shows, nurseries, stores are offering more and more new varieties and species.The only limiting factor for the grower may be the price of new products: the planting material is quite expensive.Grow the seeds of a long time, and the passion to satisfy immediate wants.To help nearly always comes a proven method - cloning - namely cuttings.
Propagated perennials had many.But just to divide plants grown is not always possible.Firstly, some of them, for example, with rod root, division is not transferred.For these cuttings - the most acceptable method of reproduction.Second, if the sprawling perennial fits into the design of the garden, it is a pity though.
better this time let grow from cuttings young healthy specimens and then replace the old and accumulated disease.
Cutting can be propagated and the only copy you inherited a rare and very expensive plants.Cuttings can share (without prejudice to its own
vast majority of plants grown from cuttings retain all parent properties.Exceptions are variegated forms and with different colors of leaves - yellow, red, silver.Typically, this form of genetic origin.The cells of such plants may be arranged not only in the stem, so there is a chance of occurrence of instances of green foliage.To obtain plants identical to the mother liquor, when regrowth cuttings they need to be culled, leaving only the retained characteristics of the variety.
for micropropagation using different plant parts.By the end of spring for this purpose can take basal shoots vylamyvaya them at the base of the bush.So many cold-resistant perennials are propagated: delphinium, Phlox paniculata, autumn asters, veronicastrum, yarrow.They quickly formed roots, and plants get strong, stocky, with large caps of flowers (eg, phlox).
Use on cuttings and basal shoots in plants with rosette structure, vylamyvaya them at the base.In this way, easily propagated by popular now, Heuchera, tiarki, geyherelly.And it can be done during the warm season, until the autumn.
Since June, part of the stem cuttings of perennials.They are separated from the plant when it is at its peak.In this case, the terms of propagation for each plant should be treated individually.But there are general rules: the stem should be flexible, that is, when you try to fold it in half it should not crack.In this way, can be propagated phlox, clematis, roses.
Throughout the summer, well take root stem cuttings groundcover.At the same time phlox styloid, Veronica Armenian, thyme, you can use the upper part of the shoots after flowering.
for propagation are selected only healthy plants.If you use the cuttings to flowering specimens already, be sure to remove not only the leaves but also the flower.
better to cut stems in the morning when the plants are nourished night moisture (it will help fill the shortage of evening watering).
better to take root cuttings taken from the upper part of the shoot, but they are worse tolerate winter.The survival rate of cuttings taken from the lower part of the stem - the lowest, and from the middle of the - optimal.
list of plants suitable for green grafting is extensive.Taste of grafted whatever you want to propagate.But success in the cuttings of perennial asters, Aquilegia, bells, chrysanthemum, dahlia, lavender, mint, periwinkle, phlox, pinks, sage, speedwell, thyme, yarrow, Helon guaranteed.
stem is cut into cuttings so that each part was not less than two or three leaf nodes (1), but we can take a longer - up to 15 cm, but in this case more difficult to maintain turgor (elasticity) leaves at rooting.
lower cut made by a sheet or leaf node, retreating 2-3 mm at an angle of 45 degrees.Upper - right angle over the top bud.Due to this lower part of the stem from the top and do not confuse not plant stalks upside down.
have lower kidney leaves are removed completely, trying not to damage it, leaving the petiole (2).Subsequent leaves are pruned by half (3).Cuttings from the latex was washed by water, so as not to clog the cardiovascular system.
There is another way of propagation of herbaceous perennials - leaves.For example, when the multiplication of varieties of primroses, inkarvilley, Phlox paniculata, when there is no other way to get the planting material as soon as the leaves take with friends growers.It is used much less frequently, because it is more laborious in nursing leaf cuttings.
For better rooting stimulants used formation of the root system - liquid or powder.For plants react negatively to waterlogging (eg, phlox styloid) or herbaceous (cloves) are used only powder formulations.The most common - "Kornevin."
For cuttings affected by rotting, you can use stimulants, which include charcoal ("Ukorenitel").Before placing the cutting in the ground, its base is lowered in preparation for a maximum depth of 1-2 cm. The excess powder is shaken off (4).
When using liquid stimulants ("Appin-extra," "Kornevin" "Zircon", etc.) prepared in accordance with the instruction cuttings give solution for 10-12 hours, and a depth of not more than 1 cm (5).
for rooting cuttings need moist and well-drained soil.Classical mixture - equal parts rotted peat and coarse sand.She filled a small parnichok or container (boxes, pots, plastic boxes) having drainage holes.Rooting can also be performed in a clean river sand or perlite (special composition for rooting cuttings, which is sold at garden centers).
to maintain moisture and retain heat cuttings should be under the glass roof of a tunnel under the film (6).Green cuttings planted at a depth of 1 cm semilignified - little deeper.
Cuttings require care.They require temperatures in the range 23-26 ° C and humidity of soil and air, access to the scattered light, and as rooting - occasional ventilation.Glass or film cover on a daily basis should be slightly open, and if the cuttings left on for some time without supervision, to provide ventilation openings.As the roots (in terms of different plants vary) ventilation is gradually increased.
Once the cuttings will be new leaves or increase the growth of planted stems - it's time "young" feed.To do this, use a weak solution of complete fertilizer every 10-12 days.
Terms transplant to a permanent place in different cultures may be different.If the plants develop slowly, it is better to leave them in place of propagation (in the ground) until the spring, at the same time removing the top cover.
very effective way of propagation, which is in the amateur floriculture called "The Nurse".For this sapling is placed next to the mother plant, having covered his glass jar or a cut plastic bottle.You can hide a small container of the plant directly, so as not to disturb the aesthetics of the flower bed.All other things being equal conditions cuttings near the mother plant acclimatized perfectly.
