Milk isn't just for food. Here are 7 reasons to use it in your garden

There are two universal truths of which I've been pretty confident of for... pretty much forever. Cats like milk and plants only like water. I was a bit wrong on both accounts. While plants need water to survive, they also like milk. (Also, most cats are actually lactose intolerant so kittens over 12 weeks, should just be sipping water, according to Science Focus).
According to numerous sources, including Gardening Know How, milk can actually benefit your garden and the plants. Want to know why? Keep reading.
1. Milk acts as a fertilizer
The calcium in milk can help strengthen the structure of a plant. The nourishing properties that animals and people get from milk actually help protect plants too. The sugars in the milk can help yield healthier crops, according to Gardening Know How.
2. Milk can disinfect
When milk is applied in areas with direct sunlight the milk takes on antiseptic-like properties. The Cape Gazette recommends dipping your garden pruners in milk to disinfect them instead of bleach (no promises on how that's going to smell in a few days...).
3. Milk can prevent fungus
Fight fungus disease (like mold or rot) by applying watered-down milk to the surface of the plants. For the most success, combine 1 part milk to 2 or 3 parts water. You should spray this mixture on the leaves of your plants every 10 days. For the best results, use this at the beginning of the season as a preventative measure, according to The Spruce.
4. Milk improves the health of your soil
Using milk in your soil or compost pile can make the soil healthier because the soil absorbs the fats and vitamins inside the milk. Some people opt to pour powdered milk directly into the soil, but you can also do a watered-down mixture, which should help keep funky smells away.
5. Protect your tomatoes
If you'd like to protect your tomatoes from rot and disease, try mixing 1 part skim milk with 9 parts water. Spray your plant every few weeks (until the middle of summer) to keep diseases away from your tomatoes, according to Harvest to Table.
6. Milk can deter some insects
When applied properly, cows milk can deter some bugs like aphids, thrips, and mites. You'll need to use whole milk to maximize on this perk though, according to a study published in the Journal of Eco-friendly Agriculture.
7. Milk and Molasses
While milk works wonders in the garden, you can amp the power of this garden friend by mixing in molasses. The combination of milk and molasses amps up needed sugars (that help the plants stay strong) and the mixture will keep weeds away because the combination makes soil conditions unfavorable for weed seeds, according to Mother Earth News
If you're worried about the odor, a mixture of two parts water, one part milk still provides the healthy benefits of milk but helps the odor or rotting milk dissipate faster.
