WHEN TO START PLANTS IN A GREENHOUSE

For annual flowers and vegetables, starting seeds indoors 6-8 weeks before the last frost date is generally recommended.

This allows ample time for seedlings to establish before transplanting outdoors to garden beds.

Perennial plants typically require a longer growing season to establish roots before winter.

Starting perennial seeds indoors 8-10 weeks before the last frost date ensures robust growth and increased chances of survival.

Tropical plants thrive in warm, humid conditions. Starting tropical plant seeds indoors 10-12 weeks before the last frost date allows sufficient time for germination and establishment before transplanting into the greenhouse.

Climate Zone: Understanding your climate zone is fundamental. This knowledge helps determine the timing for starting plants in a greenhouse.

Plant Variety: Different plants have varying requirements regarding temperature, light, and moisture. cool-season crops, like spinach or broccoli thrive in cooler temperatures, while others, like pumpkins require warmer conditions.

Frost Dates: Knowing the average last frost date in your area is essential for planning when to start plants in a greenhouse.

Growing Medium and Containers: The quality of the growing medium and containers used also influences plant growth. Ensure that the soil is well-draining and nutrient-rich to support healthy root development.

Light Exposure: Proper light exposure is critical for photosynthesis and overall plant health.

Ventilation and Humidity: Maintaining proper ventilation and humidity levels within the greenhouse promotes airflow and prevents fungal diseases.
