Gardening newbie and just planted my first Rhododendrons. I was wondering about mulch. Currently I've been using compost as mulch (whatever I can find, but around here it's mostly decomposed sheep or cow manure) for all my plants, but since Rhodos like more acidic soil I've been reading suggestions to use conifer needles or bark.
Well, that is not always easy to find. Plus I like the uniform look of my garden beds with the nice black compost on top. So is it ok to keep using compost as my mulch? Or should I really be switching to a more acidic mulch?
