What Types of Milk To Use for Plant Care?
In the old days, milk was milk. It came from a cow and was enjoyed as a drink or made into butter, cheese, or cream. As time went on, milk was pasteurized, and made into ice cream, dessert treats, and milkshakes. Nowadays, milk can come from cows, goats, sheep, camels (yes, it’s true), and even plants. And it doesn’t end there.
Milk can be skimmed, low-fat, full-fat, powdered, evaporated, fresh or sour. Milk selection is now a minefield, and so the question is, which milk is beneficial for plants?
The Most Popular Choice – Milk That is Good for Plants:
- Fresh cow’s milk (2% low fat).
- Sour milk.
- Evaporated.
- Powdered milk.
- Buttermilk.
- Evaporated milk.
- Almond.
- Soy.
Don’ts – Milk That You Should Not Use:
- Flavored milk.
- Sweetened condensed milk.
- Skim milk.
- Full fat (undiluted).
Not all milk is made equal, and therefore they are not all beneficial to plants. Some types of flavored milk and sweetened condensed milk are high in sugar and are highly processed too. These will have little nutritious value for plants and may attract unwanted pests and problems.
While skim milk can promote the development of black rot and soft rot, the fat in full-fat undiluted milk can damage the plant’s foliage – so it’s really all about balance.
Watering Plants With Milk
Watering plants with milk, aside from providing nutrients like calcium and proteins, can also improve soil health. The beneficial bacteria in milk can help break down organic matter, enhancing soil structure and promoting healthier root growth. This improved soil environment can be particularly advantageous for plants that thrive in well-aerated and nutrient-rich soil. However, it’s crucial to use milk in moderation to prevent negative effects like rot and fungal growth. (Source)
These plants, among others, might benefit more from the soil-enhancing properties of watering with milk:
- Jade Plants: These plants could benefit from the improved soil structure and nutrient availability.
- Begonias: Enhanced soil health might aid in their growth and flowering.
- English Ivy: Beneficial bacteria in the soil could support their root systems and overall health.
- African Violets: Improved soil conditions could lead to healthier growth and blooming.
Milk as Fertilizer
To utilize milk effectively as a fertilizer, it’s recommended to dilute it with water in a ratio of 1 part milk to 9 parts water. This mixture should then be applied to the soil around the plants. This method helps avoid potential issues like odor and mold growth on the foliage. The primary advantages of using milk as a fertilizer include providing essential calcium for plant growth, activating beneficial soil microbes, and offering nutrients like potassium and phosphorus. Additionally, it aids in enhancing plant immunity against various stressors.
These plants typically thrive with the nutrient boost provided by diluted milk used as a fertilizer:
- Leafy vegetables like spinach and kale
- Flowering plants such as roses and tomatoes
- Fruit-bearing plants
How to Clean Plant Leaves With Milk
Cleaning the leaves of your plant with milk is much like foliar feeding. After spraying the leaves with a diluted mixture of milk and water, allow the leaves to absorb the milk for approximately 30 minutes.
Then wipe off the excess milk with a soft, damp cloth. Cleaning the leaves with milk will also protect the leaves from unwanted pests looking for a tasty snack!
Pests such as aphids, thrips, and mealybugs cannot process milk enzymes, which leads to their demise!
