Keep chopped banana skins your refrigerator or freezer until there is enough to fill a blender 2/3 of the way. Add a cup of water and blend to a slurry. Place slurry into a normal sized bucket (9 litre) and fill half-way with water. Mix well and apply a cup fortnightly (every 2 weeks) to tomato seedlings and the base of growing tomato plants. The liquid contains magnesium, phosphates, calcium and other minerals. Because of it's sulphur content, it is also suitable for all brassicas (Cabbage, Cauliflowers, Broccoli etc)

You can also use whole over ripe bananas and tuck them into your staghorn ferns. They love 'em!
