I love the iris family of flowers! And right now is the ideal time to plant this hardy, beautiful gift from Mother Nature.
Let’s learn some interesting facts about irises, and talk about how you can plant them in your garden to create an amazing rainbow of colors in the spring.
Bearded irises are sturdy easy-to-grow plants needing only a sunny spot and well-drained soil. The rhizomes are available in late summer/early fall. Bearded irises have bigger showier flowers than other varieties. Depending on the variety, they bloom anytime from mid-May to mid-late June and some varieties, called remontants, will bloom again at summer’s end.
To plant bearded irises, choose a sunny spot with well-drained soil. The rhizomes come with roots and a fan of leaves at the top. Plant the stem with the root side down, but the top of the stem is exposed to light and air. Top-dress lightly with Bulb-tone. Feed again in the spring when they start to come up.
Always plant bearded iris at least 12” apart as the rhizomes make new plants every year. If they’re too close together, they will not bloom as well.
Regular irises don’t need much attention after they bloom except for water in periods of extreme drought. Keep their beds weeded and if you mulch, DO NOT mulch over the top of the rhizomes. Be sure to keep dead leaves or debris out of the iris bed as they can encourage rot. Irises do not like in-ground sprinklers.
There are bearded irises that bloom in the spring and again at summer’s end. If you have re-blooming varieties, then feed them after they bloom the first time and keep them watered over the summer—remembering to let them dry out partly.
Dutch irises are smaller than bearded irises so take up less space and are good for adding color where space is more limited. They are about 24” tall and usually bloom in May.
Miniature iris bulbs are also available in the fall. They bloom about the same time crocus do and are daintier—about six to eight inches tall. Both Dutch and miniature irises come in around the first week of September and can be planted in mid-October. Like bearded irises, they prefer full sun and well-draining soil. Plant the bulbs about 4 inches deep.
Irises are tough, durable, and perennial bloomers, and they are not generally bothered by pests—very important here in “Deer Country.”
