Awesome Alliums: Tips for Onions, Garlic, Leeks

Alliums are tasty, versatile crops, including leeks, bulb onions, shallots, perennial onions, bunching onions, ramps, and garlic, that are key ingredients in a wide range of cuisines and recipes. While they aren’t difficult to grow, getting good production can be tricky. Here are a few good tips for onions, garlic, and leeks. 

Choose the Correct Variety for Your Area

Alliums can be a bit fickle about where they grow. Onions require certain lengths of daylight to bulb up properly, garlic needs specific temperatures, and leeks can require a long growing period. Choosing a Variety appropriate to your area is the only way you’ll have success.

Bulb Onions

We carry long-day (LD) and short-day (SD) type onions at SESE. You may also see intermediate-day or day-neutral onions available at other places. 

Long-day types begin to form bulbs when the day length is between 14 and 16 hours. Plant long-day type onions in the spring from Virginia northward. Note that not all long-day types can bulb up as far South as Virginia, but ours can.

Short-day types begin to form bulbs when the day length is between 10 and 12 hours. Short-day types can be spring or fall-planted in Virginia and fall-planted in the South. If started in a greenhouse or in the fall and kept refrigerated as sets, short-day onions can be grown in small bulbs in the North.

Intermediate-day or day-neutral onions are ideal for gardeners that live right on the edge, usually in zones 5 and 6. They aren’t daylight dependent and will produce well in almost any area.

Looking at day length isn’t necessary for bunching or perennial onions.

Garlic Drying in the Barn after Harvest

Garlic

At SESE, we carry four types of garlic; hardneck, softneck, Asiatic & turban, and elephant garlic.

Hardneck or rocambole garlic is better adapted to cooler climates and performs best from Virginia northward. It has become more popular recently because it produces flower stalks or scapes that can be cut and eaten before the garlic is ready to harvest. Hardneck garlic varieties have a diverse range of flavors.

On the other hand, softneck garlic does best in warmer climates and is more domesticated than hardneck garlic. It doesn’t produce scapes. However, the lack of scapes makes it easy to braid softneck garlic. It also stores incredibly well and typically has higher yields. 

Asiatic and Asiatic Turban garlic are tentatively identified as an artichoke subtype. Unlike most artichoke types, the stems are hardneck; however, in warm climates, they may revert to softneck. 

Though elephant garlic isn’t true garlic, it is cultivated in the same way. It has a milder flavor than other garlic, making it perfect for raw use. It’s also excellent steamed with other vegetables. 

Leeks

Leeks aren’t divided into specific categories like onions and garlic. They’re very similar to growing onions and, in some ways, are a bit easier. However, you want to consider each variety’s days to maturity, your climate or growing zone, and when you want to plant them. Leeks may vary widely in days to maturity from the 130 of American Flag (Broad London) Leeks to the 75 days of King Richard Leeks.

Water Management

Alliums don’t like soggy feet but produce better when kept consistently watered. Especially for large bulb onion varieties, regularly watering or using a drip irrigation system on a timer can significantly improve your yields.

Weed Pressure

Alliums do not tolerate weed pressure well. Onions, leeks, garlic, and other alliums can easily be overwhelmed by heavy weed growth and fail to produce well. We recommend spacing allium rows so you can easily weed between them with a stirrup hoe, wheel hoe, or similar tool while the weeds are still small.

Alliums growing in spring garden with hay mulch

Mulch

We recommend using a good layer of mulch for all allium crops as it helps with the above issues. Mulch will help keep the soil cool and moist and suppress weeds. If you have a wet season, you may want to pull the mulch back a week or two before harvesting garlic and onions to allow the bulbs and soil to dry a bit for harvest.

Invest in a Sturdy Garden Fork

It can be tempting to pull alliums from the soil by their tops without digging them. While this may work perfectly fine if you have nice fluffy soil, loosening the soil with a garden fork can be helpful for other gardeners. Trying to pull alliums without the help of a fork can break the stems, cause damage, and may lead to a shorter storage period. 

Alliums are valuable crops in the garden and kitchen but can be tricky to grow. Follow these tips for onions, leeks, and garlic for a productive year.

A Brief History of Garlic

Turkish Red Hardneck Garlic

Garlic’s easy cultivation and powerful flavor has made it a favorite for farmers and chefs alike. It’s is an unbelievably common ingredient in food today worldwide but few people realize that garlic is one of the oldest known horticultural crops. Evidence from historical records suggests that garlic has been cultivated for at least 5000 years! There are references to its use found from ancient Egypt, India, and China.

Garlic is believed to be originally native to Central Asia as this is where it can currently be found growing wild. Many plants referred to as “wild garlic” worldwide are members of the Allium family (leeks, onions, shallots, chives) but are not in fact true garlic or Allium Sativum. All cultivated garlic comes from two subspecies A. sativum var. ophioscorodon and A. sativum var. sativum. Like many “wild garlics” elephant garlic, though tasty, is not a a “true garlic” but is instead a member of the onion genus.

Garlic Scapes

A. sativum var. ophioscorodon often referred to simply as ophioscorodon are the hardneck garlics. They are generally grown in cooler northern climates and typically produce fewer but larger cloves. They also produce garlic scapes or flower heads. These are generally cut off before they open and eaten. This allows the garlic to put energy into the bulb rather than flowering.

A. sativum var. sativum are the softenck garlics. They do better in hotter climates farther south than hardneck garlics do. They’re also favored for braiding and their ability to keep extremely well in storage.

The cultivation of garlic probably came about because it was easy for people to pull up and travel with for later use or to plant somewhere else. Garlic cultivation may have also been a quickly taken up by humans because of it’s ability to reproduce both sexually and asexually. Meaning that garlic can make seed, combining genes with other garlic plants, but it is also very simple to grow garlic clones from individual cloves.

Another reason garlic may have quickly become so popular and widespread is because it grows well in a wide range of climates and soil conditions. Garlic is also very hardy and susceptible to few diseases and pests. So much so that in modern gardens it’s used as a companion plant to deter certain pests.

As people traveled and traded garlic’s use and cultivation spread. Little is known about most of its first travels around Asia but it is documented that garlic was first brought to Europe by the Crusaders.

Interestingly garlic has played more than a culinary role in human history. It’s been used for both spiritual and medicinal purposes through the years. In fact, it’s the most widely recognized medicinal herb.

In medieval times it was believed that garlic could ward off all types of evil. A belief that easily lent garlic for use in warding off vampires. Many cultures also believed that garlic was an aphrodisiac or held special powers relating to love. In the Middle Ages it was grown by the monasteries for its healing powers.

In ancient Greece garlic was given to athletes as it was believed to enhance their power and in ancient Egypt it was often fed to commoners and slaves to keep them healthy and working well. This belief also led to it’s use in feeding both Greek and Egyptian warriors as well as Roman soldiers and sailors who needed to be strong.

Garlic’s use as an herbal remedy is as varied as it is widespread. In ancient China garlic was prescribed for respiratory ailments, digestive issues, diarrhea, and parasites. It was also used in combination with other herbs to treat fatigue, impotency, headaches, and insomnia. It was used similarly in ancient India plus was prescribed to fight infections.

Today garlic is most renowned for its pungent flavor but has also gained some scientific credibility as a medicinal herb. Though there isn’t conclusive evidence some studies suggest that garlic can reduce blood pressure and cholesterol, boost your immune system, and help the body fight off illness and infection through its anti-inflammatory and antibacterial properties.

Garlic’s story is ultimately a human story. This one plant has been handed down, shaping people’s meals (and possibly health) for 5000 years. If there’s an easy to grow plant that deserves a place in the home garden surely it’s garlic.

Remember garlic is planted in the fall so the time to start yours is now!
