Forsythia: Spring's First Yellow Shout

Forsythia × intermedia

Forsythia explodes into pure yellow before most shrubs even break dormancy — the unofficial start of the garden season. Give it space to arch naturally; forcing it into a formal shape ruins the display.

Care & growing tips

Plant in full sun in any well-drained soil. Prune immediately after flowering — never in summer or fall. Remove a third of the oldest canes at the base each year to maintain vigor. Don't shear into a box — it flowers on arching branches.

FAQ

Frequently Asked Questions

01 When should I prune forsythia?

Immediately after flowering in spring — forsythia blooms on old wood, so summer or fall pruning removes next year's flowers. Remove 1/3 of the oldest canes at the base each year to keep it vigorous without ruining the natural arching form.

02 Why didn't my forsythia bloom this year?

Usually late frost killed the buds — forsythia flowers are vulnerable to spring freezes after warm spells. Also: too much shade or hard shearing. Plant where it has room to arch naturally; avoid turning it into a hedge.

03 Can I grow forsythia as a hedge?

You can, but you'll sacrifice bloom. Forsythia flowers on arching branches; shearing into a square shape removes most flowering wood. For hedging, use dwarf 'Gold Tide' which stays compact naturally and blooms on smaller branches.
