I'm new to adeniums and have 12 of them, some are blooming and some 6 mo to 2 yrs, and bought a 10 yr old 1.5 ' by 1.5' just recently so I've been reading forums as much as I could to take care of all my babies. Is it better to just use a time release fertilizer than the Dyna Gro liquid ones, for growth, and for bloom?
