Some gardeners use milk and kefir as plant food and don’t see anything wrong with it.
However, experts say this is not the best solution.
We'll tell you what will happen if you feed plants with milk or kefir.
Why You Shouldn't Feed Plants with Milk
Firstly, using milk or kefir as fertilizer can lead to the appearance of a persistent unpleasant odor in the greenhouse.
Secondly, milk-based fertilizers can provoke the proliferation of sciarids and other pests.
In addition, by feeding plants with milk, you provide a food source for milkworms (enchytraeus).
If you don’t want to see swarms of worms swarming around your garden, it’s best to avoid milk-based fertilizers.
