well it warms up too early and the iris makes buds and then it comes a freeze and kills them. Then they don't bloom.
I try now to buy later blooming iris. The early blooming ones-a good chance every 2 or 3 years they get frozen off.
Same here for our fruit trees, the peaches especially, they bloom too early and then get frozen.
This was for Lebanon mo, zone 5b. I never plant my tomatoes out before the weekend of mother's day, sometimes a week later to be safe depending on the weather. Last year it was JULY before we started having warm nights. Really cool nights/mornings and lots of rain.
Paul, I will look into that, thanks for a suggestion!
