We've done this for the last three years, watered frequently but had more run off than saturation. Had peppers and tomatoes, 12 of each, got 3 small papers and virtually no tomatoes (squirrels like tomatoes). Someone told us they eat them for the moisture but tried putting watering pan out for squairels, they just like tomatoes. lol Gave up and bought tomatoes to can as salsa. This year we're buying patio tomatoes and planting them in 5 gallon buckets just to have enough for the table.
