    Milk has a lot of uses in the garden and can replace more than one product for their care and cultivation, if you know how to use it. And we don't mean milk in a carton, but real milk, possibly pasteurized milk sold in bottles. Learn how to use milk in the garden and start using it today.

    #1 Using Milk in the Garden as a Fertilizer for Plants


    We will start with skim milk watering fertilizer without preservatives. First of all, it is recommended for potted plants and vegetable crops. It is best to use milk "straight from the cows", of course. From the milk available in stores, you can use a pasteurized product. Most often such milks come in bottles and stand in refrigerators. (Do not use UHT milk from a carton!)

    Milk provides calcium, which is essential for plants, and the sugars in milk allow for a better crop. The leaves of the plants will be better colored, will not yellow and fall off.

    Use milk with water once a month, such as rinsing the milk bottle with water. This amount of fertilizer from milk is enough for plants. Calcium affects the reaction of water, so use such a fertilizer for plants that tolerate alkaline, or possibly neutral, soil.

    For potted plants, milk fertilizer is especially suitable for ficus, ivy, aloe, sansevieria….

    #2 How to Use Milk in the Garden to Protect Against Fungal and Viral Diseases.

    Milk contains lactoferrin, which has bactericidal and fungicidal effects. If anything starts to happen worryingly to the leaves of your plants, spray them with a milk preparation. Combine 1 part milk with 2-3 parts water and spray the plant leaves every 10 days. The leaves and the entire above-ground part of the plant should be sprayed.

    #3 Milk for Disinfection

    You don't need to use chemical bleach to disinfect your gardening equipment. Instead, use milk to disinfect gardening tools. Secateurs , or scissors dipped in milk, will not transmit viruses and will not rust as quickly!

    #4 Milk and Pests

    How to use milk in the garden for pests? Milk acts as a repellent against some of them, such as centipedes, aphids, thrips and mites. Mix 1 part milk with 10 parts water and spray the plant's leaves on both sides 1 per week.

    #5 Milk and Soil Quality

    Pouring milk into the soil or compost enriches it with fat and calcium. However, it is better to "water" the soil with diluted milk if you do not want to have an unpleasant smell in the garden.

    #6 Use of Milk in the Garden to Protect Tomatoes.


    The use of milk in the garden works well for growing tomatoes. Milk protects tomatoes from rot and diseases and pests. It effectively prevents potato blight if you make a spray of milk thoroughly on the entire plant. Mix 1 part milk with 5 parts water and spray the tomatoes every couple of weeks, and even weekly in June, July and August.

    #7 Milk and Weeds

    If you add molasses to the milk, it will increase the amount of sugars and prevent the growth of weeds. Then it's enough to use sweet milk to water the weeds once a week.


    • Too much milk can harm plants, as plant roots will suffocate if you water too much or don't dilute the milk.
    • Avoid splashing houseplants with milk in hot weather, because as it turns sour, there will be an unpleasant smell in the room.
    • For vegetables and garden plants, using milk as a spray on the leaves should be done in the morning or evening and only on rain-free days!
