Leeks are a member of the onion family, and can be grown in most types of soil but best grows in well-drained sandy loams. Leek plants need consistent moisture to grow properly so make sure your garden beds are at least three inches deep over fertile or clay soils. The leaves should have an even surface without any discoloration or spots on them if they don’t you may want to get some earthworms that eat rotting plant debris from the top layer of the soil

Leeks are a type of onion that can be grown at home. They require little care and will grow well in pots. The best time to plant leeks is from March to May. Leeks should be planted about 15-20cm deep, with the crown just above the soil line. Leeks need plenty of sunlight and water during the summer growing season.

The number of recipes that you may make using leek as a seasoning or as the primary component is endless. Even if you have this list, if you don’t know how to cultivate leeks, you won’t be able to utilize them. That’s something we’d want to change here.

You’ll enjoy growing leeks with this guide, whether you want to put your vegetable-growing talents to the test or have leeks on hand at all times. Have a peek below for all you need to know about the procedure, plus a little extra – take a look!

When Should You Plant Leeks?


To begin with, when should you attempt to grow leeks in the first place? Well, it depends a lot on where you’re attempting to do it.

They’re usually spring plants. That is, if you want them to develop well until the autumn, you must plant them in the spring. However, if you plant them early in the summer, they will still grow if the circumstances are appropriate.

Some varieties of leeks are frost resistant. As a result, they’ll be able to withstand the final week of winter. This is a wonderful option if you want to produce leeks by late April.

In a nutshell, if you reside in a warm climate, grow them in the summer or early autumn. If you reside in a cold climate, however, start in the spring to escape the winter.

How Much Room Do Leeks Require?

Leeks, despite their fairly tiny stem, take up a lot of room. For them to flourish, you’ll need a diameter of at least 6 inches. Otherwise, the leeks may not be able to develop correctly due to a lack of room.

Growing them in big garden beds is usually the best option. If you’re growing in containers or raised beds, ensure sure there’s adequate room around them and that they’re deep enough (at least 10 inches).  

What is the Best Soil for Leeks?

We can confidently state that leeks will grow in practically any soil if the overall circumstances are suitable. However, it is also reasonable to assume that more effective soil for the plants may always be prepared. This comprises soil that has been fertilized, composted, and is well-drained.

It’s also critical to maintain a high level of organic matter. That is why plain compost is often insufficient. To ensure more efficient fertilization of the soil, we propose adding well-rotted compost, preferably something as rotten as possible.

As a result, you may wish to raise the pH of the soil to between 6 and 7, which is somewhat alkaline. You’re more likely to have success with your leeks plants if you can assure a thoroughly manured soil with this pH level.

How to Grow Different Types of Leeks

types of leeks

Now that you know where and how to plant leeks, let’s look at the numerous sorts of leeks plants you’ll come across. We propose the following species:


One of the most popular, with long leaves and a thin stem. It is well-known for its ability to develop quickly. It is usually ready to harvest in August and September if planted in the early spring (about 100 days).

Flag of the United States

Resistant to frost and winter, the Flag of the United States has large and blue leaves. The stem reaches 2 inches in thickness. It tends to fully mature in 110 to 130 days.

Giant of Autumn

This sort of leek is mostly used for display, but because of its size, it may also be a wonderful addition to the kitchen. Some of the leaves may grow to be 30 inches tall, and the stem can be up to 3 1/2 inches thick. It takes roughly 150 days for it to reach full maturity.


The Atlantic leek is one of the most winter-hardy vegetables, and it may be planted anytime from early spring to late autumn. It has green-blue leaves that grow to approximately 10 inches in length. It takes 120 to 140 days to reach full maturity.

Giant from the start

Another fast-growing leek variety, the Giant from the start only takes 90 to 100 days to be ready for harvesting. The stem typically reaches 2 and a half inches of thickness. And its taste is excellent among the fast-growing varieties.


The Hannibal leek is a thick and tall leek that may be planted in the summer or spring and will grow until autumn, when it is ready to harvest. This species may produce growth in as little as 90 days.


The Jolant is one of the thinnest and tiniest varieties of leeks, growing little more than 1.5 inches thick and with a mild flavor. The capacity to flourish in the early autumn and late winter gives it an edge.


Lancelot is the leek that matures the quickest. After just 80 days of development, it might be ready to eat. The leaves may reach a length of 14 inches, and the stems are super-white and mild. It is a species that is very adaptive and resistant.


Tadorna is another famous leek variety. It’s a great option for planting in the autumn and late summer since it can withstand the winter. The length and thickness are ordinary, but the flavor is delicious. It takes 90 to 110 days to complete.

Should I start with seeds or scraps when growing leeks?

You must also decide whether you like seeds or scraps (the bottom portion of the stem) for planting, in addition to the kind of leeks plants you choose for the task. Both solutions have advantages and disadvantages. We go through this in greater detail below:


If you’re beginning from seed, we suggest starting with pots or trays. You may even directly plant them in garden beds, but they’ll need temps above 55 degrees Fahrenheit to grow.

It is advised that seeds be planted just a couple of inches deep. The perforations, however, should be small (1 inch in diameter).

If you’re using seeds, you’ll need to water them several times a day and keep the soil wet. This should be done from the time you plant until the first seedlings emerge from the soil (about 12 days).


You may always remove the roots section of a stalk and plant it if you want to make things simpler. This will result in quicker growth with less maintenance.

We suggest putting the chopped stalk in a cup with water for a few of days to guarantee that it grows healthily. It’s ready to plant when small green leaves begin to grow.

You’ll need to keep it to a depth of no more than 3 inches. Nonetheless, you should water for a few hours every day. In around 8 days, the first seedlings should emerge.

5 Steps to Growing Leeks

Now that you have a better understanding of how to cultivate leeks, it’s time to show you how to do it correctly. In only 5 stages, you’ll discover how to prepare those leeks for ingestion. Take a look at this:

Fertilize the soil first.

First and foremost, ensure sure the soil in which the seeds or trash will be planted is well nourished. While leeks may grow practically anywhere, soil that has been adequately manured is always preferable.

On top of the soil, we suggest putting a lot of nitrogen. Then attempt to blend everything together so that it doesn’t overwhelm the seeds and create difficulties.

It’s best to use less fertilizer and concentrate on well-composed soil if you’re growing in containers or raised beds.

2. Getting the Leeks to Grow

After you’ve prepared the garden soil, you may begin spreading the seeds. If you’re utilizing rooted stalks, the procedure is almost same.

First and foremost, ensure that the location is excellent. Leeks need many hours of direct sunlight every day to flourish.

Then, make sure there’s enough room for the leeks to grow. This usually translates to 6 inches between plants.

You’ll need to water your plants every 8 to 20 days after they’ve been planted (depending on the season and type of leek you planted).

3. Place the leeks in the ground (Optional)

If you begin with seeds in tiny pots, 4 weeks is an ideal time to transfer them into garden beds or big raised gardens.

When the seedlings are approximately 8 inches tall, they are ready to be transplanted. The majority of stems will be roughly 0.5 inches thick.

Take a small trowel and make a hole approximately 2 inches in diameter and 6 inches deep with it. Cover the stem and roots of the seedling and place it inside.

You’ve now established a permanent home for the leek. It should take roughly 6 weeks for it to start developing presently.

4. Fertilize & Mulch

Even though leeks are low-maintenance, you can always optimize the process by adding fertilizer and mulch to the soil.

Every 7 to 14 days, we suggest fertilizing and mulching (1 to 2 weeks). This should aid in the preservation of moisture, the increase of nutrients, and the prevention of illness.

Remember to keep the moisture flowing. Using a soaking hose at this point may be really beneficial. Simply keep the soil damp (but not wet) throughout the day.

5. Harvest & Store

Most varieties of leeks will begin to develop once 100 days have passed. You’ll be able to harvest them for immediate consumption right here.

We propose covering part of the leaves with an additional layer of dirt on the stem. This should be done around two weeks before you attain full maturity. This should result in stems that are somewhat longer and white.

It’s critical to understand that leeks begin to degrade throughout the blossoming period. So, if you want to eat them ripe and fresh, don’t let them thrive.

When the stems are at least 1.5 inches thick, you should pull them out of the soil. 2 inches should be sufficient to remove larger species.

After you’ve removed them, clean them and allow them to dry for a few hours. Then you’ll be able to save them in a new location (preferably the fridge).

You may always chop the leaves till just one or two remain if you want them to stay longer without being refrigerated. Then, in a box, put some of the dirt and sand. Close the box after placing the leeks inside. This should give them an additional 8 weeks of fitness.

Plant Care Instructions for Leeks

how to care for leek plants

While we’ve discussed how to keep leeks growing, we haven’t covered how to properly care for them. We’ll show you how to acquire the biggest and tastiest leeks possible:

Keep the Leaves in Good Shape

Dirt tends to attach to the layers of leeks’ leaves since they are thick and have a lot of folds. Cleaning the leaves may seem pointless, but it helps to avoid illnesses and pests, as well as stunting development. This is particularly beneficial during the first four weeks of development.

Maintain a high level of moisture

Leeks are a low-maintenance vegetable. This occurs because they may collect nutrients from the soil if it is suitably moistened. Leeks will develop deficiently and weakly if the soil is not kept wet.

Defend yourself against pests

Leeks are attacked by a variety of pests. Slugs and caterpillars (moths) are the most prevalent of them. 

You may always employ traps, netting to block access to the leeks, and biological measures to prevent them (pesticides).

Keeping Diseases at Bay

Leeks are also susceptible to diseases such as rust. It gradually exposes the plant to rot, beginning with orange tips and progressing to huge brown spots on the leaves. The spot eventually grows bigger, eventually covering the whole plant and rotting it away.

It’s just about maintaining the plants at the appropriate spacing (6 inches apart), watering them regularly every day, and fertilizing them to keep them growing healthily.

If the plant becomes infected with rust, you may always salvage it by cutting off the afflicted leaves. Stop the spread of the disease by isolating the infected leeks from the others (if feasible) and weeding out the area in between.  

Make certain that the environment is in good working order.

Last but not least, maintain a leek-friendly atmosphere. Despite the fact that they are winter-hardy and can resist light frosts, they flourish best at temperatures around 70 degrees Fahrenheit.

At the same time, they need to be exposed to the sun on a regular basis (4 to 6 hours a day). What’s more important, give them plenty of room to grow without being hampered.

All of these suggestions should help your plants develop faster while avoiding typical difficulties. To get the best results, follow them to the letter.
