Q:

How do you grow an allamanda shrub?

A:

The most common allamanda, the bush allamanda, is an attractive evergreen shrub that produces abundant yellow flowers. Allamanda can be grown as a landscape plant in Zone 10 or in a container or greenhouse in other zones.

  1. Choose a site and prepare the soil

    Allamanda shrubs need plenty of sunshine and should be placed at least 30 inches from a house or other structure. If you are planting more than one, plant them at least 3 feet apart.

  2. Prepare the soil and plant

    For a landscape plant, dig a hole large enough to allow the roots to spread. Amend the soil with commercial topsoil, cow manure or organic peat moss. If you are planting your allamanda in a container, use a high-quality potting mix.

  3. Water regularly

    Water allamanda shrubs regularly but do not overwater. Allow the soil to dry out slightly between waterings. Water container plants frequently enough to keep the soil moist in summer. Let them dry out more during the winter.

  4. Fertilize and prune

    Fertilize your allamanda with a good-quality granular fertilizer in the spring, summer and fall. Trim the plant in the spring after flowering. You can prune young plants to 3 feet tall. Allow mature plants to grow to at least 4 or 5 feet.
