Planted 2 sets of mini impatients & 1 new ginea, 3 seperate times this year & all have died where the stem meets the soil. Have been plants these flowers for 4 years now, in the same flower box.Why is this happening?

Impatiens are susceptible to bacterial wilt. The stems, at the soil level, rot and the plants suddenly wilt. This particular disease is soil borne so you'll want to replace the soil and disinfect the flower box before planting impatiens again. I think the first batch of impatiens you planted had or contracted the disease and when you replaced them with more impatiens without replacing the soil, the second and third replacement plants contracted the disease when they were planted in the flowerbox. Be sure to sterilize the box with a bleach and water solution before filling it with fresh potting soil.
