Should irises be mulched?
An employee mulched our flower beds with some lovely compost, but he also completely covered-up the iris roots. Is this a bad thing? The irises are blooming well now, but they already had their blooms set when he mulched. I have heard that iris roots need to be exposed to sun to bloom well, so I'm worried that my reblooming irises won't put out a second batch of blooms if I don't go out there and (laboriously, at 6 months pregnant :-) uncover all the roots. He must've thrown shovel-fulls of compost over the irises because the are well covered, even in the middle of the patches.
