propogating purple oxalis bed..
Some of the oxalis tubers are near the surface in big clumps and others are still buried perhaps 2-4 inches below. Can I break up the large bundles I see near the surface (this will create more plants, right?) -- and would laying soil or mulch over the tubers already a few inches into the ground cause them to be buried too deeply or will they still push forth? The bed area is a bit messy with debris and really could use a new layer of soil
Thanks for any help! : )
