watering
Iberian spirea (Spiraea hypericifolia) will need regular watering to thrive. Water the plants whenever the top 2-3 inches of soil feels dry to the touch. Usually, this means that you will need to water these shrubs once to twice a week during the growing season (April to September). In the fall and winter months, you can reduce the frequency of watering, but do not let the soil dry out completely. Avoid over-watering as this could lead to root rot, and provide good drainage to prevent saturation.
sunlight
Iberian Spirea (Spiraea hypericifolia) prefers full sunlight throughout the day and tolerates partial shade, with at least 6 hours of full sun a day being ideal. The best time of day for your Spirea to receive sunlight is during the morning, as this will allow the plant to effectively photosynthesize sunlight that is needed for its growth and health. Avoid direct sunlight, such as full middle-of-the-day sunlight, as this can be damaging and may lead to undesirable results, such as wilting or scorched foliage in extreme cases. Too much shade can also stunt the growth of your Spirea, so plant it in an area that receives ample sunlight throughout the day.
pruning
The Iberian spirea (Spiraea hypericifolia) should be pruned each spring just after the plants have finished flowering. Pruning is best done by removing a third of the oldest and longest branches to encourage new growth. Dead or diseased branches should also be removed, and those that are suckering should also be trimmed back. Pruning will ultimately shape and keep this plant compact, while also removing any old flowers that turn brown and die off. Always make sure to use clean, sharp pruning shears when pruning your Iberian spirea.
