Here's what happened. My girlfriend and I brought our many, many plants inside two months ago. We have a kind of weird little front room that's basically a small enclosed front porch. It's north-facing, unfortunately, but has windows and skylights, plus we've rigged up some extra lighting.
However, it's been SO cold that we started to grow concerned that our plants weren't getting enough warmth. So, uh, when she suggested we try a space heater, I said, "Sure."
And THEN what happened? Well, as you might know if you've ever tried this (or might imagine if you have an iota more sense than we did), the plants that were directly in the path of the warm air... Uh... Cooked. Literally, I think. Here's a picture of my poor, previously dapper little attenuata:
My quadricolor fared a little better. You can tell from these pictures that it was in the path of the heater, but not the direct path. Basically, the warm air (which didn't feel THAT warm coming out, I swear) cooked the portion of the leaves in its path.
I've never had an agave with serious leaf damage like the quadricolor before. I need your advice... Better to let it repair on its own (I'm guessing that the damaged parts will just shrivel up and die eventually, but that the rest of the plant will survive), or better to cut away the damaged part? And if so, how? Cut away the whole leaf? just the damaged portion?
Eagerly and shame-facedly awaiting your advice...
