Hi Shirley--So glad you like the article. Thanks for asking to use it; that's a nice compliment! I am checking with Site Admin on that. I'm not familiar with the rules. We should have an answer very soon so you can plan your newsletter accordingly..
The answer is that we can give permission for reprinting articles if they are not
reprinted electronically, just hard copy. Also, as long as it is not
done on a large scale; garden clubs, school classes and family
newsletters are all ok. City newspapers are not.
If you just want to use part, I believe it's OK for you to give the Dave's Garden site link to the original and take a selection for hard copies for insertion in the newsletter.
I hope this helps!
