|I have planted your impatiens from seed for over 20 years in the same large bed. It's a mass planting in front of a 100ft fence in front of a pool fence. I used to plant Blitz, but you no longer offer it. So I've tried various varieties over the years, but for the past 2 years, something is very wrong. The plants grow beautifully from seed and after setting them out, they develop yellowing of the leaves and the stems seem to shrivel and die off. I plant over 150 plants and all seem affected except the ones in the deepest shade. Most are in sun for a large part of the day, but I never had this happen before. I suspect it's some type of fungus or bacteria, but wonder if I can ever plant Impatiens in this bed again. I haven't ordered my seeds yet as I'm at a loss as to what to do. This large bed is a focal point of my property and I need advice.
