I thought maybe those metal baskets that get lined with paper for eating fries or the like from would work. But metal ones just aren't made much anymore. So I found some plastic ones, very heavy duty ones too, for just a buck each. I placed one upside down over each of the newly planted seed clusters.
Yep, it worked. Once I got the bigger leaves starting to unfurl, making the plant wobble about with menace in the breeze, I take off the bowl. Wonderful! I now have 2 bowls off and 4 to go.
And I've graduated from mere bits and bites here and there finally. Full and large butter, green leaf and red leaf lettuce, early carrots, strawberries, radishes, early onions and decent beet greens make a fabulastic salad that still tastes like a sunny spring morning.
