Coffee grounds give your tomato plants a boost when added to compost and used in the garden as organic fertilizer. Asides from giving the tomato plants a boost, it also attracts earthworms and also deters insect pests and slugs present in the garden.
To add coffee grounds to your tomato plants, you can add the grounds to the compost bin but do not overdo it. Keep the coffee grounds to nothing more than 20% of the material added to your compost.
Just like fresh grass clippings and kitchen waste, coffee grounds are also considered to be green materials and thus, must be balanced with brown materials including dried leaves so as to have proper composting.
1) To add the grounds to the tomato plants, spread a one-half-inch layer of used coffee grounds around the base of your tomato plants and then proceed to top it with 2 – 3 inches of organic mulch. Studies reveal that coffee grounds compact easily and prevent good air circulation when applied in thicker layers but a thin layer gives the tomatoes nitrogen boost.
2) You can also get a cup of used coffee grounds and have it sprinkled around the base of your tomato plant while also working it into the top 2 – 3 inches of soil with a claw or perhaps, a trowel. This causes a decomposition of the coffee grounds and thus, preventing issues with soil compaction.
3) When transplanting tomato seedlings, add well-composted coffee grounds to the planting hole. This will help to improve soil composition and also provide a source of nutrients to the tomato plants.
4) You can mulch around tomatoes with coffee grounds throughout the summer. Doing this will help in conserving the moisture while also preventing weeds and adding nutrients to the soil.
