While catching up on a few of my favorite blogs this afternoon I was reminded of a critical broccoli seedling step that I had forgotten about:
-- pinching off the first set of leaves after the true leaves have started growing --
The result is less "tippy" broccoli seedlings and the energy is focused on those true leaves.
I also use a tablespoon to place some additional potting mix around the base of the stem, while provides a llittle more stability for the sometimes "tippy" stems.
I am happy to do this since it is pruning, not thinning, which I hate. Thinning seedlings makes me feel awful. I dreaded it - it makes me feel like a veggie killer.
