ASPARAGUS
|
Asparagus can be harvested the third year after planting crowns, but do
not harvest for more than one month the first time. In the following
years, the spears may be harvested in May and June. Harvest spears 5 to 8
inches tall by cutting them or snapping them off. Cutting may damage some
spear tips that have not yet emerged from the ground. To snap a spear,
bend it from the top toward the ground. Asparagus deteriorates rapidly
after harvest. If it is not eaten immediately, it should be processed or
refrigerated.

LIMA BEANS
|
Pick lima beans when the pods are well-filled but before they turn
yellow. The end of the pod should feel spongy.
|
|
SNAP BEANS
|
Snap beans are best when the pods are firm and snap readily, but before
the seeds within the pod develop. The tips should be pliable.
|
|
BEETS
|
Harvest beets when they are 1-1/4 to 2 inches in diameter. The beet
tops can also be eaten as greens. The leaves should be 4 to 6 inches long.
|
|
BROCCOLI
|
Cut broccoli when the buds are compact but before they turn yellow or
open into flowers. Leave 5 to 6 inches of stem attached. Side shoots that
develop in the axils of the leaves can also be used.
|
|
BRUSSELS
SPROUTS
|
The small sprouts may be picked or cut when they are firm and about 1
inch in diameter. Pick the lower sprouts as soon as they are large enough
for use. Lower leaves may be removed to allow more room for sprouts to
develop.
|
|
CABBAGE
|
Cut the heads when they are solid, but before they crack or split. In
addition to harvesting the mature heads, you can harvest a later crop of
small heads or sprouts that develop on the stumps of the cut stems. The
sprouts will be 2 to 4 inches in diameter and should be picked when they
are firm.
|
|
CARROTS
|
Carrots are ready for use when they are young, crisp, and 1/2 to 1 inch
in diameter. The sugar content is higher in mature carrots, but the
younger ones are more tender. Carrots planted in the summer may be left in
the ground until a killing frost. A straw mulch can be placed over the row
so that the carrots can be harvested until the ground freezes solid.
|
|
CAULIFLOWER
|
Harvest before the heads become overmature and "ricey." The
heads should be compact, firm, and white. To keep the head white, tie the
outer leaves together over the center of the plant when the head begins to
form. Cauliflower will grow 6 to 8 inches in diameter and is ready for
harvest 7 to 12 days after blanching.
|
|
CHARD
|
Use the leaves as they become 8 to 10 inches long while they are still
young and tender. New leaves will continue to grow from the center of the
plant.
|
|
CHINESE
CABBAGE
|
Cut the entire plant at the ground line when the heads are compact and
firm. Harvest before the seedstalks form in the early summer, and before
freezing temperatures in the fall.
|
|
CORN
|
Pick corn when the silk turns dark and starts to shrivel. The kernels
should be bright, plump, and milky. This stage occurs about 20 days after
the appearance of the first silk strands. To harvest, snap off the ears by
hand with a quick, firm, downward push; then twist and pull. Corn is at
its prime eating quality for only 72 hours before becoming overmature.
|
|
CUCUMBERS
|
Cucumbers may be picked when they are 2 inches long or less for
pickles, 4 to 6 inches for dills, and 6 to 8 inches for slicing varieties.
A cucumber is at its highest quality when it is uniformly dark green,
firm, and crisp. Cucumbers are past their prime if they are large, dull,
puffy, and yellow. Remove old fruits from the vine so that young fruits
will develop.
|
|
EGGPLANT
|
Harvest eggplant when the fruits are 6 to 8 inches long, glossy, and
have a uniformly deep color. The fruits are overmature when they become
dull, soft, and seedy. Use a knife or pruning shears to cut the fruit off
the plant. Leave the green calyx attached to the fruit.
|
|
ENDIVE OR
ESCAROLE
|
Cut the plants at the ground level when they are fully developed (10 to
12 inches across) and the center leaves have been blanched.
|
|
GARLIC
|
Pull up the bulbs when the tops start to yellow and dry. Place the
bulbs on screens to dry. When dry, trim the roots out close to the bulb,
remove the loose outer sheaths, and store under cool, dry conditions.
|
| GREEN
BEANS
|
Beans are a warm weather crop, and can not tolerate any frost nor cold soil. In the U.S.
green beans typically peak during July through October
in the South, and in August and September in the North. But they can be
ready as early as early June in many places, as they only take 45 to 60 days
from the time the seed is planted! For more

HORSERADISH
|
Dig the roots anytime from late fall after a hard freeze until growth
starts in the spring.
|
|
JERUSALEM
ARTICHOKES
|
Dig the tubers anytime from September until
after a frost, and in the spring before the new growth starts. |
| KALE |
Break off the outer leaves as they become 8 to
10 inches long. New leaves will continue to grow from the center of each
plant. |
| KOHLRABI |
The best time to harvest is when the bulbous
part is 2 to 3 inches in diameter (size of a golf ball). Large, older
kohlrabi is tough and woody and may have an off flavor. The young leaves
can be cooked like spinach. |
| LEEK |
Harvest in late summer and fall by loosening
the soil with a spading fork and pulling out the plant. Cut off the roots
and all but 2 inches of the green leaves. |
| LETTUCE |
Leaf lettuce reaches maximum size in 50 to 60
days. Cut or pull the outer leaves (4 to 6 inches long) as you can use
them. Butterhead varieties form small, loose heads that are ready in 60 to
70 days. |
| MUSKMELONS |
They develop their best flavor when they ripen
in warm, dry weather. As the melon ripens, the stem separates readily from
the fruit. After harvesting, the fruit can be held at room temperature for
1 to 3 days until the blossom end softens. |
| MUSTARD |
Harvest the leaves when they are young and
tender, about 6 to 8 inches long. In the summer, the leaves become tough
and develop a strong flavor. |
| OKRA |
The okra pods should be harvested while they
are immature and still tender (2 to 3 inches long). The large pods become
tough and woody. The pods must be picked at least every other day if you
want the plants to remain productive. |
| ONIONS |
Green onions may be harvested when the tops are
6 inches high and the stem is the thickness of a pencil. Harvest dry
onions in late July or early August after most of the tops have fallen
down. Allow the bulbs to air dry for a day or two after digging. Then they
can be stored in a dry shelter on slats or screens, or hung in small
bunches. Complete drying or curing takes 2 to 3 weeks. After curing, the
tops should be cut 1-1/2 to 2 inches long. Place the bulbs in dry storage
with good air circulation. |
| PARSNIPS |
Parsnips should be left in the ground until the
tops freeze, since they are not fully flavored until after early frosts.
The moderate sizes are best. Larger ones may be woody. If you do not have
storage facilities, you can leave the roots in the ground and mulch them
with straw so they can be dug up throughout the winter. |
| PEAS |
Pick them when the pod is full and green and
the peas are still tender and sweet. Test for maturity frequently by
picking a couple of pods and examining them for firmness. Harvest the
Chinese and snow peas, which are eaten pod and all, when the pods are
1-1/2 to 2 inches long and the peas are about the size of BB's. The pods
are usually picked 5 to 7 days after flowering. |
| PEANUTS |
Harvest in early to mid-October, before a hard
freeze. The plants turn yellow when they are mature. Dig up the entire
plant and shake the soil off the peanuts. Cure them by stacking the plants
in an open shelter or by hanging them in a warm, dry shed or garage for a
week. After the plants have dried, shake off any remaining soil and pull
the peanuts from the vine. Continue to air dry for another week or two.
When the peanuts are dry, they are ready to shell or roast. |
|
PEPPERS
|
Fruits may be harvested at any size, but they are
usually picked when they are full-grown and mature. They may be left on
the plant to ripen fully to a red or yellow color, when they will be
mellower and sweeter. Hot peppers, except Jalapeño (which remains green
when ripe), are usually harvested at the red ripe stage.
|
| POTATOES |
"New" potatoes can be dug before the
vines die. For large potatoes, wait until the vines die. Use a spading
fork. Dig 4 to 6 inches beneath the soil surface. Handle the tubers gently
during harvest to avoid bruising. |
| PUMPKINS |
Allow them to ripen fully on the vine, but pick
them before the first heavy freeze. The fruit should have a deep-solid
color and a hard rind. Cut pumpkins from the vine, leaving 3 to 4 inches
of the stem attached. Pumpkins without stems do not store well. Store in a
cool, dry area (50° to 55°F.). |
| RADISHES |
For the best flavor, start thinning and eating
radishes when they are the size of marbles. They will be good up to 1 inch
in diameter. After that, they may become hot and pithy. |
| RHUBARB |
Do not harvest the first year. Harvest only for
1 to 2 weeks the second year. Thereafter, stalks may be harvested for 8 to
10 weeks. To harvest, pull the leafstalks from the plant. Only the stem
(petiole) is used, since the leaves contain large amounts of oxalic acid
and should not be eaten. |
| SPINACH |
Spinach may be harvested from the time the
plants have 6 to 8 leaves until the seed stalk develops. For the best
quality, cut while young. Cut the entire plant off at the soil surface. |
| SQUASH |
Summer squash should be harvested while still
young and tender - 6 to 8 inches in length and 1-1/2 to 2 inches in
diameter. Scallop squash are best while small, 3 to 4 inches in diameter
and a grayish or greenish-white in color. Squash grow rapidly and are
usually ready to pick 4 to 8 days after flowering. Harvest winter squash
when the vines have died back and the fruit has a hard ring, but before a
heavy frost. Cut squash from the vines carefully, leaving 2 inches of stem
attached. Avoid cuts and bruises. Store in a dry location at 50° to 55°F. |
SWEET
POTATOES |
Harvest in the fall before frost kills the
vine. Handle carefully when digging to avoid bruises. After digging, let
the roots lie exposed for 2 or 3 hours to dry thoroughly, then put them in
a warm room at 85°F. to cure for about 10 days. Store at 50° to 55°F
and 85 percent humidity. |
| TOMATOES |
During hot summer weather, pick the tomatoes
when they have a healthy pink color and let them ripen indoors. Tomatoes
do not need to be in the sunlight in order to ripen. If you have green fruit on
the plants in the fall when frost is approaching, pick the tomatoes and
store them in a cool, dark place to ripen. |
| TURNIPS |
Harvest when the roots are 2 to 3 inches in
diameter. The tops can be used for greens when they are 4 to 6 inches
long. Turnips can be left in the ground after a heavy freeze and mulched
with straw for harvest during the early winter. |
| WATERMELONS |
Use a combination of the following indicators
to determine when watermelons are ripe; (1) light-green, and when the
curled tendril near the stem begins to shrivel and dry up; (2) the surface
color of the fruit turns dull; (3) the skin is rough and resists
penetration by a thumbnail; and (4) the bottom of a melon where it touches
the ground turns from a light green to a yellowish color. Watermelons will
not continue to ripen after harvest. |
