We're getting lots of blooms on our tomato plants now. Unfortunately I think it may be too late. The weather forecast is calling for low temperatures in 45 degree range (7 c) all week. That may be too cold for the plants to set tomatoes and, even if they do, I'm not sure that they can ripen before even colder weather arrives. That's one of the most challenging aspects of trying to grow vegetables in this climate. The optimal weather conditions in the Spring and Fall just don't last long enough. It seems always to be too hot or too cold. Anyhow, the good news is that we already have several tomatoes ripening on the vine..
