How best to use compost on fruit trees
I am currently not using any chemical fertilizer on my trees.
Right now I rake back the mulch once a year and put down a layer of compost, then rake the mulch back over it.
From time to time I also pour some liquid Aggrand organic fertilizer on the soil.
Is this enough to nourish the trees as they get bigger? Or do I need to be putting anything down further into the soil?
