bearded iris

Asked on 5 May, 2008

My bearded iris did not bloom this year (10% did) All get at least 6 hours of sun a day, some full sun. They are not overcrowded, but do have a light layer of mulch over them. Any suggestions would be appreciated.

My experience is that they hate having the corm covered. Best left exposed to bake in the sun.

If they get too clumpy they stop flowering. When you divide them up they take several years to restart flowering. My mother used to nip bits off each year to ensure flowers. This is easy in light soils and damn nigh impossible in clay!

Good luck

I expect it's the mulch that's the problem - as Ann said, they like to be exposed to the sun. I planted a load of irises 2 years ago and they are only this week coming into bud for the first time! Can't wait!!
