The obvious purpose of quick hoops is freeze protection.
However, I also find it useful to split up the garden into use-now and
use-later areas by covering up the latter. Usually, out of sight, out of
mind is a bad thing in the garden. But when you're stockpiling food for
year-round use, a hidden harvest waiting for you in December can be a
plus.
To that end, I covered
1.25 rows of kale, one row of lettuce, then about half a row of parsley
and a quarter row of mustard greens Tuesday. If Mark's tri-tunnel
works out, that'll sock away another row of kale and most of a row of
brussels sprouts. A full winter feast! And we have roughly the same area
left uncovered for November harvest. This is such a bountiful time of
year.
