How to Grow Edible Mushrooms in Your Backyard

Mushrooms are not only delicious and nutritious but also surprisingly easy to grow at home. Unlike traditional garden plants, mushrooms thrive in cool, shady spots, making them perfect for underused areas in your backyard. Whether you want to grow flavorful shiitakes, oyster mushrooms, or gourmet wine caps, cultivating edible mushrooms is an exciting and rewarding hobby.

In this guide, we’ll walk you through the step-by-step process of growing edible mushrooms in your backyard, from selecting the right variety to harvesting your first crop.

1. Why Grow Edible Mushrooms at Home?

Growing mushrooms at home offers a range of benefits:

Fresh, Organic Mushrooms: You control the growing process, ensuring your mushrooms are free of chemicals and pesticides.
Cost-Effective: Store-bought mushrooms can be pricey, especially gourmet varieties. Growing them yourself is more affordable.
Eco-Friendly: Mushrooms can be grown on recycled materials like logs, straw, or coffee grounds, reducing waste.
Low Space Requirements: Mushrooms don’t require large garden beds; they thrive in shaded or indoor spaces.

Pro Tip: Homegrown mushrooms have a richer flavor and better texture compared to store-bought ones.

2. Best Edible Mushrooms to Grow in Your Backyard

Different mushroom varieties have unique growing requirements. Here are the easiest and most popular edible mushrooms for backyard cultivation:

1. Shiitake Mushrooms

Flavor: Rich, meaty, and umami-packed.
Growing Medium: Hardwood logs such as oak, maple, or beech.
Ideal Conditions: Shade, moderate humidity, and cool temperatures.

2. Oyster Mushrooms

Flavor: Mild, slightly sweet, and versatile in cooking.
Growing Medium: Straw, coffee grounds, or hardwood logs.
Ideal Conditions: High humidity and temperatures between 55–75°F (13–24°C).

3. Wine Cap Mushrooms (Stropharia)

Flavor: Earthy and nutty; ideal for soups and sautés.
Growing Medium: Hardwood chips, straw, or garden beds.
Ideal Conditions: Partial shade with moist, nutrient-rich soil.

4. Button Mushrooms

Flavor: Mild and familiar; perfect for raw or cooked dishes.
Growing Medium: Compost or manure-based substrate.
Ideal Conditions: Indoor or shaded outdoor areas with stable temperatures.

Pro Tip: Start with oyster mushrooms if you’re a beginner—they’re low maintenance and quick to grow.

3. Setting Up Your Mushroom Growing Area

Before you start growing mushrooms, set up an environment that mimics their natural habitat. Here’s how:

Choose a Suitable Location

Mushrooms prefer shade and high humidity. Ideal spots include:
- Shady areas under trees
- Damp corners of your backyard
- Basements or sheds (for indoor growing)

Tip: Ensure the area has minimal sunlight exposure and consistent airflow.

Select a Growing Medium

Mushrooms need a substrate—a material that provides nutrients for their growth. Choose the medium based on the type of mushroom:

Hardwood Logs: Best for shiitake and oyster mushrooms.
Straw or Coffee Grounds: Suitable for oyster mushrooms.
Compost or Manure: Ideal for button mushrooms.
Wood Chips: Perfect for wine cap mushrooms.

Pro Tip: Use clean, untreated materials to prevent contamination that may harm mushroom growth.

Prepare Your Mushroom Spawn

Mushroom spawn is essentially the “seed” that grows mushrooms. You can purchase spawn from reputable suppliers in the form of:

Plug Spawn: Small dowels inoculated with mushroom mycelium (ideal for logs).
Grain Spawn: Inoculated grains like rye or millet (for straw or compost-based growing).

Where to Buy: Purchase spawn from trusted sources like North Spore or Field & Forest Products.

4. Growing Mushrooms on Logs (Perfect for Shiitakes)

Logs are a natural substrate for many mushrooms and offer long-term yields. Here’s how to get started:

Step 1: Select and Prepare the Logs

Use freshly cut hardwood logs 3–4 feet long and 6–10 inches in diameter. Avoid softwoods like pine.
Allow logs to rest for 2–3 weeks to eliminate antifungal properties.

Step 2: Inoculate the Logs

Drill holes 1 inch deep and spaced 6 inches apart along the log.
Insert plug spawn into the holes.
Seal each hole with food-grade wax to prevent contamination and moisture loss.

Step 3: Incubate the Logs

Place the inoculated logs in a shady, moist area. Stack them in a crisscross pattern for airflow.
Keep the logs moist by misting them with water regularly.

Timeline: Mycelium colonizes the logs in 6–12 months. Shiitake mushrooms typically fruit after a year.

Pro Tip: Soak the logs in water for 24 hours to trigger fruiting once they’re colonized.

5. Growing Mushrooms on Straw or Coffee Grounds (Great for Oyster Mushrooms)

Oyster mushrooms are one of the easiest varieties to grow, especially if you’re short on space. They thrive in low-cost substrates like straw or used coffee grounds. Here’s how to get started:

Step 1: Prepare the Substrate

Straw: Chop straw into 2–4 inch pieces. Pasteurize it by submerging in hot water (160–170°F) for 1–2 hours to kill contaminants. Drain thoroughly.
Coffee Grounds: Use freshly brewed coffee grounds that are still moist but cooled. They are naturally pasteurized during brewing, making them ready to use.

Step 2: Mix Mushroom Spawn with Substrate

Combine pasteurized straw or coffee grounds with grain spawn in a clean container.
For straw: Fill breathable grow bags, buckets with holes drilled in the sides, or plastic tubs.
For coffee grounds: Add spawn and grounds to containers with airflow holes.

Pro Tip: Layer spawn and substrate evenly to ensure consistent mycelium colonization.

Step 3: Provide Proper Growing Conditions

Place containers in a dark, humid space (like a shed or basement).
Maintain temperatures between 55–75°F (13–24°C).
Mist the substrate regularly to keep humidity levels high (80–90%).

Signs of Progress: Within 2–3 weeks, the substrate will turn white as the mushroom mycelium spreads.

Step 4: Trigger Fruiting

When the substrate is fully colonized:

Move the containers to a spot with indirect light and fresh air.
Continue misting to keep humidity high. Tiny mushrooms (called “pins”) will begin forming in 1–2 weeks.

Step 5: Harvest Your Mushrooms

Mushrooms are ready to harvest when the caps flatten out but before they start curling upward.
Gently twist or cut the mushrooms at the base of the stem to avoid damaging the substrate.

Pro Tip: Oyster mushrooms grow in flushes. After harvesting, mist the substrate and wait 1–2 weeks for the next flush.

6. Harvesting and Storing Edible Mushrooms

Knowing when and how to harvest your mushrooms is essential for maintaining quality and encouraging future flushes.

When to Harvest

Mushrooms are ready when the caps have fully opened but are still firm.
Avoid letting mushrooms overmature, as they will lose flavor and texture.

Visual Cues:

Shiitake: Caps are flat, with edges still curled slightly downward.
Oyster: Caps are broad, and gills are visible underneath.

How to Harvest

Gently twist the mushroom stem at the base to remove it.
Alternatively, use a sharp knife or scissors to cut the stem cleanly.

Storing Fresh Mushrooms

Store mushrooms in a paper bag or breathable container in the refrigerator. Avoid airtight containers, as mushrooms need airflow.
Fresh mushrooms last 5–7 days when stored properly.

Drying Mushrooms for Long-Term Use

Slice mushrooms into thin, even pieces.
Dry them using a dehydrator or by placing them on a rack in a warm, dry area with good airflow.
Store dried mushrooms in an airtight jar for up to 6–12 months.

Pro Tip: Rehydrate dried mushrooms by soaking them in warm water for 20–30 minutes before cooking.

7. Troubleshooting Common Mushroom Growing Issues

Even with proper care, challenges may arise. Here are solutions for common mushroom-growing problems:

1. Mold or Contamination

Cause: Poor pasteurization, lack of cleanliness, or excess moisture.
Solution: Use sterile tools, properly pasteurize the substrate, and maintain good airflow.

2. No Fruiting

Cause: Inadequate humidity, light, or temperature.
Solution: Increase humidity by misting regularly, provide indirect light, and ensure proper temperatures.

3. Dry or Small Mushrooms

Cause: Insufficient humidity or airflow.
Solution: Mist regularly and maintain a consistent environment with fresh air circulation.
