Vitax Dried Blood 900g (box)

Rich in nitrogen, Dried Blood is completely organic and promotes above-the-ground growth and healthy foliage.
Fast-acting, Dried Blood makes an excellent top dressing for foliage plants in the greenhouse or conservatory.
Dried Blood should be applied monthly during the growing season, lightly forked in and watered.
Adding Dried Blood to the soil will increase nitrogen levels to improve the growth of vigorous, healthy plants.
Dried Blood can also help raise the acid level of the soil. Many gardeners prefer to add Dried Blood to the soil to raise nitrogen levels which have been lost through multiple plantings.
Always read the instructions for correct application rates as too much Dried Blood can raise nitrogen levels too much, which can hurt plants.
During application, ensure Dried Blood does not remain on leaves or stems.
