|Don’t throw out your used coffee grounds just yet. Your plants are craving something they have left.|
That clump of used ground coffee you have left in the filter is high in nitrogen, making it a good mulch for fast-growing vegetables such as tomato plants for both the nitrogen boost and for coffee’s ability to help control late blight. Used coffee grounds repel snails and slugs as well as adding nutrients to the soil. Coffee grounds are also cherished by worms so simply toss them onto the garden and the worms will find them.
Just collect your used coffee grounds each day and spread them out on a pan to dry until damp but no longer soaking wet. Spread your fresh grounds/Fertilizer around the base of the needy plant and it will release the nitrogen as the grounds break down and water passes through them.
