I just received 1 dozen Irisises in a shipment. Do I plant them now or in Fall?

I just got a shipment of Iris roots. About half a dozen. I am not sure where to put it in my garden yet? I need to make another raised flower bed. Iris do they grow better in full sun or partial shade? Should I wait until fall ? It's still getting hot and dry here in Northern Utah? Help! I also have about 100 Tulip plants that needs planting? Now or late fall? Which way is better?

Please Goggle Schreiner's Irises for the help you need. This next info came from their web site and they have all the answers you will need. Good luck. They also have some fabulous Irises too.

Planting Iris



The best planting time for Iris is in July, August, and September. If you're in an area with hot summers and mild winters, September or October planting may be better. Pick a site for your Iris where the plants will get at least a half day of full sun. Iris need good drainage; the rhizomes will rot if the soil stays too wet.

Prepare a raised bed or mound with loose soil. If your soil is heavy clay, add sand or organic matter to loosen the soil. Iris prefer a soil that's slightly acidic (pH 6.8). Plant the Iris so that the top part of the rhizome is above the soil line. Press the soil around the rhizome firmly and water in. Once your Iris plants are established, they'll only need to be watered in very dry conditions.
Reply:EITHER IN THE FALL OR EVEN BETTER IN THE SPRING AFTER THE LAST FREEZE/FROST
Reply:I would advise waiting until fall....



You don't want the iris rhizomes to be too deep just enough to be covered with dirt. If too deep they will not bloom. The foliage will come up they just won't bloom.
Reply:You can plant em now. Irises do better in full sun. Have a bunch that have multiplied like crazy!

You can plant the tulips whenever too, they all just need a hard freeze for dormancy to be ready to bloom in the spring - have fun :)
Reply:In Utah I'd do it in Feb, after the last freeze...
Reply:It is best to plant Iris in late Spring but I have managed at the end of Autumn or Fall too, but our weather is cool temperate. When planting make a small hill in the earth and place the corm on the top and comb the roots on either side of the hillock.



Tulip bulbs should be kept in the fridge [not freezer] until late Summer
Reply:Mid August is about as hot and dry as it gets here in the Dakotas but now is the time to divide or plant irises and tulips too. On tulips, some say to wait until the soil temp goes below 70, I never bother to even check, just plant'm when I get'm. RScott
