Plumerias are tropical trees famous for their gorgeous flowers which are used to make leis (floral garlands). In regions with cold winters, plumerias can be grown in containers and brought indoors when the weather cools in autumn. Other common names are frangipani and Hawaiian lei flower.
Plumerias are EASY to grow. Can be grown in containers or planted in the soil. These plants need to be brought in before the first frost. Choose a sunny spot with well draining soil. Out-or-doors, plant in spring. Space plants 10 to 20 feet apart, depending on the expected mature size of the plant. Dig a hole only as deep as the root ball and 2 to 3 times as wide. If your soil is in very poor condition, amend the soil you've removed from the hole with a small amount of compost. Otherwise don't amend it at all. Carefully remove the plant from the container and set it in the hole. Fill the hole half full with soil, then water it well to settle the soil and eliminate air pockets. Let the water drain, then fill the remainder of hole with soil and water thoroughly. Care Plumerias require at least 1 inch of rain (or equivalent watering) each week. More water may be required for plumerias growing in containers, but don't overwater or the trunks will rot. Feed plants twice a month during the growing season with a high phosphorous fertilizer. Plumerias normally require little pruning, but any shaping should be done in spring. Plumerias are sensitive to cold and should be protected when temperatures dip into the 40Fs. Check periodically for pests such as spider mites, white flies, and mealybugs. Use a horticultural oil or insecticidal soap to control these pests.
