Just purchased Impatiens plants. Being "late" in the season to start, the plants are single stems with no fullness. If I pinch the plants back, can I thereby force them to become fuller instead of single stems?
Yes, this works well. Just nip (aka pinch) the very top end of the stem and this will kill the terminal bud and force the secondary buds to grow as branches.
I have been planting impatiens in front of my house in beds for several years. They always did great. The last two years they have been terrible. They are not growing and the leaves are yellowing. We planted at the end of May. We put down fresh topsoil and after planting they were mulched. They were fed twice with Miracle Gro. I know the sun and shade pattern is ok because they did well in previous years. I usually water every other day unless the weather is exceptionally hot. Any ideas?
It sounds like they have chlorosis. Most of the time, this is cause by a lack of nitrogen or too much phosphorus, but since you have been fertilizing with a macronutrient fertilizer, I suspect that the pH may be off. This article will help:
I have 12 window boxes of impatiens on my deck, planted late April, and they are quite high and leggy. . . beginning to fall over. Can I cut them back to shorter stems, and will they regenerate and continue to bloom? I realize cutting back will remove all blooms, but its still early summer. If they do regenerate, about how long should it take to see new blooms?
Too much fertilizer can cause leggy plants and reduced flowering. Pinch them back to 6 inches and they should regrow as bushier plants. Leggy plants are also fixed by trimming off the plant so that it looks more like a bush shape.
I have impatiens planted just inches apart and were full of blooms when I planted them in May, somewhere around Mother's Day. They were planted in good topsoil in complete shade, but get a little bit of morning sun. I have been watering them regularly at least every other day unless it rains. They are not spreading and don't have very many blooms on them. My daughter has hers planted in the shade, purchased them at the same place, get watered every day and hers are full of blooms and are spreading together. What is my problem?
Your impatiens may be getting too much water, not enough light or need another dose of fertilizer. While impatiens do grow in shade, they still need some light. You may find the following article helpful:
I planted impatiens on Memorial Day and they were doing well until a few days ago when they started developing brownish spots on the leaves and began to die. They are planted in 2 separate locations. Could you please tell me what happened?
Sounds like your impatiens have a fungal disease commonly called leaf spot. It's carried by insects, usually thrips, and there's no guaranteed treatment. You can try an all purpose fungicide, but your best bet may be to pull and destraoy the plants. Sorry.
Rabbits and/or squirrels are eating impatiens and have pulled the roots clear out. How do you stop this, and do deer also eat impatiens?

Note: Deer will eat anything.
Try sprinkling cayenne pepper on the plants. That should take care of them. If not buy Critter Ridder. That will definitely work.
I have bought and grown impatiens for many years and never had any problems. This year they're planted in pots using Miracle Grow Moisture Control potting soil, as I am now in Nashville, TN. They have plenty of buds but are not blooming. I used Miracle Gro starting fertilizer and then regular Miracle Gro fertilizer since then every other week, but nothing except buds.
The most common reason is that there is not enough light. They do need shade but bright shade..........if in too dark of a location, they often bud but do not blossom. Hope that helps.
