Cold Weather? No Problem
Just because it’s become cold outside doesn’t mean you have to put the garden spade away. The good news is that this greenhouse (Planta) is very well isolated, so the cropping can keep on multiplying.
Best winter crops to grow:
- Spinach
- Kale
- Lettuce
- Carrots
- Radishes
Quick Tip: Want to keep your garden warmer? You might experiment with raised beds, thermal mass in the guise of water barrels, or, indoors, below the soil line, there is a small greenhouse heater to keep things cozy on the really cold nights.
