Overview of Flower Propagation by Cutting
Below is an introduction to the relevant aspects of flower propagation for netizens, an overview of flower propagation by cutting. Next, the editor will provide an introduction.
Propagation by cutting is one of the most common methods in flower propagation, characterized by fast propagation speed, easy collection of cuttings, minimal genetic variation, and convenient management. Here is an overview of the flower propagation by cutting method:
One, Branch Cutting Method
1. Hardwood cutting involves taking one-year-old dormant branches of deciduous flowering trees, cutting them into 5 to 10 cm long pieces, usually with 2 to 4 nodes. Insert them into a prepared cutting bed, leaving about 1/3 exposed above the surface, and water after insertion. Single bud cutting can also be done, with the cutting having only one bud. With the bud as the center, leave 1 to 2 cm on each side, slightly removing the bark from the opposite side of the bud. Insert the cutting into the bed, slightly covering the bud with soil (to avoid direct sunlight). Water after insertion and finally cover with plastic film to save material.
2. Semi-hardwood cutting is often done during the growing period of some evergreen woody flowers. Take the current year's unripe branches as cuttings, or young branches that grow after flowering. Leave a little bark on the part of the 2-year-old branch, leave 2 leaves at the top of the branch, insert into the soil, 2/3 into the ground, water after insertion, and plastic film can also be used for protection.
3. Softwood cutting, also known as young branch cutting, is commonly used for herbaceous flowers or greenhouse flowers, such as chrysanthemums and carnations. Cut young branches 5 to 10 cm long, leaving 1 to 2 leaves at the top as cuttings. Insert into the seedbed, water after insertion, and set up a low shed, covering with reed curtains.
Two, Leaf Cutting Method
Leaf cutting is a method of using whole leaves or parts of leaves as cuttings. The leaves used for leaf cutting must have the ability to root and sprout. There are many types of herbaceous flowers that can be propagated using leaf cuttings, such as begonias, tuberous begonias, and African violets. The parts of the leaf that can root include veins, edges, and petioles. For example, when propagating begonias, several veins on the leaf can be cut and the leaf placed flat on the surface of the cutting bed, from which roots will grow. For tuberous begonias and chrysanthemums, the base of the petiole is inserted into the bed, from which roots will grow and then sprout. Therefore, when propagating begonias, it is necessary to ensure that the veins of the leaves come into contact with the cutting medium, while for tuberous begonias or chrysanthemums, the petiole must be inserted into the bed to root.
Three, Root Cutting Method
This method uses roots as cuttings and is limited to species that can easily produce new shoots from the roots, such as peonies, Chinese trumpet creepers, and sedum. For peonies and Chinese trumpet creepers, select strong roots, cut them into 5 to 10 cm sections, and insert them into the cutting bed or completely bury them in the bed. For small herbaceous plants like sedum, cut the roots into 2 cm sections and scatter them on the bed surface, then cover with soil. Both methods require watering after insertion, and the bed soil should be kept moist.
Management after cutting mainly involves watering, shading, and preventing evaporation to avoid water loss affecting survival. Since the cuttings do not have roots but have a small amount of leaves on the above-ground part, they only have the function of water evaporation without absorption, which can lead to an imbalance of water in their bodies. This can only be balanced after roots develop. Therefore, it is necessary to keep the soil moist and shade the area during cutting management, ventilate and expose to light in the morning. Water after rooting and gradually increase the duration of sunlight. Weeding and pest control should be done as needed, and fertilize once after new leaves grow. Once the plants are strong, they can be transplanted.
