spirea

For a Spirea, water regularly right after planting and then water deeply once a week during dry periods. During the growing season, water deeply and regularly once a week. When temperatures have cooled (usually beginning in mid-Autumn), then reduce watering to once every 2 weeks. It's best to water your Spirea early in the morning to allow for maximum absorption and to give the leaves time to dry off, preventing fungal diseases. In winter, water just enough to keep the soil from drying out.

Spirea thrives in full sunlight, meaning that it should receive at least 6 hours of direct sunlight each day in order to produce optimal bloom and growth. It is best to provide sunlight to the plant in the morning and early afternoon, as the intense afternoon sun could be damaging to the delicate foliage and flowers.

Spirea should be pruned in early spring before new growth begins. It's best to remove old and dead branches and shape up the bush to the desired size. Light to moderate pruning is recommended, as cutting away too much growth can ruin the shape of the plant and also reduce flowering the following season. It's best to cut off no more than 1 third of the total branches on the shrub.
