GROWING GREAT GREENS

Dennis Morgeson Agent For Horticulture Washington County Kentucky

GARDENING BASICS

• Select a sunny spot-8 hours daily

• Relatively level

• Well drained

• Water nearby

• Avoid tree roots if possible

PLANNING

• Smaller is usually better

• Test soil and fertilize accordingly

• Organic matter is the fastest way to improve structure

PLANNING CONTINUED

• Plant in proper season, id-128

• Select disease resistant cultivars

• Consult family members for input

WHY GROW YOUR OWN?

• Safety

• Taste/Freshness

• Price

• Nutrition: Darker leaves are more nutritious but greens in general are vitamin powerhouses!

THE GREENS

• Most can be started early without special techniques

• March 1st starts the natural planting season, however?

• Greens are basically any crop we grow to eat the leaves and or stems

• Salad Greens vs Greens

COMMON SALAD GREENS

• http://www.epicurious.com/articlesguides/seasonalcooking/farmtotable/visualguidesaladgreens

• These are just the tip of the ice burg…

LETTUCES

• Romaine or Loose Leaf

• Butterhead or softheads (bibbs)

• Crisphead (hardest to grow)

OTHERS

• Chicory, Endive, Arugula, and or corn salad etc. etc.

• Johnny’s, Baker Creek, Seed Savers Exchange….

• Some or many of these can become very bitter if we get much heat or dry weather, eat them young!

• Shade?

GREENS?

• Generally cooked before eaten

• Turnip greens, collards, kale, flower Sprouts, mustards

• Cooked or raw: cabbage, spinach, Chinese cabbage, dandelion, kohlrabi, swiss chard

CULTURE

• Greens are cool season vegetables that do need full sun

• We generally get two good cropping seasons in Kentucky

• Most can be sown directly into the garden in early to mid March

• Raised beds are a good option for greens

PLANTING

• An application of a complete fertilizer such as 4 lbs 10-10-10 per 100 square feet or so should be incorporated into the top 3-4 inches of soil

• Leaf and small head lettuce and turnips sow ¼ inch deep and thin to 4-6 inches apart

• Mustards and spinach plant ½ inch deep and thin to 4-6 inches

• Swiss chard and kale plant ½ inch deep and thin 8-12 inches apart

• Thinning should not be delayed or you will get weak spindly plants with little foliage

• Plant successive crops at 7-10 day intervals for continuous harvest

CULTURE

• Mulch to conserve moisture, keep soil cool, and reduce weeds

• Straw, grass clippings, leaf mold, etc.

• What about plastic?

• A second application of fertilizer banded should be applied when plants are 2-3 inches tall and lightly worked in followed by irrigation

• Kale may benefit from a third application when 8 inches or so tall

• Note: Many of the greens have a better flavor if grown in the fall and harvested after the weather cools

HARVEST

• Loose-leaf lettuces 41-50 days

• Romaine lettuce generally take 70-80 days

• Butter and crisp heading varieties 80-90 days

• Most greens are not harvested fully meaning individual leaves are taken over time so harvest can actually last months or even spring through fall (chard)

• All greens and lettuces should be harvested when fully hydrated early morning or late evening and wrapped in plastic with a few holes and refrigerated quickly

PROBLEMS

• Several fungal pathogens attack lettuce generally in cool damp weather, pull and discard plants to reduce spreading, good sanitation and crop rotation is best

• Plant resistant cultivars if problems have occurred in the past, generally problems are few however in a homeowner situation

PROBLEMS

MICROGREENS

• Microgreens are young, tender, edible crops that are harvested as seedlings.

• Grown to first true leaf stage

• Different from sprouts?

• Labor intensive, but easy!

• Best started indoors in a greenhouse, high tunnel, cold frame etc.

• Use sterile medium, requires very little if any fertilization

• Ready for harvest in 7-14 days

• Highly perishable, generally eaten raw or used as a garnish

• Little time for insect or disease problems to occur

SPROUTS

• Simply germinated seedlings

• Can be eaten raw or cooked

• Most common sprouts are alfalfa, mung bean, soybean, lentil, cabbage, radish, and rye

• Use only seeds labeled for sprouting, many seeds have been treated with insecticides etc and are not edible

• Where to buy? Online, health food stores, produce section of stores etc.

• Why grow your own?

GROWING SPROUTS AT HOME SAFELY

• Hint: You don’t need an actual sprouter, Mason jars are fine!

SPROUT NUTRITION

SEASON EXTENSION-COLD FRAME

SEASON EXTENSION-HOT BED

• 12 to 18 inches of manure under hotbed with 4 to 6 inches of soil on top

• Plant when soil temp drops to 85 degrees

CONSERVING ENERGY

CONSERVING ENERGY

EXTEND THE GROWING SEASON• Hoophouses (High Tunnels) are relatively inexpensive (compared to

greenhouses)

• Greenhouses ($20/sq ft) High Tunnels ($.50/ sq ft)

HIGH TUNNELS• Single layer of plastic

• No heat or cooling (other than venting)

• Irrigation a must

SEASON EXTENSION

Most cool months in Kentucky high tunnels can be used for lettuce and greens production, very little growth however in mid December through January
