2023 In what's a common refrain this year, I had reduced production in all my tomatoes, probably due to higher than normal smoke levels in the air. Later and lower production for me than usual, but still about 4 lbs per plant, with an average fruit size of 97 grams. Still no cracking or splitting. I grew it in a 5 gal pot for the first time ever, and while it enjoyed the heat of where it as, the pot may have hampered growth.
2017 One of my earlier producers this year - first to set flowers and second to ripen. Did well with irregular moisture and high daytime and nighttime temps. No cracking or splitting. Some family that also grew this variety mentioned how amazing their harvests has been as well.
2011 Delicious and sweet fruit. Squat, flat shape with heavy pleating. Doesn't suffer at all when it's dried out, as it was in the driest part of my garden and suffered from irregular watering from time to time, but never cracked, and plant didn't suffer any stress. Even sets fruit at lower temperatures when the rest of my tomatoes were dropping their buds. If it gets too wet the plant does seem to abort fruit. A definite new favourite of mine!
