How to Propagate Gardenia by Cuttings: A Detailed Guide to the Latest Cutting Method
Gardenia is a flower that everyone is familiar with, and it is distributed very widely in our country. The figure of gardenia can be seen easily in parks in many places. In fact, gardenia is not only for ornamental use, but also has certain edible and medicinal value. There are now many people growing gardenia in our country, and when growing gardenia, its propagation methods mainly include cutting propagation, seed propagation and layering propagation. Today, the editor will introduce the cutting 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 branches directly affects the survival rate and the growth ability after survival. First, we should choose a gardenia tree with a relatively long growth period, robust growth and no previous pests or diseases as the mother plant. Then choose strong-growing, thick branches as cuttings, and do not use branches damaged by pests or diseases. Then cut the branches off from the base, and cut them into cuttings of about 18 cm. Cut the base of the cutting into a slanted 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 necessary to prepare the cutting substrate. Gardenia is suitable for growing in slightly acidic soil, so when choosing the substrate, attention should be paid to the pH. It must not be neutral or slightly alkaline, otherwise the survival rate of the cuttings will be extremely low. Then make sure the substrate is sufficiently fertile, highly permeable and drains and irrigates normally. If it is potted, then attention should be paid to the choice of pot, and the best choice is a ceramic pot, because a ceramic pot has relatively strong permeability, which is beneficial for the cuttings to take root, and the price is relatively affordable, which can reduce planting costs.
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 preparatory work is done, control the cutting density 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, management should be strengthened, and appropriate topdressing should be applied to meet nutritional needs. Water cutting can also be carried out. The survival rate of water cutting is close to 100 percent, and 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 base rot, and roots can form after about 20 days.
4. Precautions
When cutting the base of the branch, pay attention to doing it in one go to ensure the wound is smooth, so that it can fully contact the soil, enhance nutrient absorption capacity, and improve the rooting rate. After cutting, pay attention to temperature management, and the temperature should be kept at about 15 degrees. If the temperature is too high, it will affect rooting of the cuttings, cause flower root rot, and reduce the survival rate. Also keep the soil moist, and water in time after the substrate turns white, to prevent the cuttings from dying due to lack of water, and water is the key to ensuring the normal growth of gardenia. Also pay attention to topdressing, mainly with decomposed farmyard manure, and pay attention to the dosage of fertilizer, to prevent improper topdressing from causing yellowing or blackening of gardenia leaves.
The above is a brief introduction to the gardenia cutting method. There are many propagation methods for gardenia, and cutting propagation is mainly used for home ornamental propagation.
