QUESTION: Can I reuse compost in pots?
ANSWER: Yes, you can reuse compost in pots, but used compost will need to be amended to replace nutrients that were used up in the previous growing season and to improve soil structure which deteriorates overtime.
Old compost can be rejuvenated using one or more of a variety of ingredients, including worm compost, homemade compost, bokashi compost, manure, green waste compost, store bought compost, chicken manure pellets, general purpose organic fertilizer, biochar, and rock dust.
You don’t need to add all of these ingredients by any means, but using one or two can turn your old compost into an excellent growing medium for another year worth of cultivation.
