Mostly we planned, because we missed all the early spring blooms (we actually kmoved at the end of April/beginning of May), so had to wait to see what we missed.

We did plant volunteer tomatoes, the iris rhzomes we brought with us and sunflowers.}:P Later in the fall, we planted quite a few trees. Those I think we should have waited until spring for (it was a local tree steward group's fall native plant sale, so got 11 trees for less than 100.00), as a few obviously didn't make it and others are iffy, thanks to the odd winter.

Best advice is to wait a full cycle of the seasons so you know what's where and can plan accordingly.
