I wouldn't have believed it, but this year with a late cold snap, and then onset of heat and rain. When other tomatoes barely stayed alive, this Brandymaster Pink is thriving and mostly unaffected. With very little yellowing from excessive water, and virtually no sign of disease. I do spray and plant organically, and this tomato is rivaling the production of my Big Beef Hybrid plant. The regular Brandywine has one small fruit on it, so there is a huge difference in my opinion...not even the same plant in any way. All of the fruit are still green, but there are loads. Haven't tasted it yet, but I'm hoping.
