problem when rooting cuttings
I have been trying to root some cuttings for about 4 weeks now. They look healthy above ground. they are even starting to sprout new growth. I decided to sacrifice one of them to see how they were doing. underneath it was rotting. I checked a second and it too was the same way. The bottom half inch was rotten. This seems odd to me. The above ground portion still looks nice and healthy.
The question is what I should do now. I'm thinking the other cuttings are probably the same way. Since the upper part still looks healthy could I just cut the rotten part off and start over?
