>>1089863I have an ancient cultivar like that, but is pear shaped (pic). They are also fairly sweet. Cherry cultivars seem to be extremely prolific and grow like mad. I think it may be because they have less harvest weight in fruit so more energy can go towards vine growth. If you want to fertilize without store stuff read up on "compost tea" and "manure tea". You can also use a mixture of 1 part water and 1 part plain coffee.
>>1089874Homegrowers also have the option of restricting the water, prior to harvest for a few days, in order to trigger a chemical response, in the tomatoes, which makes them more flavorful. Thus, a store bought tomato the same cultivar of a homegrown one can taste "watery" in comparison, if that technique is used with the homegrown one. Often times, the homegrower does this unknowingly. The ones in the stores are normally grown with hydroponics on a timer so they never go without water for an extended length of time.
