BouGain 6-8-10 Plus Minors specifically lists it is for bougainvilleas, but if the nutrients your plants need match the ones it contains it should be ok to use on them as well. For complete information we would recommend contacting the manufacturer directly. BGI can be reached at (561) 374-9216.
BouGain 6-8-10 is a fertilizer geared towards use on Bougainvillea, however since it contains no harsh ingredients it could be safely used on Desert Rose for fertilization if the nutrients it provides are what other plants need.
