2007 - 0
2008 - 6
2009 - 39
2010 - 90
2011 - 140
So this year's December harvest was the highest ever. In fact, it was the highest even if you combine all previous years.
What are the implications? Not much...just that SunGold(1) took off very late in the year. We harvested 129 SunGold(1) tomatoes this month. And they were good!
If anything, this is an indication that it's good to plant sweet peas and sugar snap peas in the fall. The SunGold(1) took off when it "found" the soil previously used by the peas last winter.
