Avocados aren't the only kitchen discards that can grow into beautiful plants, says show host Kim Haworth. Also try seeds from citrus and tropical fruit, planting them in rich, fast-draining soil and keeping them warm. Keep in mind that saving different types of seeds requires different strategies, including the following: - Save whole seeds from cut citrus such as lemons or grapefruit, and dry them on a paper towel before planting. Save two or three to make sure you get at least one plant.
- Slice mango fruit away from its seed as best you can, and then soak the seed and any pulp that is still clinging to it in water. After 48 hours, the pulp should pull away easily and you can plant the pit
- Cut passion fruit open, scoop out the seeds, and then leave them to ferment for three or four days before planting.
- Scoop the seeds and pulp from the middle of a papaya (figure A), and let the seeds dry out before planting.
