Hi I'm new to the forum. A bit of background then come the questions.
I have had iris for years, only a few old varieties that I've paid little attention to and have thrived. So, I decide since they're such no brainers I'd put in a new bed just for some of the wonderful and varied hybrids you can buy on line. Last fall I planted about 20 and most of them bloomed this spring non lost to pests or disease. I'm encouraged so I order A LOT more. The first batch I planted in early July right before the monsoons started, I live in W. Pa. I ordered form 4 different nationally recognized growers, all planted within 2 weeks of each other. So far I've lost 20 new iris to bacterial rot all from one grower! My first question is, are some iris more susceptible to rot because of, region they came from, fertilizer used, etc. or is this just a coincidence? Second question, can I treat the soil with sulfur or copper or anything else to make sure there's no bacteria left in it?
Ps, I've never been on a forum before so let me know the correct etiquette. Thanks
