Plumeria care for the most part is minimal. They are easy to grow, can withstand all kinds of temperatures and are not fragile. They are mainly meant for outdoors, where they can be grown in containers as well as on ground. They grow well in summers and are dormant during the winters when they often shed all their leaves.
Plumerias need at least 5 hours of direct sun in a day. Keep soil moist during the summers but water sparingly during the winters. You should water the plumeria deeply and make sure it is dry before watering it again. Generally you can water it twice a week during summers.
Not enough water or too much water can lead to the leaves turning yellow. Because they need regular, even amounts of water, dry spells can cause plumeria leaves to turn yellow and cause them to drop off the plant, with the bottom leaves suffering first. If you see yellowing leaves, check the soil by digging down several inches making sure it isn't wet.
Plumerias can be pruned in later winter or early summer before the new growth starts.
