Did you know that used tea leaves are good fertilizers? Just mix the used tea leaves into your potted plants. That's not all: used tea leaves retain moisture, even after they are boiled, strained and cooled. Which is why they are of great help when you want to gift small saplings (cactii and other small plants) that grow in the pot to a friend. After carefully removing the sapling with the roots, pack the roots with tea leaves and wrap with aluminium foil. The plant will stay fresh for several days, which enables you to safely transport it even over a long distance.
