Spirea, or spiraea, are popular perennial shrubs with pretty blooms in spring and summer. They're generally low-maintenance, but now and again, these plants benefit from a prune.
Spirea tend to get tangled and congested over time, which can spoil their good looks and increase the risks of disease. A good prune counteracts this as it opens up the structure, improving airflow and allowing more sunlight in, while giving the plants a tidier appearance. Pruning can also encourage new growth of foliage and flowers.
