How to feed blood to plants?

There is no need to bring blood to raise flowers! There are several reasons! Blood contains a lot of salt, which will lead to dehydration and death of flowers. Second, blood flowing into the soil will cause soil board connection, which is not conducive to root ventilation and will naturally die! Third, the nutrient flowers in the blood can't be absorbed directly, but can only be decomposed! With only blood, it will produce a lot of heat when rotting, which will burn the roots and kill the flowers! If the landlord must use blood to raise flowers, I will give some advice! Mix a handful of blood with water to dilute the salt! Pour water the next day after pouring blood to get the salt out! You can also raise some fungi! Saprophase is a good choice.
