It’s important to be frugal when it comes to using milk, because overwatering your plants with milk can cause the plant to wilt or become stunted. It is always recommended to use whole milk instead of skim, as skim milk can lead to black mold or downy mildew depending on the plants you are watering with.
Finally, because it is milk, it can have a slightly unpleasant smell when placed in the garden!
How to water your plants with milk
Technically any animal milk (cow, sheep, goat, etc.) can be used in the garden. This includes fresh, expired, evaporated, and even powdered milk.
Of course, alternative milks like almond and oat don’t have the same nutritional benefits, so cucumber and basil won’t be as beneficial!
Low-fat or low-fat animal milk options are recommended, as they are less likely to have negative results.
All of these milks must be diluted properly to avoid wilting or rotting on your plants. The best way to do this is to mix milk with water in a 1:1 ratio. Using a spray bottle will help direct the milk mixture directly to the soil and roots.
Alternatively, spray the mixture directly on the leaves, as they can absorb calcium. Spray a small amount on each leaf and wait 30 minutes until the liquid is absorbed.
If there is any leftover milk mixture, simply wipe it off with a damp cloth. Leaving extra liquid on the leaves can cause mold to form, so be vigilant when spraying!
After applying the milk mixture, be sure to avoid using pesticides in your garden. Pesticides will rid the milk mixture of any good bacteria in it, rendering the entire application pointless.
