Golden Bean Orange Tree Stump Planting:

1. Pot soil substrate

Golden Bean likes loose, fertile and well-drained soil, so choose a slightly acidic soil It is appropriate to mix humus soil with weathered pond soil or pastoral soil mixed with sand as the matrix. Cake residue, bone meal, water chestnut slices, and slow-release fertilizer can be appropriately added as the base fertilizer.

2. Watering principles

Keep the pile base moist before germination. In the north, it is best to use bags or plastic wrap to moisturize. After germination, the number of water sprays should be appropriately increased every day. Pay attention to the same Spray, rather than water, the process until the newly erupted leaves and branches have hardened and become strong and new shoots are no longer growing.

Within one month after potting, the branches and leaves should be sprayed with water frequently to keep the pot soil moist and properly shaded. After the tree stump regains its vitality, you can gradually switch to normal watering. The principle of water management is "when it is dry, it is wet, and when it is dry, it is wet." Golden bean bonsai will easily die if it is too dry.

3. Fertilization measures

Fertilization cannot be applied to plants that have just been potted. After normal growth, if the pot soil is fertile and has base fertilizer, there is no need to topdress. If the pot soil has poor fertility, , you can lightly apply some quick-acting compound fertilizers as appropriate. Generally, more than 10 grains of compound fertilizer can be applied to a flowerpot with a pot diameter of 25cm.

Golden beans are good fertilizers and should be applied lightly and frequently. Fertilizers are mainly phosphorus and potash, such as chicken, duck manure or fishy water. Apply once every 7 to 10 days in spring and autumn. During the rainy season, some cake fertilizer can be spread on the pot surface. During the flowering period, less or no fertilizer should be applied. After the fruit has settled firmly, apply light fertilizer twice.

4. Pruning and shaping

Golden beans are mostly pruned and rarely climbed. This is usually done in early spring from February to March. Mainly prune off dead and weak branches, overlapping branches, crossing branches and diseased and insect-infested branches. According to the tree shape, the principle of weak pruning for strong branches and strong pruning for weak branches can be adopted to shorten the main branches, generally leaving 4 to 5 inches on the strong branches. Leave 2 to 3 buds on thin and weak branches, and prune off the rest.

After new shoots sprout, branches that are too dense and disturb the shape of the tree should be removed as soon as possible. The bean shape should be simple and should not be too complicated. The main tree shapes include straight trunk type, diagonal trunk type, etc., and are generally pruned into a natural large tree shape or semi-circular spherical shape.

5. Prevention and control of diseases and insect pests

The main diseases of golden beans are black mold. You can spray Bordeaux liquid or use 5% alcohol to wipe away the mold; the main pests are scale insects. You can spray 40% omethoate solution 1000 times or use a small brush or knife to remove the insects.
