My irises haven't bloomed the last three years on the side of my house in four years out in my yard and I'm not real sure what to do

If they haven't been thinned out in a while they could be over crowded, that will keep them from blooming. You may want to thin them or dig them all up and replant the best rhizomes spaced about 18 inches apart, and see if that works. If they don't get enough sun that can also affect their bloom.

May I ask what type of irises they are - bearded, siberian, reticulata, dutch etc? Do you have any photos?

welcome graybaby. that was concise advice 👍🏻in a nutshell. those are the two most common things that affect bearded iris bloom. also, don't bury the rhizomes too deeply. there are lots of online videos to help guide you through the planting.

Planting depth can be a real problem. Many people think 'bulbs' & bury them. In must cases the top of the rhizomes should be showing. Most plants should have at least a half day of sun.

How much sun do they get?

They are bearded irises. Also, i read I'm supposed to wait til July or September to thin them or can i do that now?

If they are really thick and most likely won't bloom, you could thin out some now and maybe add a bit of a balanced fertilizer, like a 10-10-10. Just a bit, don't over do it. Normally we do the thinning after bloom, and replant after the clumps get too large, but it's early enough you might still get some bloom from the rhizomes you leave alone. I'm not sure how far they have progressed in your area.

Thanks ya'll. Im gonna thin them now. Transplant some to a new area. I will keep ya updated. 🙏🌸✌️
