Don't hill. That will only supress their growth. You want to give them room. When mature, they will be even farther out of the ground. But that's okay. I hilled mine and learned the hard way. Kim

My Redwing produce 2 1/2 to 3 1/2 inch in diameter bulbs. I plant my onions about 4 inches apart, because I do not want my onions to grow too large. I hate having to store a partially used onion because the onion was too large for a receipe. I think if I spaced the onions farther apart that they would probably grow larger. Mars looks like it is a little better adapted to your zone. Totatlly Tomatoes carries the seeds. I've grown it too but I didn't see any real difference between the two varieties. Burpee's prices have gone through the roof. When I first started gardening many moons ago, I only ordered from Burpee. Now they have priced themselves out of my budget. They carry an onion named Red Delicious but not Red Candy. I tried Red Delicious years ago but I don't remember anything about it's performance. I'd give the Redwings a try unless you are very limited on space. If I find any Red Candies I'll let you know. Karen

If you like the sweeter onions, Yellow Granex is one of the varieties raised and sold in and around Vidalia, Georgia, and marketed as "Vidalia Onions". A lot of people believe there is something special about the soil in the Vidalia, Georgia, area that enables them to produce such sweet onions. Sweet and supersweet onions, which are only good in storage for a few weeks, have almost the same percentage of sugar in them as the hotter/less sweet long-storage type onions. The difference is that the supersweets have the smallest amount of sulphur, sweets have a medium amount of sulphur and the hotter/less sweet long-storage types have the higher amount of sulphur. The sulphur is what makes us cry when we peel and cut onions too. And, onions are huge water hogs and can be up to 95% water. So, if you want to grow really big onions, give them a whole lot of water (but only if they are in well-drained soil).

Bob, I saw your post earlier but was headed out to work to check on an engine that malfed. So didn't have time to answer the way I like too. As Dawn will tell you my opinions are usually not short. Red Candy was good for me. Size was like several varied. And I mean by a lot. I just went and weighed two. One was 4 ounces and the other 14 ounces. Know I had a couple a little bigger than the 14 ouncer. So say 4 oz. to a pound. I thinned them all. And it was the whole row that way. No rhyme of reason. I like it better when I know why something does what it does. The only two real flops I had were Contessa and Red Zeppelin. Neither will be back. Walla Walla did real well. It usually does. Large and uniform size. Yellow Sweet Spanish was another that varied. The difference with it was it matured over 3 weeks. All planted out the same night. And likewise scattered through the whole row. The first ones were 4-6 ounces. The last ones were a pound or more and very good. Hard to explain. Why wouldn't weather ect affect the majority the same. I would say about a 1/3 small, a third med. and a third large. 1015Y's for me were med to large and very good. A coworker took some and got sick and didn't water for a week like he should of. He said they were small but very good taste. Candy, Big Daddy and Yellow Granex did fair this year. Not as good as they have but still good. I've got an advantage in that in my location I normally can grow onions from all 3 groups. Red Zeppelin and Contessa seem to be exceptions. I can't seem to get any size on them. Thought last year it was because I planted late. This year out early and still 3-5 ounces at the most. Good size to grill and use in roasts. Jay
