It’s no secret that nutsedge is one of the most tenacious perennial weeds around. It’s tremendously quick to spread and equally difficult to control. Hence, it’s safe to say that the last thing any garden-proud being wants is for it to pop up in their beloved flower beds. Sadly, it happens.
But try not to worry! Getting rid of it may not be a breeze, but it’s certainly possible.
Below, I’ve outlined several methods you may want to look into, as well as key considerations to be aware of along the way. Happy learning!
So, how do you get rid of nutsedge in flower beds? From digging it out to tackling it with a traditional herbicide, there are plenty of approaches you may want to look into to remove nutsedge from a flower bed.
For ease, I’ve outlined them below for you. Go ahead and take your pick!
Why Have I Got Nutsedge Growing In My Flower Beds?
Nutsedge thrives particularly well in environments that are rife with moisture. Thus, its emergence in your flower bed is likely due to one of the following causes: a particularly wet season, poor soil drainage, or accidental overwatering of the flower bed.
To make matters worse, they grow in dry conditions too.
Regardless of what has caused them to emerge, their presence is not to be taken lightly.
They spread at an alarming rate, reproducing both through seeds as well as their complex rhizome system that lies beneath the surface.
How To Effectively Remove Nutsedge From A Flower Bed
Thankfully, there is hope on the horizon.
Below, I’ve shared the most effective methods to remove nutsedge from your flower bed.
First, regardless of which of the following methods you opt for, undertaking them with care is a big must.
That is if you want to keep your flower bed healthy and intact.
The more accurate and thoughtful you are during the removal process, the less likely you are to inflict damage onto your surrounding plants.
Dig Them Out
If you’re partial to a laborious effort from time to time, it might be a good idea to dig the nutsedge out manually.
It may be physical labor, but for many, the hands-on aspects that gardening has to offer are the most fun and fulfilling of them all.
Use a handheld digging tool to help you out, and proceed to dig deep enough to entirely remove the nutsedge’s root system – tubers included.
A thorough job is the key to preventing a reemergence.
If you’d rather not get your hands too dirty, vinegar could be the ideal solution for you.
Simply combine around a cup of white vinegar with a splash of dish soap and a gallon or so of water.
Spray the solution over the nutsedge to dry it out and, ultimately, kill it.
It’s worth noting that the end-to-end process may take a few weeks, if not longer. Be prepared to conduct multiple resprays.
Bleach is, of course, one of the most highly chemical solutions of the bunch.
For this reason, many gardeners wouldn’t consider it. But if you’re open to it, the best practice is to dilute it with water before spraying it onto the nutsedge.
Once combined, ensure that your bottle is set to a streamlined spray as opposed to a mist and spray away.
It’s worth noting that even if you’re as accurate as you can humanly be, there is still a chance that you may accidentally spray your surrounding plants.
In this case, prepare yourself for the worst.
Bleach has a rightful reputation for its unforgiving nature, and while it may be powerful and, thus, effective, it poses an unquestionable environmental risk.
Instead, why not pop to your local garden store (or get some on Amazon here) and pick up a bottle of traditional weed killer?
There are several products on the market that specifically target nutsedge, some of which are even organic! For best results, follow the instructions on the bottle.
Again, brace yourself for an effort that may span several weeks.
By applying a thick layer of mulch over the nutsedge, you’ll prevent it from absorbing sunlight and simultaneously suffocate it.
However, as previously mentioned, its root system is pretty complex, and whilst you may cover what you can see, this surface-level approach won’t prevent nutsedge stems from popping up in other locations across your flower bed.
How Long Does It Take To Remove Nutsedge from a Flower Bed?
Typically, it takes at least a few weeks to remove nutsedge from a flower bed.
Nutsedge is sturdy and persistent and has long proven to be quite the challenge.
The exception is if you opt to dig it out. Then, provided you remove every single trace of it, it’ll be gone on the spot.
Things To Consider When Removing Nutsedge From A Flower Bed
Nutsedge reproduces rapidly, so when you first spot it, take action as soon as possible!
By working quickly, you’ll save yourself from dealing with a much trickier nutsedge presence down the line.
By looking after your flower bed and feeding it with fertilizer, your plants and flowers will bloom to the best of their ability.
Nutsedge is far less likely to pop up in a full flower bed than one that seems to have sufficient space for it.
Ensure your flower bed has well-draining soil and that it doesn’t get too wet for extended periods.
Whilst nutsedge grows in a variety of conditions; it especially thrives in moist ones. Remove as much excess moisture as you can.
Additionally, nutsedge doesn’t grow well in shaded areas.
If your flower bed is already in the shade at no expense to the plant life within it, there’s no need to take action.
However, if it gets significant sun that it doesn’t necessarily need, you may want to look into relocating it.
It’s quite the task and one that requires a meticulous approach, but if it can prevent the growth of nutsedge, it’s probably worth it!
