Propagate with cuttings. Can use greenwood cuttings in late spring or early summer, or semi-ripe cuttings in late summer. Put the branch in cold water for a couple of days, recut and put in warm water in sunlight. After the branch has soaked for a few weeks, the rootball should have expanded and it is ready for planting. It is best to replant when Forsythia is dormant.
For late winter or early spring indoor arangements, cut stems with many buds on a relatively warm day. Place in a bucket of warm water and recut the bottoms of the stems underwater. This will cause your cut Forsythia to bloom earlier than oudoors. Lots of sunlight and humidity will also help force blooming on cut stems.
Forsythia grows best in full sun or light shade and is frost hardy. Adequate.
Sub freezing temperatures in winter encourage flowering the following year.
Grow in average soil, adapting to a wide range of pH and urban insults. Soil must be well-draining. Keep watered during summer.
Feed lightly with Rose or All-purpose fertilizer in mid-February or mid-May.
After flowering, cut back flowered shoots to stronger lower shoots or buds. Established plants should be pruned more extensively; cut back old shoots to the base to promote new growth.
Root knot nematode. Forsythia is also prone to leaf spot, dieback, mosaic virus, and stem gall.
