1, propagation of transplanted seedlings

To make bonsai, forsythia suspensa must first cultivate transplanted seedlings; There are four propagation methods of transplanted forsythia suspensa seedlings: sowing, cutting, layering and branching. These four methods are the most commonly used. Transplanted seedlings should be planted in soil pots for 2-3 years after cultivation. In this period, the branches of Forsythia suspensa can be made thicker and stronger, and the branches of Forsythia suspensa in the growing period are softer, so that Forsythia suspensa can be preliminarily shaped.

2. Transplanting in pots

After a period of cultivation, forsythia suspensa can be transplanted before it is officially put into the pot in early spring; Before, the plant should be roughly pruned, some useless old branches and weak branches should be cut off, and then the embryo should be cultivated in a larger flowerpot; Loose and breathable sandy loam should be selected as basin soil, which is beneficial to nutrient absorption and permeability of root system. After transplanting, water should be poured enough, and then it should be maintained in a sunny and ventilated place.

3. Maintenance in growth period

After the transplanted forsythia suspensa survives, it is necessary to control the water content and ensure the principle of "not drying, but pouring thoroughly". If the pot soil is too dry, the flowering period of forsythia suspensa will be less and dry. However, if you water too much, it will also cause water accumulation, which can't shoot out of the pot, leading to flooding, which will seriously lead to the death of the whole seedling. The seedlings of forsythia suspensa in the growing period should sprout properly and cut off the redundant branches, which plays an important role in the future modeling.

4. Maintenance of modeling

The common shapes of forsythia suspensa are curved dry type, inclined dry type and cliff type. When climbing a mountain, the trunk doesn't need to be trimmed too much. In the growing period, it is necessary to remove the core of forsythia suspensa, control the growth of branches, trim unnecessary branches in time, and make its lateral branches grow, which can form a beautiful shape and a large and lush crown. Then in summer, you can climb and bind according to the ideal shape to adjust the posture of the tree.
