Butterfly bushes, or Buddleia spp., are well-known flowering shrubs with cone-shaped flowers that hummingbirds and butterflies love. They can grow quickly and adapt to a wide range of climates, but you may need to move an existing butterfly bush to a new spot if it gets too crowded, doesn’t get enough sunlight, or just looks better there. When should I move a butterfly bush? Timing is very important, so when is the best time?
Why Transplant a Butterfly Bush
Here are some common reasons for transplanting a butterfly bush
-
It’s crowding out other plants or encroaching on a walkway. Butterfly bushes can grow quite large, up to 10 feet tall and wide.
-
The current location doesn’t get enough sun. Butterfly bushes thrive in full sun locations. Insufficient sunlight will reduce flowering.
-
Improving the landscape design. You may want to reposition the butterfly bush to create a better overall look.
-
Poor drainage leads to root rot. Butterfly bushes need well-draining soil. Wet sites can be problematic.
-
To propagate new plants. Transplanting suckers that emerge from the roots is an easy propagation method.
When to Transplant Butterfly Bushes
Butterfly bushes are hardy, but timing is crucial for transplant success:
Spring
In most places, planting should happen between early and mid-spring. This gives the bush time to grow roots before the heat of summer. Right when the plant wakes up from its winter sleep and new growth starts to show is the best time.
Fall
Fall transplanting can work in mild winter climates after the plant goes dormant. However, the roots are more vulnerable to winter damage.
Avoid Summer
Summer transplanting is risky because butterfly bushes have depleted energy reserves. The heat also stresses the roots. Wait until spring or fall instead.
Transplanting Process
Follow these steps for transplanting butterfly bushes:
Select a Site
Choose a site with full sun and well-draining soil. Amend clay soils with compost to improve drainage.
Prune the Shrub
Cut back the butterfly bush a lot, leaving only 6 to 18 inches of stem. This reduces transpiration demands and encourages new root growth.
Dig Around Roots
Use a spade to score a circle around the shrub about 2 feet out from the trunk to sever the outer roots.
Prepare New Hole
Dig a hole in the new site about twice as wide as the root ball. Scrape the sides to loosen compacted soil.
Lift and Transplant
Carefully lift out the shrub using the spade as lever, keeping as much of the root ball intact as possible. Place it in the new hole.
Backfill and Water
Refill the hole with native soil, water thoroughly, and apply mulch. Stake tall plants if needed.
Post-Care
Water regularly for the first month and resume normal care. Prune any dead stems in spring. Blooming may be reduced the first year as the plant re-establishes.
Tips for Transplanting Butterfly Bushes
Follow these tips to ensure success:
-
Water the plant deeply a few days before digging it up.
-
Move the plant as quickly as possible once lifted to prevent root drying.
-
Prune off any damaged roots before replanting.
-
Set the root ball at the same level it was originally growing.
-
Water frequently after transplanting until new roots establish.
Butterfly bushes can be readily transplanted if done at the right time of year – early to mid spring is best in most climates. Proper site preparation, attentive digging and replanting, and good follow-up care will help ensure your transplanted butterfly bush re-establishes quickly. With a little TLC, you can successfully reposition butterfly bushes to keep your landscape looking its best.
When is a Good Time to Transplant?
Experts agree that fall is one of the best times for transplanting, but spring is also considered good. Each season has advantages that the other lacks. Many claim that fall is the best time to transplant trees and shrubs.
Fall transplants can benefit from the months of cooler, moister weather ahead. Thanks to autumn rains, the plant’s roots get a chance to grow before summer’s heat dries up the earth. Strong roots anchor a new transplant into its new location and help stock up on needed nutrients.
Compare this to spring planted trees that will have few roots out into the yard when the summer heat arrives so soon after planting. You’ll certainly have to irrigate early and often with spring planting.
Others, though, say that spring is the best time to move trees and shrubs because the new plants won’t have to deal with winter right away. Trees transplanted in fall must face winter winds and cold temperatures before they get settled in their new location.
When to Move Perennials?
The key to moving perennials is not to choose a bad time. You should never move perennials when they are in flower. Wait at least a few weeks after a plant flowers to pick up the shovel. One rule of thumb is to transplant fall-blooming perennials in spring and spring flowering perennials in fall.
How to Transplant a Butterfly Bush
FAQ
Can you dig up and replant a butterfly bush?
Transplanting butterfly bushes is easy. They are hardier than many other shrubs. I moved two in early summer, but early to late spring is better, I thinned the bottom growth and the top for easier transport, Dug up as much of the rootball as I could handle myself, then put them in their new home.
What time of year do you cut back butterfly bushes?
-
Why late winter/early spring?Butterfly bushes bloom on new growth, so pruning them in late winter/early spring before new growth starts ensures that the bush will produce plenty of flowers.
-
Avoid pruning in the fall:While some pruning can be done in the fall in warmer climates to tidy up the plant, it’s generally best to avoid significant pruning in the fall, especially in colder climates, as it can leave the bush more vulnerable to winter damage.
-
Wait for new growth:Don’t prune until you see signs of new growth, like green buds on the stems.
-
How to prune:Cut back the bush to about 12-24 inches (or even to the ground for more vigorous growth), and remove any dead or broken branches. Make sure to cut just above a bud to encourage new growth.
Do butterfly bushes have deep roots?
- Root Depth and Spread: Butterfly bushes, especially the purple butterfly bush, have roots that can go down 3 to 6 feet, and spread out 2 to 3 feet horizontally.
- Soil Impact: The depth of the roots can vary depending on the soil conditions, with well-drained soils encouraging deeper growth.
- Root Health: Healthy roots are typically firm and white or light tan.
- Care Implications: Understanding the root system helps with proper watering, as deep and widespread roots can access moisture from deeper soil layers, according to Greg App.
- Watering: Deep watering is essential to encourage robust taproot development, according to Greg App.
- Nutrient Uptake: The horizontal spread of roots is crucial for nutrient absorption.
- Removal: Butterfly bushes are relatively easy to remove because they don’t have very dense, deep root systems, according to Black Gold.
What is the lifespan of a butterfly bush?
The average life expectancy of a butterfly bush is 10-20 years. Consequently, once older bushes begin producing fewer flowers, it is time to consider replacing them.
What time of year should you avoid transplanting a butterfly bush?
During the hot summer months, don’t move plants because they might not be able to handle the stress of being moved. As the plant goes to sleep in early spring or late fall, these are the best times to move a butterfly bush.
When should you plant a butterfly bush?
Timing is like picking the right dance partner at a party—critical and rewarding! Transplanting a butterfly bush is best done during early spring or late fall. These times allow the bush to focus on root development instead of worrying about all that glamorous top growth. When? Spring might personally be my favorite season.
Is it recommended to transplant a butterfly bush?
Yes, it is recommended to transplant a butterfly bush. The best time to do so is during the dormant season, which is late fall to early spring. This allows the plant to adjust to its new surroundings before the active growing season begins.
What is the best season to transplant a butterfly bush?
Spring might personally be my favorite season. This is when plants start waking up, so the butterfly bush is more likely to adapt well. The cool climate eases the transplant shock, much like jumping into a refreshing pool on a hot day. Fall, on the other hand, isn’t just about pumpkin spice lattes and cozy sweaters.
Should you water a butterfly bush before transplanting?
After pruning, water the butterfly bush thoroughly a day or two before transplanting. This will help loosen the soil around the roots and make it easier to dig up the plant. Watering also ensures that the plant is well-hydrated before the transplant, reducing the risk of shock.
Should you prune a butterfly bush after transplanting?
It also adds nutrients to the soil as it breaks down over time. Pruning is an essential part of maintaining a healthy butterfly bush. After transplanting, it is recommended to prune the plant back by about one-third. This will help reduce stress on the plant and encourage new growth.
