1. My heirloom tomatoes which i've so lovingly raised since they were seeds :waa: are nice and healthy looking, but very small in comparison to storebought varieties --- I have a number of storebought variety volunteer tomatoes all over my yard and they're positively gigantic next to my heirloom tomatoes. Is this because storebought variety tomatoes have been hybrid-ed (?) to be fast growers and big plants? Or ... ??? 2. The leaves on my forsythia bushes are turning yellowish. I checked for bugs --- none. We've had quite a bit of rain, although not over the past few days. Could the rain be affecting the forsythia? Or should I fertilize? Or ... ?
