If you planted garlic last fall, as we did, by now you should be seeing vigorous green top growth. How vigorous can depend on many things. Variety of garlic you planted, clove size that was planted and soil conditions are all major factors. If You are not seeing vigorous green growth you will probably need to add some nitrogen fertilizer to give it a boost. It is recommended that nitrogen only be given up until the time that the bulbs start forming. This article explains that bulbs start forming around the time the ground temperature reaches around 60 degrees. http://greyduckgarlic.com/Southern_Garlic_Grower_Guide.html Another article I read said that bulbs start forming around Memorial day. That article I’m assuming was referring to growing garlic in a cooler, northern climate like ours.
This time of year it is also important to make sure that garlic is getting enough water. This year our problem has been too much water, since we have had “April showers” in January, February, March, April and the first part of May. Although our garlic has shown signs of being stressed with some yellowing of the leaves, due to too much water, we are optimistic that we will have a decent crop.
It is recommended that garlic receive 1 inch of water a week during dry periods up until about two weeks before harvest. At this time we have no intention of watering the garlic anytime soon.
Keeping garlic weeded is the other chore that needs to be done from now until harvest. “Weed early, weed often” seems to be a garlic growers mantra as I seen it written in more then one article that I’ve read about growing garlic. Last week my husband and I spent several hours on two separate days weeding the garlic. Weeding garlic is something that needs to be done by hand, especially if it is planted with several rows close together, like our is. At this point the weeds were still small and with the ground being wet the weeds came out easily. I believe this is the reason for the “weed early” advice. As bulb formation begins making sure the garlic weed free is even more important, as garlic that is crowded by weeds or roots of weeds will produce smaller bulbs. I do expect that we will be on our hands and knees weeding the garlic a couple more times before harvest. 🙂
