long, with begonias part of the leaf with the base up to 4 cm, and planted in moist warm sand. To list does not fall flat on the ground, placed him under supporting stick. At high temperature (30-35 В° C) and careful watering pieces of leaves give the roots and form a young plant.
Reproduction whole leaf - used for breeding succulents (stonecrop, echeveriya, jade, etc.), Begonia Rex. In the leaves of Begonia rex from the bottom of their hand, you must first make an incision all the thick stems, succulent plants have fleshy leaves and large pre-dried within 2 days. Ground cover damp sand in which large leaves dipped lower part, and the small bag flat and lightly pressed against. Leaves of Begonia rex large in size, so we have to put the leaves on the bottom of the sand surface and press them in several places with matches to the sand.
Reproduction of the whole leaf with petiole - typical for Saintpaulia, Gloxinia, small-leaved peperomii and some types of begonias. To do this, take an adult healthy leaves taken from the base of the plant. Petiole should be no more than 5 cm in length. The tip of the stem is cut across the strictly sharp knife, dipped in a solution of phytohormone (see preparations). Graft is placed in a pre-done to a deepening of the soil, so that the underside of the leaf was turned toward the wall of the pot, the sheet must not touch the soil, and rise above it. Reproduction of root cuttings - is used for plants such as Aralia, Bouvard, dracaena, arrowroot, roses and other plants with gnarled roots. The roots of such plants, cut into pieces with knots, put in good soil.
Reproduction by layering. Weighed down by layers are called to the ground escapes the uterine plants. Under the influence of soil moisture and sap flow stagnation due Crouching low shoots, they take root. Propagated by layering lemons, roses, rhododendrons, ivy and other plants. Best carried out reproduction by layering in spring annual shoots. The middle part of diverted a branch must be immersed in the earth, and the top is raised above it. Thread tied to a peg. In the place where the branch will be immersed in the land, it makes the incision of the cortex toward the top of the branches.
Plants with thick, stiff stems (Aralia, Ficus, dracaena), which can not be weighed down to the ground, they turn in an upright position. To do this, take a plastic bag on a tree make a cut or remove the crust in a narrow ring. Package filled with loose soil or peat moss, which all time must be moist. The package is fixed around the notched hole. By rooting incised branch cut. The remaining lower part can be used for cuttings. This method of propagation is used when the lower part of the trunk of the plants were bare, and it has lost its decorative appeal.
Reproduction by division. This method is typical for the plant well grow in width (aspidistra, Cleve, Freesia, tsiperus, arrowroot, Agapanthus, asparagus, paportniki, etc.). When transplanting in the spring, these plants are taken out of the pot divided in half or more parts. To do this, use a well sharpened knife. Each part must have a small amount of roots and growth buds. Reproduction of tubers. Used for breeding Gloxinia, Caladium, tuberous begonias, etc. The division produces tubers after they have germinated in a warm and humid conditions. Tuber with a sharp knife cut into several pieces. It is important that each division of the tuber had At least one kidney.
