Wet leaves, warm temperatures and high
humidity can predispose plants to this disease, but it
can be combated with proper spacing
(for good air circulation), disinfecting pots, crop rotation and
watering earlier in the day if
overhead watering is necessary (8).
Pests can be combated with beneficial
insects, insecticidal soaps, traps and manual removal (24). citrus packing machine Mark
Langan suggests planting in
well-drained, fertile soil to prevent disease. Using this method, Mark doesn’t citrus packing machine
have a problem with pests and diseases
in the landscape (62). Soil-borne diseases can be prevented
with crop rotation. Drip irrigating or
“watering early in the day” can help prevent diseases that affect
damp leaves (24).
Pruning &
Harvesting
14
There are many options when it comes
to pruning and harvesting lemon balm. Leaves can be harvested
as needed. Susan Belsinger suggests
thinning plants in the summer to improve air circulation. This is
particularly important during hot and
humid weather. To thin plants, simply snap a stem off from the citrus packing machine
base. If plant has 30 stems, about 10
should be removed. The thinned stems can then be hung to dry
(5).
In addition to thinning, Susan cuts
her plants nearly to ground level for the three major harvests in
spring, summer and fall. Susan has
found that she can get new growth even in cool weather after the
plant has bloomed and leaves are
turning yellowish-green (5). In Southern California, Theresa Loe citrus packing machine cuts
her lemon balm plants to the ground in
late fall or early winter but they never become dormant and she
can harvest year-round (67).
Plants may brown around the edges due
to excess heat, cold, dryness or high winds (45). Madalene Hill
and Gwen Barclay trim 1 or 2 inches all
around the plant to remove browning and finds that in just a few
days new growth will appear. For
plants that are very large, try trimming one side one week and the
other side the following week. If the
plant has been subjected to more extreme conditions like hurricane citrus packing machine
winds or drought, they would cut it
back to 4 or 5 inches in late winter or early spring(45).
It’s nearly impossible to
over-prune/over-harvest lemon balm (61). According to Lorraine Keifer, in
midsummer,
a large patch can even be pruned with
a trimmer/edger or a mower set on high. She suggests
watering and fertilizing following
this aggressive pruning if soil is poor or plants look “sparse” (59). Mark
Langan has also noticed that lemon
balm can be mowed to the ground and will rebound, but for Mark a
safe rule is to remove up to half of
the plant’s total height (62).
Be sure to prune flowering stalks
before the plant goes to seed to keep lemon balm from spreading citrus packing machine
(101). Andrew Van Hevelingen also
suggests dividing three-year-old plants and replanting, since lemon
balm plants can “die in the middle and creep outwards
like French tarragon” (101).
Essential oil content is reportedly
highest in the top one-third of the plant (76), and one study that took
place in the Ebro-Delta of Spain found
that harvesting in the morning during August and September
produced the best essential oil content
(1).
Many herb enthusiasts believe flavor
is best prior to flowering (12, 45, 81, 87, 88) but for essential oil citrus packing machine
production, plants are harvested at
flowering (92). If harvesting for essential oil production, Mark Langan
suggests cutting plants to the ground
in spring as the first 5-25% of flowers open. Mark points out that
seed production, not flowering,
affects oil production and leaf flavor (62). According to Susan Belsinger,
if the plant is cut back after flowering, new leaves that
appear will have the flavor of spring growth (5).
The flavor of fresh lemon
balm is superior to dried (5, 45, 62, 87, 88), but depending on the season and
your location, drying
lemon balm leaves can provide access to the herb year round.
Lemon balm can be dried by
hanging in bunches, then stripping off leaves (12, 59, 67). It can also be
dried on trays (45, 104)
and should be dried in a dark place (101, 104) with good air circulation (58,
101). Dry within 2 days or
leaves may turn black (87, 104).
Dried leaves can be stored
for 1 year in glass containers in a dark, dry place (43, 67). They can also citrus packing machine be
stored in the refrigerator
for a few days or in double bagged food storage plastic bags in the freezer for
the short term (45).
Freezing
For fresh flavor, even in
winter, Susan Belsinger prefers freezing chopped lemon balm leaves in
vegetable oil. The lemon
balm and oil combination can be added to baked goods (5). Another option is
to freeze whole or chopped leaves and water
in ice cube trays (62).
Lemon balm is a
surprisingly versatile culinary herb which can be used to flavor many different
types of
dishes, from beverages, to
appetizers, main courses and desserts. It can be added to salads,
sandwiches, soups, stews,
butters, cheeses, fish, stuffings for poultry, pork and veal, egg dishes,
vegetables, fruit cups,
jams, jellies, sauces, marinades, dressings, herb vinegar, wine, punch, cakes,
custards, tarts, sorbets,
ice cream, cookies, crepes, pies and cheesecakes (5, 67, 92).
Lemon balm complements
many fruits, including honeydew, cantaloupe, pineapple, apples and pears
(5). For fruit salads, try
mixing fresh lemon balm with pineapple sage (81). For vinaigrettes or salad
mixes, lemon balm combines
well with parsley or basil. It can also be included in fines herbes mixtures citrus packing machine
with dill, tarragon,
parsley, chervil and chives. In springtime, combine lemon balm with fennel and
thyme
