How to Grow Truffles at Home

Originally grown in France and Italy, truffles have quickly become a symbol for fine dining. However, they are notoriously tricky to grow, which is why they afford quite the price on the market.

Still, we now see many other truffle orchards sprouting across China, Northern Africa and the Pacific Midwest. 

What Are Truffles? 

How to grow truffles in your garden

Truffles grow as part of an underground fungus, around individual trees' roots, like oak, fir or hazelnut trees. The truffle is the fruiting body of the ascomycete fungus and looks quite a bit like a mushroom. 

Although not a mushroom, it is many times put into the same category. Truffles fall either into the white or black variety, with the black truffle offering far more flavor and coming in as more expensive. 

Truffles are primarily considered a culinary delicacy and provide an earthy, rich, mushroom-like flavor to food. 

Can I Grow Truffles at Home? 

It is absolutely possible to grow truffles at home; however, it will not be without a challenge. You will need to make sure that you choose the right kind of tree and provide the truffle fungus with the exact right growing conditions. 

Even so, it will be a few years before you'll be able to harvest your truffles, so proper patience is vital.

How to Grow Truffles

Once you've established the right conditions, and chosen the right truffle-friendly tree, the ascomycete fungus can be left alone to do what it needs to do.

That's why it's essential to set up your ideal growth conditions before buying a tree. The right soil condition is important to how do truffles grow, so, that's always the best place to start.

You'll want to ensure your soil is: 

  • Well aerated
  • Has a high PH level between 7.5 and 8.3. 
  • Is Lime Rich/ Fed with Lime.

For optimal truffle growth, a substantial amount of sun will also be required, so be sure to plant your tree in a spot that gets plenty of direct sunlight.

How to Choose the Right Tree

You'll need to ensure you buy a host tree from a trusted supplier as the host tree roots must be inoculated with truffle fungus spores. Otherwise, you won't see any truffles growing. 

Oak tree inoculated with truffle fungus spores

There are a few trees to choose; however, the most recommended are varieties of oak trees. 

Popular truffle-host trees include: 

  • English/White/French Oak Trees

  • Beech Trees
  • Fir Trees
  • Poplar
  • Hazelnut

Again, the host-tree roots must be exposed to spores of the truffle fungus.

Planting Your Host Tree

It's essential to take extreme care when planting your host tree and supplement the soil with plenty of lime to support the fungal growth. 

When choosing your spot, ensure there are no other trees planted within a 30-inch radius, as this will affect truffle growth. 

To plant, simply: 

  • Dig a hole twice the size of the root ball of the host tree. 

  • Use a spade to loosen the base soil and feed with a lime soil amendment.
  • Place the rootstock into the hole, backfill with soil and then compact well around the tree's base.

How to Take Care of Your Host-Tree & Truffles

Truffles are a massive trend in the culinary industry

Once planted, you won't need to add care other than general garden maintenance and care for your host tree. This will include regular watering, weeding and feeding with lime. 

Watering

As with most plants, water-logged soil is not what you want. Occasional watering is best, and it is recommended to try to use as much rainwater as possible, as this helps to fill the soil with all the right nutrients. Always check to ensure that your soil is draining effectively. 

Weeding

It's imperative to keep the base of your tree weed-free. So, be sure to de-weed regularly. However, take extreme care that if you are using gardening tools, like a hoe, never go too deep as this can affect the area where your truffles will be growing. 

Feeding

You won't need to supplement your plant with any particular plant food. However, Truffles need lime-rich soil, so be conscious to boost your soil with some lime or limestone regularly. 

How to Harvest Truffles

It is vital to note that even with the very best care and conditions, you will only start to see results after three years and your truffles will take a solid 5 to 10 years before you'll be able to harvest a decent-sized crop. 

Once the truffles start growing, they'll begin to kill off any grass or plants around the base of your tree. So, if you begin to notice a lack of or die-off vegetation around the tree, you'll at least know that they're there and can slowly start planning when you can harvest. 

When it comes to harvesting, this should be carried out in early winter, when conditions are cold, but the ground has not frozen. 

Usually, pigs or dogs are trained to sniff out exactly where the truffles are. However, if you don't have access to a truffle-trained pet, it's easiest just to start, gently, digging around the base of your host tree to see what you find.

How to Store Your Truffles

Truffles don't have a long shelf-life, especially if kept fresh, which is why it's advisable to consume your fresh truffles within the first 5 to 7 days. 

You'll want to clean your truffle harvest of any soil, and then store them in an air-tight plastic or glass container. Keep this container in the fridge. 

Try to avoid allowing too much moisture in the container. Should you notice a white mold forming, simply wipe off with a kitchen cloth. This mold is entirely harmless and simply caused by too much moisture. 

Alternatively, you can consider slicing and storing your truffles in a freezer which will allow you to keep them for 1 to 2 months at a time. 

The most popular method of preserving truffles, especially for Italian homemakers, is to make a Truffle oil. To make truffle oil only: 

  • Slice your truffles thinly and add them to a glass jar. 
  • Fill the jar with olive or sunflower oil.
  • Allow the oil to infuse with the truffles. 

This way you can preserve your truffles for months, and you can add a flavor-filled oil to all your cooking.

Potential Pest & Disease Problems

Being a fungus themselves and growing underground, your truffles won't have any problems. Plus, any issues wouldn't be visible to you either. 

What is essential is to maintain the health of your host tree. Keep up with general tree maintenance and pruning, and check for any diseases specific to your chosen host tree. 

Your tree may attract the odd slug, snail or collembolans, which will affect truffle growth. However, you can use everyday coffee grounds to keep them at bay.

Wrapping Up How to Grow Truffles at Home

As long as you feed your soil with lots of lime, water occasionally and keep your host tree happy you'll be able to enjoy your truffles in a few years. 

Just remind yourself to stay patient and keep checking for signs that your truffles might be growing. Of course, you won't see much of that until three years after planting. Just trust the process. 

When growing truffles at home, the fruits of your labor really will be worth it in the end! So, there you have it. Everything you'll need to know on how to grow truffles at home.
