Answer
Hi Patrick,
Thanx for your question.  Your question is way out of my league.  There are two things you can do.  First, you can go back to Home/Gardening and click on Gardening and then click on Vegetable Gardening.  There are several experts there who may be able to answer your question.  The other thing, is if you will tell me your state and county, or city and province in Canada or city in U.K., Australia, New Zealand, I may be able to put you into contact with a local expert.  I hope this helps.
