Yep. The first can be repaired, the second compensated for, but the third is the killer. You either have to vastly move the growing season (growing in winter seems strange) or you have to learn new tricks that don't "feel right" like growing things up against a building to get shade half the day.

Composting can be a great way to improve the soil, but it takes years to really get going. But if you're going to be there for years ...

And maybe you could even get "donations" from neighbors! I know one person who setup compost jars for her neighbors to get more compostables.
