We has a Mantz mini-tiller, Janie... Nice little tiller for smallish areas... Does not like roots or rocks, though...
Yeah, we have those warm temps headed out way, too... Maybe a day or two behind ya'll...
BTW, most PVC is used for sewage and CPVC for water... I'm surte the CPVC would be fine for planting in but you generally don't find it in anything over an 1" in diameter...
Personally, I think those gutter gardens are more for flowers... I don't think I'd want to eat anything grown in them... Especially when that plastic is out in the sun... Maybe I'm being old fashioned here???
We were just talking about growing peppers and tomatoes this morning with the hopefully impending move and figure we'll just have to grow them in containers this year and move 'um around...
