Dream Garden: 2 years away!

We own a piece of property on the east coast (Zone 6a) and are planning to move there in just 24 short months. The kitchen garden is my pet project and I have mapped it out on paper.

I have been researching from local gardening books and, as time gets closer, will join a local garden club (though most seem geared to flowers, in which I have little interest-mostly you can't eat 'em!).

Last year, we put in a well-protected asparagus bed. Well-protected because we share the land with white-tail deer, rabbits and chipmunks. Asparagus (from seed) because it will take 3 years until harvest.

We are also reviving some ancient Macintosh and Russet apple trees (the land was once an orchard). We have pruned back into shape and are fertilizing.

Beyond my favourite annuals (peas, tomatoes, brussels sprouts, beets, carrots, turnips, potatoes), I have some perennials in mind: blueberries, raspberries, rhubarb.

Given that we can't be there more than 2 or 3 times during the growing season and maintenance is a once-a-week hour or two from a local organic gardening student team, can I reasonably make an advance on anything beyond the asparagus? planting? bed prep? building enclosures?

What else could I do to feed the need to plan?
