Forsythia intermedia Complete Care-Guide

Forsythia Intermedia Background

The forsythia intermedia is part of the olive family (Oleaceae). The forsythia genus has 11 species containing dozens of varieties and cultivars.

This plant was named after the Scottish botanist, William Forsyth. He was the director of the Royal Garden at Kensington and a founding member of the Royal Horticultural Society.

Native Range

The forsythia intermedia is native to Asia, namely China and Japan. It has been naturalized in southeastern Europe and North America in the past few hundred years. 

Growing Habits

Forsythia intermedia is a deciduous shrub that grows six to ten feet tall with a spread of eight to twelve feet. It is a fast and vigorous grower. 

This shrub has rough brownish-grey bark and bears its flowers before its leaves. Because its stems grow naturally in an arching habit, it seldom needs to be pruned.

The forsythia intermedia does best in full sun and can tolerate some shade. If it receives too much shade, its stems will have a scraggly appearance and may not bloom as profusely.

This shrub is deer resistant and does not attract Japanese beetles.

USDA Hardiness Zones

Knowing your zone is important when selecting the right plant for your outdoor space. To figure out your zone, go to our home page and type in your zip code. There you will be shown exactly what zone you are in, no sign-up is required.

The forsythia intermedia can grow in zones five to eight. It can tolerate being grown in zone nine if given occasional shade and enough moisture.

This plant flowers in early spring before it grows leaves. The flower buds of the forsythia intermedia develop in fall and go dormant in winter. With enough warm days, forsythia intermedia will break dormancy and bloom. If the forsythia intermedia breaks dormancy but experiences a hard frost, the buds will die and the plant will not bloom that season.

Though forsythia intermedia are hardy, their tender buds may need protection from frost in late winter/early spring. This can be accomplished by covering the shrub with a woolen blanket or tarp.

Preferred Soil Conditions

Forsythia intermedia prefers a somewhat moist, free-draining soil. It can grow in soils that range from 6.0 to 8.0 pH. This shrub tolerates clay soils and can withstand alkaline soils. This shrub does not tolerate wet soil or excessive and prolonged periods of dryness.

Where to plant in the garden

This is a shrub that blooms for about two weeks in spring and shows off mellow, warm foliage colors in fall. It is an excellent shrub for beginning the momentum of succession planting. 

Succession planting is planting perennials, shrubs, and trees that vary in blooming times. This type of planting allows for there to always be something blooming or at its peak in the garden throughout the year. 

The forsythia intermedia can be grown in borders or hedges. It can fit in many gardening styles including spring gardens, Japanese gardens, and cottage gardens. 

How to Grow

Growing forsythia is as easy as planting any shrub. Here is the process step-by-step:

    1. Select a location that receives plenty of sun throughout the day
    2. Forsythia intermedia can be planted anywhere but at the bottom of a hill. This area is more prone to standing water and receives more frost in spring
    3. Dig a hole just big enough to cover the roots and not the stem
    4. If in a container, make sure roots are growing around in a circle, if they are, tease them apart so they can grow outward and not around
    5. Gently backfill and firm in soil with your hands
    6. Water thoroughly to help the plant establish and to remove any air pockets in the soil
    7. Do not prune for the first year or two so the roots can fully establish
    8. Fertilize each fall with 10-10-10 fertilizer

How to Prune 

  • Forsythia intermedia can be left to grow naturally
  • Broken or crossing branches should be removed to minimize disease potential
  • It can be lightly pruned by cutting back 20-30% of the branches at the base, this will thin it out and allow more light into the center
  • If very unruly or overgrown, it can be pruned within 3 to 4 inches of the ground, this can be done every four years to rejuvenate it

How to Propagate

Propagation can be done in two different ways: by layering or by cuttings.

Layering

This means taking one of its low-hanging branches to the ground without cutting or breaking it. The stem, in contact with the soil, will form roots. After several months or when there are enough roots, the branch can be cut away from the parent shrub. You can dig up the new plant or let it grow where it is.

Taking Cuttings

The second method of taking cuttings is very similar. Take a cutting of about six inches with the diameter of a pencil. Dip the cut end of the stem into rooting hormone if you have it, and insert it into a small container of potting soil. Water the plant regularly and plant once roots are visible, this may take up to a year.

It is a deciduous shrub widely appreciated for its abundant and vibrant yellow flowers that herald the arrival of spring. It offers numerous landscaping benefits, making it a popular choice for gardens and outdoor spaces. One of the primary advantages of incorporating it into landscaping is its early-blooming nature.  The Golden Color Forsythia Forsythia is unparalleled in filling yards with a profusion of golden colors. Their early-season blossoming is so abundant that it covers landscapes in a kaleidoscope of yellow hues, signaling the arrival of spring. Pollinators that emerge during the first signs of spring rely on the nectar produced by these blooms. Seeing these colorful, bell-shaped blossoms arranged so closely together along the stems is breathtaking. They can reach eight to ten feet in height and ten to 12 feet in width. Their bark is rough and gray-brown. They can be erect, rounded, mounded, or arching. Their branches can be straight or curved. You can plant them as focal pieces or in mass groups. Yellow To Purple Foliage With The Forsythia In addition to their showy yellow blossoms, they alter their leaves with the seasons. The leaves transition from green to yellow to purple depending on the time of year. They stay primarily green during the summer and transition from yellow to deep purple hues throughout late autumn, right before falling to the ground. These plants go dormant in the winter. They, particularly the more significant types, are shrubs that proliferate, often reaching a height of two feet in only 12 months. Because they grow fast, they can quickly fill empty spaces in gardens and landscaping. Their fast growth also makes them work well as natural privacy screens. You can even grow them as hedges and borders for gardens and driveways. Their rapid growth also increases their resilience to environmental stresses. Design a Border With Forsythia In addition to their use as natural hedges and borders, forsythias provide a great deal of creative flexibility in design. Planting them side by side along a garden path will cause them to grow inward, creating a natural archway. Some people use them to create focal points. Others use them to help with soil stabilization on sloped banks because of their deep, complex root systems that retain topsoil.
