How to propagate hydrangeas: propagation methods and maintenance skills for hydrangeas.

How to propagate hydrangeasA comprehensive introduction to how to propagate hydrangeas, including the propagation methods and cultivation skills related to hydrangea planting, details are as follows:Hydrangeas are very beautiful flowers, named for their resemblance to a silk ball, and are loved by many people. However, when cultivating hydrangeas, people often don't know how to propagate them. So, even if they want to grow more hydrangeas, they have to buy them from the market. In fact, the cutting method for propagating hydrangeas is very simple. Let's find out more about it with the editor.[One, how to propagate hydrangeas]1. Division propagationThere are four methods of propagating hydrangeas, with division propagation being one of the more successful and simpler methods. However, the division should be scheduled before the early spring germination. Separate the rooted plants from the mother plant and directly plant them in pots. Do not water excessively and keep them in a semi-shaded area. After new buds emerge, transfer them to normal management.2. Layering propagationThis propagation method is even simpler. Those who have done layering propagation with related plants will generally know how to operate it. The success rate of layering propagation is close to 100%, but the drawback is that it takes longer. Patience is needed during the cultivation process, otherwise, the hydrangeas may wither and die.3. Tissue culture propagationUsing dormant buds as the external explants, after routine disinfection, they are inoculated on MS medium supplemented with 0.8 mg/L 6-benzylaminopurine or 2 mg/L indole acetic acid to induce adventitious buds. When the seedlings reach 2-3 cm tall, they are transferred to a 1/2 MS medium supplemented with 2 mg/L indole acetic acid to grow into complete small plants.[Two, the cutting method for propagating hydrangeas]How to propagate hydrangeasWhen propagating hydrangeas through cuttings, since it is a branch cutting, the branches need to be treated first. When selecting branches, choose healthy ones and cut them with a knife, making sure the cut surface is smooth and preferably at a 45-degree angle. The remaining leaves should also be cut back, preferably by half.This reduces moisture evaporation during propagation and makes it easier for the plant to survive. Prepare the soil, usually a loose and fertile sandy soil is chosen, then insert the treated branches, making sure to disinfect them with a multi-jinling fungicide. After insertion, regularly spray water to keep the soil moist, and the hydrangea branches will root and sprout in no time.[Three, post-cutting care techniques for hydrangeas]Spray water after each cutting of the young shoots, preferably with a small spray bottle to avoid overwatering. Place the potted plants in a bright area without direct sunlight, keeping the temperature between 15-25°C, and spray water twice a day, in the morning and evening. When the sun is strong, spray water around the plant to ensure a good germination humidity.
