Use the first nice days of the season for a spring garden clean up for your flower beds! See the before and afters plus get tips for cutting back, weeding, and keeping the weeds down all season so you can enjoy the flowers.

If you're a gardener getting the garden beds cleaned up and ready for the new season is always a goal in late winter and early spring.
So you can probably relate when I say that it feels good to have two garden tasks accomplished by the second weekend of March:
- The vegetable garden awakened for the spring by mulching the asparagus, pruning fruit trees and bushes, cleaning up dead plants, and getting two beds mulched and ready for pea and spinach planting.
- A flower bed close to the house cleaned up and weeded.
I shared about prepping the vegetable beds here, so I thought I'd share some tips and techniques for spring cleaning your flower beds, too.
Why? Because if you get to them as soon as you can, they can be almost weed free for the rest of the season. Really!
We'll use the shrub and perennial bed you can see in the photo above for the example. It's all nice and tidy there, but here's how it started out that morning:
Yep, same bed I promise. Brown stalks from the previous year mingling with the new spring growth that is already pretty full.
Along with weeds, of course. Oh, well - it makes it easier to see what needs to be done, doesn't it?
Why clean up the garden in spring
I'm a spring cleaner-upper vs. a fall one for a number of reasons:
- In the fall I'm usually too busy with preserving the harvest to attempt any clean up.
- Most plants survive winter better with the cover of the previous season.
- Birds eat the seeds of the dried flowers.
- And roses and plants need spring pruning anyway.
Plus, where I live in the western Oregon valley most things in the garden still look good through October.
So the motivation is not there to do anything until November and well, it's all about the holidays come November, isn't it?
Spring Garden Clean Up
This shrub and perennial bed is about 6 x 20 feet, planted with a few evergreen shrubs, roses, and perennials.
It took about one and a half hours to go from the before state you see above to the after:
Here's how to tackle a spring garden clean up like this:
- Start with the tallest, most overgrown plants first. In this case, the roses and clematis. I cut all of them down to about 2-3 feet. The roses are shrub varieties and we have such a problem with black spot here that I find it's best just to cut the roses back hard. They flower later, but tend to be much healthier (at least in the beginning of the season). These clematis grow many feet every year, so I cut them back to keep them sized for the trellises.
- Prune evergreens if needed. Pruning and shaping will be easiest now, before the perennials grow bigger and make reaching the evergreens more difficult. The only shrubs I shape are the boxwoods here to keep them sized for the bed.
- Pull weeds and cut off any dead plant parts. Start on one side of the bed and move to the other side.
- Prune and/or cut back any existing perennials (see specific examples below).
- Edge the bed, if needed. If it's a grass border, it will always be needed. At least if you live in the Pacific NW.
- Lay down newspaper and cover with a mulch of compost or bark. This is my not-so-secret secret to a weed-free flower border (I've been telling you guys for years...). Please do this if you haven't - I promise it will make your life SO much easier!
TIP: Watch the video on easy organic weed control with paper and mulch here for more details.
Here's the thing - if you do all these steps as early as you can in spring, you will not have much to do in a bed like this for the entire growing season. Trimming a few plants and pulling a weed or two is about it.
Seriously.
However...if you get to step 5 and don't have compost or time to lay the paper and mulch and wait for 1-2 more months, you will have to weed all over again because they will be too out of control to even cover with the paper.
This I know from ample experience...sigh.
Tips to cut back flowering perennials
Coreopsis
The photo above shows what a Moonbeam Coreopsis looks like when left over the winter.
This is actually a plant that I would never cut back in the fall, even if I did clean beds then. I've found that the only way I can get this to overwinter consistently is to leave the dead growth for winter cover.
There actually was a time I'd do a more thorough fall clean up and I had to buy and replant the coreopsis more often. Now, however, with leaving the foliage over winter, it just gets bigger and bigger.
To clean up non-woody perennials like coreopsis:
- Cut all the dead, browned stems back.
- Don't just pull, as the plants are often shallow-rooted and you will pull up the plant.
- Try a combination - mostly cutting with a bit of pulling just to remove any brown stems left behind.
- Remove any weeds or encroaching seedlings from other plants.
Note: the green leaves you see in the before photo are actually seedlings of an early spring blooming geranium-type plant which I pulled. It's really not too aggressive, and it blooms and leafs out earlier than many other plants, so I leave it - pulling the seedlings and sometimes replanting them in hard-to-grow areas. You can see the clump I left to the right in the after photo.
Yarrow, Sweet William, Hardy Geranium
This is the farthest corner of the flower bed from the house and holds yarrow (right corner), sweet william (center), and a mystery hardy geranium (upper left).
You can also see here that the grass has really taken over.
After lots of cutting back using the techniques above and weeding of the grasses, it looks more like a flower bed again.
Yarrow Tip: I don't clean up the yarrow completely now - it's a plant I often lose, so I like to see where the new growth is and will clean it up a bit more in May.
Now all that's left to do is layer on the newspaper and mulch. With this clean up and then the layering paper and compost I won't have to do anything to this bed other than deadheading through the season.
The compost will break down and provide all the fertilizing the plants will need.

Do you leave your soaker hoses on the ground all year? The cleanup images are very helpful and encouraging.
Jami says
Yes, I do. I could never pick them all up! Not only the work, but they are all weaving among the plants and I wouldn't want to hurt them.
I'm glad this is helpful, Linda!

Wow! That before and after looks great! What I have the most trouble with is my edging. Every spring I dig a new edge because grass has begun spreading into my beds. Then I shake the dirt out of each sod clump I dig. If the ground is even slightly wet, the dirt doesn't shake out. It's a pain. And I think my beds are getting bigger every year from this method. And even when I'm done, I fill the area with mulch, but weeds grow on the exposed dirt along the freshly dug edge because I can't cover it vertically, if you know what I mean.
How do you re-edge your existing beds each spring? Is it a similar process or am I missing something?
Jami says
That's what I do, though it's not really deep enough to grow grass, etc. on the exposed edge. Maybe fill your beds with a bit more soil or compost?
In my experience, what you're missing is the newspaper part. So edge and weed and then lay paper before the mulch. Lay it thicker along the edges (you could even do cardboard there if you don't plant there) and then lay mulch a good 1-2 inches thick. That should last you until next spring and you shouldn't need too deep of edging.

Wish I had a post ready to link this week, but I just don't. Not too much happening in our gardens here in the foothills as we're a week or two behind those of you in the lower elevations of the PNW. I did manage to get some lettuce seed started, though, and I did pull a few weeds from my flower bed... Hopefully, I'll have a post to share next week. 🙂 Thanks for hosting!
Shannon says
How easy is it to plant after you've spread the paper and mulch? I'm putting off weeding for a bit because I know it'll get crazy again before we really get to get out there again (I live in Seattle.) However, we plan on doing a lot of planting this spring and wonder if the paper/cardboard would make it too hard for planting and is really more for maintenance. Thanks!
Jami says
If you know you're going to be planting in an area, be sure to use newspaper because it will be easier to cut through than cardboard. I just spade right through everything, and then repaper and mulch when I'm done. The paper is already wet enough at that point - in fact cardboard will be, too, and I've cut through that if I've needed to. It's just that newspaper is easier. 🙂
Rhonda says
I spent my weekend the same way and ohhh I loved it!!! I was laughing out loud at your comment about the Clematis as I can't keep them straight either and glad I'm not alone!
I cut mine back this weekend also. Garden on!!
Angie Wright says
I'll need to do this Friday when Darren is off. I need a truckload of mulch, our mulch area is still really saturated. The beds look pretty good, but yes, they need the paper and much for sure. I have a couple of plants that I didn't know if I should cut way down or not, but I think I'll follow you list and see what happens. Thanks!!
Lisa Lynn says
Your gardens look so nice and ready for spring 🙂 Mine are covered with snow! I had to make do with cleaning out my 'root cellar.'
tasty travels says
Awesome job cleaning up! I did some of that today. We've had some amazing weather!
Barb @ Frugal Local Kitchen says
I've been slowly cleaning mine up. My oldest son is supposed to help since I'm paying him. Anyhoo, I've been pruning the rose bushes next to our driveway to make that bed look nice. I try to fill a trash can with the rose prunings twice a week so they can go out with the trash.
Little Sis says
Thanks so much for hosting! Looks like you made great progress - wish I'd been able to get as much done. We're back to 45 and cloudy here, but still, that's not winter. It's coming!!
Sakura says
Our weather has been nice over the last few days, I'm going to start cleaning up. The problem I have in Utah is you never know if another big storm is going to roll thru. I don't remember my yard looking so bad last fall!
Manuela@A Cultivated Nest says
I started cleaning up my beds too. I try to do a little bit each day the weather is good and so far we've had several nice days. I find that I have better success over wintering plants if I just leave them alone all winter. Especially my hydrangeas! So my spring clean up always consists of cutting things back.
