Mike - I have three different types of guems here in the Sacramento Valley. They all bloom in spring, with no real special care. I amended the soil when I first plant them, and then pretty much leave them alone. If I have extra fertilizer lying around, I may toss some on to the bed every couple of years. Here is the Blazing Sunset (left front) which is the most profuse bloomer. Photo was taken in June. I don't have the Totally Tangerine so have no clue what their bloom performance is.
