Tree Morning Glory: Growing Giants From Seed and Stem

The Tree Morning Glory (Ipomoea arborescens) isn’t your typical morning glory vine. This botanical marvel stands tall as a small tree, boasting magnificent white trumpet-shaped flowers that grace the landscape with a breathtaking display. If you’re looking for a unique and rewarding addition to your garden, propagating your own Tree Morning Glory is both achievable and satisfying. Let’s explore the two primary methods:

1. Starting from Seed: A Journey of Patience and Reward

Propagating Tree Morning Glory from seed is an adventure in patience, but the results are well worth the wait. Here’s how:

a) Sourcing Seeds:

You can collect seeds from existing Tree Morning Glory plants or purchase them online from reputable suppliers. Look for plump, dark-colored seeds which indicate viability.

b) Preparing for Sowing:

  • Scarification: Due to the seed’s hard outer shell, gently nicking it with a nail clipper or lightly sanding a small section improves germination rates.
  • Soaking: Soak the seeds in warm water for 12-24 hours to further encourage the germination process.

c) Planting the Seeds:

  • Timing: Start your seeds indoors 6-8 weeks before the last expected frost in your region.
  • Soil: Choose a well-draining seed starting mix.
  • Depth: Plant seeds about 1/2 inch deep in moist soil.
  • Environment: Maintain a warm environment (70-75°F) and keep the soil consistently moist but not waterlogged.

d) Germination and Care:

  • Germination Time: Expect germination within 1-3 weeks, sometimes longer. Be patient!
  • Light: Once seedlings emerge, provide them with ample sunlight or grow lights for at least 6 hours daily.
  • Watering: Water regularly, allowing the topsoil to dry slightly between waterings.
  • Transplanting: Once the seedlings are a few inches tall and all danger of frost has passed, you can transplant them outdoors into larger pots or directly into the ground.

2. Propagation from Stem Cuttings: A Faster Track to Growth

For those seeking quicker results, propagating Tree Morning Glory from stem cuttings offers a gratifying alternative:

a) Taking the Cutting:

  • Timing: Early morning is ideal as the plant’s moisture content is highest.
  • Selection: Choose healthy, non-flowering stems that are about 6-8 inches long.
  • Cutting: Make a clean cut just below a leaf node, using a sharp, sterilized knife or pruning shears.

b) Preparing the Cutting:

  • Remove Leaves: Strip off the lower leaves to prevent them from rotting in the soil or water.
  • Optional: Rooting Hormone: While not essential, dipping the cut end in rooting hormone can promote faster root development.

c) Rooting in Water or Soil:

  • Water: Place the cutting in a glass or jar of water, ensuring that at least one node is submerged. Change the water every few days.
  • Soil: Plant the cutting in a well-draining potting mix, burying at least one node. Keep the soil consistently moist.

d) Transplanting:

  • Signs of Growth: Once roots have developed (within a few weeks), you can transplant the cutting into a larger pot or directly into the ground.
  • Hardening Off: If you rooted the cutting in water, gradually acclimate it to outdoor conditions before planting outdoors.

A Few Final Tips for Success:

  • Location, Location, Location: Choose a sunny spot with well-drained soil for your Tree Morning Glory.
  • Support Structure: While young, the tree might benefit from a stake for support. As it matures, it develops a sturdy trunk.
  • Pruning: Regular pruning helps maintain its shape and encourages bushier growth.

With a little patience and the right care, you’ll soon be rewarded with the majestic beauty of your very own Tree Morning Glory, a true testament to the wonders of plant propagation.
