    One of theain reasons Iris's don't bloo but have beautiful leaves is because of too much nitrogen. Fertilizing lawns surrounding the Iris is sometimes the cause. Use an organic fertilizer, compost or just plain bonemeal to fertilizer them. I would just give them bonemeal this year and a lower nitrogen organic all-purpose thereafter. Another cause could be not enough sun- they love full sun, 6+ hours. Hope this helps.

    You could try dissolving one tablespoon of Epson Salt in a gallon of water. Pour it on the soil at the base of the plant. Then give them more water. The extra water will help the roots receive the E Salt that much quicker. This process puts enzymes into your soil and plants flourish with it. You can repeat every two weeks. Best of luck to you.

      Thank you so much. I will try the E salts. I had heard about it for vegetables but had not tried it for any other plants.

    Hopefully not only the roots are covered but the bulb itself should be too. You should just see the base of the leaves

    You have to leave the rhizome half uncovered...putting just enough of it in the ground to hold it in place. Put all the little roots at the back of the plant in the ground. I have always had to cut off the greenery to get them planted. For those I bought with blooms, I staked!
