Advantages and disadvantages of coarse sand flowerpot

Because of the large gap between coarse sand and flowerpot, it can increase the natural permeability and air permeability of soil, which is beneficial to the drainage and air permeability of plant roots and help them grow better.

Most of plant deaths are caused by root rot caused by long-term water accumulation in roots, while the sandy flower soil has good drainage, even if it is watered more, it can be naturally discharged from the soil, and it will not accumulate in the flower soil to affect the growth of plant roots, so that plants can avoid root rot caused by water accumulation in roots to a great extent, thus allowing plants to grow healthily.

Disadvantages: Too large coarse sand will cause too many gaps in the basin soil, which will be unfavorable to the rooting and growth of plants. It is even easy to let the roots of plants leave the soil, which is not good for the growth and development of plant roots. Generally, coarse sand particles that are too large are only suitable for laying or padding on the bottom of the basin to filter water.

How to use coarse sand?

Coarse sand should be mixed with humus and base fertilizer in the ratio of 1: 1: 1. For plants with high drainage requirements, such as succulents, the proportion of coarse sand can be appropriately increased, which is more conducive to plant growth.

Generally speaking, coarse sand does not need special treatment before mixing with flower soil, but for plants whose roots are easily infected by bacteria or damaged, it is best to disinfect coarse sand, such as drying in the sun or spraying carbendazim solution.

Generally speaking, coarse sand is a good flower soil matrix, which can greatly increase the drainage capacity and permeability of flower soil and make the plant roots grow better!
