I'll admit that I'm
unimpressed by the lettuce this spring in the cold
frame. I suspect the issue is temperature extremes (too hot when I
forget to open the glass, too cold when I forget to close the glass)
combined with moisture extremes (too dry most of the time, then swamped
when water gushes off the roof and onto the baby plants). The
over-wintering arugula, on the other hand, is going gangbusters.
Actually I planted this
arugula's parents in October 2015. The plants grew, went to seed last
spring, then self-sowed replacement rosettes. I picked leaves off and
on all winter and am now harvesting the rapini heavily to fill spring
omelets. At some point, I'll let the poor plants go to seed and repeat
the cycle...but I'm enjoying the meals too much to let them go quite
yet. Instead, I'm just enjoying seemingly endless arugula, all from one
small packet of seeds sprinkled on the ground eighteen months ago.
