We have four bushes located in the front of our house that are settled in what I believe are red lava rocks. We would like to go to some form of mulch, tree bark etc..to place around the bushes. Is the removal of all the rocks necessary for this to be accomplished? |
It isn't necessary to remove the rocks; you can just place new mulch over the top. But eventually the mulch will decompose and either raked up or covered over again with fresh mulch. If this isn't a concern for you, go ahead and place the mulch over the lava rocks. Try to avoid piling the mulch up against the main stems of the plants. If the mulch touches the woody stems of your plants it can hold too much moisture against them and cause the bark to rot. Good luck with your garden! |
