Could be both of those; could be a year's worth of good root development; could be 'just because'!

So, whatcha gonna do with all of those lemons?

LOL I will zest and juice till my hands hurt then do some more. I freeze a Meyer lemonade syrup that you just add water to make about the best tasting lemonade ever.

I ran across a recipe for Meyer Lemonade and fresh pineapple sorbet that will get a go this year.
