I cover everything with lots of leaves. I have 5 Crepe Myrtles that I build a cage around and fill with leaves. They are only hardy to Zone 6 at best.
I will be piling up about 4 - 5 feet of leaves and straw on my Hardy banana.
My Muskogee got > 15 ' tall, but did not bloom
4 of the 5 bloomed - 3 Pink Velour and one Dynamite. Next year I should also have a blooming Sioux which I grew from seed last year. I have 2 more NOIDs that might bloom next year.
Yeah - the Earl May shrubs were covered with 3 feet of leaves after I sank the pots. Everything came thru fine.
Did I mention I will be going to Earl May tomorrow?
Back on topic - It bit me again today somehow. I was no closer than a foot!
BTW - My PP is NOID. How many different types do you have now?
