FERTILISER BASKETS - Used to enclose solid fertiliser in order to prevent disturbance by birds. Each time the tree is watered a portion of the fertliser is washed through the soil.

There are a number of designs: some (as illustrated) are placed over the top of the solid fertilizer and some have lids on top and spikes on the bottom so that the fertilizer is self-contained while the spike keeps the basket firmly positioned in the soil.c
