Trellises. I'm excited to build my own garden trellis. The materials and location are already pre-prepared in my mind. It would look like this: (taken from one of my favorite blogs, NW Edible).
Compost. Maybe worms, maybe just a mixture of leaves and food scraps. Enough said. Moving from apartment to apartment doesn't exactly facilitate the adequate waiting period for a proper compost. If you have a house and a garden though, you should think about it!
Raised bed (grow majority of our own food). And I would practice crop rotation to make sure we never leech out nitrogen (or other nutrients from the soil). Kale, beans, tomatoes, squash, corn, potatoes... the list goes on and on. Bacon production would have to be outsourced.
Grow tomatoes to make homemade tomato sauce. Normal tomatoes, purple tomatoes, Brandywine tomatoes, San Marzano tomatoes, I would try them all. Then I would cook and can all of those tomatoes to store for the winter, like a squirrel. But a sophisticated squirrel. I've already bought reusable canning lids - so reality is slowly catching up with this dream.
Contribute leftover vegetables to food bank. Use what we need, donate what we don't. Maybe the neighborhood would also have a veggie swap, that'd be awesome!
Endless kale. Imagine yourself in a forest of kale. Lacinato kale, red russian kale, green leafy jack kale... and you can pick whatever you want anytime of the year. It's so hardy it'll grow just about anywhere that isn't too hot. Yes, I want that.
Mostly, a permanent place to put down roots. Then that kumquat tree I grew from seed can go in the ground. Blueberry bushes would have a home (I have three kinds - can't help myself), and could start to settle. I could grow apples, figs, lemons, and plums (all depending on the region of course).
What do you dream of?
