Sorry if I'm asking something I "should" know, but all these many years of gardening, I've never understood whether it's OK to cut part-way off leaves that are dried and ugly from the tips half-way down.

Does it upset the plant (Clivia is what I'm on about at the moment) if I "clean up" the look of the flower bed? Will the remaining part of the leaf continue to feed the plant?

Or does cutting off part of a leaf degrade its function?

TIA
