How to Grow a Bush Allamanda

The bush allamanda (Allamanda schottii) is a flowering evergreen shrub indigenous to Brazil. It grows up to 4 feet tall and spreads to approximately the same size in diameter. The compact shrub produces bright yellow, tubular blooms from mid-summer until early fall. It performs best in full sun and fertile soil that doesn't remain soggy. Bush allamanda is hardy in U.S. Department of Agriculture Zones 10 and 11, but may be grown as a patio plant in cooler regions if taken indoors for the winter.

Instructions

    • 1

      Dig a hole that is wide enough to contain the roots without bunching and deep enough to plant them at their original depth.

    • 2

      Replace one-half of the garden soil removed from the planting hole with organic compost.

    • 3

      Water until the soil and compost mixture feels very moist, but not soggy.

    • 4

      Place 3 inches of mulch around the new planting to discourage weeds and prevent moisture loss.

    • 5

      Provide supplemental water when the top 1/2 inch of soil feels dry.

    • 6

      Feed with balanced water-soluble fertilizer each week during the growing season. Consult package directions for precise rates of application, as this may differ between products.

    • 7

      Cut off blooms when they fade to encourage new buds to form.

    • 8

      Prune in late winter to manage the size of bush allamanda and to eliminate unsightly or damaged branches.
