We moved from a house with virtually no windows to a house with a 350 square foot sunroom.
We went from 2 tiny plants to 27 medium and large plants.
We have more money than sense.
Plants were all doing great until the temp outside dropped to near 0C. (I did check that they were all hardy enough to survive down to 5C.)
I had intended to put in a space heater (oil radiator) to keep the temp at at arond 10C but I waited just a little too long.
Also, I watered them all just before this temp drop (which I now think I should not have done with the onset of dormant season. The water still has not evaporated after two weeks.)
Anyway, within 24-48 hours every one of my plants has wilted almost completely. Many have turned grey ie. no more chlorophyll. Most of the rest have turned black. Many of them are still quite wet (i.e. I guess frost got them before they could dry out). About 50% of my plants have at least some healthy green on them.I've since made a 6x4 greenhouse out of 6 mil clear "moisture barrier" over a frame to accommodate them all and have installed a couple of heaters nearby to see if I can keep them around 10C and hopefully to dry them out a little?
Presumably, I have to cut back everything that is not bright green. Even the stuff that's still somewhat turgid with water? It's not going to green up is it?
Here are my big concerns now:

Here are my big concerns now:
- Is it too late to save these at all?
- Can it get (dramatically) worse from this point on if I do nothing more?
- Will the roots survive to regrow when it gets warm?
- Do I need to take remedial action sooner rather than later? (Or can I jut wait for spring?)
- Is all the black due to mold?
- Am I making things worse by crowding them together where a potential mold can get worse?
- If the soil is also wet (because it's not being taken up or evaporating), will it harbour a lethal bio-load of mold, killing any remaining roots?
- Would a grow light over my makeshift greenhouse help anything survive if not recover?
- Short of hauling everything into the house where it's 20C, what is my best course of action, while leaving them in the sunroom? What temp do I need to keep as a minimum? How much light? Do I need to repot them in an attempt to dry out the soil?
