I learned the hard way that all I needed to add to my sand (called soil) is mushroom compose. No more black cow, sphagnum moss, etc. All plants, potted or in-ground get 2/3 sand 1/3 mushroom compose. Mush. Comp. added couple times during the season too. That's what they'll have when transplanted into the ground.
So my question is can you start Irises off in pots and transplant later? What is later? Before a cold snap or before spring? While I'm on a roll, do irises require a dormant period?
Do irises require any of the "special" fertilizers? One was 5-50-10 which just blew me away. I ASSUME a force bloomer ????
Having my Irises thrive in Florida is my main concern.
One more thing. Sun. When everyone else says sun for at least six hours, my hardiest plants are wilting. Where I intend to put my Irises will have sun from rise till 4-5 p.m. If it didn't rain that day, I have to water. By day two, plants are in rough shape, and day three their dead.
