Using tea leaves to enhance plant growth
The hypothesis that rose plants planted in soil mixed with tea leaves will grow more quickly, is proven to be true.
Compost soil is known to be very good for plants but using compost made from tea leaves has been found to be even better for enhancing plant growth. The tea compost is known to provide many benefits to plants, especially rose plants. The used tea leaves are also a rich source of antioxidants for the plants.
Try to repeat the science fair project using different types of plants.
The science project experiment can be repeated using grounded coffee instead of tea leaves.
