One of the greatest joys of living in Hawaii is the ability to have a lush, tropical landscape in your own backyard. Planning and tending to a tropical garden in our warm, humid climate is not difficult. Here are some easy guidelines for your tropical, Hawaiian garden.

To create that jungle-like environment of a true tropical garden, you’ll want to use a rich mix of textures; dense, large-leafed plants; and, vibrantly-colored flowers. Be sure to plant in soil that is rich in organic matter to help hold moisture in the soil. Add additional organic materials, such as fertilizer, if necessary.

In order to create an abundant appearance, think vertical layers; a canopy of trees, a layer of shrubs and perennials and a final tier of low plants and ground cover.    

The best way to nurture your tropical garden can depend on which microclimate you live in, according to Paul Okuhara of Koolau Farmers Plant Nursery in Kailua. For example, here on or Windward side, in the Keolu Hills area where soil has large amounts of clay in it, it is best to add chicken manure or another soil conditioner. Okuhara recommends Menehune Magic Soil Conditioning.

In wetter areas, such as Maunawili or Kaneohe, it is beneficial to add cinders for drainage so that roots don’t rot. If you live closer to the beach, you’ll need to remove sand and add soil and manure, Okuhara said.

There are many flowering plants that work well in tropical gardens, according to Okuhara. For sunny spots, he recommends gardenias; mountain orchids, which are available in a variety of rich colors; vincas; New Guinea impatiens; and marigolds. For shadier areas, he suggests mondo grass, which is not flowering; guzmania, a type of bromeliad; and palms.
