Question of the Week:
I’m about to put an addition on my house that will require a foundation being built approximately six to eight feet from a well-established maple tree that’s about 30 to 40 feet high. The builder says there’s a chance the tree will die when the roots are cut during trenching. Is there anything I can do to help increase the tree’s odds of survival?

Question of the Week:
I’m in tomato heaven; and I just got a Vitamix high-powered blender. I am SO excited to be able to just toss whole tomatoes into that mixer! Now, when I make the sauce—adding spices, herbs, sweetener and a bit of balsamic vinegar—can I can them up without adding lemon juice? I worry that it would ruin the whole thang. (And yes, Stef did type ‘thang’.)
