Cultivation methods and precautions of potted Sophora japonica

How to cultivate Sophora japonica

sowing

The Sophora japonica tree looks tall and big, but it can actually be propagated by seeds. Choose mature and plump seeds, soak them in warm water for 24 hours, take them out and mix them in 2 to 3 times the amount of fine sand, then place them in an environment of about 20℃ for germination. During the germination process, the seeds should be frequently fanned to ensure that the temperature above and below the seeds is consistent. Once the seeds germinate, they can be planted. It should be noted that Sophora japonica has a long root system, so you need to choose a larger and deeper flowerpot. It is best to plant it in the open field as it grows faster. Wait until it grows into a small plant before transplanting it into a pot.

Thinning

When the plant grows to 10~15 cm in the year of sowing, it can be planted in a pot. Choose a deeper pot and ensure sufficient sunlight. For some weak seedlings, they can be removed directly.

Fertilization

Adequate nutrients are helpful to the growth of Sophora japonica. During the growth period of Sophora japonica, sprinkle some granular fertilizer around the potting soil, and then water it, or directly irrigate with fertilizer water. For smaller flowerpots, water and loosen the soil in time after fertilizing. Fertilizers commonly used in households include bean cakes, horseshoe slices, and sheep horns, which are fermented before use.

prune

The growth rate of Sophora japonica is moderate, and topping should be carried out in time during the growth period of seedlings to promote branching. Some aging and yellowing branches and leaves should be pruned off in time.

Precautions for cultivating Sophora japonica

Timely weeding

Perhaps because Sophora japonica is very inclusive, many weeds will grow around it. The same applies to potted plants. It is recommended not to use herbicides, which will have a certain impact on the growth of Sophora japonica. Manually loosen the soil and weed, removing the grass by the roots.

prune

Timely pruning helps ensure the perfect shape of the Sophora japonica tree. Another very important point is that the potted Sophora japonica can be dwarfed through pruning to promote branching so that each branch is full of flowers.
