Plumeria can tolerate coastal conditions to some extent, but excessive salt exposure can damage the plant. If you live in a coastal area, provide some protection from direct salt spray and strong winds. Rinse the leaves and stems with fresh water occasionally to wash off accumulated salt. Growing Plumeria in containers and bringing it indoors during severe weather can also help protect it from salt exposure. Monitor the plant for signs of salt damage, such as leaf burn or yellowing, and adjust its placement or care accordingly.
