Give your garden a little mushroom magic. The Snow Oyster 'Plant & Grow' Mushroom Starter Block makes it easy to add homegrown mushrooms to your outdoor growing space, whether you’re expanding a garden bed or trying mushroom cultivation for the first time.

This starter block is made with Pleurotus ostreatus and USDA Certified Organic. Its established mycelium is ready to grow, so you can focus on helping the block settle into its growing spot rather than starting from scratch.

Snow Oyster mushrooms are prized for their delicate flavor and tender texture. Freshly harvested, they’re a lovely choice for everyday cooking, from quick sautés to savory vegetable dishes.

Plant & Grow blocks are a practical fit for outdoor growers who want to work mushrooms into a garden bed or another suitable growing area. Mushroom cultivation complements the slower, hands-on pleasures of gardening, with the added reward of harvesting food from your own space.

Why grow Snow Oysters?

  • USDA Certified Organic mushroom starter block
  • A ready-to-grow option for outdoor cultivation
  • Delicate flavor and tender texture for the kitchen
  • An approachable way to explore growing mushrooms at home

New to mushroom growing? You don’t need a lab setup to begin with a Plant & Grow block. North Spore’s mycologist-led approach and educational resources help make mushroom cultivation more accessible, while the block offers a tangible, garden-friendly place to start.

As with any outdoor grow, results depend on growing conditions and care. Choose a suitable garden spot and follow the included planting guidance to give the block a good start. The visible mycelium is part of the living foundation that supports mushroom growth.

At $29.99, the Snow Oyster 'Plant & Grow' Mushroom Starter Block brings together a satisfying garden project and a flavorful harvest. It’s a natural fit for curious gardeners, home cooks, and anyone ready to explore a new corner of homegrown food.

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

Oyster mushrooms are vigorous, fast-growing, and perfect for new outdoor cultivators. With their dramatic colored caps and savory flavor, they bring both beauty and bounty to shaded garden spaces.

How to Initiate Fruiting Outdoors

  • Choose a shaded location: Find a cool, humid spot like under trees, beside a fence, or in a sheltered garden bed.
  • Bury your block: Remove the plastic entirely from your block. Bury the block completely and cover with about 1" of soil or mulch.
  • Maintain consistent moisture: Mist the surrounding soil or mulch regularly (1–2x daily in dry weather) to prevent the block from drying out.

When to Plant

  • Most Oysters thrive in cooler temperatures (ideally 55–65°F), and Pink Oysters like it a little warmer (ideally 70-80°F ).

Special Considerations

  • Watch for rapid growth—oysters can mature quickly and drop spores if not harvested in time.
  • Consider placing straw or leaf mulch around (not on) the block to help regulate humidity without suffocating airflow.

Harvesting

  • Pick clusters when cap edges are still curled under for best texture, flavor, and shelf life.
  • Harvest young to reduce spore production and improve storage.
  • Use both hands or a clean knife to gently remove entire clusters without damaging the substrate.

With minimal effort, oysters will often produce multiple flushes—making them one of the most rewarding mushrooms to grow in the garden.

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.
