Garlic

By Sarah Hashimoto
Community Gardener, Autumn 2001


If you love garlic but haven’t grown it before, don’t wait! It’s not too late to get a great crop growing for next year. Garlic is a staple in our kitchen, and now that I have discovered how truly easy it is to grow, harvest, and store, I can’t imagine my garden without it. It requires very little from you as a gardener, and it gives great results in return. Now, if I could just get it to teach those habits to the cucumbers, I would really be set!

Varieties
There are two types of garlic: hardneck and softneck. Hardneck garlic sends up a hard flower stem around which the cloves grow. This kind of garlic is sometimes called “topsetting garlic,” since the stem produces small bulblets at the tip (these bulblets should be removed so that the plant can focus its energy below). Most garlic connoisseurs will tell you that at least as far as taste is concerned, hardneck varieties are superior to softneck varieties , for they are said to have more complex, interesting flavors. My husband, who claims to be a garlic connoisseur, will attest to this fact; all I can tell you is that the hardneck garlic that we grow is indeed delicious. Hardnecks also have bigger cloves that are easier to peel. Hardnecks must be planted in the fall. The one drawback to hardneck garlic is that it doesn’t keep for very long. Usually, you can count on keeping the bulbs for six months, from mid-summer to January.

Hardneck garlic can be sub-divided into several groups: Rocambole, Porcelain, Creole, Asiatic, and Purple-Stripe. Rocambole, probably the most popular of these sub-groups, grows 6-13 cloves/bulb, is easy to peel, and has a full-bodied flavor. I am fond of the Porcelain group, which has the largest cloves out of any of the hardnecks. Porcelains aren’t super hot, but they are very tasty. They also store quite well.

Softneck garlic is distinguished from hardneck garlic because, as you might suspect, the stems are soft and pliable. This means that you can braid the stems for storage (or combine the garlic with dried peppers to make a fabulous gift!). Softneck garlic has superior storage qualities, and thus it is the type you will most often find in the supermarket. Under the right conditions, softnecks will keep for up to ten months. The flavor of softnecks is usually very mild or very hot, with little in between. Softnecks are easier to grow than hardnecks, though, since they are more adaptable to different climates and soils. In places where the winters are extremely harsh, gardeners can plant softneck varieties in the spring and still get a decent, although not as spectacular, harvest.

Softnecks can be divided into a couple of groups: the Artichoke group and the Silverskin group. Artichokes are the most common. They are easy to grow, have approximately 12-20 cloves/head, and keep very well. They grow well in most climates. Silverskins are the kind of garlic you find most often in the supermarket, because they have exceptional storage abilities. They are very productive and perfect for braiding. I should mention, however, that they prefer a slightly warmer winter than the artichokes, which makes them a bit trickier to grow.

Soil Preparation
You’ve probably already guessed what kind of soil garlic likes best. Rich, fertile soil, lots of organic matter, loose, not clayey. If that’s the kind of soil that you have, good for you! You’ll have to let me know how it goes, because I grow my garlic in crummy soil, solid clay (I suspect that it is fill dirt). I have mixed in compost and leaves to lighten things up a bit, but the clay is so hard that it tends to form clumps that are impervious to lightening. I’m sure that lighter soils are optimal, but if you fertilize well during the growing season, I think you can make due with whatever you have available. The one thing that I have learned about garlic is that it is pretty forgiving.

Planting
While it is possible to plant softneck garlic in the spring, for best results, you have to plant in the fall. In Michigan, we plant 4-6 weeks before the ground freezes, usually anywhere from October through November. This planting schedule allows the garlic to start developing a good root system so that it doesn’t get heaved out of the soil when the ground freezes. Usually, the very cold weather hits before it sprouts too many leaves. I should note, however, that even if your garlic sprouts quite a bit, it is not something to worry about. I have seen garlic planted in warmer micro-cilmates, usually right up against houses, and it does just fine.

When planting your garlic, you’ll want to choose the largest cloves. Small cloves usually grow small bulbs. Push the cloves into the soil root-side down (not the pointy end down!) and about 1-2 inches below the surface. Space the cloves 4-6 inches apart. Finally, cover with soil and mulch lightly with hay, grass clippings, or shredded leaves. Mulching is an important step, since this prevents the cloves from heaving out in the winter. Furthermore, mulching also suppresses weeds and helps to conserve moisture.

Grow!
When spring comes, your garlic will start sending shoots up through the mulch. At this point, you should fertilize the plants by sidedressing with compost. For the absolute best results, you can also use a foliar fertilizer of liquid kelp, seaweed, or fish emulsion.

When the garlic greens are still young and tender, pick a few and taste them. Yum! Garlic greens are absolutely delicious. The flavor, as you might suspect, is garlicky, but it also has more than a hint of onion. Some people eat the greens raw, but I prefer to cook them, since the flavor mellows with cooking. We generally use the greens in stir-fry, but I have also tasted garlic pesto, which was quite nice.

Hardneck varieties will send up a tall flowering stalk, with bulblets at the tip in June. Snip the bulblets off, since you want the plant’s energy to go into making a large bulb, not into making seeds. Don’t throw these bulblets away! They are a tasty addition to stir-frys, and a hint of what’s to come.

Problems
What problem? Garlic is rarely bothered by pests. This is because, as you may already know, garlic itself is very effective at deterring a wide range of pests. Garlic sprays are an indispensable part of the organic gardener’s arsenal. If you have the room, though, you should consider rotating crops and not planting garlic where garlic, onions, leeks, or any other member of the allium family has been planted in the past three years. While garlic is generally free from problems, pests, or diseases alike, crop rotation will ensure that the odd disease doesn’t visit your plants at all.

The Great Harvest
Harvesting your garlic is probably the trickiest part of growing garlic, but, truthfully, it’s not very hard at all. Timing is the main thing. If you harvest too early, the skins won’t have formed around each clove. If you harvest too late, the bulbs may have spread apart in the soil, plus the papery outside will be more prone to tearing (this results in poor storage abilities). After about a third of the plan has browned and died off, dig up a bulb and take a look. If it looks good, you can start the harvest right away. If it still looks immature, you’ll want to wait to harvest, checking the bulbs’ progress every few days.

Before garlic can be stored, it must be cured. The main thing to remember when curing your garlic is that you are drying the bulbs, and thus good air circulation is essential. After digging up or pulling the bulbs, gently brush the soil off. Don’t wash the bulbs—remember, think dry, not wet! Don’t worry about cutting off the stalk or leaves, since bulbs dried with their stalks and stems still attached store better. You can dry your bulbs in a number of ways, tying them in loose bundles and hanging them, putting them on screens or drying racks, even simply putting them in single layers on newspapers (in this case, you’ll have to turn the bulbs every so often). The key to successful curing is keeping the bulbs in a dry location away from direct sunlight.

Garlic can be stored for months at a time, so long as it has good air circulation. We have had good results using netted sacks hung from the basement rafters. If you have softneck garlic, you can also braid the stems and hang them up. As far as the temperature is concerned, 45-55 degrees is perfect. If you must, you may store the bulbs at a slightly higher temperature, but a lower temperature may cause the bulbs to sprout.

Sources
The biggest mistake that people make when growing garlic is trying to use garlic that they have purchased at the supermarket. While this garlic may be fine and tasty for eating, it is not appropriate for planting in the garden. The reason for this is that these cloves have most likely been treated with chemicals to inhibit sprouting.

I should also mention that while the initial investment in purchasing garlic cloves for planting may seem high, this is a one-time cost. At the end of the season, set aside some of the largest cloves for planting, and then you’ll have garlic again for the next year. Unless you decide to try new varieties, you shouldn’t have to buy seed garlic again.

Echinacea

by Miki Ludwick and Lynda Asher
Community Gardener, Fall 1997

Echinacea is a native plant indigenous to the central plans of the United States. This perennial member of the Compositae family grows to a height up to about 5 feet; the flowers resemble those of the black-eyed Susan and range in color from purple to white. This attractive plant is found in ornamental as well as medicinal gardens.

Historically, Echinacea was used by Native Americans and frontiersmen as a remedy for snake bites, poisonous insect bites, and for cleansing and healing wounds. Native Americans also used the juice of Echinacea to cleanse burns and in traditional purification sweats.

Today, Echinacea is still highly regarded as an immune system enhancer, antibiotic, and blood purifier. Research indicates that Echinacea stimulates the production of white blood cells to fight infections. This immune boosting quality results in Echinacea being used to treat minor bacterial and viral infections. Specifically, it is used to remedy general infections, colds, flu, strep throat, staph infections, urinary tract infections, tonsillitis, throat infections, upper respiratory infections, infected wounds, burns, allergies, toothaches, mouth and gum infections, blood and food poisonings, abscesses, bronchitis, and eczema.

Three of the nine species of Echinacea are used for medicinal purposes: E. angustifolia (narrow leafed coneflower), E. purpurea (purple coneflower), and E. pallida (pale coneflower). Each species is composed of different sets of compounds and other components that work to help the body heal itself.

Echinacea contains a number of medicinal constituents; some are water soluble, others are oil soluble. These include essential oil, isobutylalklamines, glycoside, polysaccharide, polyacetylenes, and others. It is believed that the fat-soluble components of Echinacea may be more responsible fro the plant’s immune enhancing activity.

Growing Echinacea is an easy task well worth the effort. Germinate all Echinacea seeds at 70 F. (E. angustifolia seeds require a period of chilling prior to sprouting). Echinacea appreciates full sun, moderate moisture, and an alkaline soil amended with compost, kelp, and rock phosphate.

While all parts of the plant are believed to be beneficial, it is mainly the root that is used for medicinal purposes. The healing properties of the root are most pronounced in the third and fourth year of growth. The roots are harvested in the fall after several hard frosts have caused the plant to die back. Herbal lore further specifies that roots are to be collected in the evening during the waning crescent moon.

There are a variety of ways to prepare herbs for medicinal use. These include but are not limited to: teas, infusions, decoctions, tinctures, and salves. The first three are water-based and extract the water soluble constituents, tinctures are alcohol-based and extract the fat soluble compounds. Water-based preparations must be made at or near the time of use as they do not store well; alcohol-based preparations must be made in advance, as they take 2 to 6 weeks to make, but they can be stored for several years.

Infusions

The most common way to use herbs is as an herbal tea infusion. This medicinal tea is a stronger versions of a regular herbal tea. A common infusion is made by steeping 1 ounce (2 cups) of a dried herb in 1 pint to 1 quart of boiled water for 15 minutes to eight hours depending on the plant part used: seeds steep for 30 minutes, flowers steep for 2 hours, leaves steep for 4 hours, roots and back take 8 hours.

Decoctions

Decoctions are made by simmering herbs in water to extract the healing properties from the coarser parts of the plants like the roots and the stems. The herb is added to the boiled water in the same proportions as for an infusion and simmered for 30 minutes to an hour, or until the liquid has been reduced by half.

Tinctures

Tinctures are alcohol-based, concentrated herbal preparations. Alcohol is an effective solvent for many plant constituents; mixtures of alcohol and water extract most of the medicinal properties of an herb, while a the same time preserving them.

Fresh Herb Tincture

Add 100 proof vodka or the spirit of your choice to the top of the jar. Close the jar tightly.

Label the jar with the ingredients used (name and part of the plant, type of spirit) and the date of the preparation.

Top up the liquid level on day 2.

Keep the tightly closed jar in a warm place; shake twice daily.

Decant the liquid in 2 to 6 weeks.

Dried Herb Tincture

Place 2 ounces dried root in pint jar.

Add 10 fluid ounces 100 proof vodka or the spirit of your choice.

Tightly cap and label the jar.

Top liquid level for 1 week.

Decant the liquid in 2 to 6 weeks.

Echinacea may be used as a tonic, at a maintenance level, at a protective level, or to treat an infection.
