Forsythia is one of the first plants to bloom in early spring, bursting with bright yellow flowers before the leaves even appear. It’s a tough, fast-growing shrub that grows well in most soil types and makes a cheerful addition to any garden. If you want more of this sunny plant, you can easily grow new ones from an existing bush. Propagating Forsythia saves money and gives you fresh new plants for borders, hedges, or sharing with friends.
There are several ways to propagate Forsythia, and each one is easy, even for beginners. You can grow Forsythia from stem cuttings, layering, or division. Below, we’ll go through each method step by step so you can decide which one works best for you.
Propagating Forsythia from Stem Cuttings
One of the most popular ways to propagate Forsythia is by taking stem cuttings. This method works best in late spring through early summer when the plant is actively growing.
Step 1: Choose Healthy Stems
Start by choosing a healthy, non-flowering stem from the current season’s growth. Look for one that’s about the width of a pencil and around 6 to 10 inches long. Make sure it’s green and flexible, not woody or dry.
Step 2: Cut and Prepare
Use clean, sharp pruning shears to cut the stem just below a leaf node. Then, remove the leaves from the bottom half of the cutting. If there are any flower buds, pinch them off too. You want the plant’s energy to go into forming roots, not flowers.
Step 3: Rooting Medium
Next, prepare a pot filled with a mix of half perlite and half peat moss or use a commercial seed-starting mix. Dampen the mix slightly but don’t soak it.
Step 4: Plant and Cover
Dip the cut end of the stem into rooting hormone to help it root faster, then stick the cutting about halfway into the soil mix. Firm the soil around it so it stands upright. Cover the pot with a clear plastic bag or place it in a mini greenhouse to hold in moisture.
Step 5: Wait and Watch
Place the pot in a warm, bright spot but out of direct sunlight. Keep the soil moist but not soggy. In about 4 to 6 weeks, the cutting will develop roots. You’ll know it has rooted when you see new leaves starting to grow.
Once the roots are strong, transplant the new Forsythia into a bigger pot or directly into the garden.
Propagating Forsythia by Layering
Another simple way to propagate Forsythia is by layering. This method works well in spring or early summer when branches are flexible. Unlike cuttings, you don’t remove the branch from the mother plant. Instead, you pin it down and let it grow roots while still attached.
Step 1: Choose a Low Branch
Find a healthy, flexible stem that grows close to the ground. It should be at least a foot long so you can bend it down easily.
Step 2: Wound the Branch
To help the branch root faster, scrape a small area of the bark from the underside of the stem, about 6 inches from the tip. You can use a knife or pruning shears to gently scratch it. Don’t cut too deep.
Step 3: Bury and Secure
Dig a small trench in the soil under the scraped area. Then, bend the stem down so the wounded part rests in the trench. Cover that section with soil and pin it in place using a small rock, a piece of bent wire, or a garden staple. Leave the tip of the stem sticking out of the soil.
Step 4: Care and Wait
Water the buried section regularly to keep the soil damp. Over the next few weeks, roots will begin to form where you scraped the bark. You’ll know it has rooted when you see new shoots or leaves on the tip.
After about 6 to 8 weeks, cut the stem from the main plant and transplant the new rooted section to another spot in the garden.
Propagating Forsythia by Division
Although not as common as cuttings or layering, dividing Forsythia is another option. This works best in early spring or fall when the plant is dormant or just starting to grow.
Step 1: Dig Up the Plant
Choose a mature Forsythia shrub that has multiple stems and a good root system. Carefully dig up the entire plant, making sure to keep as much of the root ball intact as possible.
Step 2: Divide the Roots
Use a sharp spade or knife to divide the root ball into two or more sections. Each section should have at least one strong stem and a healthy chunk of roots. Try not to break or tear the roots too much.
Step 3: Replant
Dig a hole in the new location that’s wide and deep enough to hold the divided root ball. Place the division in the hole, backfill with soil, and water well. Keep the soil moist for the first few weeks as the plant settles into its new spot.
This method works well if you want to move an old Forsythia or if you’re redoing a garden bed and need smaller shrubs to space out.
Which Method Should You Choose?
All three propagation methods work well, but each one has its benefits. If you want quick results and have a mature plant, layering is a great choice. It requires very little work and roots naturally. If you have time and want more control, try stem cuttings. You can take several at once and grow multiple plants. Division is best if you’re already moving a plant or want to split a large shrub into smaller ones.
Tips for Success
To get the best results when propagating Forsythia, follow these tips:
- Always use clean, sharp tools to avoid spreading disease.
- Choose healthy, disease-free parent plants.
- Water regularly, especially during the early rooting stages.
- Avoid full sun for new cuttings or layered branches until roots form.
- Add mulch around new transplants to hold in moisture and reduce weeds.
When to Plant Your New Forsythia
Once your new Forsythia has developed roots and is ready to plant, choose a sunny spot in the garden. Forsythia loves full sun and well-drained soil. Although it tolerates partial shade, it blooms best with at least six hours of sunlight each day.
Plant it in early fall or early spring so it has time to establish roots before extreme weather sets in. Water regularly until you see strong growth, then switch to watering during dry spells only. With a little care, your new Forsythia plants will bloom beautifully year after year.
Final Thoughts
Forsythia is one of the easiest shrubs to propagate, and with so many methods to choose from, you can grow more plants without spending extra money. Whether you use cuttings, layering, or division, you’ll enjoy the bright yellow flowers and fast-growing nature of this cheerful shrub. Pick the method that fits your garden goals and enjoy watching your Forsythia grow and spread with each new season.
