Gibberellin, that is, 920, depends on the aging degree of the stem when used. In case of severe aging, the concentration should be appropriately increased, which is generally about 65,438+0,000 times. After alcoholization, dilute it with water, and apply it evenly to the place where branches are needed with a bristle brush, once a day, two or three times is enough.

Extended data:

Boxwood avoids strong light, so it is only suitable for astigmatism when planting, not for strong light irradiation. Boxwood that has just gone down the mountain or been transported for a long time and just turned over should be kept in the shade for a period of time before being transferred to normal maintenance. Very dilute nitrogen fertilizer (2000 times urea diluent) can be sprayed throughout the year, and contact with phosphate fertilizer and potash fertilizer is prohibited.

You can also add a small amount of nitrogen fertilizer when watering, so that the leaves are very beautiful, dark green and shiny.

Boxwood pruning time:

Boxwood is resistant to pruning and has strong germination ability. Pruning can stimulate plant lateral buds to sprout new buds. But the pruning time of different parts of boxwood is different. The top branches should be pruned when the new buds sprout, and should not be pruned again. It is recommended to keep two-thirds of the branches.

If it withers, it will be difficult for the old branches to grow new leaves. Trunks and branches are pruned during winter dormancy. During this period, the trunk stores enough nutrients, and generally sprouts in the next spring. If the trunk and branches of plants are cut off after germination, it will be difficult to germinate. Some will not germinate even for a year or so.
