How to Grow Cuban Oregano

The Cuban oregano (Plectranthus amboinicu) is a tropical herb. Like all members of the mint family, Cuban oregano is very easy to grow and reaches a mature height of 2 feet with stout, square stems and lightly serrated leaves of a jade-green color. Cuttings provide the quickest and most reliable means of growing Cuban oregano plants, but they must be started during the warm summer months to ensure reliable rooting.

Things You'll Need

  • Potting soil
  • Coarse sand
  • 4-inch deep plastic pot
  • Pruning shears
  • 0.1 percent IBA (indolebutyric acid) rooting hormone
  • 1-gallon plastic bag

Instructions

    • 1

      Combine potting soil and coarse sand in equal measures. Pour small amounts of water over the components while mixing them. Continue adding water until it feels moderately moist throughout.

    • 2

      Fill a 4-inch deep plastic pot with the soil-and-sand mixture. Pressing it firmly into the pot removes air bubbles. Leave a 1-inch gap between the soil and the pot's lip.

    • 3

      Poke a 2- to 3-inch deep hole in the soil's center. Use a pencil or your finger to create the hole.

    • 4

      Take a 4- to 6-inch long tip cutting from an existing Cuban oregano plant. Choose one with healthy foliage, an unblemished stem and no flowers.

    • 5

      Sever the cutting right beneath a set of leaves. Pinch it off or make a clean, straight cut using pruning shears.

    • 6

      Strip the lower leaves defoliating the Cuban oregano cutting's entire bottom half. Discard the leaves or use them in cooking.

    • 7

      Dip the leafless portion of the stem in 0.1 percent IBA rooting hormone. Shaking the cutting removes any surplus powder.

    • 8

      Insert the Cuban oregano cutting's base into the rooting pot, using the preformed hole. Press the soil in around the stem.

    • 9

      Place the potted cutting on a windowsill with northerly or easterly exposure where it receives bright but indirect sunlight.

    • 10

      Place a 1-gallon plastic bag over the Cuban oregano cutting holding moisture and warmth around the remaining foliage.

    • 11

      Adding a few spoonfuls of water to the soil mixture, as needed, maintains moisture at a 1-inch depth.

    • 12

      Check for roots in approximately three weeks. Transplant the rooted Cuban oregano cutting into a permanent pot or directly into a garden bed in frost-free areas.
