The answer to that question:
Can I mulch my iris plants?
only when you are bedding them down for the winter. During the growing season, they prefer to dry between waterings. Iris and daylilies remind me of one another, and are cared for in almost the same way. Iris need to be separated about every three or four years. The rhizomes (fleshy root) can be dug up and separated. This is healthy for your iris bed, and you can spread your irises to another location in your yard. They can almost be forgotten, except for occasional waterings, and then they burst forth again in the Spring with jubilant blooms. I bought three that bloom more than one time a year. Mine seem to prefer the cooler weather, and almost shut down during the heat. Early Fall they will begin to bloom and the purple one will bloom all the way through Winter into Spring. Two of mine did bloom through the winter last year, but we had very little cold.
Recently, I wrote an article pertaiing to leaf streak in daylilies. This is a fungus caused by too much moisture. The daylily prefers to also become dry between waterings. It is best to groom your plants often, while the leaves are dry, and also separate plants when the large ones start reproducing. So, for the daylily, do not mulch during the bloom season, only to winter in when the weather turns cold. At that point in time, I mulch with pine straw and bark mulch, as though I’m putting a blanket over them.
Like the iris, they are sensitive to moist feet. I have already begun featuring another bed full of daylilies. They are so spectacular in color, even when it continues to be hot and dry. I will shop for the cultivar that is resilient to leaf streak, and like the iris, daylilies come in colors you can mix and match to coordinate a specific feeling for that certain part of your yard! Best of all – I love perennials. Once you get them established, they return year after year. The daffodil is another one of my favorites that you forget about until it brightens your yard over night in the early Spring. Once I see the daffodils blooming, I know our winter is almost over.
