Vegetative propagation of herbaceous and ornamental plants

August 12, 2017 17:52 | General Information About Plants

Vegetative propagation of ornamental grasses and annuals and perennials is carried out by dividing the bush and roots, green cuttings, root cuttings, tubers, bulbs and corms and root suckers. bush division - the most simple, practical and common method of propagation own rooted shrubs, such as lilac, spirea, mock orange, and

dividing the bush is the easiest way forward vegetative propagation of perennial vegetable and ornamental crops.Simply dig a shovel of the big old bush and move to a new location

Dig bush (part of it) and carefully divide it by hand or cut with a knife.This should be done carefully so as not to greatly injure the roots, each received delenki must have at least one escape or development of a viable kidney continuation

Cut apical or middle stalk with branches at the base of the mother plant leaf.

2. The lower leaves removed, middle and upper leaves are large cut to half and dip the base of the cuttings in a growth drug to stimulate rooting.

3. After 18-20 hours, r

emove the stalk, rinsed with clean water and put in light the ground substrate.

4. To ensure the required moisture stalks should be watered regularly, and cover the top with plastic wrap or a jar

rhizomatous herbaceous perennials, such as Astilbe, helenium, delphinium, phlox and other.To do this, dig up the mother bush or a portion thereof with a clod of the earth and share the shovel, knife, shears or gently separate the arms apart.Each of the subsidiary must have at least 2-3 of the kidneys or renewal shoots.Ranotsvetuschie plants divided and planted in the fall, plants, entering into a phase of flowering in summer and autumn, it is recommended to divide in spring or autumn after flowering.We separated subsidiaries plant can shorten the length of the roots and dip the root system in the slurry of mud and manure.Contained in manure growth stimulators intensifying the development of the root system that promotes rapid rooting of plants.Sometimes disinfection recommended the formation of

green stalk cut off the lower leaves and truncated to half of the large middle and upper leaves.It is necessary to establish a balance between the amount of leaf mass, flow the nutrients and moisture evaporates and only the emerging root system

1. The apical stalk.

2. Median stalk.

3. Sharing with one eye or sheet.Qualitative green cuttings should have 3-5 buds, they are stronger and more viable.With a shortage of planting material, you can rooting cuttings and having at least one bud (eye), and the petiole with leaf

/. autumn before frosts dig mother plant out of the ground and cut off the main root at the base.Thick roots are divided in the direction of growth for some segments of 5-7 cm each.

2. These root cuttings placed in a box filled with sand or light land, the substrate.Cuttings are stuck into the substrate vertically.

3. Cuttings can be expanded horizontally, sprinkle with the ground and stored for winter in a cool place, avoiding freezing.

4. capacity with spring cuttings transferred to a warmer place and allowed to germinate, and then became strong plants are transplanted into open ground

ated roots separated plants with a weak solution of potassium permanganate.A number of herbaceous perennials, forming a powerful rhizome, traditionally propagated by dividing the rhizomes . rhizomes are cut into pieces so that each part of the divided rhizomes - delenki - had at least 2-3 resuming kidney.dividing the time depends on the type of culture: the irises are divided in July after flowering peonies in the second half of August to the beginning of the formation of young adventitious roots, eland, Tigridia, lily of the valley propagated, pre-sprout roots in the greenhouse, which are then in March divided in such a way that eachsegment had 1-2 buds resume and planted after the frost.Many herbaceous cultures can be propagated by softwood cuttings . This method is more time consuming than the simple division of the bush, but it is often indispensable to plant breeding stage, when there is no seed material. Summer or green stalks are cut usually in June or July.When cutting the upper section of the kidney is doing right, and the lower oblique, if the stalk has more than two kidneys, the lower leaves are removed completely, and the average half-truncated, especially if it is large.

To speed up the process of rooting the lower end of the cutting is placed in an aqueous solution of growth stimulants, such as for example IAA and indolebutyric acid.The maximum concentration of growth promoters should not exceed 25-50 ml / g.After drug treatment RostoVs which lasts at least 15-18 hours, cuttings removed from the solution and washed in clean tap water.After that, start planting green cuttings.They planted obliquely to a depth of no more than 1 cm in light land-based substrate of sand and peat.For successful rooting of cuttings need temperature 20-24 ° C and humidity of 85-100 %. This humidity level is achieved by repeated watering during the day, and a transparent plastic film coated.Under the film is set warm and humid climate conducive to rooting, you can instead of film to cover the seedling transparent glass jar, the effect will be the same.
