Cutting
The cutting is a part of the plant – a fragment of stem, leaf, tuber, rhizome, root – which, under suitable conditions, can emit roots and give rise to a large number of seedlings identical to that from which they derive. For this to occur, each part must be equipped with at least one gem . There are different types of cuttings and the main classification is based on the part taken: stem cutting, leaf cutting, root cutting. Recommended period Spring or autumn , never during vegetative rest as the plant would not be able to emit roots and shoots. From evergreen speciescuttings can be taken at any time of the year, as long as the climatic conditions are adequate. Ambient
The ideal temperature is between 18 and 21 ° C with medium humidity.
The most suitable soil is made up of 2/3 of sand and 1/3 of peat. To promote rooting, the base of the severed part can be treated with so-called “rhizogenic hormones”, growth hormones that stimulate strong and healthy root development.
The light must be diffused, never direct. Stem
cutting The stem or branch cutting is called: “ herbaceous ” when the apical part of a branch is taken; ” Semi- woody“When the selected part is still young, partially wooden; ” Woody ” if it comes from a woody branch. The latter is practiced in autumn, pressing the base with a hammer, to facilitate the emission of the roots. Stem cutting without leaves · Cut a piece of healthy stem into 7 cm long segments with at least one bud and insert them into the soil.
· Water and cover with a clear plastic sheet to keep the soil moist . Use sticks planted in the ground to keep the plastic away from the cuttings.
· Lift the sheet from time to time to avoid condensation inside the pot and possible rot .· After a few weeks, leaves and roots
will sprout from the stem segments . Stem cutting with leaves
It takes on different names depending on where it is taken. Apical , if a vegetative apex and at least two leaves are present in the stem;
· Cut the shoot just below the leaves, it must be about 8-10 cm long;
· Water and cover with a clear plastic sheet to keep the soil moist. Use sticks planted in the ground to keep the plastic away from the cuttings.
· Lift the sheet from time to time to avoid condensation inside the pot and possible rot. After three weeks, remove the plastic sheet. Basal , if the shoot is taken from the base of the stem;
· Take a sprig with at least two leaves and plant it in the soil until the leaves are level with the soil;
· Water and cover with a clear plastic sheet to keep the soil moist. Use sticks planted in the ground to keep the plastic away from the cuttings.
· Lift the sheet from time to time to avoid condensation inside the pot and possible rot . After three weeks, remove the plastic sheet. Leaf cutting
There are two variants of this method which is practiced with plants with fleshy, healthy, strong and fully developed leaves. Leaf cutting with stem
· Cut the stem at the height of the soil and insert it into the new pot keeping the leaf out
· Water and cover with a transparent plastic sheet to keep the soil moisture
· After a few weeks, pot the new leaves individually sprout at the base of the old leaves Leaf cutting without stem Take
the fleshiest and healthiest leaf and cut the ribs of the lower page with a sharp knife.sand by placing the lower page on it and block it with some small U-hooks, to make the engraved veins adhere completely to the substrate;
· Water and cover with a transparent plastic sheet to keep the soil moist.
· After a few weeks you can remove the remains of the old leaf and individually pot the new leaves . Root cutting
This technique is less used than the other versions.
Cut horizontally segments , about 10-15 cm long, of the underground system of a plant (root, tuber, rhizome
) .not very deep: that it is just under the surface of the soil
Water to keep the soil moist
When the first leaflets appear it means that new roots have formed which must be potted individually Offspring
Vegetative or agamic multiplication technique which consists in reproduction without detachment from the mother plant. It is applied to indoor or outdoor plants with sufficiently long and elastic branches. Recommended
period The ideal time to do this is in spring-summer. How to proceed
· Choose a long branch, flexible and possibly young: it emits roots faster
· Detach all the leaves present on the branch except the apical ones
· Bend the
branch, bury it at a depth of about 5 cm and fix it with a U-bent iron of the branch and treat it with substances that stimulate the emission of roots
. · Water abundantly and keep the soil moist.
In 8-12 months, new roots are formed and therefore a new plant that can be separated from the mother plant and placed in the final position. Division of the tufts
. Reproduction method suitable for perennial herbaceous plantslarge, both for apartments and for outdoor use, such as large bushes in the ground. It consists in dividing the plant in two and allows to obtain a greater number of specimens, identical to the mother plant but stronger and more luxuriant. Recommended period Autumn , during the vegetative rest or in early spring , before the vegetative restart, so that the young plants can develop fully. How to proceed
· Remove the plant from the pot and clean the roots from the soil, if necessary wash them with water;
· Shorten the leaves and stemsat about 15 cm in height, to reduce the subsequent loss of water by evaporation; · Divide the plant into tufts (group of stems with sprouts, with a common root system) and eliminate the central part that is usually exhausted and old;
· Plant the tufts in a new pot with fresh soil and water.
If the plant is small in size, a sharp knife is sufficient; for the plant in the ground, you can use a sharp square spade , in order to clearly separate the tuft of interest, or, alternatively, use two pitchforks, back to back, tuck into the center of the stump and pry. The division can also be carried out on plants with a rhizome or tuber as long as each piece has at least one bud. Margotta
An ancient reproduction method that allows to obtain specimens identical to the mother plant, through the incision of the stem , without twisting. It is performed on plants with woody branches that do not bend easily, for example garden magnolias or houseplants. Recommended period
During the vegetative activity, that is in spring-summer : the plants are in the best condition to emit roots and shoots. How to proceed
· Choose a healthy branch, sturdy and woody, possibly lateral · Make a diagonal incision 2-3 cm long and shallow
not more than 8-10 cm below the first healthy apical leaves to avoid breaking the branch
· Gently open the cutting edge and introduce some peat and sphagnum
· Place a plastic sheet around the cut, up to 6-8 cm above the incision, like a bag and fill it with a mixture of soil , peat and sphagnum . Close the ends of the bag with waterproof tape to maintain moisture
When you see the new roots sprout cut theLayer , remove the bag and plant the stem, supported by a stake, in a vase.
