Maintain Your Plants
Sow squash and cup-and-saucer plant seeds under cover in mid-spring, in either a warm room or a heated propagator. Passion flowers are readily available as plants and will persist as perennial climbers in warm gardens. Attach wires or trellis to a bare fence, so the climbing plants can be tied in or use their own tendrils for support.
After the last frost date, plant the young plants about 12 inches away from the base of the fence, about 18 inches apart, and water them well. Tie the stems to the supports when they are long enough, after which the passion flower and cup-and-saucer plant should find their own way, while the squash may need further tying in. Water the squashes regularly once fruits have formed.
