I spotted the first tomatoes on one of my tomato plants this evening.
I'm trying a new growing method this year. Last year I planted tomatoes in the only patch of dirt available to me, but there wasn't enough sun. In much of the San Francisco Bay Area, summer is foggy and cool and autumn is sunny and hot. So when the sun was high in July, theoretically able to reach marginal garden areas, Oakland tomato vines still shivered and waited for warmer days. By the time it warmed up in September (in truth even autumn wasn't very warm), there wasn't enough sun in the garden. So, a disappointing tomato crop last year.
But I'm trying a new strategy this year.
I'm growing tomatoes upside down on my south facing balcony. I rooted two plants in 5-gallon buckets hung from the rafters. The buckets have small holes cut in the bottom, with a few extra drain holes drilled around the bottom edge. The plants have grown vigorously since I transplanted the small starts a month ago into organic potting mix.
This spot is under an eave, so it will get less than ideal sun for the next month or so. But by the time it warms up around here the sun will be lower and the plants will get sun better than half the day, just in time to ripen up all that green fruit.
