BEANS
Harvest snap beans as soon as the pods are big enough to suit you,
but before the seeds have begun to fill out the pods. Pick them
regularly to encourage the plants to continue producing. Pick shell
beans when the seeds have reached full size, but before the pods
start to deteriorate. Dry beans should be left on the vine to dry,
and harvested when the pods are dry and papery and the foliage has
withered.
BEETS
You can harvest up to 1/3 of the leaves without harming the roots.
Roots are best at 1-1/2 to 3" in diameter. They deteriorate if you
leave them in the ground for more than ten days after they reach
their full size. Pull them by hand rather than risk damaging them
with tools. Before storing, twist off the tops leaving about two
inches. Handle them gently to avoid bruising them. Store beets
layered in sand or peat moss in a cool (32-40 degrees F), moist
place.
BROCCOLI
When it's deep green, with the flower buds still tight, cut the
center head. If the buds have started to yellow you've waited too
long. Harvest secondary side shoots regularly to encourage continued
production.
BRUSSELS SPROUTS
Pick when the sprouts are full and well-formed. Break off the leaf
below the sprout, and snap off the sprout. The upper sprouts will
continue to form as the lower ones are harvested. To get a once-over
harvest, pinch off the growing point when the lower sprouts are 1/2
to 3/4" in diameter; a full stem of uniformly sized sprouts should be
ready for harvest in about a month. Sprouts will taste best if they
have been exposed to a light frost.
CABBAGE
Cut the heads with a sharp knife when they are firm to the touch. If
you leave the stalks and roots in the ground, you may get a second
crop of small heads. Heads can be stored in a cool (32-40° F),
moist place for 5-6 months.
CARROTS
Carrots are best left in the ground until you are ready to eat them.
They are usually ready for harvest when they are 1/2 inch in
diameter, but they can be harvested at whatever size you prefer. To
harvest, grab the greens at their crowns and pull with a gentle tug
and twisting motion. Watering beforehand makes them pull more easily.
If you plan to store the harvested carrots, trim the tops of the
greens to within 1 inch of the carrot. Leave them in the sun for
several hours to kill the root hairs. To remove soil do not wash;
instead scrub with a brush. Store carrots in a box lined with
peatmoss leaving out damaged and diseased roots. Do not let the
carrots touch each other. Keep in a cool location with high humidity.
CAULIFLOWER
Frequent examination of cauliflower is important; heads can mature as
quickly as three days. They can also take as long as two weeks after
the heads begin to develop. Tight heads have better flavor than
loose; don't wait too long to harvest in an effort to gain maximum
size. Cut the stem with a knife leaving some leaves to protect the
head. Cauliflower can be stored successfully 2-3 weeks in the
refrigerator.
CHARD
Leaves are tastiest when 6-10 inches long. Pick a few of the outer
leaves from each plant, leaving the inner leaves to continue growing.
Snip seed stalks if they appear.
CORN
Three weeks after silks appear, start checking ears. Pull back part
of the husk, and pierce a kernel with your thumbnail. If the juice is
milky, it's ready; if it's clear, it isn't; if there is no liquid,
the corn is past its prime. Sweet corn varieties, except for
supersweets, lose their sweetness soon after they are picked; the old
saying goes that you should have your water boiling before you pick
your corn!
CUCUMBER
Pick cukes frequently, before they mature, because if the seeds of
even one fruit mature, the whole vine will stop producing. Gently
twist or clip the cucumbers so that you don't break the vine.
EGGPLANT
Harvest when the skin has taken on a high gloss, while the fruit is
1/3-2/3 its full size. To test, press the skin; if the indentation
doesn't spring back, it's ready. Clip the fruit from the stem with
shears. Pick regularly to encourage further production. The fruit
will keep for up to two weeks if refrigerated.
GOURDS
Gourds should ripen on the vine; the fruit is mature when its stem is
tough and dry and its skin has become a hard, glossy shell. Be
careful not to bruise the fruit, and be aware that some varieties are
very susceptible to frost damage. After harvest, cure the gourds on a
rack in a warm, dry spot with good air circulation. Smaller gourds
will cure relatively quickly; larger bottle gourds may take up to six
months.
KALE
Avoid picking the terminal bud at the top center, so that the plant
will keep on bearing. Small, tender leaves can be picked for salad
mixes, while larger leaves can be cooked like spinach.
KOHLRABI
The young tops can be eaten as a steamed green. Bulbs should be
harvested when young, at about 1 1/2-2 inches in diameter. They can
be stored in a cool (32-40° F), moist root cellar.
LETTUCE
Lettuce is at its best if picked early in the morning, while it is
still plump with moisture. Ideally lettuce is harvested as needed,
but most varieties will keep up to two weeks if refrigerated.
Butterheads are especially delicate, and last only a few days even
when refrigerated.
MELONS
As the fruit ripens, small cracks appear in the stem where it joins
the fruit. When the cracks circle the stem and the stem itself looks
shriveled, the melon should be ready to pick. The stem should break
cleanly with no pressure; just picking up the fruit should be
sufficient to detach it. The color of the bottom surface also
provides a clue; if it changes to a deeper color, the melon is ripe.
ONIONS
Harvest scallions at any time when they reach a usable size. Harvest
bulb onions when the tops fall over and the bulbs have started to
develop a papery skin. When the tops turn yellow, go ahead and bend
the stems over to ensure that the plant puts its resources into
developing the bulb. When the tops turn brown, pull or dig the bulbs.
Gently brush off the soil rather than washing them. Cure storage
onions outdoors, if weather permits, by spreading them out and
allowing the tops, particularly the necks, to dry completely. Then
braid them or hang them in mesh bags, and keep them in a cool, dry
place.
PEAS
You should be able to start harvesting peas about three weeks after
the flowers appear; pick them when the pods are well-filled, but
before they begin to harden or lose color. Pick snowpeas when the
peas are still undeveloped. Harvest peas every day to get them at
their best, and to encourage production. Early morning is the best
time to harvest peas, since pods are at their crispest then and will
keep for longer.
PEPPERS
Peppers may be harvested as soon as they reach a usable size, or they
may be left to ripen fully to their mature color. The longer a pepper
stays on the plant, the more vitamin C it will have. Cut the peppers
from the plant with a sharp knife.
PUMPKIN
Pumpkins can be used as soon as their skin loses its sheen. Pumpkins
meant to be stored should not be harvested until the shells have
become tough, and can't easily be dented with a fingernail. Unless
frost threatens, don't harvest until the vine dies. Cut from the
vine, leaving 4-6 inches of stem attached. Never hold a pumpkin by
the stem; if a stem breaks, use the pumpkin as soon as possible,
because it will soon rot. Store them in a cool, dry place.
RADISH
Pull radishes as soon as they reach a mature size; overmature
radishes lose quality very quickly, becoming cracked and tough.
SPINACH
Each plant should have six leaves that are 7-8 inches long before you
begin harvesting. Harvest young leaves as soon as they are large
enough to use; cut the outside leaves, and let the inner leaves
remain to grow.
SUMMER SQUASH
Summer squash may be picked when the skin is soft enough to be
penetrated by a fingernail. Cut or twist off young fruit whenever
they are the size you desire. Summer squash allowed to grow too big
lost their flavor. Harvest regularly to keep plants bearing.
WINTER SQUASH
Harvest before the first hard frost. Stems should be cut at least an
inch from the fruit when the stem is drying and the skin is
hardening. Except for acorn squash, cure the fruit in the field to
dry and toughen the skins by exposing them to sun for 5-7 days. Store
at 50-55° F with 50-75% humidity and good air circulation. Acorn
squash should be kept at 32-40° F. Be careful not to bruise the
fruit at any time during curing and storage.
