All About Forsythia Bushes

Also known as Golden Bell, this deciduous shrub is one of the first to bloom in the spring with elegant yellow, four-petalled flowers all along (nearly) the entire stems! Forsythia is a lovely native of Asia and named after William Forysth, one of the founders of the Royal Horticultural Society in Great Britain. Actually a member of the Olive family, Forsythia does have 'fruit' but in the form of a capsule.

Forsythia feature very attractive flowering branches that are liberally covered the entire length with incandescent flowers on an easy-care and low-maintenance shrub! The Forsythia flower blooms before its leaves appear, making the plant even more spectacular. The long slender green leaves are slightly toothed along their margins and look great all growing season. Many new varieties have fantastic fall color too!

Troubleshooting

There are a variety of reasons why a particular plant might not bloom. One reason your plant might not bloom well is that it received too much shade and not enough sun.

Another reason could be that your plant was given too much lawn fertilizer, which results in beautiful foliage, but a lack of flowers. It’s important to know that if the plants are pruned too long after bloom, it will eliminate the flower buds on that older wood! Always only prune right after the flowers finish.

Pruning Your Forsythia Shrubs

We recommend that you give Forsythia plenty of space to reach its full glory. Doing so will eliminate annual pruning for size control. In addition, you'll love the graceful, arched form that a natural Forsythia bush exhibits.

While these rugged plants handle pruning like champs, wouldn't you rather do a small job every other year rather than a big task every year?

However, if you do wish to prune your flowering shrub, know that these flowering ornamentals bloom on old wood. Wait to control them by pruning directly after they bloom. Let your Forsythia bloom abundantly for weeks and as soon as the flowering is done you can begin to prune. You can even cut it all the way to the ground and allow all new branches to develop fresh flower buds for the next year.

Blooms on Old Wood
Prune Immediately After Flowering
Renewal Prune Every 3 - 5 Years

Regular pruning creates a bushier growth habit and more flowering! Every few years, rejuvenate your Forsythia bush by removing a few of the oldest, thickest stems at ground level. Reach down into your shrub to find crossing or otherwise damaged branches, and cut a long length off.

Forcing Flowering Stems For Winter

Force Forsythia stems by cutting a few stems from the interior of your shrub in late winter or early spring. These trimmings can be forced indoors and make great spring container accents and indoor floral bouquets! These stems need to go through a winter so they are exposed to enough chill hours to stimulate bloom, both on the shrub and when cut for forcing.

As soon as cut, plunge the ends into the water, the ends cut at a 45-degree angle. Bring them indoors in a warm room in a tall vase of warm water and enjoy the Forsythia flowers, which open over a few days.

Force Forsythia stems with the kids, and pair well with other flowering shrubs like Pussy Willow, Redbud, Flowering Dogwood trees, Serviceberry, Flowering Quince, Magnolias, and Crabapple trees too! You'll all love these gorgeous indoor arrangements! Mix and mingle with the flowers of your spring bulbs and ephemerals for a gorgeous show!

Frequently Asked Questions

When to prune forsythia?

Prune forsythia immediately after flowering ends in late spring, typically May through early June. Forsythia blooms on old wood, so pruning later in summer or fall will remove next year's flower buds. Remove up to one-third of the oldest canes at ground level annually to maintain vigorous growth and abundant blooms. For overgrown shrubs, you can cut the entire plant back to 6-12 inches above ground for complete rejuvenation.

How to prune forsythia bushes?

Prune forsythia bushes immediately after flowering in late spring, as they bloom on old wood and set next year's buds by midsummer. Remove up to one-third of the oldest canes at ground level annually to encourage new growth, and lightly trim wayward branches to maintain shape. Avoid fall or winter pruning, which will eliminate spring blooms. For best results, use clean, sharp pruning shears and focus on opening the center for better air circulation.

What USDA hardiness zones are best for forsythia shrubs?

Forsythia shrubs thrive in USDA hardiness zones 3-9, making them adaptable to most temperate climates across the United States. These cold-hardy shrubs can withstand winter temperatures down to -40°F in zone 3, while also tolerating the heat of southern zone 9 regions. Some varieties like Border Forsythia are particularly hardy and reliable in zones 4-8. Choose a variety suited to your specific zone and plant in fall or early spring for best establishment.

Can you trim forsythia in the winter?

Winter pruning is not recommended for forsythia shrubs because you'll remove the flower buds that have already formed for spring blooming. Forsythia sets its buds in late summer and fall, so any winter trimming will significantly reduce or eliminate the spectacular golden flower display. The optimal pruning window is immediately after flowering ends in late spring, typically May through early June. Wait until after the blooms fade to ensure maximum flowering potential for the following year.

How often should you water newly planted forsythia?

Newly planted forsythia requires deep watering 2-3 times per week for the first growing season, providing about 1 inch of water each time. In zones 3-9, water early morning to allow foliage to dry before evening and reduce disease risk. Once established after the first year, forsythia becomes quite drought tolerant and needs supplemental watering only during extended dry periods. Check soil moisture by inserting your finger 2-3 inches deep and water when the top layer feels dry but not completely parched.

Can you keep forsythia small?

Yes, you can keep forsythia compact through proper pruning and variety selection. Compact cultivars like Show Off® and Gold Tide Forsythia naturally stay smaller than traditional varieties, typically reaching 3-4 feet instead of 8-10 feet. Prune immediately after blooming in late spring to control size, as forsythia sets next year's flower buds in summer. Choose dwarf varieties for long-term success rather than constantly pruning larger cultivars.

Can i prune forsythia in winter?

Winter pruning is not recommended for forsythia shrubs because they set their flower buds in late summer and fall for the following spring's bloom. Pruning during winter months will remove these pre-formed buds, resulting in little to no flowering. The optimal pruning window is immediately after the flowers fade in late spring, typically May through early June. Wait until after the golden blooms finish to ensure maximum flower display the following year.

What type of soil does forsythia prefer for healthy growth?

Forsythia thrives in well-draining soil with a pH between 6.0 and 8.0, tolerating both slightly acidic and alkaline conditions. These hardy shrubs adapt to various soil types including clay, loam, and sandy soils, but they perform best when drainage prevents waterlogged roots. Forsythia grows successfully in USDA zones 3-9 and tolerates drought once established, though consistent moisture during the first growing season promotes strong root development. Amend heavy clay soils with compost before planting and ensure your planting site receives at least 6 hours of direct sunlight daily for optimal flowering.

Does forsythia bloom on old wood?

Yes, forsythia blooms exclusively on old wood from the previous year's growth. The flower buds form during summer and fall on mature stems, then open in early spring before the leaves emerge. This means any pruning should be done immediately after flowering ends in late spring to avoid removing next year's blooms. Prune forsythia within 2-3 weeks of bloom completion to maintain maximum flowering potential.

Do you prune forsythia?

Yes, you should prune forsythia regularly to maintain their shape and flowering performance. Prune immediately after blooming finishes in late spring, as forsythia sets next year's flower buds on new growth during summer. Remove about one-third of the oldest canes annually and trim back overgrown branches to maintain the shrub's natural arching form. Wait until after the golden blooms fade to ensure you don't sacrifice next spring's flower display.
