An annual that has finished its season does not need to be kept alive indefinitely. When flowering and healthy growth are over, clearing the pot creates room for the next appropriate planting.
Check before emptying
Identify whether the plant is truly an annual or a tender perennial you might choose to overwinter. Look for disease or pest problems before deciding where the old plant material and mix should go. Questionable material should not automatically enter a cool home compost pile.
Remove plant remains, loosen the root mass, and assess the mix. A heavily rooted, compacted, salty, or suspect mix may not be suitable for another container crop without further consideration. Do not tip it into drains or natural areas.
Put equipment away ready to use
Wash empty containers, clear drainage openings, and dry them before storage. Follow suitable cleaning and disinfection guidance where disease was involved. Store frost-vulnerable pots under protection according to their material and maker's advice.
Finally, keep the variety name and one short note about how it performed. A pot that was beautiful but needed watering twice as often as you could manage may call for a different design next year. Ending a planting thoughtfully is part of learning to garden, not an admission that you failed to keep it going.
