I am no gardening expert, but I love plants, flowers, dirt and watching the garden grow. I currently have 11 spirea planted in various locations in gardens around my home. Anthony Waterer, Neon Flash, Princess Spirea and Bridal Wreath Spirea are what I chose to plant and all are thriving. 7 Spirea receive morning sun ,( by 2 p.m. are completely shaded) 1 receives partial sun, and 3 receive hot afternoon sun (morning shade until 1:30pm). Every year I add compost and new mulch around these plants. In the Fall or early Spring I cut back ( prune hard) the Anthony Waterer and Neon Flash Spirea, leaving 3 to 4 inches. Every Spring they grow with such vigorous growth. If your spirea are dying, I would try moving them to another location in the garden. Then perhaps add new soil mixed with compost and top with a couple inches of mulch. Sometimes gardening is learning by trial and error, not being afraid to move plants around the garden until you find a place they thrive. Sometimes we need to cut away a good portion of the plant to trigger new growth. I also find gardening books from the library very helpful. Many of my neighbours love to garden, so sometimes I ask them about a particular plant, because they probably have experienced similar problems and may have needed solutions. I hope some of this information will be helpful. Ever Learning, Zone 5

Spirea
As most varieties of Spirea are hardy in the UK I would assume the problem in Florida would be too much heat so watch the water.
In order to tell if a Spirea shrub is dead, the branches must be thoroughly looked at. If they are brown, brittle, and fall right out when touched, then the bush is probably dead.
Under-watering or over-watering can cause Spirea to have a lot of dead branches.ÊWater can fail to penetrate deep into the soil Êor it can penetrate excessively;driving out oxygen.Ê
Once a year unless pruned.
