Does the practice of removing older leaves on growing swede encourage the plant to grow larger? This is something that I believe was recommended by a professional garden presenter on BBC Television about 3 years ago and I would like your comments please.

Personally, I've never heard about removing the older leaves to promote growth. You could experiment with a few plants.
