Pholiota adiposa | Certifié biologique par l'USDA

Niveau de compétence pour la méthode : Débutant
Niveau de compétence pour l'espèce : Débutant

Découvrez un goût du Japon dans votre propre jardin avec notre Bloc de démarrage de champignons à planter et à cultiver de châtaignier. Cette souche certifiée biologique par l'USDA produit des champignons veloutés avec des chapeaux mouchetés de petite à moyenne taille qui ressemblent à leur homonyme noisette. Attendez-vous à un croquant délicieux, une riche saveur de noisette et un subtil arôme boisé qui rehausse n'importe quel plat.

Les champignons de châtaignier préfèrent les endroits frais et ombragés et nécessitent une humidité constante pour prospérer, surtout pendant leurs premiers stades de croissance. Lorsqu'ils sont plantés et enterrés à l'extérieur, assurez-vous de maintenir une humidité élevée en paillant avec de la paille ou des feuilles mortes et en arrosant régulièrement. Bien qu'ils puissent demander un peu plus de soins que d'autres espèces, la première récolte gratifiante en vaut la peine. Plusieurs récoltes sont possibles mais peuvent nécessiter un soin supplémentaire.

Receiving & Storage

Remove starter from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive!

Plant & Grow starters should be used within 1 week of receipt. If you don't plan to use immediately, you can refrigerate your block for up to 6 months.

How to Grow

Chestnut mushrooms are slow-growing and richly colored, with firm texture and nutty flavor. While they can be grown outdoors, they require a bit more patience and care than faster-fruiting species.

How to initiate fruiting outdoors:

  • Wait for color change: Allow the block to begin turning orange within the bag before initiating fruiting. This is a sign the mycelium is mature and ready.
  • Cold shock: Place the unopened bag in the refrigerator for about 8 hours before introducing it to the outdoor environment. This cold shock can help trigger pinning.
  • Pick a shady spot: Find a well-ventilated area with indirect light—beneath trees or along a north-facing wall works well.
  • Bury the block: Remove the plastic bag entirely from your block. Bury the block completely, adding about 1" of soil or mulch on top.
  • Maintain moisture: Mist regularly around the block to maintain high humidity. Be consistent—chestnuts are slow to pin and require steady conditions.

Temperature & humidity:

  • Chestnuts prefer cooler temperatures (ideally 55–65°F), so they’re better suited to spring and fall grows in most regions.
  • Avoid overly hot or dry conditions, which can stall growth.
  • These mushrooms are more sensitive to environmental shifts, so try to protect them from wind, sun, and dramatic temperature swings.

Special considerations:

  • Fruiting may take several weeks—be patient and keep humidity high during the wait.
  • The block may produce a single large flush rather than multiple smaller ones.
  • Pigment from the caps can stain lighter-colored mushrooms or surfaces if placed nearby.

Harvesting:

  • Harvest chestnuts before the veil breaks—this means the caps will still be rounded or cupped.
  • Delaying harvest can shorten shelf life and cause mushrooms to lose their firm texture.
  • Use a clean knife or gentle twist to remove clusters without damaging the block.

Chestnuts reward patience with a beautiful and satisfying harvest—rich in color, flavor, and texture.

Growth Parameters

For the best quality mushrooms, try to adhere to these general temperature and fruiting time guidelines.

Pick your spot

Choose a shaded area with soil or mulch. Dig a hole about the size of the starter block, deep enough so it can be fully covered once placed. A cool, protected spot will give you the best results.

Plant the block

Remove the mushroom starter from its bag and place it in the hole. Fill in the sides with soil so there are no gaps, then cover the top with a couple inches of wood chips to help retain moisture.

Watch it grow

Water after planting and keep it lightly watered, especially on dry days. In as little as 1 to 2 weeks, mushrooms begin to appear. Harvest fresh clusters right from your garden.

Frequently Asked Questions

Yes. Plant & Grow blocks are designed for real garden beds. If you can grow vegetables, you can grow mushrooms right alongside them — and they can help support healthier soil and stronger plants over time.

It’s as easy as planting a seedling. Just bury the block, water lightly, and let it grow. No complicated setup or special tools required.

Plant it in shaded areas, along garden edges, or right next to your vegetables and herbs. Anywhere your garden already gets consistent watering works well.

You can start harvesting in as little as two weeks, depending on the variety and conditions. It’s one of the fastest ways to harvest from your garden.

Yes. Mushrooms are resilient and grow in a wide range of climates. If your garden supports vegetables, this will work for you. Plant & Grow varieties are easy to recognize, and look-alikes are unlikely to grow in a garden setting.

Hardier than anticipated!

Growing in SE Wisconsin in 2026, planted in raised beds between eggplants, cucumbers and peppers. After a couple months of nothing, surprised us with the first flush going into a heat wave. Now gracing us with a second flush during a cool rainy weekend. Much hardier than I expected. Delicious roasted with toasted sesame oil as a topper for fried rice and lo mein. Stems have a great texture even after cooking.

Nice crunchy texture!

I live in Los Angeles (zone 10b) and started growing mushrooms in spring of 2026 with the North Spore indoor grow kits. They made it so easy that it was a wonderful experience for me and my little one. Immediately afterward, I tried the "Plant and Grow" blocks in shaded outdoor raised beds. I started with the blue oyster mushrooms, pink oyster mushrooms, and then chestnut mushrooms.

The chestnuts did require a little more attentiveness and I didn't follow exaxt instructions, but they did fruit twice a couple of months after I planted. I will say that we had a few heat waves that were unexpected and I thought I had failed this one. It was a wonderful surprise that after some neglect, they popped up! They were deliciously crunchy and absolutely beautiful! I would definitely plant again when the weather cools down.

Thanks for sharing your experience! We're so glad your chestnuts pulled through despite the heat waves. Wishing you many more successful harvests!
