Some tips for growing a plumeria tree include planting it in a sunny location, using well-drained soil, watering it once a week and fertilizing every two weeks during the growing season. In cold climates, plant it in a pot that can be taken inside when temperatures drop below 33 degrees Fahrenheit. If the temperature falls under 50 degrees Fahrenheit, cover the plumeria tree with a blanket.
Choose a planting location that receives at least light shade, although the plumeria grows best in full sun, and use well-drained soil or work a generous amount of compost into it to improve drainage and add nutrients. The tree only requires enriched soil if the soil in the planting area is especially poor.
When first planting the tree, dig a hole that is at least twice as wide as the root ball. Add compost to the soil in the hole, and carefully set the roots in, spreading them out. Fill in the soil, tamp it down gently, and water the tree well. Give the tree at least 1 inch of water a week or more for a potted plumeria. Prune the tree lightly in the spring, only snipping off leggy or misshapen limbs to maintain the tree's shape.
