Preparing to Plant

Choosing the Right Soil Type

While these plants can grow in almost any soil type, they prefer well-drained, slightly acidic soil. It is best to add a lot of organic matter in areas with clay soils to improve drainage.

Soil pH is also essential when growing Jerusalem artichoke plants. The ideal pH range is between 5.5 and 7, so if your soil is too acidic, you may need to add some lime to raise the pH.

When choosing suitable soil for your Jerusalem artichokes, look for soil high in organic matter. Compost and aged manure are significant amendments to improve soil structure and provide nutrients. You can also add an organic mulch as a top dressing to help retain moisture and keep weeds at bay.


Preparing the Planting Site

No matter how inspired you are to grow your own Jerusalem artichoke plant, properly preparing the planting site is the first step to success. With this crucial preparation, your plants will fare well and likely produce the high yields of fresh artichoke roots you’re hoping for. You need to know about getting your planting site ready for Jerusalem artichokes.

Start by choosing a spot in your garden with at least six hours of direct sunlight daily. Jerusalem artichoke plants need plenty of bright light to thrive. Pick an area that receives full sun for most of the day. These plants are also quite deep-rooted, so look for a spot with at least 12 inches of topsoil.

Next, you’ll need to till the soil. Jerusalem artichokes do best in loose, well-drained soil. After digging a few inches to loosen it up, add organic matter like compost, mulch, and aged manure. These items will help the plants establish a deep and healthy root system.

Once the soil is prepped, you can go ahead and add fertilizer. For best results, work in a balanced 10-10-10 NPK fertilizer before planting. Take care not to fertilize over, as this could lead to too-rapid growth and weak stems.

How to Plant the Tubers

Step 1: You will first need to purchase the tubers. You can find these at your local garden center or order them online. Be sure to select a suitable variety for your location.

Step 2: You will need to prepare the tubers before planting. Start by soaking the tubers in warm water overnight. This will help soften them and make them easier to plant. Once they have soaked, gently scrub any dirt off the tubers and cut off any damaged or shriveled parts.

Step 3: Once your tubers are prepared, you can begin planting! Start by selecting a sunny spot in your garden. Jerusalem Artichoke Plants need a lot of sun to thrive, so ensure your spot is well-exposed. Then dig a hole about 8-12 inches deep and wide. Place your tuber in the hole with the pointed side up. You can then cover it with soil and lightly pat it down.

Step 4: Water your plant regularly. Ensure to water your plant enough to stay moist but not so much that it becomes waterlogged. It is also essential to keep the soil around the plant weed-free, as the plants can become smothered if the weeds grow too much.

Step 5: Wait for your Jerusalem Artichoke Plant to start growing. Depending on the climate and the type of tuber you planted, it could take anywhere from a few weeks to several months to sprout. Once the plant is established, you can begin harvesting your Jerusalem Artichoke!

Caring for Your Jerusalem Artichoke Plant

Once your Jerusalem artichoke plant is established, some essential factors must be kept in mind to ensure its continued health and growth.


Jerusalem artichokes are very drought tolerant. As a result, you won’t need to water them too often or heavily. It would be best if you aimed to water your Jerusalem artichoke plants about every two weeks, but remember to check the soil regularly to ensure it isn’t too dry.

If you’ve had a dry spell, you should increase how often you water your plant, but be careful not to over-water it. Too much water can cause root rot, which will kill your plant. Generally speaking, you should water your plant just enough to keep the soil lightly moist. This means you may have to water less frequently in wetter climates.

You should also pay attention to the weather. Hot, dry weather may require more frequent watering, while cooler temperatures can mean you need to water less often. When watering your Jerusalem artichoke plants, you should use a spray bottle or a watering can to avoid over-watering the plant.


Fertilizing your Jerusalem artichoke plants must be done regularly throughout the growing season. Applying a balanced fertilizer mix at the start of the season and then again halfway through the season is recommended. This will provide the Jerusalem artichoke plants with a steady supply of the nutrients they need to thrive.

When fertilizing, it is essential to use a product specifically designed for Jerusalem artichoke plants. These fertilizers are formulated to provide the right balance of nutrients to plants. Be sure to follow the directions on the fertilizer label and apply the fertilizer to the soil at the base of the Jerusalem artichoke plant. This will ensure the roots can get the full benefit of the fertilizer.

It’s important to remember that you should not go fertilizer your Jerusalem artichoke plants. Too much fertilizer can burn the roots and leaves of the plants, causing them to become stressed and unable to produce a good crop.

Weeding and Pruning

Remove any weeds that are growing close to your Jerusalem Artichoke plant. This helps it grow without interference. Also, remove debris, like dead leaves or sticks that have fallen onto the ground. This helps prevent pests and diseases from coming into the garden.

When it comes to pruning, it’s essential to prune your Jerusalem Artichoke often. This helps the plant stay healthy and strong. The best time to prune your Jerusalem Artichoke is spring or early summer. To prune, trim away any leaves or stems that are damaged or diseased. Feel free to prune vigorously, as it will help promote new growth.

A simple guideline for pruning is to leave about one-third of the stems each year for new growth. This helps to balance out the overall shape and size of the Jerusalem Artichoke. If you prune your Jerusalem Artichoke plants correctly, it can lead to more vigorous plants and disease.

When and How to Harvest

Harvesting your Jerusalem artichoke plant is the last step in growing your garden of these delicious tubers. Most Jerusalem artichoke plants reach their full height of 3-6 feet by late fall, which is time to begin harvesting. Knowing when and how to harvest your Jerusalem artichoke plants is critical for a successful crop.

When is the Best Time to Harvest Jerusalem Artichoke?

The best time to harvest Jerusalem artichoke is late October or early November. The Jerusalem artichoke plant should be harvested after the ground has frozen at least once, as this helps to make the tubers easier to harvest.

How to Harvest Jerusalem Artichoke

When it is time to harvest the Jerusalem artichoke, you can begin by loosening up the soil around the plant with a shovel or spade. Be careful not to dig too deep, as this could damage the tubers. Next, carefully pull apart the many roots and stalks of the Jerusalem artichoke plant to reveal the tubers. Collect the tubers and store them in a dry, dark place.

Storing Jerusalem Artichokes

Ensure that your Jerusalem artichoke plant is well-ventilated to prevent mold and rot from developing over time. The best way to do this is to provide some ventilated container or box to store it in. This could be as simple as a wooden box or as intricate as a plastic container with holes cut in the sides. The container should also have a lid to prevent pests and other critters.

The ideal spot is somewhere that is cool, dry, and dark. Try to find a spot in your home, such as a cellar, basement or garage, or attic, that is not subject to extreme changes in temperature. You may even use a garden shed if you have one. Just make sure there is enough ventilation to prevent mold and rot.

When storing Jerusalem artichoke tubers, the rule of thumb is to ensure there is enough room for them to spread out. You can use a basket, tray, or box as long as it is large enough for the tubers to be spread out in a single layer. Make sure you layer the tubers between layers of newspaper and keep them away from direct sunlight.

Remember that Jerusalem artichoke tubers can be stored in a cool and dry place over the winter. In these cases, it is best to layer the tubers between layers of newspaper and store them in a cool and dry place, such as a root cellar. Just check them for moisture levels every few weeks and rotate them now and then.
