Welcome back green thumb lovers! Maybe some of you don’t know that milk (especially cow’s milk) if used correctly on plants can be an amazing ally.

In fact, milk can make plants grow and flourish thanks to its nutrients and can be used for garden, orchard and house plants.

Let’s look specifically at the reasons why we should use it.


Milk in the plants, the farmers’ trick is truly extraordinary


Milk can be a very good liquid fertilizer. In fact we just have to add it to our organic fertilizer. Warning: it is important to remember that expired milk can be safely used.

Disinfect and clean work tools

If not properly cleaned our tools can make plants sick through the attack of some parasites. What we have to do is very simple: we just need to dip a cotton ball in the milk and pass it on the tools after using them. They will be best disinfected and we will be able to use them without fear.


Milk can become an exceptional natural fertilizer. All we have to do is pour some into the watering can so that we get 80% water and the rest milk. However, the plants must be watered with milk once a month, at most two.

Fungicide and gives protection from insects and parasites

Milk contains antibacterial and fungicidal properties. In addition to this, it can protect against whiteflies, red spiders and aphids. In short, it protects the plant in a natural way.

If we have a plant that has already been attacked by fungi we must use a mixture containing sodium bicarbonate. We must pour 20 grams of sodium bicarbonate into a spray bottle containing one liter of water and ¼ liter of milk. Shake well to dissolve the bicarbonate and then spray it on the darker areas once a week.

However, if we want to prevent this problem we must pour 10 parts of water into a liter of milk. Then we must transfer the result into a spray bottle and wet the stem and leaves. You must carry out this operation once a month and do not water the plant for the following 24 hours.

Ph of the soil

With a plant that needs alkaline soil we must necessarily use milk. This is important because the calcium in milk reduces the acidity of the soil. Simply pour a spoonful of powdered milk into a liter of milk. Then we mix and pour the result into the soil.

Cleans the leaves

The leaves need to be cleaned often due to the dirt that inevitably accumulates on them every day. This clogs the pores and the plant has difficulty breathing. Therefore, simply wet a cloth with a little water and pass it over the leaves. After this operation we will be able to admire bright and clean leaves.

I’d say there’s nothing left to do but get to work!
