Q: I’ve heard you talk about pre-emergents on your show and I was wondering if I could use one on the plot of ground where I will be planting my fall patch of turnip greens and spinach. Every year, the weeds over take the patch before the greens are gone, but it is impossible to pick the greens because there are so many weeds. We will need to plant by late September or Early October. Can I put a pre-emergent on the spot and then plant in a few weeks? If so, what do you recommend?

A: See the ‘Preen’ ™ website for more information.
