Can you remove it by pulling up on what's left? Mine are soft fuzzy green piles now, long gone is the brown and I'm in the same zone, so I'm wondering if yours is still viable??? Crossing fingers!

Now that Spring is almost here

==>>> when in doubt.. give it a little more time.. to see if you can see any new growth .. like expanding buds ...

the plant will usually give you direction .. if you have the patience to wait for it to show you ...

i dont recall where you are ... but a lot of damage can be done.. if you get the fever too early ... including compacting soil by walking in your beds when they are too wet ....
