Mushroom Seeds, King Bolete Mycelium Spawn Dried Spores Kit for Planting

King Bolete Mushroom Growing Guide (Boletus edulis)

Key Attributes:

• Type: Wild, gourmet, and highly prized edible mushroom
• Growth Habit: Mycorrhizal (grows in symbiosis with trees)
• Preferred Trees: Oak, pine, fir, spruce, and beech
• Fruiting Season: Late summer to fall (dependent on temperature and moisture)
• Uses: Culinary delicacy in soups, sauces, risottos, and drying for storage

Planting Instructions:

1. Choosing the Right Location:

• King Bolete mushrooms require living trees for symbiosis.
• Ideal locations: Near oak, pine, fir, spruce, or beech trees with rich, moist, well-draining soil.
• Shaded or dappled sunlight areas work best.

2. Preparing the Growing Area:

• For Spores:
  • Collect or purchase dried spores and mix them with non-chlorinated water.
  • Optionally, add a small amount of molasses or sugar to the water to encourage spore activation.
• For Mycelium Spawn:
  • Prepare the soil by loosening the top 2-4 inches and adding decomposed organic matter like leaf litter or compost.
  • Spread the mycelium spawn into the soil around tree roots.

3. Planting & Inoculation:

• Spore Slurry Method: Pour the mixed spore solution around the base of host trees.
• Mycelium Spawn Method: Gently rake the mycelium into the soil, keeping it moist.
• Cover with a light layer of forest mulch to retain moisture.

Growing Conditions & Care:

• Moisture: Keep the area damp but not waterlogged. Regular misting or natural rainfall is ideal.
• Temperature: Optimal growth occurs at 50-70°F (10-21°C).
• Patience Required: King Bolete mushrooms may take 1-2 years to establish before producing fruit.
• Natural Growth: These mushrooms grow best in forest-like conditions with minimal disturbance.

Harvesting & Storage:

• When to Harvest:
  • Pick when caps are fully formed but still firm (usually late summer to early fall).
  • Avoid overripe mushrooms with spongy or decayed caps.
• Harvesting Method:
  • Gently twist or cut at the base without disturbing underground mycelium.
• Storage:
  • Fresh mushrooms last up to 7 days in the refrigerator.
  • Drying is the best long-term preservation method—slice and dehydrate for months to years of storage.
