watering

Border forsythia should be watered deeply once a week, to a depth of 8-12 inches. During periods of extreme heat, it may be necessary to increase the frequency of watering to twice per week. Water thoroughly, allowing water to penetrate to the root system at the base of the plant. Avoid wetting the foliage during the watering process, as this can attract fungal disease. Soil should be allowed to dry out between waterings.

sunlight

Border forsythia (Forsythia intermedia 'Sunrise') should be grown in full sun, meaning at least 6 hours of direct sunlight each day, to ensure good flowering. This plant species can tolerate partial shade during the afternoon, however it should be provided with at least 4 hours of direct sunlight daily in order to promote healthy growth. Although this plant species is quite tolerant of full sun, it may be at risk for damage in extremely hot climates, so it is important to provide some protection in such conditions.

pruning

When pruning a border forsythia (Forsythia intermedia 'Sunrise') it should be done annually in the late winter or very early spring, when the plant is still dormant. Pruning at this time will ensure maximum flowering during the spring. This shrub should be pruned only after it has flowered, as cutting the stems before it flowers will shorten its bloom period. When pruning, cuts should be made on a slight angle roughly 1-third of the way into the previous year's growth. Regular pruning will help keep the shrub looking neat and encourage more prolific flowering.
