Crushed fruit tree spikes
Hello. When I first started growing I bought a bunch of tree spike fertilizer. Well I still have them and they are great for nutrients and micro nutrients. My question is, could I crush them real fine and use them in the topsoil with my mulch under my pine chips? I assume they would still be slow release? I could even crush them up a little course as to let them slow release the nutrients into the soil? Would this be OK?
