Hi Carrie, the bermuda will not start to green up until April or so. Any temps freezing will set that back. I have dwarf gardenias that were badly damaged by a late frost a few years ago. I thought they were gone, but they came back. Yours probably will to, just give them some time. With any new plantings, they can be sensitive. Make sure to keep them watered if it doesn't rain.

Hi Bernard, I hope I don't repeat something because I only got about halfway through this thread before I got sick of reading and decided to go ahead and post. #1. I don't know where the idea come from that calloused roots are good. Callouses can't absorb water. It's dry scar tissue that keeps in/out moisture, thereby protecting broken stems and so on. When a plant's roots are partially exposed by wildlife digging, etc., the exposed portion callouses to keep the plant from dehydrating, but that calloused portion will never absorb water again. We don't want roots to callous (except maybe Bonsai growers who like to expose some roots over a rock or something). Putting a root system into dry mix is never good for it. I challenge anyone to prove how dehydrating or callousing a root system can possibly be good for it. The previous poster who said the dry mix will dehydrate the plant is correct. Always use damp mix for re-potting a healthy root system. If the roots are dead, it might be a different story. #2. As you've already learned, it's easy to under-water gritty mix. Since it's pretty close to impossible to over-water grit, I'm with the posters who say to soak it deeply and often. If you're paranoid, soak it daily, or even twice daily, but then give the pot a quick, little down-up motion to dislodge any perched water. That way it'll always be just barely moist. If it were mine, and planted in grit, I'd just water every day or two until the roots are well-established. As one who has killed off whole, healthy root systems by under-watering grit (once weekly), I feel confident in telling you that you're extremely unlikely to drown a plant in grit. I'm watering my succulents daily right now, and some are STILL too dry. BTW, Danny, I think mentioned he prefers soil for jades. I don't disagree with him. The one I have in soil has grown much better than the ones I have in grit. Furthermore, the Aeonium I had in a 1:1 soil:pumice mix has a huge, beautiful, healthy root system. The big one in grit has puny roots. These aren't experiments with standardized variables, so something else might be going on, but for now, I'm also not certain that grit is always a better medium.

Be sure you cut away every bit of soft tissue. If you save partial pads, cut into healthy tissue to be sure you've cut away all mush. Bacteria grow rapidly in the damaged tissue and can sometimes spread to healthy tissue when a plant is stressed or dormant, so be sure to get rid of that stuff. Opuntia species are fantastically resilient and easy to propagate. I have seen Opuntia pads root from between blotter papers in a plant press left over the holidays in a cold, dark botany lab. You needn't keep them damp. They have adequate moisture in the pads to feed new root growth, and they can't absorb moisture through the "skin" anyway, so my feeling is that adding moisture will only increase the danger of rot. Personally, I think it will root just fine if you lay it on top of dry soil. Just be sure the damaged portion scars before you let it get at all damp. Some Opuntia species are very cold tolerant. Others aren't. There is one species that grows wild around Boulder Colorado- Opuntia compacta maybe. That isn't your species, but it's easy to see why you thought it might survive such intense cold. I hope you can salvage some. It looks like one of the more attractive Opuntia.

Genna, that's great. but I don't think there is going to be any way to help you with that kind of answer,,( It looks dead...Is that out of the pot? How long did you let it stay that way? Is it in a pot now? What kind? What kind of soil? What kind of light? When or how do you know when to water? Do you fertilize? What do you use? Do you let it dry out to a wilt? Do you water when the soil is still moist? Where do you live, well what state? What growing Zone? Did you ever grow it outside? What kind of window do you keep it in if in the winter? Just a few questions
