How to propagate gardenia by cuttings? Teaching you the correct cutting method
Gardenia is a flower that everyone is familiar with, and it is distributed very widely in our country. In many places, gardenia can be seen in parks. In fact, gardenia is not only for ornamental use, but also has certain edible and medicinal value. Nowadays, many people in our country grow gardenia, and when growing gardenia, its propagation methods mainly include cutting propagation, seed propagation and layering propagation. Today, what the editor wants to introduce to you is the cutting propagation method for gardenia.
1. Branch preparation
Branch preparation is the first step of cutting and also a very important step, because the quality of the branch directly affects the survival rate and the growth ability after survival. First, we should choose a gardenia tree with a longer growth period, robust growth and no previous pest or disease problems as the mother plant. Then choose a branch with strong growth and thickness as the cutting, and do not use branches harmed by pests or diseases. Then cut the branch off from the base, and cut it into cuttings of about 18 cm. Cut the base of the cutting diagonally into a cut of about 45 degrees, soak it in rooting water for about 10 minutes, then take it out and dry it to wait for cutting.
2. Substrate preparation
After preparing the branch cuttings, of course, it is time to prepare the cutting substrate. Gardenia is suitable for growing in slightly acidic soil, so when choosing the substrate, pay attention to the pH. It must not be neutral or slightly alkaline, otherwise the survival rate of the cuttings will be extremely low. Then ensure that the substrate is sufficiently fertile, has strong permeability and normal drainage and irrigation. If it is potted, then pay attention to the choice of pot, among which the best choice is a ceramic pot, because the ceramic pot has relatively strong permeability, which is conducive to the rooting of cuttings, and the price is relatively affordable, which can reduce the cost of growing.
3. Cutting at the right time
When cutting, try to prepare the branches when the plant has not yet bloomed, because at this time the branches are very rich in nutrients and the rooting rate is relatively high. After all the preparation work is done, control the cutting density well and insert the cuttings vertically into the substrate, keeping the depth at about 5 cm. Then cover with fine soil and press it firmly so that the base of the cuttings fully contacts the soil, then water thoroughly to promote rooting of the cuttings. After watering, strengthen management, apply additional fertilizer appropriately, and meet the nutritional needs. Water cutting can also be carried out, and the survival rate of water cutting is close to 100 percent. Water cutting is generally carried out around May to June each year. Keep the two leaves at the top of the cutting and insert them into water, pay attention to changing the water to prevent deterioration of water quality from causing the base to rot, and rooting can occur after about 20 days.
4. Points for attention
When cutting the base of the branch, pay attention to doing it in one go to ensure that the wound is smooth, so that it can fully contact the soil, enhance the ability to absorb nutrients, and increase the rooting rate. After cutting, pay attention to doing a good job in temperature management, and the temperature should be kept at about 15 degrees. If the temperature is too high, it will affect the rooting of the cuttings, cause the flower roots to rot, and reduce the survival rate. And keep the soil moist. When the substrate turns white, water it in time to prevent the cuttings from dying due to lack of water, and water is the key to ensuring the normal growth of gardenia. And also pay attention to doing a good job in additional fertilization. The fertilizer is mainly decomposed farmyard manure. Pay attention to the dosage of fertilizer to prevent improper additional fertilization from causing phenomena such as yellowing and blackening of gardenia leaves.
The above is a brief introduction to the cutting method for gardenia. There are many propagation methods for gardenia, and cutting propagation is mainly used for home ornamental propagation.
