VEGETABLES
Fall & Winter Vegetable Gardens
For Western Washington
Western Washington has generally cool
summers and mild winters in most locations. At altitudes below 1000'
frost in the soil is rare and can usually be prevented with a light
mulch on the soil surface. This combination of weather conditions
allows home gardeners to produce satisfactory crops of many vegetables
for fall and winter harvest. However, since the fall and winter months
are normally quite wet is important that gardens be well drained.
The following vegetables can be planted in summer or early fall for
winter and early spring harvest.
BEANS
Plant Bush beans until late July to produce a good crop before frost.
The plants develop more rapidly in the warm summer months than in
early spring. Pole beans require more time to develop and should be
planted by July 1 for a fall crop. Plant Fava or Broad beans the second
week of November for June Harvest.
BEETS
Beets can be planted until August 1 and produce a dependable crop.
If you want beet greens, plant until September 1.
BROCCOLI
Direct seed until mid-July and transplant until mid-August. A fall
broccoli crop will usually continue producing past Thanksgiving and
sometimes until Christmas.
BRUSSELS SPROUTS
Brussels sprouts require a slightly longer growing season than broccoli.
Direct seed by July 1 and/or transplant by August 1 for a dependable
fall crop. In protected spots harvest can continue into mid-winter.
CABBAGE
Ballhead cabbage for fall harvest requires the same culture as Brussels
sprouts. Treat Savoy cabbage as broccoli. Fall cabbage crops will
hold in the garden for prolonged periods and can be harvested in to
early winter. Jersey Wakefield cabbage can be seeded from September
1-15 to winter over.
CHINESE CABBAGE
Chinese cabbage is best planted in late July for a fall crop.
CARROTS
A fall crop will keep in the garden until used. Plant by mid-July
for wall and winter harvest.
CAULIFLOWER
Culture for a fall crop is the same as cabbage or Brussels sprouts.
CHICORY
Witloof chicory or French endive can be planted until mid-July. Roots
can be dug in late fall, placed in a box of moist soil, covered with
sand and forced in a warm room for winter greens.
CORNSALAD
Cornsalad, (lamb's lettuce or fetticus), can be planted early September
for fall use or late October to winter over for early spring use.
ENDIVE
Plant either curled or broad leaf types until mid-July. In October
tie leaves together to blanch hearts. A light mulch of straw will
protect it from early frosts and permit harvest into winter.
GARLIC
Plant garlic in late October to November 10 for early summer harvest.
KALE
Plant seeds in July and transplant until mid-August.
KOHLRABI
Sow seed until mid-July for fall crop. Both white and purple varieties
are suitable. Harvest when stems are 1-1/2" to 2" in diameter, before
the stems become woody.
LEEKS
Plant in spring but hill or much in fall and harvest as needed all
winter.
LETTUCE
All types of lettuce are suitable fall crops. Sow head lettuce and
Romaine in July. Leaf lettuce varieties can be planted until mid-August.
MUSTARD GREENS
Mustards germinate and grow rapidly. Mustard can be seeded through
September to produce fall greens. Bok Toy (Chinese mustard) should
be seeded by mid-August.
ONIONS
Onions for green or table onion use can be seeded until mid-July for
fall use. Seedlings made in August will normally winter over for spring
use. Onion sets can be planted anytime during the fall and winter
if the soil is well drained and workable.
PARSLEY
Can be seeded in early July for fall and spring use.
PEAS
Can be planted in early November for an early June crop. Green peas
and edible pea pods (sugar peas) can be planted until mid-July. A
moderate harvest can be expected in the fall.
RADISHES
Early varieties can be planted throughout the growing season until
mid-September. Winter radishes (oriental types and Black Spanish)
should be planted in July and harvested all winter.
RUTABAGA
Plant in early and mid-July for fall and winter harvest. Leave them
in the garden and harvest as you need all winter.
SHALLOTS AND CHIVES
Plant or divide both of these in late October or early November each
year. Leave in the garden the year around and harvest as desired.
SPINACH
Plant spinach in mid-August for a fall crop. Plant in September to
winter over for an early spring crop.
SWISS CHARD
Chard planted by mid-July will produce a fall crop or planted in late
August the plants will winter over and produce and an earlier crop
the following year than spring planting.
TURNIP
For mature roots plant turnips by mid-August. For greens, plant through
September.
COVER CROPS
In Western Washington it is normally a good practice to seed garden
areas which are not occupied by fall and winter crops with a cover
crop. Cover crops such as crimson clover or vetch or a combination
of annual rye and vetch will benefit the garden soil by conserving
nutrients, reducing weed growth and preventing erosion. A fall cover
crop becomes a valuable green manure crop to plow or spade under the
following spring. Till in the cover crop at least two weeks prior
to planting.
Try to choose only early maturing
varieties of all these crops to assure enough time for them to mature
before frost slows them down or halts growth entirely.
