    I am in Revelstoke, BC. I have started a new green house this year and
    have planted tomatoes and red bell peppers in a bench-top box (approx 1.5
    feet deep). I used garden soil mixed with mushroom manure and peatmoss.
    The plants are all doing great (we've had hot temperatures for the last
    2-3 weeks). The peppers are very healthy and have large dark green
    leaves, BUT... after the flowers are done, the stems turn yellow and fall
    off. Could it be that I am overwatering (with the heat, I've been
    watering everyday), or are they perhaps not getting pollinated. I've
    tried manual pollination by rubbing a q-tip inside the open flowers, and
    after the flower petals die, I see what looks like a tiny fruit, but they
    all turn yellow and fall off the plant. Very sad!!

    can you help?

    Thank you,
    Jennifer Lange

    Jennifer--do you happen to have a thermometer in the greenhouse, recording max/min temps preferably?

    My first suspicion would be either cold overnight lows, or daytime highs getting into the dangerous range, very easy in a house with little shading and/or limited venting. The healthy green foliage is one good sign that you probably have the root zone going well...(some might suspect too much nitrogen but I've never seen that with peppers...as long as they are producing flowers I think the nutrition is adequate, more likely something physiological rather than nutritional).

    thanks. I think the heat may be the problem. some of my other plants were suffering during the heat of the day, but in the form of wilting when they had plenty of water. I will get a thermometer and start planning better ventilation.

    thanks again.
