Make three decisions at harvest
An apple crop is easier to manage when you decide what to eat soon, what to cook promptly and what might suit storage. In a British garden, note the variety if known. Apples differ in keeping quality, so a mixed harvest should not be treated as one uniform batch.
Inspect each fruit
Look for bruising, punctures, rot and other damage before setting aside storage fruit. Handle gently and use suitable clean containers. Keep sound fruit separate from suspect material. Do not put damaged apples into long storage and assume that a cooler room will resolve the problem.
Check the actual storage location
Assess temperature changes, ventilation and protection from pests. A shed or garage may be unsuitable at some points in the season, especially if it contains chemicals or experiences extremes. Choose an appropriate method for the variety and follow reliable fruit-storage guidance.
Inspect and use the stock
Set a recurring reminder to check the stored fruit and remove deterioration promptly. Record which varieties kept well and which were better used early. Plan meals around the fruit that needs attention first. A smaller, well-managed store can prevent more waste than packing every available box.
