Elephant ears and Spider plants

Question

How to thin them out without hurting other plants and soil?

Answer 1

It will not hurt them to remove some of the bulbs, or plants. Both can be thinned out, but I would wait until they are not actively growing. If they do not have a rest period where you are, then it can be ok to do this at any time. Just dig the plants, and bulbs out as you would normally.
