Yes, says botanist James Wong, but why would you want to use it?

Milk is a rich source of protein, which contains nitrogen – a key plant nutrient needed for healthy leaves. However, the same could be said for almost any organic material, plant or animal. The nitrogen in milk is also only available after decomposition by bacteria and fungi in soil. Not only are these microbes often not present in potting mix for houseplants, but when they are, they produce an almighty odour. Plus, milk is far more expensive per litre than store-bought houseplant food, so it will end up delivering fewer nutrients, in a less accessible form, with a more-than-pungent aroma.
