I have potted double impatiens that I would like to save during the winter. I live in the Midwest. Is this advised?
You can try bringing them indoors for winter but just in case, I would recommend taking cuttings of the plant to ensure their survival over winter. This article will help with that: https://www.gardeningknowhow.com/ornamental/flowers/impatiens/impatiens-rooting.htm
My impatiens suddenly wither within 3 days. I think something is eating them, but I have not actually had a chance to scratch around and see. If snails as I suspect, what can I do about it? Or if it's something else, is there a general way that would help?
Thanks,
Dorethea
It sounds like there may be a root rot or a bacterial wilt to blame. This article will help: https://www.gardeningknowhow.com/ornamental/flowers/impatiens/impatiens-problems.htm

Impatiens walleriana are being plagued by a 'new' disease called "impatiens downy mildew". The following article should be helpful: http://www.mnn.com/your-home/organic-farming-gardening/stories/impatiens-disease-becomes-hot-topic
This article is a pdf from an industry giant in the horticultural industry:

Reputable growers should be suggesting that consumers substitute begonias, New Guinea Impatiens or petunias for impatiens walleriana.
I live in northwestern PA and I have this cactus that I grow year round, outside in summer, inside in winter. It does very well. I also always put in impatiens. Had one of my cacti sitting near my impatiens 3 yrs ago, brought it inside in the fall. I thought weeds were growing in the cacti, but I let them go to be sure. Well, sure enough there were impatiens growing in it. I have impatiens year round and I do nothing special for them than I do for my other plants. Is this uncommon for impatiens and should I be doing anything special for them? I have to keep cutting them down, have started other plants, and they are getting ahead of me.
I had the same thing happen many years ago. This is fairly common. Impatiens are a type plant that "throws" it's seed when they are mature. As a 'survival of the fittest' trait, the further a plant throws it's seed, the better it's chances for more plants. I've had some of the prettiest blooming ferns you've ever seen! While impatiens and cactus reequire different culture in nature, it is amazing how well they can live in the same container for a "brief" time. Enjoy your roommates that prove opposites attract.
All the leaves of my impatiens are being eaten. I don't have beer to put by the plants and I have animals, so no poison. What do you suggest? Thanks. yvonne

If you are sure the culprit is snails or slugs, you could spread crushed egg shells or sharp sand around the impatiens planting. Also, diatomaceous earth will help control these pests.
Something is wrong with my soil. All of my impatiens are dying. At first I thought it was snails or slugs, but it's the soil. Randy Lemmon talks about some liquid stuff starting with an M, but I can't remember the name. HELP.
Are you sure it is the soil? Downy mildew is becoming a major problem with impatiens. This article might help: http://palmbeachcountyextension.wordpress.com/2012/01/26/downy-mildew-on-impatiens/
Planted impatiens from seeds and they came up but seem to have stopped growing. Should I keep them in the lights or move them away from the lights?
Keep them under the lights, and give a one-quarter strength fertilizing. Alternate water and fertilizer, keep plants barely moist to help prevent root problems and fungus gnats.
When is it safe to plant impatiens again after last spring's fungus problem?
