How to Grow Sunflowers With Morning Glories

Sunflowers and morning glories are both colorful flowering plants. When you combine them, the tall, strong stalk of the sunflower serves as an excellent support for the vining morning glory. Because both plants are summer annuals, you needn't fear harming either one at the end of its growing season -- because you must pull them when the weather turns cold. If you plant sunflowers around the border of a garden bed, it will create a "sunflower house" for children. The morning glory vines will help enclose it.

Instructions

    • 1

      Purchase seeds of a tall variety of sunflower. Any type of morning glory will be suitable. Then measure the area where you want to plant your sunflower house: An appropriate size is 4 feet wide by 8 feet long. Mark the edges with rocks or sticks -- or sprinkle flour along the edges.

    • 2

      Cover the planting area with 2 to 3 inches of organic compost and then dig it in, thoroughly mixing it into the soil. Rake the area even.

    • 3

      Soak morning glory seeds in a bowl of tepid water for about 12 hours before you plant.

    • 4

      Dig small holes around the outer edge of the planting area. Make holes 1 inch deep and 12 inches apart, using your trowel. Then plant one sunflower seed in each hole.

    • 5

      Plant one or two morning glory seeds 2 to 3 inches away from each sunflower seed on opposite sides of the sunflowers.

    • 6

      Water the planted area well by running a sprinkler for about 20 minutes. Keep the soil moist until germination occurs and seedlings begin to grow. From that point, water when the soil becomes dry.

    • 7

      Twist morning glory vines onto the sunflower stalks when they begin to form vines. After you help the vines onto the sunflowers, they will wrap around the stalks by their own power.
