How to Make Organic Fertilizer Safe and Highly Effective

It is best not to use chemical fertilizers; because of their high inorganic salt content, if they are not diluted enough they can easily burn the roots. Organic fertilizer is relatively safe and reliable. At the same time, its fertilizing effect lasts a long time and it can improve the soil. Take 5 parts rapeseed cake (half of the total), 3 parts bone meal, and 2 parts plant ash, mix and stir them well, put the mixture in a vat, add water in several rounds to soak and swell it, seal it for fermentation, and after one year divide it into small pieces and sun-dry them, then place them around the rim of the pot surface; as you water, the fertilizer dissolves and enters the soil, and it can be applied all year round, but for small potsorchidsit cannot be used during the budding period, because when watering it is easy for the lump fertilizer to be washed into the middle of the new leaf cluster and damage the new shoots. The mixed fertilizer can be diluted with water 30-50 times to make a light liquid fertilizer and applied to the soil in several rounds during the growing period; no fertilizer is needed during the high-temperature summer season. For solid-color orchid varieties, after September apply the extract of plant ash 1-2 times, and the effect is very good. Fertilizing should preferably be done in the evening, and the next morning water once. (Jiangcheng, Zhejiang)
