The Butterfly bush, like most plants, will benefit from a bit of pruning and cutting. However, there are several rules you should follow when reducing its size. If you’re asking, ‘do I cut back Butterfly Bush in the fall?’ then you’ll find the answer right here.
Most people assume that they should cut back their butterfly bushes in fall, but doing so can leave the plant vulnerable to plummeting temperatures and the subsequent cold when winter comes.
It’s best to wait until early spring to do some cutting, but only at the top of new growth.
When to Cut Back Butterfly Bush
The tough and gritty butterfly bush is a perennial plant in zones 5 through 9, but it can survive winters in zone 4. You can choose to leave it on the ground or dig it up, put it in a suitable container and bring it indoors (a process called overwintering).
For potted plants, it’s recommended that you bring them indoors and place them in a warmer location before the first frost arrives.
Butterfly bush owners tend to do a bit of autumn cleaning, which is perfectly fine. However, you should only limit this to removing dead leaves and stems or making it look neater.
Serious cutting back or heavy pruning should be reserved in mid-spring and when you see new leaves or stems emerging from old wood.
How to Prune a Butterfly Bush
Pruning your butterfly bush yearly is an important task as it can reach tall heights. Most landscapes prefer to see their shrubs in its entirety, including the blooms growing at the tip.
The good news is that you can cut back your butterfly bush freely, and it tends to grow right back and more vigorously than ever. They adapt to changes well and thrive as long as they’re in the right environment.
You can approach pruning butterfly bush with small cuts and only removing unwanted limbs to update its look. Others will want to cut it down to around two feet or so to keep it running wild and unruly.
If this is the case then you’ll want to watch out for new growth on the old wood and cut an inch or two above it so you won’t stifle the plant.
It’s recommended that you cut back your butterfly bush in spring and when you start to see new growth. In this case you won’t have to guess how far you have to go, and it will set up your shrub for maximum growth later on.
Another key thing to remember is patience- butterfly bushes tend to arrive late to the spring party and probably won’t show any signs of life until May or June.
You can observe the status of your plant until then, but don’t make cuts yet. It won’t have any detrimental effect if you choose to wait until summer as the plant is hardy enough to accommodate the pruning process.
Should You Deadhead a Butterfly Bush?
Deadheading is the process of removing spent flowers so the plant is encouraged to grow new ones. However, is this necessary for the prolific butterfly bush and its seemingly boundless energy to produce blooms?
You can add deadheading as a maintenance routine for butterfly bush whenever you decide to prune out unwanted branches and stems. It’s not really necessary since it does fine without it, but going the extra mile adds a touch of neatness to your landscape.
You can deadhead or prune to keep the shrub compact and flowering in its growing season, and you’ll be rewarded with bright-colored flowers that cover the plant. Fertilizing isn’t necessary if you add enough organic material to make the soil rich.
Adding a layer of mulch can be done right near the roots to protect it from the cold, but you must remember to water less in order to avoid root rot. This also provides the plant with nutrients and is more environmentally friendly than using fertilizer.
Do I Cut Back Butterfly Bush In The Fall: Conclusion
All in all, the butterfly bush is a hardy perennial shrub that can survive heavy cuts anytime during the year, but it’s best to leave it until mid- or late spring and when you see new growth emerging.
To increase its chances of thriving you should place it where it gets full sun and observe a regular watering schedule to keep the soil from completely drying out.
