Using 'grass clippings tea' as fertilizer is already an old method by farmers in introducing a natural and organic form of fertilizer into their plants. This is rich in nitrogen which promotes lush growth and greener leaves. This tea fertilizer is best for leafy vegetables such as pechay ( Chinese white cabbage ), lettuce, kale and other leafy veggies.
