Mulch with 2 inches of wood chips to preserve moisture.

Step 2

Adjust your watering schedule during hot, windy weather and water more if your Passion flower is in a pot. Fertilize the flower every three to four weeks with a liquid fertilizer made for flowers.

Step 3

Plant the flower 6-to-12 inches from a fence, trellis or wall. Passion flowers climb to a height of 12 feet or more in the space of one summer, depending on the species. They will attach themselves to the nearby object through tendrils.

Step 4

Bring the passion flower indoors when the first frost threatens. Cut the plant back hard to 6-to-8 inches tall and keep it in a cool place so it remains dormant for three or four months. Water it every three or four weeks to keep the soil slightly moist.

Step 5

Place the Passion flower in a warm, bright location when March arrives. Water it once per week until it's thoroughly moist and fertilize it every three or four weeks with a liquid fertilizer made for flowers.
