! Peat moss....comes in a 'bale", like straw, or hay, and , when it's shredded, is used in a lot of 'soilless ' potting mixes. "Peat", on the other hand....is what the "peat moss", and other "swamp" plants turn into after a few thousand years of aging.....it is actually "soil". Just wanted to throw that out there, because if you buy a bag of 'peat".....that's probably NOT what Schreiner's uses!
Sphagnum Moss is the 'right" name for "peat moss", and you should be able to find it, either shredded, or baled, at a good garden store.
Yes very good to point out. I was just trying to shorten peat moss to peat because I had already written it.
However I always thought of Sphagnum Moss as totally different than what is used in plant mix. I thought that was like what a lot of orchids come potted in and also used for terrariums. I have a bag here of it and it is tan and almost stringy, while the bales of peat moss I buy are more similar to something between soil and broken down bark mulch. Not sure if I was thinking on using the correct stuff.
I copied what Shreiner's has on their site. I was off on the percentages.
Quote "Iris can be successfully grown in containers. A 6" to 8" pot will work for Dwarf Iris; a 12" pot will work for Tall Bearded Iris. Make sure your pot has good drainage. For soil, we recommend 45% fir bark, 20% pumice, and 35% peat moss. Leave at least one inch below the pot's rim, and leave the top of the rhizome exposed. Water only when the top two inches of soil are dry. Overwatering will cause rot. Keep the pot outdoors during the winter. When bloom buds begin to appear in the fans, bring the pot inside and place in a bright sunny window. After bloom, be sure to divide your Iris and replant outside or into more pots."
