Tips for Growing Great Garlic
Now is the time to buy garlic for planting - unless you have
some from your own garden saved for that purpose, as I do. You’ll want to get
your garlic planted a month before the ground freezes, so depending on where
you live, you may want to plant some soon. Garlic needs to establish roots now,
and is not generally planted in the spring.
Of all the veggies I plant, garlic is the easiest to grow, and a good harvest is guaranteed if follow my instructions. Please don’t sue me if something goes wrong with yours, but I’ve never had a bad year in the past 25 years or so of growing garlic.

There are two categories of garlic: hard neck and soft neck.
Both will grow in New England, but hard neck is the type grown by most farmers,
and the most cold-hardy. It produces a stiff scape or stem each summer that is
edible. Soft neck garden generally comes from California, and is good in the
kitchen; it is also the type braided and hung from the ceiling in Italian
restaurants as decoration. Hard neck garlic generally has more flavor, and a
wide variety of flavors are possible, depending on the type you grow.

Garlic does best in rich soil that drains well. If you have a heavy clay soil (one that is sticky when wet), you will want to add plenty of compost to your soil. Adding sand will not help, as sand added to heavy clay produces something like concrete that hardens up in dry times.
If you have poor soil, you may want to build a wood-sided raised bed, and add plenty of compost and topsoil that you purchase in bulk or in bags. I find Moo-Doo brand composted cow manure and topsoil are a good soil additives that are sold in bags in many garden centers.
When making a wood-sided bed, do not use treated lumber. Even though most treated lumber is safe to handle and much less toxic than 20 years ago, I don’t want any chemicals leaching into my soil. I use rough-sawn lumber from a local sawmill, preferably hemlock. It generally lasts about 10 years. Eight-inch wide planks are wide enough to make a nice box.
Raised beds are great for garlic
Plain pine boards will work, too, and metal corners are readily
available at garden centers or from catalogs like Gardeners Supply and Lee
Valley Tools. The corners make constructing a garden box easy even for
non-carpenters. All you need is a cordless drill to drive the screws. Carrots
and other root crops do well in garden boxes, so you can alternate them with garlic
in subsequent years if you build 2 or more boxes.
Once the soil is loose and weed-free, I plant. I take my long-handled CobraHead weeder, a nice single-tined weeder, and make furrows in the soil of my raised bed. I keep the furrows about 8 inches apart. I sprinkle some organic bagged fertilizer into each row, and stir it in.

I generally use my own garlic for planting, as it has adapted
to my soil and climate over the years. But if I see big, fat bulbs of garlic at
a farmers market, I sometimes buy some. I don’t recommend buying garlic for
planting at the grocery store as most has been treated to prevent it from
germinating, and so it will last longer.
Where can you get garlic for planting? If there is none at your local farmers market, you can get organic garlic from Johnny’s Selected Seeds in Maine (877-564-6697 or www.johnnyseeds.com). But don’t wait too long – they sell out most years.
I break the garlic bulbs apart, separating the cloves – there are usually 5 to 10 cloves per head. I push the cloves into the loose soil, pointy end up, about 3 inches deep, and 4 inches apart. I cover with soil, and then pat it gently.
Place your garlic in the furrows to space it well before planting.
The last step is key if you want a weed-free garlic bed: put a foot of fluffy mulch hay or straw over the planted garlic. The straw will pack down over the winter and make a nice mulch that will keep most weeds from growing, but the garlic will push through it. It will be ready to harvest next July.

Depending on when you plant, the soil temperature, and when
real cold weather comes, your garlic may send up a few green shoots this fall.
Don’t panic! It won’t hurt your garlic. When cold weather comes, it will go
dormant and do just fine next spring.
I believe that garlic is a healthy and tasty addition to my diet. It may even be medicinal – it has been used that way for centuries. Some believe that if you crush your garlic and then wait 10 minutes before cooking, it will generate cancer-fighting compounds. Who knows? Certainly it can’t hurt.
And this winter if you chew on a clove of garlic before going to the store, you’ll never get a cold – because people will stand back from you if they cough!
