Longevity flower is the most prone to root rot and black rot, and it is afraid of water accumulation. Usually, when we are preparing soil, the permeability and permeability of sand are very good, which can prevent water accumulation and root rot, and also prevent root rot.
This kind of corncob is cut into small pieces with scissors, which is not more than one or two centimeters, and the effect will be poor. Cut into sections or cut in half, the number does not need to be large.
Then find a flowerpot and put the corncob in the flowerpot. The bottom of the flowerpot is like this, just spread a thin layer of two or three centimeters thick.
After that, we can fill the soil and plant flowers. Spreading a thin layer of bottom can play a role in water and air permeability, prevent water from accumulating at the bottom of the basin, prevent water from draining out of the flowerpot, and increase the air permeability and drainage of the soil in the flowerpot. Then the root system of this longevity flower is not easy to accumulate water, rot and rot.
If you really don't have corncob at home, you can also use large-grained stones, such as weathered volcanic rocks, and some coarse river sand with good water permeability, and lay it at the bottom of the flowerpot as the bottom.
