I finally managed to walk through the yard and start digging out some plants. Here is what I found
This is a protected SE corner, where I had a Trachy covered by an transluscent storage bin with some holes poked for ventilation. Next to it is an unprotected loquat and (what's left of) a citrus 'morton'.
The palm under the cover is flawless. not a single brown spot. I don't know what temperatures were underneath, but it was covered by a substantial snowpack during the worst of February.
These are two Sabal minor 'Broken Arrow'. The one on the left was protected by an inverted milk jug, on the right, nothing. They are both against a south wall. The right one looks like it could be still alive, but it's clearly more damaged than the one on the left.
On to the 7gal first year needle. I still can't reach the bottom to check the spears, but the fronds look okaish so far:
Magnolia grandiflora: owch. It was covered by 2ft of snowpack, and it did a number on most of the leaves and buds. Thankfully, the main leader SEEMS okay. Other than that, its fine. I hope the main shoot doesn't decide to shrivel up and die.
I had two first year Illicium floridanum that I TRIED to protect with inverted trash bins. but I think I should've just left them exposed. I think the sun overheated the inside and cooked them. they look half crispy, half boiled lettuce. I sure hope the stems live at least. Lesson learned.
Yucca recurvifolia has some whitening but I'll be fine
Camellia kumasaka and 'spring promise' looked great until february. They were exposed, and now look pretty crunchy. I think they will recover though
That's it for now.. The melting snow are sure to reveal more things in the coming days.
