Brussels Sprouts

_Sowing date:_ If the plants are a foot tall before the soil starts
drying down, their roots will be over a foot deep; the plants will
then grow hugely with a bit of fertigation. At Elkton I dry garden
Brussels sprouts by sowing late April to early May. Started this
soon, even late-maturing varieties may begin forming sprouts by
September. Though premature bottom sprouts will "blow up" and become
aphid damaged, more, higher-quality sprouts will continue to form
farther up the stalk during autumn and winter.

_Spacing: _Make each spot about 4 feet apart.

_Irrigation:_ Without any added moisture, the plants will become
stunted but will survive all summer. Side-dressing manure or
fertilizer late in September (or sooner if the rains come sooner)
will provoke very rapid autumn growth and a surprisingly large yield
from plants that looked stress out in August. If increasingly larger
amounts of fertigation can be provided every two to three weeks, the
lush Brussels sprouts plants can become 4 feet in diameter and 4
feet tall by October and yield enormously.
