There are different ways to use milk in your garden, and your plants stand to benefit from each method. Keep reading the article as we will guide you on how to use milk in your garden.

How To Use Milk for Your Plants In Different Methods?

To use milk for your plants in different methods, you can use it as a foliar fertilizer, and you can also use it as a seed starter. In addition, you can make compost out of it, and lastly, you can also use it as a regular fertilizer.

– As Foliar Fertilizer

Milk is a liquid and has some readily available nutrients for your plants. If your plants have a nutrient deficiency, or you just need an easy way to use milk in your garden, use milk as a foliar spray. Milk as a foliar spray is completely safe when you use it correctly. It will supply the leaves of your plants with nitrogen and calcium.Foliar Fertilizer for Plants

To make milk good for your plants, you may need to dilute it, as the excess of it can also lead to problems such as pest attacks later. Also, you have to use a sterilized spray bottle, and this would be faster to target the leaves.

Some benefits of milk for plants are supplying your plants with nitrogen, calcium, iron, and every nutrient needed by the plants, preventing some pests such as powdery mildew from attacking your plants, and preventing blossom end rot in fruits. Milk can help prevent nutrient deficiency.

Blossom end rot in fruits occurs when the plant lacks some nutrients such as calcium. Using milk for plants will enrich the plants with calcium. While this cannot cure the already-sick fruits, it will prevent other fruits from getting the disease. Milk will also help your crops grow super productively.

– As a Seed Starter

The rate of plant growth is significantly higher if the seeds start in a nutrient-rich environment. Starting your seeds in milk—a media rich in nitrogen and other nutrients—is just the boost that your plants need to be super productive throughout the growing season.

Seed starting with milk is very easy, and you just need to soak the seeds with it. Note that soaking seeds in milk as a seed starter is unsuitable for every seed, especially with hard shells. You can always enrich your potting mix with milk and start the seeds using that media.

– To Make Compost

Of course, you can use milk for composting. Remember that the process of composting is only complete with the addition of nitrogen and carbon sources. If you have a lot of carbon-rich ingredients such as hay, brown leaves, and paper in the compost pile, you can add milk regularly to the compost to create a fine and almost perfect product.Making Compost with Milk

Compost made with milk will finish faster, as milk gives a lot of energy to the decomposing microbes. With milk in your compost pile, you will quickly get the best type of compost you may ever use.

Moreover, you can use spoiled milk for plants. The milk may be spoiled for you, but it is becoming more suitable for plants. Remember that plants can only collect decomposed nutrients from milk, so spoiled milk, which is decomposing, has more nutrients for plants.

You no longer need to ask, “Can you put spoiled milk on plants?”; the answer is affirmative. This is due to the fact that as long as there are no toxic products or chemicals in the milk, it is safe for your plants. Plants grow faster when you give them products with readily available nutrients, so spoiled milk can help boost the growth of your plants.

– As a Regular Fertilizer

If you want to avoid making any outcome with milk and just want to use it as fast as you may, as it is an easy approach as well because you just need to pour the milk on the soil, just like when watering plants. This is the most basic application of milk in the garden because this is a safe process, and it is guaranteed to work, just like regular fertilizer.

If you like, you can feed milk to your plants directly. You do not need to dilute it or make any products with it. However, it is always a keen practice to dilute milk. To feed milk directly to your plants, pour it on the soil around the roots of your plants.

If the milk is spoiled, filter out the lumps so that they do not make your garden an eyesore. Also, sweep out every unabsorbed particle in the milk from the soil. You can continually feed your plants with milk. Instead of disposing of your spoiled milk, give them to the plants in your garden.

How To Make Foliar Fertilizer With Milk in Three Steps?

To make foliar fertilizer with milk in three steps, you must dilute the milk and then spray them on the leaves in the morning time. After doing so, you must try to wipe the leaves with a dry cloth if there is any residue left.

1. Dilute the Milk

You can use milk directly on the leaves of plants. However, it can expose the plants to pest attacks. To prevent this, you must mix it with some water, and dilute the milk so that you do not use a heavy amount of it at once. Mix one-part milk with nine-part water in a spray bottle; however, if the product does not look good enough, reduce the volume of water used.

2. Spray the Leaves

Pour your diluted milk into a spray bottle, then water plants in your garden with it. Spray the leaves and make sure that every leaf gets some droplets. If some plants have calcium deficiency, concentrate on those plants when misting the garden.

Spray the leaves early in the morning so that they can get dry quickly. Do not spray them at night. Also, stop spraying the leaves before droplets start dripping off them.

Milk-fed plants may look sick because you overwater them with milk, so measure the irrigation. You may also have used a bad product of milk for them. Do not use sweetened or flavored milk for your plants, as such a product has extra ingredients that might attract harmful microbes to the garden.

3. Wipe the Leaves

If the leaves are still wet after 30 to 45 minutes, use a drop cloth to dry them. Leaving a nutrient-rich solution on the leaves of your plant can attract pests such as insects and microbes, and these pests can be disastrous to your plants. This is the main reason that you only want to keep spraying the leaves once they start dripping. Also, do not forcefully wipe the leaves with a dry cloth so that you do not harm them.

Just as in the case of water, if you give your plants more milk than they need and the milk does not drain quickly, you may be exposing the plants to root rot. This can be disastrous and can even kill your plants. Ensure that your plants and the soil surface are dry after using milk for the plants.

How To Start Seeds With Milk in Three Steps?

To start seeds with milk in three steps, you must first prepare and dilute the milk. Then, you should try to soak the seeds in the mix you made, and after doing so, you can plant the seeds at the right temperature.Soaking Seeds in Milk

1. Prepare the Milk

To soak seeds in milk, dilute the milk first. Mix one-part milk with two or three-part water to create a good solution for your seeds. Also, remove every floating or unwanted particle from the milk so that when you put your seeds, only the seeds will be in the solution.

2. Soak the Seeds

It is time to soak the seeds. Soak them overnight so that the milk can penetrate their shells. When the seeds germinate, the nutrient-rich milk will be their first source of nutrients. This can help them to grow quickly.

3. Plant the Seeds

After 12 or more hours of soaking the seeds, plant them in a seed tray. Plant them in the morning when the temperature and light are just right. You may opt to add some milk droplets to the potting mix to make it more nutritious. If you are growing plants with soft seeds, such as beans, pepper, and tomato plants, do not add more milk to the substrate; yet again, soaking them is enough.

How To Make Compost With Milk To Benefit Plants?

To make compost with milk to benefit plants, you must gather the compost pile with greens and browns, and then you can water the pile with some milk using the right amount, and lastly, you should stop using it after two months.

1. Gather the Compost Pile

Start by gathering all the materials that you want to break down to form your compost. Gather greens and browns to make the pile complete. You will be using milk as a water and nitrogen source, so gather more browns than green.

If you like—or depending on how much milk you have—you can use only browns, such as hay, in your compost pile. Just keep in mind that the more milk you choose to use, the fewer greens should be in the pile, to balance the mixture.

2. Water the Pile With Milk

Water your compost pile every day or as often as you can, but if you do not have enough milk to water the pile often, use more greens in the pile so that there can be enough nitrogen for your plants when the compost is ready. Continue watering the pile, especially with milk until you see that the process of decomposition has started. Remember to mix and turn the milk into the pile regularly.Watering Pile With Milk

3. Stop Using Milk After Two Months

Watering your compost pile with milk is good, but remember that milk needs time to decompose, just like other organic materials. If you continue watering the compost pile with milk even when it is almost ready, it will not fully decompose because of the amount of fresh milk. At least one month before your compost pile is ready, stop watering it with milk.

Start watering the plants because milk can attract pests to your plants. Insects such as ants and cockroaches and microbes such as fungi and bacteria can attack plants with too much milk on their leaves. These microbes can leave brown or black spots on the leaves, while the insects can damage the leaves.

To prevent pests from attacking plants in your garden, consider a ‘watering plants with milk experiment’ so that you may test just a few plants before using the milk for every plant in your garden.


Milk fertilizer is truly an awesome product for your plants, and here are some reminders from this article:

  • Pour milk, diluted, on the leaves of your plants as foliar fertilizer. It quickly corrects nutrient deficiencies.
  • When you see excess milk on your plant leaves after a while, wipe the leaves dry.
  • If you are using milk for composting, stop at least a month before you harvest the compost pile.
  • You can use spoiled milk for your plants. However, use it as a regular liquid fertilizer and not directly on the leaves of your plants.
  • While milk can help prevent some fungal diseases and other problems in plants, get other, or better products to fix your specific plant issues.

It’s time to feed your plants, and when spraying milk on plants, remember to remove the excess droplets by wiping the leaves some minutes later.
