geranium: did I just kill them?

Geraniums are fairly hardy plants, and they should be OK with what you have done, it's said in some of my old gardening books : Geraniums like to be kept fairly dry, over watering will kill them, if any shoots seem to be dead, after a few days it would be a good idea to cut the down to the base.

You might have sunburned them. Or they just got dehydrated. If just dehydrated, a good watering will snap it back to life.

Plants that are not used to being out in the full sun (even if they get full sun through a window) can get sunburned if they aren't acclimated to the full, direct sun over time (you can even sunburn a cactus that way). The sun actually damages the chlorophyl in the leaves, turning them kind of whitish in the affected areas. They eventually turn brown and drop off.

But, a sunburned plant can be nursed back to health. Keep it in the shade, in indirect light for a while. Don't try to fix it with excessive watering. That will hurt it more. Eventually the leaves will come back. Then you can get it reacclimated to the sunlight.

New enhance reducing will root in water in 5-7 days. Sorry Fluff, you do no longer could desire to enable cuttings dry - shrink, to water as we communicate. substitute the water if it gets cloudy. Grape leaf geraniums won't root in water, could desire to apply rootone, place in damp potting soil.

Geraniums are pretty sturdy and hard to kill. I say fertilize them as a treat! :) It will help them get a perk!

Don't overwater or fertilize. Plants under stress don't do well with fertilizing.

I think they will fine soon.
