Milk can be a perfect fertilizer because it feeds plants with calcium, makes them virus and disease resistant. Milk contains beneficial proteins, vitamin B and sugars that are good for plants, improving their overall health and crop yields. You can use fresh milk, evaporated milk, or even powdered milk as well but you should always dilute it with water half-and-half. There are two basic ways to fertilize with milk.
- Milk spray. Make a solution, put it into a spray bottle and apply to plant leaves. Distribute about 5 gallons of milk per acre, allow the milk to soak into the leaves and ground. Repeat every few months, or spray once at the beginning of the growing season and again during mid-season.
- Milk root fertilization. Pour the milk mixture around the base of the plants where the roots will gradually absorb the milk.
