In Seattle our cool season annual weeds are popping up their tenacious little heads again this autumn. Among them — Shotweed. It loves our mild temps and gentle, if persistent, autumn rains. Despite being a weed, it can be quite lovely carpeting flower beds in a lovely brilliant spring green. But as lovely as it can be, it is still a weed. So, after introducing a client to it in her own garden earlier this week, I realized it was time to remind all of you gardening readers that this weed is a multi-season menace. As in February when I first posted this article, now’s yet another time to work on clearing it out of your beds. Read more in the original post that follows:

Managing Weeds in Seattle — Shotweed
Wednesday, October 21st, 2009Midwinter Garden Clean Up
Monday, January 19th, 2009Finally Seattle is getting a weather break. The sun is out, and the sogginess is, well, a bit drier for the moment. It feels like Spring! This combo gives your itchy garden fingers the perfect opportunity to get a little work done before wintery weather returns…and you know it will. This is only January for goodness sakes!
Here’s a quick list of garden work items for a midwinter Spring break:
- Cut back spent perennials: Cala Lilies turned to mush? Asian lily stems, mum stalks, gaura, erigeron, hosta, and peonies bent, browned and lurking? Cut them back now. Likely, you’ll see tight green growth below all the brown…well, except in the case of the lilies which are hiding deep in the soil. For a true gardener, this work is especially rewarding. I’m always finding treasures tucked into the beds; things that I’d forgotten since they were in their splendor months ago last spring/summer.
- Cut back spent grasses: Miscanthus, switch grass and other true seasonal grasses are about done for the season. Yes, you can leave them up to catch the sunlight. But, if yours look anything like mine did after the snow, the garden will look better with them trimmed and tidy. Plus, if you cut them now, you won’t need to worry about damaging new growth that will start emerging, possibly, as early as next month.
- Look for blooms: Last week I posted a few blooming finds in my garden for Bloom Day. Just a few days later while working in the garden I found even more Hellebores popping up their heads, a few primula blooming and lots of buds on my Azara to watch over the next few weeks; it will be blooming soon. Plus, as I crawed around on my hands & knees, fragrant Sarcococca perfumed the garden.
- Cut out Crossing, rubbing, damaged, dead & broken stems and suckers: Deciduous plants are dormant. Seeing “bad lines” and damage is easiest when they’re in this state. Even if I’m working with a plant that has already set flowering buds, I may decided to remove a bad stem right now. Once it flowers and leafs out, I may have a hard time finding that problem spot — or I may forget about it entirely.
- Weeds: It never ends, right? Creeping grasses are everywhere. Shotweed is popping up. Dandelion, which could make a fantastic winter salad green, is rooting in. But the soil is loose and moist. Everything is easy to pull, so get them out now!
- Mulch and top dress: Yes you can! If you clean out a bed, yes you can mulch. While beds are dormant, adding mulch is a great chore to get done.
- Examine Seedlings: Lots of little seedlings are popping up, and not all of them are weeds. If you know what to look for, you might find some fantastic babies to move around the garden. I found a huge crop of snow-in-a-mist yesterday…almost enough to give in and call it a weed!
There are plenty of other chores to work on, but that’s a great start. Avoid the temptation to rip out things that you think might be dead. Odds are many will come back to life next spring. True, I found a couple of plants that I’m certain are dead (my Eryssium-turned-tumbleweed, for instance). But, if you’re not sure, I encourage you to encourage the plant to keep on keepin’ on. Spring is months away. Right now, we’re just getting a tease!
Why & How to Weed Now!
Monday, June 9th, 2008Late spring is such a beautiful time of year. Everything is freshly leafed out. Flowers brighten even the dullest of shrubs. Even on grey, rainy Seattle spring days the beauty of spring is refreshing and almost jarringly alive. Digging into the soil awakens scurrying beetles and various milli- and centipedes. Fat worms and young tiny ones wriggle through the moist, warming soils. And, amid all of this various seasonal beauty, weeds erupt so fast we can almost watch them grow.
Weeds made up a classification of plants that I admire, sometimes more than many of the persnickety ornamentals that take years to establish and take off in the garden. Don’t get me wrong, I would prefer less weeds and more strange and wonderful oft unseen plants in my garden. But, let’s be realistic, weeds happen, and we need to figure out how to live with them — in balance.
In my own garden I have a fairly high tolerance for weeds. They pop up in abundance, and I pop them up and out as I can. This means some areas get over-run with grass weed, shot weed, chickweed, nipplewort, dandelion, fireweed, vetch, braken fern, dock weed and others periodically. But, through the years I’ve learned a few tricks for keeping each of these under control — even when I don’t have the time to eradicate every sprout right away.
For the taproot weeds like dandelion and dockweed, I avoid tugging and yanking without a tool to ensure I get the taproot out. If I pull off the top and leave the taproot intact, these plants have so much stored energy in that big root that they tend to build a stronger root system in response to my 1/2-effort weeding work. And, I end up with a stronger weed in the end — and possibly more of them!
But, sometimes I’m passing through an area of the garden, and I don’t have my tools, and I don’t have time to go grab them. Rather than leave a flowering dandelion head in place so it can spread its seed the minute I walk by, I pop off the flower or seed head and carefully dispose of it. I leave the rest of the plant intact to pull properly later. By only removing the flower/seed portion and leaving the rest of the plant intact, I avoid causing the plant to hunker in and grow stronger. Later, when I have time, I return and remove the entire weed using my garden fork and hori-hori.
If I happen by a cool season annual like shotweed, I pull them easily by hand (tool or not). Ideally, I pull them before they have set seed or the seed will fly everywhere when I pull it. If the seed flies, I likely create multiple plants in response to the single one I just removed. And, when I pull weeds like shotweed and fireweed, I am careful to deposit it into yardwaste quickly. These amazing buggers can replant themselves if they are uprooted and left in the bed.
Braken fern is a difficult bugger in my garden. Like with horsetail, which I fortunately do not do battle with in my own garden, it is one to pull and break. Yes, the broken roots will be encouraged to branch, and a new frond will pop up somewhere else. But, remember that root systems do not store infinite resources. So, by pulling regularly, you will be depriving the plant its ability to photosynthesize by which it creates its own food. Eventually, the roots will run out of energy. It might not run out in your lifetime, but we can hope, right?
Vetch is another spring nasty that winds its way through my overflowing perennial beds each spring. I do my best to trace its twining stems back to the point of origin and pop out the entire plant. When its emergence point is located, vetch is easy to pull. The problem is in finding that point! If you cannot find it, do try to remove the stems so that the plant does not set seed and spread. The good news about vetch? Bees love it, and it a nitrogen fixer. See, weeds can give back!
Bindweed (aka morning glory) is another nasty that so many of us battle. At our best, we unwind it from our trees, shrubs and flowers, and follow the vine back to the soil where it emerges. Then, we dig and follow the root to its point of origin, taking out every last bit. Yes, I’m laughing too. Getting every last bit is nearly impossible when the root dives down suddenly several feet and travels under our neighbor’s retaining wall. But, we do our best. Remember, it takes just a tiny bit of this root for the vine to re-emerge. And, a broken root means a branching root. So, if you break it and leave it in place, more than one shoot may emerge next time. But, keep pulling and consider this one to starve.
Grass weeds, like so many others, have an uncanny ability to adapt to every spot where their seeds land. These plants can grow in a lawn where it is mowed regularly. In this situation, the weed may only grow to 2″ tall before it sets seed and spreads. Then, in another garden bed, the same plant may grow 2′ tall before it sets seed and spreads. Some have roots that travel while others have shallow rooted roots that stay intact. Try your best to pull the entire plant, roots and all, to reduce the likelihood that you’re pulling in the same place a few weeks later. All over Seattle, grass weeds are thriving in the cool, wet weather that alternates every few days with warm sunshine. Ideally, pull them before the seed begins to disperse and the soil hardens in summer. For those with travelling roots, do your best to get all the roots!
Truly, weeds are adaptable. And, unfortunately, the slugs and weevils don’t seem to favor them. Ah, that we could put the fauna pests to work in eradicating the flora pests! Now is the time to get out and pull the weeds from your beds. If you have only a few weeds, pull them before you end up with a field of them. If you already have a field of them, set aside a few hours and eradicate them before the weather changes toward summer.
Right now, as we continue to receive abundant rains, our soils are still loose and easy to work. Ideally, remove deeply rooted weeds several hours after a good rainfall. This will ensure that the soil isn’t completely saturated. Having it moist but drained will reduce your compaction impact and will make pulling weeds easier.
Don’t have time to pull all those seedy weeds? Consider, at the very least, removing the seed heads to reduce the weed’s ability to spread its progeny. And, put a note on your calender to get out and pull them soon after or you’ll be repeating the cycle in no time.
Wondering about using weed killers? I’m not an advocate of applying herbicides in the garden. Yes, there are some instances where a one-time treatment may be necessary. However, I do not believe that they should be used as a regular method to control weeds. Frankly, when I see a garden with beds devoid of any weeds, I avoid it as I would a toxic waste dump. Sure, it may seem easiest to apply a chemical to the garden to do your chores for you. But, I’m not going to advocate for this. And, really, I think that’s a whole other discussion for another time. What I will leave you with is my belief that we become healthier by working with the soil and the garden. Our children learn and our pets thrive in a diverse garden space devoid of chemicals. So get out there, breathe in the clean, fresh fragrance of spring. Dig your fingers in the soil. Embrace the earth. Grow!
Garden Coach on Noxious Weeds – What Are They & What to Do About Them
Wednesday, January 30th, 2008Weeds come in many forms. They are defined in many ways. Though they may be “a plant whose virtue has yet to be discovered” (Emerson; see earlier post), they may also be dangerous to humans, livestock or the overall ecology of the area. Because some weeds fall into this more “dangerous” classification, going beyond just a mild annoyance to the person tending a garden, various federal, state, county and even city-wide agencies rank weeds into various classification categories. In Washington State, we have a State-wide noxious weed board, which ranks weeds into three basic categories:
- Class A: Non-native plant in limited in distribution in Washington and require eradication. Example: Giant Hogweed
- Class B: Non-native plants in limited distribution in some areas, absent in others and in wide distribution in other areas. These weeds must be contained in existing areas and all efforts made to keep them from spreading. Example: Herb Robert (aka Stinky Bob)
- Class C: Non-native plants in wide distribution throughout the state. Counties may enforce eradication or work on educating public about the weed’s issues. Example: English Ivy
For more information on how and why weeds are placed in each class and how to manage them in your own garden, visit the Washington State Noxious Weed List Webpage. If you live in the greater Seattle area and would like help differentiating your weeds from your desirable plants and getting tips on how to deal with the weeds once you have identified them, please contact Garden Mentors for a weed-identification session now!
Gardening in the Winter
Monday, January 14th, 2008WSNLA invited me to write an article for the Kplu.org and WSNLA.org information websites on the subject of gardening in the winter. Read more here if you’re interested in tips for gardening and caring for gardening tools now in order to make your garden lower maintenance for spring and summer.
btw: I have no idea who decided to call this “mowing in the wind” since this piece isn’t really about mowing at all.
Winter Weeds and Winter Weed Control
Tuesday, January 8th, 2008Although the temperatures in the greater Seattle area are hovering somewhere above freezing but below 50 degrees, weeds are still quietly establishing themselves in gardens throughout the area. If you can get out there and remove them now, Spring garden care will be much easier as your weed population will be significantly reduced.
- Grass weeds are spreading, weaving their way through shrubs and laying down roots in dormant perennial beds.
- Cool season annual weeds like tenacious shotweed is germinating, flowering and even releasing seed!
- Perennial weeds such as Stinky Bob (aka wild geranium) and feverfew (which I consider worth growing but controlling) are holding on tightly, photosynthesizing to feed their spreading roots underground.
- Fireweed is tight to the ground but feeding its powerful roots beneath the soil
- Taproot-pros like dandelion continue to feed themselves quietly, ready to power up as soon as the days begin to warm
So, what to do about all these (and other unwanted garden plants)?
If the soil is frozen or soggy, take care not to trample your garden beds. You can damage tender, unseen perennials lying dormant, precious plant roots and soil structure. If you can access the plants try some of these methods to put your winter weeds to rest:
- Get out your hand tools and pull the plants from the roots. (If the soil is frozen, you might wait until it thaws so you don’t just break the top of the plant off, leaving the root intact where it may regenerate…often more powerfully than before.)
- Pour boiling water over the unwanted weeds. Hot water can often shock the life right out of them.
- Crack out the flame weeder and cook the little buggers, but take care not to overdo it, starting a fire or damaging your desirable plants
And when you’re done removing the weeds, be sure to add a thick layer of composted mulch over the area. This will help your remaining plants and soil thrive while starving any remaining seeds from light, which they need for germination.
What is a weed anyway?
Tuesday, June 26th, 2007One of my favorite descriptions of a weed is a “plant whose virtues have yet to be discovered” (Ralph Waldo Emerson). Another favorite is ”a plant that can out-compete others in adverse situations” (not sure where I heard that one). Today, for me, a weed is something I ripped from the ground and deposited into my yard waste bin. I’m making progress & so glad I got out there today. The soil is starting to really dry up for summer, which means weeds that are easy to pull today are going to be a much more difficult to pull next week. Actually, the ones struggling for life in an area I’ve compacted in anticipation of installing a new patio, were pretty tough to get out.
If you see any of those little buggers in your yard, I’d encourage you to get out there and remove them sooner rather than later! (Oh, not sure if something is a weed or not? This is my favorite weed id book.)
Weeding, Pruning, Planting & Harvesting
Friday, June 22nd, 2007Today I woke up unmotivated for yoga, which is really unusual for me on a Saturday morning. Granted, I had several glasses of wine with friends last night, which I’m sure contributed to my general morning laziness. So…I skipped yoga & that was a-okay today!
Bob and I had time to enjoy a big, homemade breakfast on the back patio together after being quite lazy for the first few hours of the morning. I ran the drip irrigation in the early morning to get the soil moist, both to pamper my plants and ready the weeds for their immenent departure from their plush locations amid my more desirable perennials and shrubs. After breakfast, I appraised my garden (and its many, overwhelming needs) and set forth with tools & weeding container in hand.
For a couple of hours, I pulled weeds methodically in the most desperate areas. (I also cleaned up garbage! Ugh! We had our roof replaced last year & I’m still finding old roof junk in my garden beds.) I pruned back a hebe that wants to grow across our main front pathway. I finished up by harvesting the first batch of new potatoes. I try to keep several batches growing in cycles thru the season, but the first is always the most exciting to bring in. (Sometime I’ll put together an article on how I successfully grow potatoes & why I won’t eat any non-organically grown root vegetables, but that’s another story for the gardening forum or library….)
Today’s potatoes were luscious, thin-skinned white potatoes. The harvest was relatively small, and I’m not sure why. The plants were pretty weak. Granted, I did plant them up pretty early in the season, but I’m still a little curious what happened. My batch of red potatoes, which will come in next, is going to be enormous. I think the next ones I set out will be Yellow Finns, which are just great!
While I was working in the garden, I noticed that I have several small tomatoes forming (yay!), the chard is just begging to be harvested & sauted to go with potatoes tonight, and the lettuce is going to bolt if we don’t start eating a lot of salads soon! Oh, and on a floriferous note — my Dierama are starting to bloom! It must be summer!
My beets are kind of disappointing. Something is munching on them & they aren’t forming great roots. If anyone has tips on growing great beets, I’d love the input. Mine seem to be hit or miss.
The strawberries are still pluggin’ along. I took a huge bowlful over to our friends’ last night. The raspberries are starting to come in. I picked some with my favorite team of garden helpers (the neighborhood kids). Anyone surprised that most made it into the kids’ mouths rather than the berry bucket?
Well, time to shower up & get all this dirt off. I may just reward my gardening efforts with a nap on my lounge chair in the meditation garden.
Happy sunshine everyone!
