Can walnut shells be used as flower soil?

Walnut shells can be used as flower soil. They are rich in potassium, so they can be used as potassium fertilizer. They are of great help to the growth and development of flowers and plants, making them more upright. This fertilizer is relatively clean, but cannot be used directly and needs to be crushed.

How to use walnut shells to grow flowers

1. Burning wood ash

There are several ways to use walnut shells as fertilizer. The fastest way is to burn the walnut shells directly into wood ash. This is because the walnut shells are hard and not easy to rot, and they mature very slowly when buried in the soil. Therefore, burning them directly into wood ash can retain most of the trace elements.

2. Fermentation and maturation

If you don't want to lose the organic matter in the walnuts, you can use a tool such as a hammer to crush the walnuts, then add a small amount of animal manure and appropriate urea, mix them well and let them compost and ferment. Turn them over every 2-3 days. Usually, they will be fully mature after half a month and can be used directly for fertilizer.

3. Bottom maturation

In addition to composting, you can also place walnut shells at the bottom of the potting soil and let the soil mature slowly. The walnut shells will gradually rot and decompose in the soil, so that their nutritional value will not be lost at all. However, it is best to boil the walnut shells to cook off the salt, sugar and other impurities on the outer skin, which can accelerate the decay of the walnut shells.

Precautions for growing flowers with walnut shells

When planting plants in pots, you can spread walnut shells in the pots. This can replace expanded clay and prevent the roots of flowers from rotting. However, walnut shells are hard, so when using them as flower fertilizer, you need to turn the semicircle downwards to prevent the sharp parts from hurting the roots of the flowers.
