Light Requirements

Frangipani Plant grows best under bright light with at least 4 hours of sunshine. However, keep it away from hot direct sunlight to avoid sunscorch on the leaves.

Red Jasmine will not flower if grown under too little light, therefore, consider investing in a grow light if the natural lighting is not adequate.

Watering

Water Frangipani liberally during the growing season and allow the top 2-3 in. of soil to dry out between waterings to maintain the soil moderately moist.

Cut down on watering during the cold season to maintain the soil slightly moist as growth is minimal at this time.

Ensure that the pot has a drainage hole inorder to prevent the soil from getting soggy as it can lead to root-rot.

Temperature

Average room temperature with a minimum of 13⁰C is ideal for Frangipani Plant. Keep it away from draughts to avoid crispy leaf tips and edges.

Humidity

Frangipani Plant grows best in humid conditions. To raise humidity, set the pot on a wet pebble tray or use a cool mist humidifier.

Clean the leaves by damp-wiping with a soft cloth to get rid of dust and also discourage pest infestations.

Fertilizer (Feeding)

Feed Frangipani Plant with aphosphorous-rich, water-soluble fertilizer every 4 weeks during the growing season to encourage flowering.

Stop feeding it during the cold season as growth is minimal at this time and feeding at this time can cause fertilizer burn and death of the plant.

Pruning

Prune Frangipani Plant by removing dead blooms and leaves to maintain the plant neat and also discourage pests and diseases.

Pinch off the growing tips to encourage growth of a bushy and compact plant.

Cutback the stems after flowering to 1/3 of their height to encourage new growth and keep the plant compact.

Repotting

Repot Frangipani Plant at the beginning of the growing season in a pot one size larger than the current one only when the plant becomes pot-bound as it blooms best when slightly root-bound.

The mature Red Jasmine plants can be top-dressed by replacing the top 3-4 inches of soil with fresh potting mixture.

Make sure that the pot has a drainage hole and the soil is free-draining soil to prevent it from getting soggy to avoid root-rot and eventual death of the plant.

Soil

The best soil for Frangipani Plant should be rich in organic matter and free-draining to prevent it from getting soggy while providing the required nutrients.

Propagation

Plumeria rubra (Frangipani Plant) propagation can be done at the beginning of the growing season from stem cuttings.

How to propagate Frangipani Plant from stem cuttings

Take stem cuttings of about 4-6 in. from a healthy Frangipani plant while ensuring each cutting has at least 2 leaf nodes.

Dip the lower cut end of the cutting in a rooting hormone to hasten rooting.

Insert the cutting in moist free-draining soil. Cover the set up with clear polythene to create a greenhouse effect in order to promote rooting of the cuttings.

Place the set up in a warm, brightly lit spot away from direct sunlight and allow the new plants to be well established before transplanting.

Gradually remove the polythene sheet over a period of two weeks to aclimatize the new Red Jasmine plants to the ordinary growing conditions.
