I am growing my irises on raised beds, with sloping sides that I try to keep free of weeds. The areas between beds are what I am thinking of using some kind of mulch on so I can work easier than in mud or dirt. Would this hurt the irises? Do slugs avoid evergreen mulch?
Evergreen clippings for between Iris beds?
I don't know if slugs don't care for evergreen mulch. Maybe use the evergreen mulch but first sprinkle with a good layer of builders sand (lowe's or home depot w/ the concrete mixes).
This is good info too--no pesticides just basic stuff:
pine needles are great around the iris, just not over the rhizomes
I would be careful not to get too much acid in the soil. Iris lick neutral Ph.
True - but this is just something to walk on. My compost additions come with lime in it from the cowyard, so I am not too worried about acid soil!
