Gardening advice: Best practices for harvesting seeds and crops

Seasonal gardening advice highlights the importance of timing for harvesting seeds and crops to ensure quality and longevity.

For seed collection, gardeners should look for plants with dry seed heads, such as sunflowers, marigolds, cosmos, and poppies. The Royal Horticultural Society recommends gathering seed heads on dry days once seeds have matured but before they begin to scatter. Vegetable seeds, including beans, peas, tomatoes, and peppers, can also be saved by selecting healthy, high-performing plants. It is crucial that seeds are completely dry before being stored in paper envelopes or bags in a cool, dry location. Note that offspring from F1 hybrid plants may not possess the same characteristics as the parent plant.

Regarding potato harvesting, gardeners are cautioned against premature digging. While yellowing and drying foliage may signal the end of the season, harvesting too early can result in thin skins that are easily damaged, reducing the tubers' shelf life for winter storage. To determine maturity, gardeners should perform a test by digging up a single tuber to check the skin's firmness and thickness.
