How To Plant Garlic In The Fall For Great Harvests Next Year

Learn how to plant garlic in the fall, the best time of year for planting garlic. It then can start growing vigorously once the weather warms up in spring.

Garlic is a versatile member of the onion family. It can be used in so many dishes and is a featured flavouring in many cuisines around the world.

It also has many health benefits, including having antimicrobial properties. I’ve used it to lessen the symptoms of a winter cold.

The downside of course is the smell, but in moderation it’s not so bad.

For the vegetable gardener it also is supposed to help deter some pests. So I try and plant garlic in all of my raised beds, usually on the corners where it won’t be in the way of other crops I’ll grow in the spring and summer.

What Types Of Garlic Are There?

There are two main types of garlic. Both you can plant and grow yourself at home.

Softneck garlic

This type of garlic is the most popular kind sold in supermarkets and grocery stores, as it stores well and thus is easy to ship.

This type is further divided up into artichoke and silver skin varieties and even these varieties have sub-varieties.

It’s characterized by its soft stem that is easily braided.

Hardneck garlic

The other type of garlic is Hardneck and its likely the one you might find at a farmer’s market.

There are three main varieties: Rocambole, Purple Striped Garlic and Porcelain Garlic

It’s characterized by a hard central stem that the cloves form around. And this central stem generates a scape or ramp that will eventually produce bulblets at the end of it.

However these scapes should be cut off once formed so that the energy can go into producing a large head of garlic. The scapes are edible and have a milder garlic taste.

Here’s what they look like.

Elephant garlic – not really a garlic

You might also have eaten this when out for dinner. It’s popular as it has a milder garlic flavour.

However it’s not really a true garlic!

Elephant garlic is actually a type of leek that forms bulbs.

It can be planted just like regular garlic and is similar to a hardneck garlic.

I found the following article that has more info on the types and the cooking applications for each: The Ultimate Garlic Cheat Sheet: Which Type of Garlic Goes Best with What?

When Should You Plant Garlic?

The most common time of year is the fall.

You want to plant the cloves early enough to allow them to generate some roots to secure them in the ground. However wait until the ground temperature has dropped to 15°C (60°F) consistently, otherwise the plant will sprout and can get damaged by frost and freezing temperatures.

You can also plant garlic in late summer, especially if your winter starts early in your area. However usually you will have other crops in, so you might not have space to dig holes and plant cloves. Usually it’s when you pull out summer crops that you then have room to plant garlic.

Definitely plant garlic before your first frost date – it makes digging holes easier. To easily find your first frost date, just type [location] frost dates into Google Search, replacing [location] with your city and province/state/territory (and possibly country). Like this:

victoria, bc frost dates search results on Google

So for me here on the west coast of Canada, I need to plant sometime in October or latest early November. Keep in mind that every year is different, so you do have to play it by ear. Keep an eye on extended weather forecasts.

Then they will lie dormant in the soil all winter until the first days of spring when it warms up. They then burst into growth and send up their thin leaves!

What Diseases And Pests Affect Garlic?

Garlic is an allium, in the onion family, so it’s susceptible to the same disease onions get.

White rot is the most popular and rotating your garlic crops every year and not growing it in the same place is key. Once white rot has set in, your garlic will usually be unusable as the heads will get mushy.

For more info check out this article: Bulletin #2062, White Rot of Garlic and Onions

You can also get rust on your garlic leaves. Usually this doesn’t affect the bulbs unless the leaves get so much rust that they can’t feed the plant. This disease also affects other onion crops such as leeks, scallions (green or spring onions) and regular bulbing onions.

Here’s some more info on allium rust: Leek rust

I cut off the worst leaves when I first see the signs of rust. Again rotating your crops helps to stop the spread of rust.

Garlic has very few pests, mainly because of it’s strong smell and strong taste. It’s often used interspersed in vegetable beds as a deterrent for that reason.

However you may find squirrels digging up the cloves especially right after you planted them.

Sources For Garlic Cloves That You Can Plant

You can buy seed garlic from a nursery, garden centre or online through a seed company. Usually these become available in late summer/early autumn, depending on your climate.

However I have had good results simply buying grocery store organic garlic and splitting up the heads and planting the cloves.

If you decide to go this route, make sure that you buy certified organic garlic. Non-organic garlic may have been sprayed with a sprout inhibitor so that it keeps longer in warmer temperatures.

And of course once you have a decent crop of garlic, save some heads for next year’s planting – in other words, don’t eat it all!

Preparing Garlic Cloves For Planting

It’s simply a matter of splitting up the heads of garlic into individual cloves. I usually peel off the outer skin and then split them up with my fingers.

Try not to damage the cloves otherwise they could be susceptible to disease and rot. Leave the skin on the individual cloves and throw out any that are mushy or are damaged in any way.

This was the result from two cloves. There are over two dozen cloves here.

How Deep Should You Plant Garlic?

Garlic is an exception to the usual rule of planting seeds at the same depth as the seed size. It’s a bulb so it benefits from being planted deeply. Usually 2-3″ (5-7.5cm), but in cold winters, you might want to go a bit deeper.

It makes it harder for critters like squirrels to dig them up and protects them to some extent from frost and light freezes.

Also when the garlic cloves finally sprout they have good support in the ground. Garlic plants don’t produce large roots as other tall plants have to stay upright, such as broccoli or tomatoes.

What Garden Tool Should You Use To Make Holes For Planting Garlic

I use my deep-rooted weeder to make my holes to the 2 or 3″ depth. It can power through compacted soil and helps loosen it.

You can buy a similar weeder on Amazon if you can’t find it locally at a nursery or garden center:

If you are planting in rows you can also use a hoe to dig a deep furrow.

How To Plant The Garlic Cloves

Now that you have the hole ready, it’s time to pop in the cloves.

Before I show you that, a word about fertilizers. Typically garlic doesn’t need extra fertilizer at the time of planting. There really is no point as the clove won’t actively start growing until the spring when the weather warms up.

So you can just drop the cloves into the holes you made. I try and make sure the clove sits upright.

The top of the clove is the pointy part and the bottom is where the roots on the original head of garlic were.

All that is left is to fill in the hole with soil. You can also watch a video of how to do this:

Do You Need To Mulch The Soil Around Your Planted Garlic?

In very cold winters, it does help to mulch over top of the garlic with either leaves, straw or some other mulch. It also will conserve moisture the following spring and summer as the plants grow.

Do I Need To Do Anything Else To Grow Garlic?

Not really. This is a crop that just happily grows without much input from you. Just make sure it gets at least an 1″ (2.5cm) of water a week as is usually the case for most veggies and fruit. Keep in mind though that too much water will rot the garlic.

When And How To Harvest Garlic

Harvest time will depend on the weather. If you have warm, dry weather, your garlic will likely be ready early in the summer, even as early as May or June.

As scapes form and curl around once, I cut them off. Scapes can be used in dishes fresh like you would use green onions, or dried or made into a pesto.

If you can stop watering the garlic for at least a week before digging them out. This may be difficult to do if you have the garlic spread out among your other plants as I do. I don’t worry about this too much.

The way to tell when the garlic heads are ready is when the tops start to brown and die off. Usually the general advice is to wait until about half turn brown.

Don’t wait until all of them die off otherwise you will find the cloves starting to separate and wanting to grow new heads. When that happens they won’t store well.

You can always dig carefully around one plant and check out the top of the head of garlic.

Carefully using a shovel or garden fork, leverage the heads out of the ground. Unless your soil is very loose, you’ll probably not be able to simply pull them out by the stalks.

Brush off as much loose dirt as possible (don’t wash them!) and then hang them up in an airy, warm place to dry out. I usually hang them in my greenhouse that is dry in summertime.

Once dry, store them in a cool, dark place and start using them in your cooking! Periodically check to see if any are rotting and remove them before they can start the others rotting.

Summary Of Garlic Growing Tips

So in summary here are the garlic growing tips:

  1. Plant in corners of existing vegetable beds
  2. Plant in late summer or fall before first frost
  3. Plant 2-3″ deep or more if very cold winters
  4. Plant upright, root side down / tip up
  5. No need to water or fertilize at planting; add mulch if very cold winters
  6. Keep well watered – 1″ (2.5cm) per week
  7. Harvest when half the tops start to brown, dry well before storing
