Did your irises bloom for you this year?

A few weeks ago my leaves on my irises were lush and green, but not a bud was to be found. Then one little bloom made it's way up in a completely different place in my garden, so I was wondering why I didn't have any blooms on the others! In a panic (OK, I’m being overdramatic–I’ll say out of curiosity), I consulted Anne Marie, who gave me some very helpful advice. Then, lo and behold, a couple of rainstorms brought forth the giant purple buds on my beloved irises and they’ve been blooming ever since.

In any case, I thought I'd share Anne Marie's tips for any readers who were not lucky enough to have blooms this year.

These are probably a type of bearded Iris. They should bloom reliably for you each year unless…

  • They have been moved or were divided last year (they take about three years to get back to full bloom again).
  • They are now too shaded; they need at least six hours of full sun.
  • The soil is too rich or too lean; too much nitrogen fertilizer can cause them to have little or no bloom and lots of foliage.
  • They are planted too deep; the rhizome should be peeking through the surface of the soil.
  • They are overcrowded; this will cause fewer blooms.
  • They have been attacked by an iris borer–look for shriveled or sunken rhizomes where the iris borer has done its damage.
  • They are being grown in too soggy of a location; they prefer to be slightly dry.

I definitely need to thin mine this year and will be following the tips in this article to divide them.

The last of my tasks

The weather has just not cooperated this fall. Granted my schedule can be a bit hectic, so I can't just expect Mother Nature to conform to MY timetable, but seriously, does it have to rain every time I have a free moment? It poured this past weekend, so I didn't get the opportunity to do any raking, but I managed to sneak out today for an hour before work and get some of those leaves up in my backyard before the snow flies.

The one thing I've neglected to do is trim back some of the lily and iris foliage around my yard.

I asked Anne Marie if I can cut it back before winter and here is what she had to say:

  • If your iris and lily foliage is ready to be removed (i.e easily pulled out) go right ahead.
  • Lilies: After the foliage has naturally died down, remove all but 4 cm of the stem so you know where the plant is next spring.
  • Bearded iris: Do not mulch, cut foliage down to 15 cm.

And alas, as I'm about to post this, it's starting to snow.
