My impatiens are dying
I have a 20 ft. planter of them and they seem to be rotting or being cut at ground level. They have been poor looking this year. Our area has had high temp, humidity and plenty of rain. I am going to have to dig them all up and would like to put something else in there for the remainder of the growing season. What needs to be done with the soil? And what caused this problem?
Sounds like possibly a pest problem, like cutworms, in which case I have found a pesticide granule works well and doesn't harm the plants. Also, I have noticed some of mine look like this in poorly drained, compacted soil. I will be working in some compost and possibly a little sand to these areas of my garden and try again myself, once my cuttings have rooted from the healthy bed of flowers.
