Throwing away the old potting soil after repotting is too wasteful; simply process it into new nutrient soil

Many people have asked the editor whether the old potting soil removed from flowers can still be used. Here the editor gives a brief answer: if it has not been processed, it generally has little nutrition left. The nutrients in the potting soil have been used up, so in theory it is not really suitable for continued use, but after processing it is different.

Method for processing old soil into nutrient soil

First, we need to prepare some worm castings, ratio: 1/3. Worm castings are a very good organic fertilizer and can play a better role in improving the soil and building fertility.

Then mix in some leaf mold, plant ash, etc. If the aeration is poor, add some perlite and vermiculite. The ratio depends on the flowers you are growing.

With just this simple processing, the new nutrient soil is ready.

Things to note when changing potting soil

1. When changing the soil, keep as much soil around the roots as possible; do not bare-root them;

2. Soil changes should not be carried out continuously within a short period. For most plants, changing the soil once every six months or more is fine.

3. When changing the soil, if the root hairs are damaged, remember to simply treat the wounds before planting them back

4. Flowers must not have their soil changed while they are blooming
