Can honeycomb coal be used as flower soil?

Honeycomb coal can be used as flower soil, which can increase the looseness and air permeability of the soil. Honeycomb coal slag contains trace elements, which the roots of plants can absorb and grow stronger. However, it cannot be used directly and needs to be soaked before use. Otherwise, the alkaline or harmful substances contained in it will damage the plant roots.

How to use honeycomb coal to grow flowers

1. There is soil in the honeycomb coal. If you break it directly, there will be a lot of dust inside. You can soak the honeycomb coal slag before breaking it. If the container is small and cannot hold too large pieces of honeycomb coal slag, you can break it first and then soak it. Basically, it can be used after soaking for 7 days.

2. Break the soaked honeycomb coal slag into pieces, wash off the dust, and then screen the fragments of different sizes. The smaller parts can be used as flower soil, the larger parts can be used to pad the bottom of the pot, and the medium particles can be used as paving.

Precautions for growing flowers with honeycomb coal

1. After the honeycomb coal slag is broken, there will still be soil residue inside. When planting in potted plants, it is best to wash it and leave only the broken particles. Mixing it with other media to prepare the soil can increase the air permeability of the soil. If it is used to plant plants in the ground, it does not need to be washed and can be planted directly.

2. When using honeycomb coal as flower fertilizer, do not use it alone. The trace elements it contains are relatively few and cannot meet the growth needs of the root system. Therefore, you can combine it with Akadama soil, leaf mold and other materials, and the plants will grow more vigorously.
