Will my Dutch Discovery Irises survive the winter if they are starting to come up now, November 29th?

Question

I live in Tennessee. We've been experiencing a week and a half of unseasonably warm weather. For instance, it's supposed to get up to 74 degrees F today, November 29th. I looked out at my garden and saw that the new Dutch Discovery Iris bulbs I put in late October are poking out!

Will they survive the winter? It is forecast to get down below freezing by Friday. Can I please have some advice to keep them from dying through the freeze because they have already started to sprout?

Answer 1

Don't put mulch on them--that will insulate them from the cold and encourage them to grow more. Leave them uncovered and don't cut the leaves--they will photosynthesize and replenish the rhizomes as long as they are green. So if you don't do what the first two answers are telling you, they should be OK in the spring. Plants are used to Mother Nature playing jokes now and then.

Answer 2

The Iris should survive. Put some mulch on them and take it off in the spring. The weather has been strange this year. I still have some flowers blooming which is very unusual where I live. Don't worry about them poking out they will stop once it's gets cold.

Answer 3

I examine in a soaps magazine that Sharon and Jack will do a narrative with regard to the mustache and then Phyllis and Nick will do an exhibit on "the actual Jack Abbott" as payback...then Jack will do an editorial, asserting, confident..that's actual that he needs administration of under pressure type magazine (interior the magazine)...and that's while Sharon will area with Nick that Jack has long previous too far. The magazine is meant to be approximately trend, no longer tit for tat returned biting among the editors.

Answer 4

Trying topping them up with a deep layer of mulch and/or put clay flowerpots over them upside down. That might do the trick! Good luck.

Answer 5

Forget them, they will look after themselves, they do not need pampering
