Spinach
Spring spinach is remarkably more drought tolerant than it would
appear from its delicate structure and the succulence of its leaves.
A bolt-resistant, long-day variety bred for summer harvest sown in
late April may still yield pickable leaves in late June or even
early July without any watering at all, if thinned to 12 inches
apart in rows 3 feet apart.
Squash, Winter and Summer
_Sowing date:_ Having warm-enough soil is everything. At Elkton I
first attempt squash about April 15. In the Willamette, May 1 is
usual. Farther north, squash may not come up until June 1. Dry
gardeners should not transplant squash; the taproot must not be
broken.
_Spacing:_ The amount of room to give each plant depends on the
potential of a specific variety's maximum root development. Most
vining winter squash can completely occupy a 10-foot-diameter
circle. Sprawly heirloom summer squash varieties can desiccate an
8-or 9-foot-diameter circle. Thin each hill to one plant, not two or
more as is recommended in the average garden book. There must be no
competition for water.
_Irrigation:_ With winter storage types, an unirrigated vine may
yield 15 pounds of squash after occupying a 10-foot-diameter circle
for an entire growing season. However, starting about July 1, if you
support that vine by supplying liquid fertilizer every two to three
weeks you may harvest 60 pounds of squash from the same area. The
first fertigation may only need 2 gallons.
