Lu's stone lotus is a kind of small and medium-sized plant, which has a small stem and a small diameter. Its growth rate can be said to be relatively slow, so it does not need to change pots frequently.
The basin changing period of Lu's stone lotus may be several years as it grows. The new basin can be larger. The basin diameter is 1-2 inch larger than the plant diameter, which can promote the plant growth.
Of course, the nutrition in the flower pot is reduced, or you can change the pot by the way when you want to repair roots and change soil.
You can choose spring as the time of basin changing, because spring is the season of basin changing. You can also change pots in autumn.
Basin soil can choose the soil with good permeability, and the soil should be fresh. You can choose to mix peat soil with some cinder particles and add a little river sand.
You can add some basic fertilizer to supplement nutrition.
Do not change pots in hot and rainy seasons. It is difficult to slow down roots and the survival rate will be much lower.
Before changing basin, it can repair roots properly, or cut off the head of the larger plants of the lotus. The cut head can also reproduce well in the soil.
