Thanks Beth! I will make the corrections.
Thanx for this chart, I’m new to gardening, and all the other gardening website make it all so complicated! This is just what I wanted, a simple chart telling me when to plant seeds and transplants in NH. Great Job.
You are welcome! Stop by our new website/blog at http://www.ccognh.org for more useful information.
Glad to help! Happy planting!
I planted by Brussels Sprouts and Kale earlier last year and they did great – I’d recommend any time after April 22.
