Moving Your Seedlings Outdoors

Before transplanting your small sprouts from your AeroGarden to you soil beds outdoors, seedlings need to be hardened off. This means helping the plants get accustomed to strong sunlight, cold nights, and less watering over time. Skipping this step will almost certainly result in some or all of your plants dying! Hardening off seedlings eases their transition from the AeroGarden to the outdoors, where they will be exposed to full sunlight, temperature variations and wind.

Tips for Successful Transplanting

  • Remove the Bowl with seedlings from the Base and place it outside in a shady location for a few hours each day, gradually increasing to 24 hours outside. This should take about a week. Too much direct sun will kill your seedlings, so be sure to pick a spot with shade.
  • Bring the Bowl inside if weather turns bad or temperature is below 45°F (7.2°C). 
  • Return the Bowl to the AeroGarden Base when you bring the Bowl inside.
  • If your seedlings get too large before weather will allow transplanting outdoors, transplant into small pots in a high quality potting mix such as Miracle-Gro. Keep them fully watered in a sunny space until weather permits transplanting outdoors.
  • Once you've hardened your seedlings, simply dig a hole in the soil, remove the plant and (including the roots and grow sponge) from the space in the seed starting tray, and place it in the hole you just dug in the soil. Fill in the hole gently, surrounding the roots and the bottom of the stalk.
