Planting & care

How to Plant and Care for Royal Cape® Plumbago

Planting Instructions

In-Ground Planting:

  • Location: Choose a sunny spot with well-draining soil. Plumbago prefers full sun but can tolerate partial shade.
  • Soil Prep: Loosen the soil to a depth of 12 inches and mix in compost if the soil is poor.
  • Digging the Hole: Dig a hole twice as wide as the root ball and just as deep.
  • Planting: Place the plant in the hole, making sure the top of the root ball is level with the ground. Backfill with soil and press down gently.
  • Watering: Water deeply right after planting and keep the soil evenly moist for the first few weeks.

Container Planting:

  • Pot Selection: Use a container with drainage holes.
  • Soil: Use a well-draining potting mix.
  • Watering: Water when the top inch of soil feels dry.

Care and Maintenance

  • Watering: Once established, water deeply once or twice a week. Drought-tolerant but benefits from regular watering in extreme heat.
  • Fertilizing: Apply a balanced fertilizer (10-10-10) monthly during the growing season.
  • Pruning: Trim lightly to control shape and encourage more blooms.
  • Cold Protection: In zones below 9, bring containers indoors or protect with mulch.

Pollination and Blooming

Attracts butterflies and bees. Deadhead spent flowers to encourage continuous blooming.

Royal Cape® Plumbago is low-maintenance and perfect for adding vibrant color to your garden!
