Ditch that particular fertilizer (or use it on your annuals) and do your plumeria a favor and use a good, well balanced, timed-release fertilizer. Then you only need to do it a few times per season. Or if you purchase 'Excalibur' from Florida Colors, which was especially formulated for plumeria, you only need to use it once at the start of the season. I and others have had excellent results with this product. As a teaser here is a picture of cv. 'Guadalupe Fernandez' from earlier this year....
