In Ellen's article about growing celery, it talks about blanching. It sounds like staking or supporting. Is that correct? If not, what is it and what is the purpose? Why is it not called staking? Thank you.

It's not called staking, because it isn't staking. Blanching means covering the vegetable, or parts of it, from sunlight. This keeps it a lighter color and usually more tender and sweeter. It traditionally is done by covering the plant with something (mulch, cartons, etc), tieing the leaves over the head (cauliflower), covering with mounded dirt (leeks, asparagus), etc. Since the plant won't get as much light, total photosynthesis won't take place, and there will be a loss of some vitamins; light veggies are rarer and a delicacy.
