I’ve had a garden for 4 years and I know it can be tricky at first to figure out what will grow well in your area. I am in North Texas and my go to site is Aggie Horticulture
If you live outside Texas you will find some great information on these sites:
Mother Earth News
American Horticultural Society
My Advice To First Time Gardeners
Purchase the 2 books below and combine what you learn in both to build your garden and maintain it. They are simple to read and easy to understand.
