MI Outdoor Growing Tips
🌱 Container vs Ground
Containers (15-25 gallon fabric pots) give you control over soil quality and let you move plants if needed. In-ground growing can produce larger plants but commits you to that location.
💧 Watering Outdoors
Outdoor plants in hot weather may need daily watering. Water deeply in the morning to avoid mold issues. Mulch around plants to retain moisture and regulate soil temperature.
🐛 Pest Management
Inspect plants daily. Use neem oil preventively during veg. Diatomaceous earth around the base deters crawling insects. Companion planting (basil, marigolds) can help deter pests naturally.
🌧️ Weather Protection
Be ready to cover plants during unexpected rain in late flower (mold risk). Shade cloth helps during extreme heat. Know your first frost date and harvest before it hits.
