Forsythia Bush Growing Tips
When a forsythia bush blooms, it’s a sure sign that warmer weather is on the way. Forsythia is one of the earliest bushes to bloom in spring, making its bell-shaped golden flowers a welcome sight.
Forsythia is a fast-growing, large shrub that thrives in Zones 4-8. Here’s how to find your plant zone. It will grow to be 8 to 10 feet high, though there are dwarf varieties available and it can be pruned for size. Give this plant a try as a hedge that’ll put on a spectacular show in the spring.
For best results, grow forsythia in well-drained soil with regular moisture and in full sun to part shade.
Forsythia can bloom as early as late January or early February in warmer zones. It’ll bloom through late March in colder zones. The sunny yellow blooms last for 10 to 14 days. After the flowers fade, dark green leaves emerge.
Blooms develop in late summer and early fall for the following year, so the shrub should be pruned immediately after flowering in the spring for best results.

Why Is My Forsythia Bush Not Blooming?
“My forsythia had flowers for the past two years, but only on the bottom of the shrub. What’s wrong with it?” asks Janet Grosse of Madison, Wisconsin.
Gardening expert Melinda Myers weighs in: “This is a common problem for those of us growing forsythia in colder climates. Even though the plant tolerates the winter cold, the dormant flower buds that form during the previous summer are often killed.”
Melinda has recommendations for cold-hardy cultivars that’ll thrive in areas with more intense winters: “In the future, select forsythia cultivars, such as Northern Sun, Show Off Starlet, Gold Cluster or Fiesta. They all have hardy flower buds that can withstand colder weather.”
You can try other cultivars to fit your needs, too. Northern Gold is an upright grower and Meadowlark is fast-growing with an arching form. For a cultivar that’ll thrive in warmer climates, opt for Spring Glory.
