Expert Response
We suspect that your spirea may be getting too much moisture from rain and watering.
Never water overhead, i.e. sprinkling or hosing from above. Apply water to the soil at the base of the plant.
Most plants grow well with about 1" of water a week. Supplement rainfall by watering your spirea only when at least the top 1/2 to 1 inch of soil has dried out.
Also, brush off loose leaves and remove dead leaves.
