I Have A Garden Of Irises With Garden Spiders, They’ve laid Their Eggs On The Leaves

Question

Should I not weed and cut the this fall

Answer 1

Weeding is fine, but I would not prune unless they are diseased, anyway. Spiders are beneficial, but weeds will be counterproductive.

As long as you leave what is on the Irises, physically, then removing the rest shouldn't cause too much of an issue.
