A complete Collection of cutting Propagation methods of Flowers

Growing flowers can be enjoyable and comfortable, and certain methods are needed to grow more flowers. Cutting is the most commonly used method in flower propagation. What are the methods of flower cutting propagation?

1. According to cuttings material

According to the cutting material: branch cutting, leaf cutting, leaf bud cutting, root cutting.

1. Branch cutting: the method of cutting with plant branches as propagation material is called branch cutting, which is the most commonly used method. Those that use the tender part of herbaceous plants as cutting materials are called herbaceous cuttings; those that use green twigs that have not been fully lignified as materials are called tender or green cuttings; those that use old branches that have been fully naturalized as materials are called hardwood cuttings or mature branches; those who use dormant branches as cuttings are called dormant shoots: those that use relatively young and unelongated buds as materials are called bud cuttings. Cutting with the tip of the branch is called cutting with the tip; cutting with the branch that cuts off the end is called normal cutting or cutting off the shoot, which is also the most common cutting method.

2. Leaf cutting: the method of cutting with leaves as materials. This method can only be applied to the species that can produce adventitious buds and adventitious roots from the leaves, such as tiger tail orchid, hairy leaf begonia, big rock tree and so on. Most of the plants that can insert leaves have stout leaves, veins or thick leaves.

The commonly used leaf insertion methods are as follows:

(1) flat method: also known as whole-leaf sowing. First cut off the petiole, then lay the leaf flat on the sand surface, fix it with bamboo needles, and make it close to the sand surface. If it takes root on the ground, young plants can be produced from the leaf edge. Begonia produces young plants from the base of leaves or veins.

(2) Direct insertion: also known as leaf insertion. If the petiole is inserted into the sand and the leaf stands on the sand surface, adventitious buds will occur at the base of the petiole. For the leaf insertion of the large pedicel, the small bulb first occurs at the base of the petiole, followed by roots and buds.

Scale cutting: Lily scales can be peeled off for cutting. After the lily blossoms in July, the bulbs are enamelled. After a thousand days of drying, the scales are peeled off and inserted in the wet sand. Bulbs can occur at the base of the scales after 6-8 weeks.

Leaf insertion: also known as slitting and cutting. In this method, a leaf is divided into several pieces and protected separately, so that each leaf forms adventitious buds. Such as tiger tail orchid, paulownia, pepper grass and so on can be propagated by this method.

3. Leaf bud cutting: cutting with leaves with axillary buds, which can also be regarded as a single bud with leaves between leaf cuttings and branches.

This method can be used when the material is limited and more seedlings are desired. This method is often used in the protection of Indian rubber trees, camellia, dahlias, green apples, etc. For Pinus koraiensis and other tree species, the top part of the shoot is removed to promote the activity of the adventitious buds at the base of the needles to form short branches, and then cut off together with the needles for cutting, which is called leaf bundle cutting, which also belongs to a kind of leaf bud cutting.

4. Root insertion: adventitious buds can be produced on the roots of some plants to form young plants, such as wax plum, persimmon, peony, peony, blood grass and other species with thick roots. It is generally carried out when transplanting in autumn or early spring, the method is to dig up the root of the plant, cut it into a root segment of 4-10 cm, and bury it horizontally in the matrix, and it can also make one end of the root slightly exposed to the ground and buried vertically.

Second, according to the cutting medium

According to the cutting substrate: soil cutting, sand cutting, perlite and vermiculite cutting, water moss cutting, water cutting and fog cutting.

1. Soil cutting: soil is used as cutting substrate, which is the most common method. With the different types of soil, the effect of cutting varies greatly, among which the effect of sandy soil and sandy loam is better.

2. Sand cutting: sand is used as cutting substrate. The effect of uniform fine sand is better.

3. Perlite and vermiculite cutting: perlite, vermiculite and other mineral materials are used as cutting media. This kind of substrate has good air permeability and water retention, so it is suitable for the cutting of all kinds of plants, and the effect is the best.

4. Water moss cutting: water moss with strong water retention was used as cutting material. It is suitable for soft cuttings and other special cuttings.

5. Water insertion: it is suitable for plants that are easy to take root in water, such as willow, rose, oleander, dahlia, dragon blood tree, etc., but the water should be changed frequently to keep the water quality clean. Sand can also be put at the bottom of the water to fix the cuttings.

6. Fog cuttings: cuttings are fixed indoors or in containers to provide water or nutrients through spray. This is a special cutting method, which is characterized by no lack of oxygen, easy to observe rooting and so on.

There are many cutting methods, and the propagation methods need to be selected according to the varieties and characteristics of plants.
