Coffee medium or dark!
Coffee
Acid loving plants such as azaleas, roses, heathers and evergreens love to have your coffee grouts once you’ve finished with them! Coffee contains potash, nitrogen, phosphoric acid among other minerals and vitamins. Just apply your grouts as you would mulch, around the base of the plant
Egg Shells
Egg shells are 93% calcium carbonate and 1% nitrogen so they are the perfect fertiliser for all types of plants. Calcium is an essential plant nutrient, important for cell function and growth. Collect your egg shells, place on a piece of kitchen towel and leave them to dry out either in an airing cupboard or on a warm sunny windowsill. Crush them, then blend them into a fine powder with a hand blender, then apply around the base of the plant
