The most important factor for any pot is drainage, so make sure your pot has plenty of holes in the bottom and don’t be afraid to drill out a few more if needed.
Most standard potting soils will work fine, but those made to hold more moisture may need to be mixed with a little mulch to promote better drainage.
If you would rather go the route of starting your plants from seeds, do so inside about eight to ten weeks before the last frost date for cooler climates.
Keeping your plants in a sunny location and moving them inside on cool nights will help them grow faster and stronger.
Check your containers at least twice a day and water well when the top layer of soil begins to dry.
