How To Grow Bell Peppers In Containers At Home? https://youtu.be/m5rP4hecPCg =============== Bell peppers can be started from seeds, but they love to be warm, so it’s best to start them indoors about 8-10 weeks before the final frost. Seedlings can take anywhere several weeks to appear, so patience is key. Again, warmer is better, and you’ll see better results if you use a heat mat or heated propagator. Bell pepper seeds may be planted outdoors, but there must be no risk of cold weather. It’s best to wait 2-3 weeks after the last frost before planting seeds outside. Keep in mind you’ll want to have a long growing season ahead of you, as peppers can take two or more months to be ready for harvest.
