I live in Zone 3A and have a mixed rose border with lots of bulbs in it. I applied a heavy mulch of leaves over my bulbs a good while after freeze-up.
This is the third year I do this mulching.
Mulching is always good, especially in Zone 3 a..........(where on earth do you garden, Joe??....brrrrrrrr)
Now I looked under and lots of Muscari are poking up. Oh dear. There must have been more heat still trapped in there than I thought.
Not a problem. Muscari send up their grassy foliage first, and THEN the little conical "helmets" of flowers..........
What's odd is I thought this growth could not happen without a good hard cold dormancy period. My tulips, narcissi and everything else are not coming up.
Those bulbs are way smarter than the muscari. And the muscari are tough, they'll be fine. The others will wait until true springtime to show their noses....
I certainly can't save the muscari from the rest of winter. So I just put the leaves back.
You did fine. They'll bloom in late January or February (or the normal month when yours bloom) and unless you have no snow cover, they'll survive just fine. With a zone as cold as yours, snow cover is the best friend your bulbs have got!
