The Ultimate Guide to Growing Pink Oyster Mushrooms (Pleurotus djamor)
Pink Oyster Mushrooms (Pleurotus djamor) are some of the most visually stunning and fastest-growing mushrooms in the gourmet mushroom world. Their vivid pink color, rich umami flavor, and meaty texture make them a favorite among chefs, home cooks, and mushroom enthusiasts alike. Even better, they’re relatively easy to grow with minimal equipment, making them perfect for beginners and small-scale mushroom farmers.
In this comprehensive guide, we’ll cover everything you need to know about growing Pink Oyster mushrooms—from spawn selection and substrate preparation to environmental requirements, harvesting, and storage. We’ll also provide authoritative resources and links to trusted vendors like The Spore Depot to help you get started on the right foot.
What Are Pink Oyster Mushrooms (Pleurotus djamor)?
Pleurotus djamor, commonly known as the Pink Oyster mushroom, is native to tropical and subtropical climates. It’s characterized by vibrant pink fan-shaped caps, decurrent gills, and a fast-growing mycelial structure that thrives in warm temperatures and humid environments.
Unlike many other gourmet mushrooms, Pink Oysters grow in dense, cascading clusters and are highly perishable, so they’re best consumed or processed shortly after harvesting. They’re particularly popular in plant-based dishes thanks to their texture and savory, bacon-like aroma when cooked.
Why Grow Pink Oyster Mushrooms?
✔ Beginner-Friendly – Fast colonization and forgiving conditions
✔ Heat-Tolerant – Ideal for summer or warm indoor climates
✔ High Yield – Multiple flushes with proper care
✔ Eye-Catching – Highly marketable due to bright color
✔ Gourmet Appeal – Delicious flavor and culinary versatility
Where to Get Pink Oyster Mushroom Spawn
High-quality spawn is essential for successful cultivation. You can buy Pink Oyster mushroom spawn in liquid, grain, or sawdust form from reputable sources like:
Choose grain spawn for ease of use and faster colonization, or liquid culture if you plan to inoculate your own sterilized grain.
Substrates for Growing Pink Oyster Mushrooms
Pink Oysters are highly adaptable and can grow on a variety of cellulose-rich substrates, including:
- Straw (wheat, oat, or rice straw)
- Sugarcane bagasse
- Cardboard
- Hardwood sawdust (usually supplemented with bran)
- Coffee grounds (best when mixed with straw or cardboard)
Recommended substrate mix for high yields:
- 80% chopped straw
- 20% wheat bran
- Add water to 60–65% moisture content (feels like a wrung-out sponge)
Pasteurization or sterilization is required to minimize contamination.
Methods for Growing Pink Oyster Mushrooms
You can grow Pink Oyster mushrooms using several methods:
- Bag cultivation (most common and scalable)
- Bucket growing (DIY and beginner-friendly)
- Bottle or jar cultivation (less common, visually appealing)
Bag cultivation using pasteurized straw is the most accessible method and works well for small-scale indoor or outdoor growing.
Step-by-Step Guide to Growing Pink Oyster Mushrooms
Step 1: Substrate Preparation
Chopping and Pasteurizing Straw:
- Cut straw into 1–3 inch pieces.
- Pasteurize by soaking in hot water (160–170°F / 71–77°C) for 1–2 hours.
- Drain and let cool to room temperature.
Alternative: Use pre-pasteurized blocks or sterilized sawdust blocks available at The Spore Depot.
Step 2: Inoculation
Once your substrate is cool, mix in Pink Oyster mushroom spawn at a 5–10% spawn rate by weight. For example, use 100g of spawn per 1kg of substrate.
Instructions:
- Wear gloves and work in a clean environment.
- Mix spawn evenly throughout the substrate.
- Pack into filter patch grow bags or plastic buckets with air holes.
Seal the containers and label them with the date and mushroom strain.
Step 3: Incubation (Colonization Phase)
📍 Ideal Conditions:
- Temperature: 75–85°F (24–29°C)
- Humidity: 70–80%
- Light: Not required during colonization
- Duration: 7–14 days
You’ll know colonization is complete when the substrate turns white with dense mycelial growth. You may also see small pins beginning to form inside the bags.
Step 4: Fruiting Conditions for Pink Oyster Mushrooms
Once fully colonized, it’s time to introduce fruiting conditions to encourage mushroom development.
📍 Fruiting Parameters:
- Temperature: 70–85°F (21–29°C)
- Humidity: 85–95%
- Light: Indirect light or fluorescent light for 12 hours/day
- Fresh Air Exchange: 3–5 times per day to prevent CO₂ buildup
Cut 1–3 slits into the grow bag or uncover bucket holes to allow mushrooms to emerge. Mist frequently or use a humidifier to maintain high humidity.
Pink Oyster mushrooms will start pinning within 3–5 days and mature rapidly.
Step 5: Harvesting Pink Oyster Mushrooms
Harvest when:
- Caps are 2–4 inches wide
- Edges are slightly curled
- Clusters are firm and richly colored
Use a clean knife to cut clusters at the base. Be sure to harvest before the caps flatten completely or begin to fade in color, as older mushrooms become fragile and lose flavor.
Step 6: Storage and Use
Pink Oyster mushrooms are highly perishable due to their delicate structure.
📦 Storage Tips:
- Store in paper bags in the refrigerator for up to 3–5 days
- For longer storage: dehydrate at 110°F (43°C) and store in airtight containers
- Cook immediately after harvesting for the best flavor and texture
🍽 Popular preparations:
- Stir-fried with garlic and soy sauce
- Grilled or pan-seared as a meat substitute
- Added to curries, soups, and noodle dishes
Expected Yield from Pink Oyster Mushroom Cultivation
A well-colonized 5 lb fruiting block can yield:
- 1.0–1.5 lbs of fresh mushrooms over 2–3 flushes
- Flushes usually occur every 7–10 days with rest periods in between
Proper care and rehydration between flushes (light soaking or misting) can improve yield and mushroom quality.
Common Issues When Growing Pink Oyster Mushrooms
❌ Dry caps or cracking
Cause: Low humidity
Fix: Increase misting and monitor humidity levels
❌ Thin or leggy mushrooms
Cause: Inadequate fresh air exchange
Fix: Increase ventilation or open more bag slits
❌ Contamination (green or black mold)
Cause: Poor pasteurization or excess moisture
Fix: Improve substrate preparation and sterilization techniques
Safety Note on Consumption
Always cook Pink Oyster mushrooms thoroughly before eating. Raw or undercooked Pink Oysters can be hard to digest and may cause mild gastrointestinal discomfort in some individuals.
