If there is no pot change for a long time, the old roots in the pot will grow more intensively, which will affect the growth of new roots. Just fall is a good time for basin changing. You can choose to trim the old roots and replace the basin soil at this time, which will make the plants grow better.
Before changing pots, stop water first, then take out the plants, clean up the old soil outside, trim the old and withered roots, replace with new pots of soil, and replant.
Its flowering period is generally from September to October, so in autumn, it is just the time to supply flowers with nutrients. At this time, some fertilizer with high content of P and k elements can be applied appropriately, which can promote the opening of plants and flowers, otherwise, it will cause weak growth and less flowering.
In the maintenance of plants, the problem of watering is also more important. It is not allowed to not water for a long time, so that the basin is too dry, or too much watering, resulting in water accumulation in the basin. Water every 3 to 4 days. When you water next time, you must make sure that the soil in the basin is very dry.
