If you want to plant your garden in May, you don't necessarily have to buy new soil. With a few tricks, the soil from the previous year can be prepared again.
The old soil can be mixed with fresh potting soil in a one-to-one ratio, this variant benefits from additional fertilization - for this you can use coffee grounds. It is not always possible to recycle last year's soil – it can be composted, so it becomes nutrient-rich soil for the next year.
