Japanese spirea

Japanese spirea should be watered deeply once or twice a week during the warmer months, allowing the soil to dry out considerably between waterings. Water should be applied to the soil near the base of the plant to avoid wetting the foliage, as this may promote fungal diseases. During long periods of extreme heat, you may need to water Japanese spirea weekly. Reduce the frequency of watering in the fall and winter months, as the plant requires less water during this time.

Japanese spirea (Spiraea japonica 'Goldflame') should receive full sun for 5-8 hours of direct sunlight daily. This sun should be at its peak during the mid-morning and late afternoon hours when the sun is not as intense and can provide the optimal amount of light without causing any harm to the plant. It's important to note that Japanese spirea do not do well in direct exposure to the sun's intense rays during the late afternoon and evening.

Prune Japanese spirea (Spiraea japonica 'Goldflame') in late winter (after the last frost) or early spring before it begins to produce new leaves. Prune to thin out the plant and remove any dead or diseased stems. Remove up to 1-third of the oldest growth and thin stems to open up the center of the plant. This will help maintain a compact and healthy shape of the plant.
