Choosing a Location for Outdoor Growing

When growing magic mushrooms outdoors, choose a location that mimics their natural habitat:

• Warm, humid climate: Magic mushrooms thrive in tropical and subtropical regions.
• Shaded area: Avoid direct sunlight, which can dry out the substrate.
• Well-drained soil: Mushrooms need moisture but not standing water.
• Near manure or decaying wood: Many species grow on dung or wood chips.

Preparing the Substrate

For outdoor growing, you can use:

• Manure-based substrate: Cow or horse manure mixed with straw.
• Wood chips: For species like Psilocybe cyanescens.
• Pre-made grow bags: Bury colonized grow bags in the soil.

Step 1: Prepare the Substrate

Mix the substrate with water to achieve the right moisture level (like a wrung-out sponge).

Step 2: Inoculate

Mix the substrate with spawn (colonized grain or mycelium) or bury a colonized grow bag.

Step 3: Cover

Cover the inoculated substrate with a thin layer of soil or casing material.

Step 4: Water

Water the area regularly to maintain moisture.

When to Plant

The best time to plant outdoor magic mushrooms depends on your climate:

• Spring: In temperate regions, plant in spring after the last frost.
• Summer: In tropical regions, plant at the beginning of the rainy season.
• Fall: In cooler regions, plant in fall for a spring harvest.

How Long Does It Take to Grow?

Outdoor magic mushrooms typically take 4-8 weeks to grow, depending on the strain, climate, and conditions.

Use organic pest control methods to protect your crop.
