Impatiens are usually easy to grow, but sometimes they are prone to rot at the base of the main stem. This is more common in container plants although in-ground plants may do the same. It is usually caused by damage at planting time. Be especially careful when you plant out the young plants. The stems are very fleshy and watery and it is easy to bruise or damage them at planting time. Once this happens they seldom recover. In containers it is very important to have a soil mix that drains well. Waterlogged impatiens are not usually a pretty sight and may rot off. It is advisable to use a free-draining mix formulated for container growing, and be sure that the container has a good drainage hole in the bottom.
