I live in Southwest Washington (Clark County) and have been pruning my crocasmia back every year. This year I discovered that if I pull the leaf a little they pop off at the cap of the plant. Is this damaging the plant or is it OK to do so? I will be putting bark dust on them in a few weeks before the cold sets in. Please advise.

Thank you for your question. Is the plant in question the bulb described here? https://hgic.clemson.edu/factsheet/growing-perennials/
Are you pulling a leaf off of the bulb? Once the leaf's nutrients have been created through photosynthesis, both creating food for flower production and replenishing the bulb, leaves can be removed safely. However, you will reduce the potential of disease by pruning them, rather than pulling them off. By now, though, they will be losing their leaves naturally. I hope this is helpful. Good luck!
