This year I planted Roma tomatoes in the same pot that I used for beefstake tomatoes last year. Did not add any fresh potting soil this year. Added a bit of organic manure and powedered egg shells plus regular dose (once in 2-3 weeks) of fish fertilizer.
Found cracks on several tomatoes. Tells me that the plant needs more watering.
Used the tomatoes for Roasted Ricotta Roma Tomatoes (RRRT) immediately after they were harvested.
