Hello dropofrain, when my Plumies are awake, I either add some compost or slow release fertilizer into the soil. We also go very, very dry and gets too hot here. Our growing conditions will be so different from areas with sustained heat, humidity and summer rains that Plumerias really enjoy.
So once I really know the Plumeria is awake, I start giving it good watering. Typically I can still get away with watering every three days if temps are just hovering in the 75F to 85F range. But once it starts hitting 90F and higher, and very dry with our dismal humidity, I do watering every other day. If forecast is 100F, it will be daily watering here. Just cannot catch up with the extreme dryness. I am thankful I do have city trees that provide some heat relief during the hottest time of the day, but once the triple digit days are here, it is just blanket heat all over, so got to help the plants find some relief from excessive dry heat stress.
