June, what type fertilizer did you use?

One of my neighbors has a lot of the tall purple bearded iris. They bloom good every year and she never does anything to them.

I used Espoma Rose. It said for any plant that you want good flowering. I’ll let you know if it works. I only use organic fertilizers.

I got this from Schreiner's website.

"When Tulips bloom in your area, it is time to fertilize your Tall Bearded Iris. Bone meal, superphosphate, or a general fertilizer with a 6-10-10 balance are all effective. Be sure to read manufacturer's recommendations for your soil type. Avoid using any fertilizer high in nitrogen, such as fresh manure, because too much nitrogen encourages rapid foliage production instead of blooms, and can lead to rot. If fertilizers are applied, avoid placing them directly on the Iris rhizomes as this can burn and injure them. Apply as a top dressing around the plant and work into the soil. We recommend a fertilizer low in nitrogen, such as a 6-10-10 mix.

Beautiful Irises. Thanks for posting Ruth!

Thank you all for your comments.

Walking thru the yard yesterday I found a very small Iris Danford reticulata in a pot. I thought all of those had died. Another gifted one that has never bloomed for me. I'm going to move it to a bed to see if I can save it.
