Q.What kind of spray would I use to kill weeds in celery, and what type of manure to grow celery
Hi,
I am a vegetable grower, and I grow an acre of carrots, and an acre of turnips. I would like to try out growing celery, as it goes well with a carrot dinner. What type of spray would I use to kill weeds in celery, and how would I apply it. Also what kind of manure would I use, and how many bags to the acre.
