Tanya,
Just want you to know that you can PM me anytime with questions about gardening. I have been a horticulturist most of my life, and worked for the UNL Extension service for many years.
All the advice you will get from others is going to be some of the best kind.....the kind you get from experience. I would encourage you to check out your Extension offiice in your county ....they may have wonderful publications (maybe online) to help with specifics in your area.
Your area should be coming into the time when you can grow crops that like the cool weather. Spinach, peas, snap peas, lettuce, green onions, broccoli, cauliflower, cabbage. These like to mature in cool weather, and usually fade when the weather turns warm.
The others you mentioned...corn, squash, black eyes (which are actually "beans" ) and need warm soil and weather to grow well. I have a suggestion for growing sweet corn with great success if you are interested. It takes a little more work, but it allows you to have a good germination rate, and no open areas in your corn plot. Also consider planting your corn in successive plantings so it doesnt all mature at one time. Let me know if you are interested, and I will PM you this....or share on the thread so other board members can see also. Just dont want to hog the thread or anything.
