First, the problem of changing potted elm bonsai

1. How often does the elm bonsai change pots? Do I need to wash my roots to change pots?

Generally speaking, the pots of elm bonsai should be changed every two to three years. The reason is that after two to three years of elm cultivation, the nutrients in the basin soil are almost exhausted, and watering and fertilization may make the soil slightly alkaline, which will directly affect the growth of elm bonsai. At this time, in order to improve this situation, it is necessary to change the pot.

When changing pots, in addition to replacing nutritious plants, we should also pay attention to pruning the rotten roots produced in the growth process, removing some germs and eggs that may remain in the roots, and removing the salt that appears in the management process. At this time, the key operation of changing pots is root washing. The so-called root washing refers to carefully removing the old soil with some hard objects such as bamboo sticks, and then washing it with running water until all the soil is cleaned and the complete root system is exposed. At this time, we can cut off the messy roots and rotten roots with scissors, which is convenient for modeling the roots. If you like bonsai with stones, you can also take the opportunity to deal with it and wash away eggs and salt at the same time, so as to kill two birds with one stone.

Generally, after root washing and pruning, it can stimulate the elm bonsai to emit more and more developed roots, and the replaced soil can continuously provide nutrients for the growth of elm, which is of great significance to the strength and graceful posture of elm.

2. When should the elm be changed to wash its roots?

We all know the significance of changing pots and washing roots of elm trees. Let's talk about the pot changing time of elm bonsai first. Generally speaking, the time to change pots should wait until the elm tree enters dormancy. When the elm enters the dormant period, the sap flows slowly, which is less harmful to the elm, and the evaporation of the elm during the dormant period is also relatively small, which is very beneficial to the elm basin.

Judging from the dormancy time of elm, the season is roughly between winter and spring. Generally speaking, it marks that the elm goes into dormancy. When it enters dormancy, most elm leaves will turn yellow and begin to fall off, and its bud point will be more obvious. This time means that the elm begins to sleep, and then we can change pots and wash roots. Don't change pots too early, don't sleep completely too early, and don't be too late, which will affect the effect of changing pots and even cause the death of elm bonsai. Be careful. )

3. How to operate the elm after changing pots and washing roots? How to serve?

This operation is of great significance to the survival and health after changing pots, which can not be ignored.

After root washing and pruning, elm trees should be put into pots. Elm likes a loose and breathable growth environment, so potted soil should meet the growth requirements of elm. It is best to use loose and breathable river-sand mixed garden soil and some humus soil for soil preparation. At the same time, the bottom of the flowerpot can be covered with stones or broken willow bark. , make the ventilation and drainage better, and the roots are not easy to rot.
