Everything it needs
9 essentials at a glance
Watering
Smith's Amanita prefers moist but not soggy conditions.
Water the substrate thoroughly when the top inch feels dry, typically every 1-2 weeks. During dry spells, increase frequency. Signs of over-watering include yellowing caps and a mushy texture, while under-watering may cause shriveling and a dull appearance.
Light
This mushroom thrives in partial shade, ideally receiving 4-6 hours of indirect sunlight daily.
Avoid direct sunlight, as it can scorch the caps. A location under trees or shaded areas is perfect for maintaining the necessary light conditions.
Soil
Amanita smithiana prefers well-draining, rich, organic soil with a pH range of 5.5 to 7.0.
A mix of peat, compost, and perlite can create an ideal potting mix, ensuring good drainage while retaining moisture.
Humidity
Humidity levels should be kept between 60-80%.
To increase humidity, mist the area regularly or place a humidity tray nearby. Signs of humidity stress include dry caps and stunted growth.
Temperature
Ideal temperatures range from 60-75°F (15-24°C).
Smith's Amanita is typically found in USDA hardiness zones 5-8. It can tolerate brief periods of cold but should be protected from frost.
Fertilizing
Use a balanced organic fertilizer with an NPK ratio of 10-10-10, applied every 4-6 weeks during the growing season.
Signs of nutrient deficiency include poor growth and pale caps.
Pruning
Pruning is not typically necessary for mushrooms.
However, remove any dead or decaying material around the base to promote healthy growth. Use clean, sharp tools to avoid contamination.
Repotting
Repotting is not common for Amanita species, as they are typically found in natural settings.
However, if grown in containers, repot every 2-3 years or when the substrate depletes. Signs include poor growth and a compacted substrate.
Propagation
Propagation is primarily through spores.
Collect mature caps, allow them to release spores onto a suitable substrate, and maintain moisture. Best timing for spore collection is during the fruiting season, typically late summer to early fall.

Care through the year
Spring
In spring, monitor moisture levels as temperatures rise. Ensure the substrate remains moist and provide indirect light.
Summer
During summer, maintain consistent watering and humidity. Protect from extreme heat and direct sunlight.
Fall
In fall, prepare for spore collection as caps mature. Continue to maintain moisture and humidity levels.
Winter
In winter, protect from frost and extreme cold. Reduce watering slightly but keep the substrate from drying out completely.
Toxicity & Safety
Smith's Amanita is highly toxic, containing potent toxins that can cause severe gastrointestinal distress and liver failure. All parts of the mushroom are toxic, and ingestion can lead to serious health issues.
