2. Bury Some Treasure
There are many natural materials that can provide long lasting fertilization to your fruit trees – all you have to do is bury them when planting the tree. Hair, fur, and feathers are all great sources of phosphorus, a key nutrient for flower, nut, and fruit development. These are slow to decay, and provide years of nourishment. My favorite is crushed oyster shells. These nautical nuggets provide calcium and other minerals that can sweeten the taste of your fruit and improve the health of trees.
