How to grow fragrant frangipanis

Frangipanis, (also known as plumeria), are a popular and beautiful addition to any outdoor space and are known for their fragrant and colourful flowers. They lose their leaves in winter, but don’t be sad! What’s left looks like a funky, living sculpture in your garden, until the leaves reappear in spring!

Growing and caring for frangipanis is not difficult – even for those who don’t have a green thumb!  

You will need a little patience as they are slow growers (only about 20cm a year). This, along with their small root ball, makes them ideal for planting around pools, in garden beds, containers and beside walls, as you won’t have to worry about the roots getting into any structures.

  • Choose a sunny location with well-drained soil. The plant should be placed in a spot where it will receive at least six hours of direct sunlight each day.  
  • Water regularly and allow to drain thoroughly. Frangipanis aren’t keen on soggy roots, so be sure to let the soil dry out completely between watering.
  • To encourage healthy growth and lots of blooms, frangipanis should be fertilised regularly. A balanced, slow-release fertiliser is recommended every four to six weeks during the growing season.
  • Regular pruning will promote healthy root growth. Cut back the branches to just above the nodes and be sure to remove any dead or damaged leaves.

Pests and diseases

  • Frangipanis are generally resistant to pests and diseases, but it is still important to keep an eye out. Powdery mildew and scale insects can be a problem, so be sure to check the plant regularly for any signs of infestation. If you notice any issues, use insecticidal soap to control the pests, or you can opt for natural remedies like neem oil. Natural ways to get rid of pesky pests in your garden
  • During wet and cool weather frangipanis can be at risk of frangipani rust, a root, branch, and tip rot caused by a fungus. Signs include the stems becoming soft, so every now and again, squeeze the stems — firm stems mean you have a healthy tree.
  • To reduce the risks, avoid watering your frangipani in winter. Also, if the stem becomes wrinkled the tree is not well — stop watering and spray leaves with AntiRot. If you notice spongy stems, remove the stem completely to the junction with a main branch.
  • Thinning out 15 to 20 per cent of the canopy of your mature frangipani is good to do every few years; it opens the branches, allows light in and reduces stem rot.
