An Article About Is Tea Good for Plants and Why Plants Love It So Much Plant America

In this article, we have discussed many reasons why people need to water plants with used tea. In this guide, you also learn what kinds of teas can be used for plants and how to make them at home.

Is Tea Actually Good for Plants?

🔥 Quick Answer

Yes, tea is actually good for plants because it is enriched with nutrients, vitamins, and antioxidants. Tea makes a fantastic fertilizer that helps plants grow better, resist infections, and become healthier. Plants that grow well in acidic soil respond the best when given tea as a feed.

– Nutrients in Tea That Are Good for Plants

Tea of any kind is made up of a ton of chemicals and substances that help plants grow well. Research has shown that most tea leaves comprise 0.25 percent potassium, 0.24 percent phosphorus, and 4.4 percent nitrogen. This makes them almost as effective as any good synthetic fertilizer but much safer.

Tea also contains polyphenols, the most significant of which is tannic acid. Tannic acid strengthens the plant’s natural defenses and helps them fight infections.

Antioxidants present in teas, like flavonoids and phenols, protect the cells of the plants from cellular damage. Green and black teas are high in valuable vitamins like vitamins C, D, and K that help plants grow better.

– Plants That Like Tea

Doubtless, tea contains nutrients that benefit almost all plants and vegetables. Some homegrown plants respond better than others when it comes to fertilization with tea. These plants like to grow in soil with a slightly acidic pH level. This is because all teas are somewhat acidic and alter the soil’s pH with consistent application.

Most varieties of fern respond really well to a tea feed. Hydrangeas, tomatoes, spider plants, and philodendrons love being watered with tea regularly. Plants that thrive on alkaline soil, like lavender, cauliflower, and asparagus, should be fertilized with a natural fertilizer other than tea.

Why Is Tea Good for Plants at Home?

🔥 Quick Answer

Tea is good for home plants because it helps eliminate houseplant pests and invasive weeds. Tea affects plant growth by adding nutrients to the soil and strengthening the plants. It has antifungal properties and helps prevent and treat fungal infections of plants.

– It Repels Pests

Why go for synthetic fertilizers when you can use tea bags from your kitchen pantry? There is no need to use fresh ones either. After making tea for yourself, place them on the soil near the plants. They will prevent all types of pests like mealybugs, spider mites, and slugs.

If pests have infested a plant, then using a spray made of tea is suitable for it. Take a spray bottle and fill it with weakly brewed tea. Spray on the plant under attack every week, especially under the leaves, until the whole pest population dies.

– It is a Natural Fertilizer

Watering plants using tea makes an effective natural fertilizer. It can be applied on most acidity-loving plants safely two to four times a month. The three most valuable nutrients needed by plants and vegetables are present in ample quantities in all kinds of tea.

Dry Leaves can also be used if you don’t use liquid tea that has been brewed. Even leaves that have been brewed to make tea make effective fertilizers. Place tea leaves or tea bags over the garden soil and mix these leaves using a rake.

– Tea Suppresses Weeds

Tea grounds have excellent weed-repellant properties and are effective against almost all common weeds in the US. This fascinating tea ability encourages most plants’ growth while suppressing invasive species’ growth. You cannot expect the tea to eradicate all the weeds invading your lawn in one go.

Use tea leaves to brew a weak to moderately strong solution and spray it over the weeds. It would help to cover the weeds using rubber mulch or a rubber cloth afterward. Multiple applications of this tea will be needed to burn the weeds.

After they die, they will have to be dug out using hands or instruments for 100 percent eradication.

– Tea Has Antifungal Properties

Fungal infections are the most common plant diseases and a home gardener’s worst nightmare. Some fungal diseases like powdery mildew do not kill plants but lead to growth retardation.

They also make the plant look weak and ugly. Other infections like root rot are downright fatal and will kill a fully grown plant within weeks.

Tea helps plants become strong and resist these infections due to their high antioxidant levels. You can also make foliar sprays made of tea to treat a plant infected with a fungal disease.

Like most natural substances, consistent application for several weeks is needed before the plant becomes 100 percent healthy.

– Helps Compost to Decompose Faster

Tea is good for plants because it enriches your homemade compost pile and helps it decompose faster. For once, it is acidic in nature and will also increase the acidity of the compost bin. Adding any tea, whether it is black or green, will instantly increase the temperature within the compost bin.

This has been found to speed up the composting process and release nutrients faster. The result is that not only can you compost leftover food more quickly, but it also provides more nutrients to the plants. You also get to recycle food and tea waste, making this a very eco-friendly endeavor.

– Tea Is Food for Earthworms

As a fertilizer, tea is a rich food source for the earthworms living in the soil. Earthworms thrive on the nutrients that are added to the soil after a tea feed. Multiple research has shown a spike in the earthworm population after just three to four tea waterings. You might be wondering whether that is a good or bad thing to happen.

Earthworms are what we call beneficial insects in the plant world. They help plant roots grow better by burrowing pathways in the soil. These pathways allow water and air to reach the roots and keep them hydrated.

They also break down the organic content of the soil so that the roots can retain the micronutrients better.

– Keeps Cat Away From Plant

Cats are not the best pets to have to roam around your backyard. They like to dig around the plants and in the soil as a hobby. If a cat is particularly nosy and nothing else will keep it away from destroying the plants, using tea will most definitely help.

The reason tea is so successful at keeping cats away is surprisingly simple: they hate the smell of tea. You do not even need to go out of your way to buy a special tea or make a complicated concoction. Just pour leftover tea on the soil around the plants where the cat loves to dig. You will notice that the cat will start staying indoors after the tea application.

What Type of Tea Is Good for Plants?

Almost all types of teas are suitable for plants when given once or twice a month. You can use black, herbal, or green teas as plant fertilizer, insect repellents, and antifungal agents. After brewing, liquid tea should be diluted, or a used tea bag should be used instead.

– Herbal Tea

These teas are no less than green and black when watering plants with a rich fertilizer. Chamomile, willow, and comfrey are all trees derived from herbs that serve as instant fertilizers for most plant soils. However, not all plant types respond best when given these teas; some might even exhibit leaf wilting.

– Green Tea

Green tea leaves are readily available everywhere at very economical rates. They can be used in gardening as an additive to the compost bin, mulch, and soil amendment.

Ornamental bush plants like roses, blueberries, and hydrangeas love being watered with this tea. In a vegetable garden, the tomato yield has been shown to exhibit a significant improvement after regular green tea watering.

– Black Tea

This tea contains vibrant tannin levels that help protect almost all types of plants against various problems. When absorbed as a nutrient by young plants, Tannin becomes stored in their stems and bark.

It then provides a lifelong resistance against bacteria, fungi, and pests to the plants—tropical indoor plants and a lot of vegetables like this tea as regular plant food.

How Can You Use Tea Leaves for Plants?

You can use tea leaves for plants in three different ways depending on the plant’s needs. Tea makes a functional green component of any pile of compost. Its leaves, both fresh and used, can be used as a layer of mulch or made into liquid fertilizer.

– Add Tea Leaves to the Compost Bin

Just add a tea of your choice to the pile of compost churning in your backyard. Tea leftover after breakfast is a rich addition of organic greens to the compost. It not only adds a ton of nutrients to the pile but also speeds up the composting process of the rest of the materials.

Take care not to add too much tea to the pile because it is acidic in nature and might disturb the green and brown balance of the bin.

– Add Tea as Mulch

The easiest way to incorporate any tea leaves is by using them as mulch. Collect enough leaves to be spread over the required soil area in a uniform layer. As the standard practice, the tea mulch layer should be at least two inches.

These leaves can also be added to other mulch items like grass clippings, newspaper pieces, or wood bark. As mulch, these leaves help retain moisture in the soil and keep it from drying out in the summer.

– Use Tea in Liquid Brewed Form

Before using it on the lawn, you need to know what plants like tea water. Take the leaves of any tea and brew a weak mixture. A more potent combination is not recommended because it has been observed to cause chemical burns to the roots and shoots of plants.

Another prevalent type of tea used in plant care is compost tea. This is when a small amount of compost is added to a jar of water and left undisturbed for 24 hours. Afterward, the water it is strained out and used as a liquid fertilizer.


In this article, you got the answer to the question, “Is tea water good for plants?”. Let us recap the answer here:

  • Tea of any kind is rich in nutrients, antioxidants, and other valuable substances that help plants grow better.
  • Tea can be added to homemade compost, mulch, or made into a liquid plant feed.
  • Tea helps house plants fight infections, infestations, and invasive species like weeds.

Now that you know how helpful tea is in gardening, you will never let used tea go to waste again.
