I have an iris that is planted under shrubs. Nothing blocks it's growth, soil wasn't the best so I had fertilized it and added organic soil around it. I've kept it watered well so it's not dry but not soaked. The green leaves grew to about a foot and stopped growing. I see the tuber sticking out above ground so I know nothing is stopping it from growing taller. Is there anything that will fix this?

Iris do best if planted in full sun. If it's under some shrubs it probably isn't getting enough sun. I'd move it out into the open and see what happens. Good luck!

Keith!! with Tom!

I concur with the above two suggestions. Iris have to have a certain amount of sun in order to produce a bloom. Some will bloom sporadically in dappled shade but most require at least six to eight hours of sun a day to meet their full potential. Full sun during the growing season is best.

Irises also don't like competing with the roots of woody plants. I've found irises will do pretty well in the vicinity of tap-rooted trees, such as many oaks, so long as they get a decent amount of light. But, shallow rooted trees and shrubs are a completely different story.

At least a half day sun. Shrubs probably also steal the nutrients in the soil.

I dug it up, there was two on top of eachother. Only two inches of soil below, the rest were roots and rocks. I removed all the roots and rocks, dug a 3 foot hole, added new organic soil, and moved the plant out more where it will get more light. Hopefully I fixed the problem!

It may even bloom for you next spring, Keith. Sometimes after moving them it takes a year for a bloom but since you got it right back into the soil it may perform well. When it does bloom take a photo and post it here.

Keith!

Good job, Keith!!
