Q.Wood Chips Decompose
I cut down a large maple tree in my yard that was dying. I planted a flower garden where the tree had been this spring. There was a lot of wood chips in the soil. I removed a lot of them, but there was still a lot of wood chips remaining in the soil. I later read when the wood decomposes it will use the nitrogen and I will need to correct this problem for my plants to live. I used a slow release fertilizer and worm castings when I planted, but feel I will be needing to add extra nitrogen to the soil. What should I use and how often will I need to do this? My plants are already a little yellow on the bottom leaves. How long will it take before the wood chips decompose? I planted blanket flowers, carnations, aster, and queen salvia. Any advice will be helpful.
