Best Roommates 9

Comfrey

Comfrey grown nearby provides biomass for mushroom substrate. Its deep roots don't compete with surface-level mushroom operations.

Tomato

Tomato plants and mushroom beds can coexist if beds are in shaded areas. Mushrooms don't compete for light and can utilize compost from tomato debris.

Pepper

Peppers thrive in full sun while mushroom beds need shade—they complement each other spatially. Mushroom compost enriches soil for pepper beds.

Chives

Perennial chives grow in partial shade, perfect for positioning near mushroom growing structures. Minimal interference with mushroom cultivation.

Mint

Mint thrives in shade and moist conditions—both provided by mushroom growing areas. Keep mint contained to prevent spread.

Lettuce

Lettuce appreciates the dappled shade mushroom structures provide. Mushroom beds create a microclimate perfect for cool-season greens.

Spinach

Spinach grows well in the humidity and shade near mushroom beds. Both prefer cool conditions and moist environments.

Borage

Borage attracts pollinators and beneficial insects. Positioning near mushroom areas doesn't interfere with fungal fruiting.

Parsley

Parsley tolerates shade and benefits from the moisture near mushroom growing areas. No competition for nutrients or light.

Keep Your Distance 3

Squash

Squash and melons attract similar flying insects that contaminate mushroom beds. Humidity requirements conflict.

Watermelon

Melons require full sun and dry conditions—opposite of mushroom requirements. High humidity near melons causes rot.

Cabbage

Brassicas attract the same fungus gnats and flies that infest mushroom beds. Cross-contamination and pest pressure increases significantly.

Growing Guide

🌱 Planting

  • Start seeds indoors 6-8 weeks before last frost
  • Transplant when soil reaches 65°F (18°C)
  • Space plants 18-24 inches apart
  • Plant in well-draining, rich soil with pH 6.0-6.8

💧 Water & Soil

  • Water deeply 1-2 inches per week
  • Mulch to retain moisture and prevent weeds
  • Consistent watering prevents fruit cracking
  • Avoid wetting foliage to prevent disease

☀️ Light & Temperature

  • Requires 6-8 hours of direct sunlight daily
  • Ideal temperatures: 70-85°F (21-29°C)
  • Protect from strong winds
  • Use row covers in cooler climates

🌿 Care & Maintenance

  • Stake or cage plants for support
  • Prune suckers below the first flower cluster
  • Fertilize every 2-3 weeks during fruiting
  • Monitor for common pests and diseases

Harvesting & Storage

🍅 When to Harvest

  • Harvest when fully colored but still firm
  • Ripe when gently pressed gives slightly
  • Best flavor developed at room temperature
  • Check daily during peak season

🏠 Storage Tips

  • Store at room temperature out of direct sun
  • Avoid refrigeration (cold ruins flavor/texture)
  • Use within 5-7 days for best quality
  • Can be frozen, canned, or dried for preservation

Troubleshooting Guide

🐛 Common Pests

  • Hornworms: Hand-pick or use Bt
  • Aphids: Spray with soapy water
  • Whiteflies: Use yellow sticky traps
  • Spider Mites: Increase humidity, use neem oil

🦠 Common Diseases

  • Early Blight: Remove affected leaves, improve airflow
  • Blossom End Rot: Ensure consistent calcium supply
  • Cracking: Maintain even watering
  • Powdery Mildew: Increase air circulation
