Or is your weather hotter? Does your soil hold more, than less than,
or just as much available moisture as mine? Is it as deep and open
and moisture retentive?

To help you compare your site with mine, I give you the following
data. My homestead is only 25 miles inland and is always several
degrees cooler in summer than the Willamette Valley. Washingtonians
and British Columbians have cooler days and a greater likelihood of
significant summertime rain and so may plant a little closer
together. Inland gardeners farther south or in the Willamette Valley
may want to spread their plants out a little farther.

Living on 16 acres, I have virtually unlimited space to garden in.
The focus of my recent research has been to eliminate irrigation as
much as possible while maintaining food quality. Those with thinner
soil who are going to depend more on fertigation may plant closer,
how close depending on the amount of water available. More
irrigation will also give higher per-square-foot yields.

_Whatever your combination of conditions, your results can only be
determined by trial._ I'd suggest you become water-wise by testing a
range of spacings.

When to Plant

If you've already been growing an irrigated year-round garden, this
book's suggested planting dates may surprise you. And as with
spacing, sowing dates must also be wisely adjusted to your location.
The planting dates in this chapter are what I follow in my own
garden. It is impractical to include specific dates for all the
