Presenter:  Alan Wagner, Extension Master GardenerSM Volunteer

Vegetable gardening does not have to end in September.  You can plant a fall garden and extend your growing season with a second harvest into the fall and winter.

Alan Wagner, Chair of The Learning Garden’s vegetable plot located at the Buncombe County Extension office, discusses what cool weather vegetables to plant and when to plant them.  He shares many tips for extending the growing season using cold frames, hoops, and row covers.

Edible Alliums: Chives, Garlic, Onions, and Shallots for Fall Planting

August 5, 2016

Think fall is only a time for harvesting? Meet the Allium family! Plant chives, garlic, bunching onions, and shallots beginning in September and October for eating next year.

You can grow most alliums from seeds or small transplants, but fall is the ideal time for planting allium bulbs—also called sets—and to make divisions of clump-forming alliums from your garden or a friend’s. 

The basics—a sunny spot and fertile soil
Alliums require a sunny garden spot with good drainage. If you haven’t tested your soil in the last three years to adjust soil nutrients and pH—the soil acidity—do it now! Kits for sending your samples in for free testing are available at the Extension Office and Extension Master Gardener Volunteer information tables and plant clinics. 

Bulbs—source varieties best for growing in WNC
It is easy to plant garlic, elephant garlic, bunching onion, and shallot bulbs. These look just like what you’d buy for cooking, but think twice before planting store-bought produce. Bulbs sold in supermarkets are often varieties that grow best in other areas or are treated to delay sprouting.

Buy bulb varieties suited to Western North Carolina from nurseries or seed companies, or from a local farmer. You can ensure you’ve planted varieties you’ll enjoy by sampling bulbs at a local farmer’s market.

Garlic (Allium sativum) comes in softneck and hardneck types. Extension Horticulture Specialist Jeanine Davis notes that the garlic bulbs usually sold in supermarkets are softneck varieties. She recommends California Early, many Italian cultivars, and New York White Neck softneck varieties for North Carolina. Davis cautions that hardneck varieties tend to be trickier to grow, but NC commercial growers do well with German Extra Hardy, Chesnok Red, Music, and Spanish Roja. Elephant garlic is actually a leek (Allium ampeloprasum), but you plant and grow it just like true garlic. Always separate garlic bulbs into cloves before planting.

Bunching onions (Allium cepa var cepa and Allium fistulosum) and shallot bulbs (Allium cepa var. aggregatum) are planted whole. Extension Horticulture Specialist Douglas Sanders recommends Ebenezer, Silverskin, or Yellow Globe Danvers varieties for bunching onions grown from sets. Unlike garlic, you may find your sets grow quickly enough that you can harvest “green” onions later in the fall.

 

Planting
Plant your garlic cloves and bunching onion and shallot sets no more than a couple of inches deep and 3 to 5 inches apart. If you plant in rows, allow at least a foot between rows. Keep well-watered.

Divisions
Although you can grow chives from purchased plants or seeds, these plants benefit from division, so if you have a planting or can get a friend to share, you can increase your harvest next spring by digging and separating a chive clump into two or more plants. There is no need to separate the individual bulblets, just cut back the green tops to a couple of inches, dig, pull apart, and replant in a sunny, well-drained spot with the nutrients and lime recommended in your soil test.

The most common garden chives, (Allium schoenoprasum) have pretty, edible purple flowers in spring. You can tell them from garlic chives (Allium tuberosum) by their flowers—garlic chives have white flowers—as well as the fact that “regular” chives have round, hollow green leaves, while garlic chives have flat, solid leaves. The long life and attractiveness of these flowering alliums makes them suitable for ornamental gardens and might tempt you to look for Allium family members grown exclusively for their flowers. Fall is the time to plant these, too!

Walking onion.

The “Walking” onion (Allium cepa proliferum group) is another Allium family member that benefits from division. In this case, in addition to digging, separating, and replanting individual bulbs, you can break apart the mature seed heads, which are also forming new bulbs! As the pollinated flowers form seeds that swell into bulbs, the tiny new bulbs sprout and the weight begins to bend the flower stalk. These heads will eventually reach the ground. Thus, the onions “walk” into a neighboring section of the garden. You can control where the new onions grow by cutting off the flower stalks once the bulbs begin to form and replanting.

Cold Frames, Row Covers and Cool Season Vegetables

September 15, 2015

As the evenings cool and the chance of frost increases, having vegetables growing in cold frames or under row covers will prolong their productivity. A cold frame is essentially a bottomless box made of wood, brick, or concrete block sides with a removable or hinged top of glass or thick clear plastic sheeting. Some are elaborate while others are made from repurposed materials such as old windows and scrap wood. Row covers sit over a single vegetable row and are made with a hoop frame that is covered with clear polyethylene or spunbonded polyester or polypropylene. Medium weight plastics or polyester work best as anything thinner doesn’t offer frost protection, and anything heavier blocks too much sunlight.

The purpose of both cold frames and row covers is to warm the soil and trap warm air at night. Positioning a cold frame so that it faces south on a hillside will keep the soil warmer in the fall and warm quicker in the spring. Remember that if your land slopes, that cold air settles in the lowest areas on calm nights and can create frost pockets. Cold frames and row covers will also lessen the effect of chilling wind.

The tops of the crops should not touch the top of the cold frame or the plastic of the row cover. If they touch, the frost will damage those areas. Although it might be cold at night, the top of the cold frame and the plastic of the row cover should be removed on warm days; otherwise, your plants will overheat and die. A thermometer inside your frame or cover will help you stay aware of temperature changes.

If starting your vegetables from seed, some fall vegetable seed will not germinate if the soil is too warm and might do better started inside. With spring gardens, the converse is true, the soil is often too cool, and the seeds do better begun inside giving them a head start on the season. Remember to harden the seedlings off when transplanting them outside.

Enjoy this fall vegetable season in the garden and later, in your kitchen.
