Before you toss another tea bag, must check out this post! Tea bags are not just for brewing tea, there are so many TEA BAG USES in the garden that can be useful.


  1. Do tea bags bring in any animals? I want to try it but I live pretty close to the woods and don’t want critters on my porch.

    • I doubt it as they strictly provide nitrogen to the soil. They may even encourage the growth of fungi. Unless you have a massive mushroom problem I wouldn’t worry as there is a healthy balance of fungi. They also encourage nitrogen into the roots of plants at the molecular level.

    • I never use tea bags made from plastic, as we ingest that stuff!! Use only paper tea bags, then you don’t have to worry about plastic bags. If you are concerned about pesticides, use organic tea. Also, I brew loose tea, much better tasting, some Brits won’t use any thing else. :-)

  2. The only problem with a lot of teabags is that they are made from plastic or partial plastic that does not compost. Above is a picture of a box of Lipton tea. The bags are triangle shape. These are some kind of plastic. Not good for the soil.

  3. Thanks for sharing this, I have always used coffee ground and tea leaves in bags or fresh. They have always worked wonderfully with my herbs. I have repotted my herb seedlings today and watered with freshly made tea in my watering my newly potted herb seedlings. Squeezed out both tea bags and broken both tea bags and shared the the spent tea leaves around each potted herbs. Gaurenteed they will be very healthy happy plants. Tea Leaves as well as Comfrey Leaves are perfect widely used Organic Natural Fertilizers over my last 10 – 12 years growing my own vegetables and herbs xxx

  4. I take people’s plants out of their garbage cans and feed them tea, prune them and just wait.
    My friends will say, “Wow! What a great plant!” AND I say, “That’s the one I took out of your garbage!” Fun!

  5. The tea that is spoken about is black tea. Different from herb teas, but they are great as compost as well. I don’t know if the herb teas are acidic, don’t think all are, you can always check them out for their properties.
