The 2010 January Seattle Winter Garden

Thursday, January 21st, 2010

Today, at the end of January, we’re having a week to remember. Record high daytime temperatures even, on a few days, under clear sunny skies. After wrapping up my handouts and PowerPoint presentation on Ornamedibles for the Northwest Flower and Garden Show in February,  I got out in the garden to get caught up on a few chores. I certainly have many more to complete before Spring really arrives, but for now, here are a few things you might try to accomplish while the days are warm and dry and your plants are still dormant:

Pruning: Yep, now is a fantastic time to get out and prune your woody plants. Without leaves in place, it is easy to see any broken, crossing, downward-facing, or rubbing branches. In my own garden, I dropped a few crotches off my Acer triflorum to create new leaders, encouraging the plant to grow in directions away from the utility lines it is early reaching these days. As well, I trimmed out some crossing and rubbing branches on my dwarf Japanese Maple and my Heptacodium. And, I pruned out some Viburnum carlesii branches that were growing toward the house (yes, I’m giving up some lovely blooms that will shortly open, but I had the time and the access, so cut I did!).

Cut back Perennials: If you didn’t get it done in fall, now is a good time to walk through your beds and cut down the bits and pieces of perennials that have died back. On warm dry days your beds are less likely to become compacted by your footsteps. When the ground is frozen or soggy, your good clean up works may detrimentally impact your planting beds. Today in my garden I cut a couple of Miscanthus to the ground, chopped down spent lily and Phygelius stalks, and cut back the more withered semi-evergreen fern fronds.

Raking & Mulching: Honestly, I didn’t get to this today. Since I didn’t have mulch on hand, I held off on doing a full raking of all my leaves. It may be warm now, but it is still January and another freeze could happen. I did rake up some materials, but I left leaf duff in place to continue to deter weed growth while also adding nutrients to the soil, protecting soil microbia habitat, and protecting roots. When I do find the time to load up my truck with mulch, I’ll start really raking those leaves up, pulling weeds and protecting my cleaned beds with a fresh layer of composted organic mulch material.

Pull weeds: This is another work item I noted but didn’t do today. Most of my beds are fairly well protected with leaf duff or mulch, so not too many weed seedlings are showing up yet. Still, I did see quite a few rosettes of shotweed popping up here and there. Soon, if this weather keeps up, I won’t be able to continue to ignore them.

Breath deeply: Or at least pay attention to what’s in bloom. My own Witchhazel is beginning to fade just this week — the weather is a bit too warm for it. Hellebores are starting to really show their stuff. Camellia sasanqua are still popping open here and there. Sarcococca is almost too much to take each time I open the back door, but it still smells like spring is almost here. And, it may not be fully blooming yet, but I noticed a petticoat of yellow on my Azara,  promising chocolate fragrance is soon to be wafting through the garden.

Step carefully: Bulbs are coming up. Tender perennials are sending up shoots. The garden is coming to life. Mark your bulb locations when you find them and tread lightly so you don’t damage tender new growth.

More than anything, if you’re in Seattle, find the time to get outside right now. If you’re an office worker, take the time to walk in a park at lunch. Or heck, just ditch. Life’s too short to miss spring-time in midwinter!

Managing Weeds in Seattle – Dandelions

Friday, October 23rd, 2009

Okay, you liked the reminder from earlier this week about the return of autumn Shotweed? Well, here’s a reminder that the dandelions are showing up again. They love this weather. The damp soil allows them to really power up their tap roots. So, get out there and carefully remove them now. Read more about removing dandelion and putting those weeds to good use: (more…)

Managing Weeds in Seattle — Shotweed

Wednesday, October 21st, 2009

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:

How Much Time Does a Garden Coach Spend in Her Garden Each Week

Wednesday, May 20th, 2009

Yesterday I was helping a regular client prune several woody shrubs away from a deck she’ll be renovating this summer. The shrub work was long past due, but together we made great progress. As we were working she asked, “Robin, how many hours a week do you spend working in your garden?”

Stone & Filled Beds Make for Easy Summer Care

Stone & Filled Beds Make for Easy Summer Care

Hmmm…that was like getting the job interview question you’re completely unprepared for. Fortunately, I wasn’t interviewing for a job as the question gave me pause. How much time do I spend working in my own garden in a week?

I answered my client honestly. I barely have time and energy left this time of year to get out in my own garden. My hands are exhausted from pruning and weeding and typing and writing all day, so my own weeds flourish and my shrubs thrive despite the work I know I should devote to them.

Fortunately, I’ve invested almost a decade developing my garden, which has a lot of stone work. And, stones don’t require a lot of maintenance. And, my beds are quite full from years of planting, dividing and spreading perennials. Some I regret and now classify in the weed department (Alstromeria & cat mint rules this regret.) Still, I would like to have garden perfection with zero weeds, perfectly coiffed shrubs and pest-free cabbages.  But, time is at a premium. And when free evenings bring lightening storms and hail such as we had last night, I miss out on my rare opportunities to weed away the evening sunlight.

So, to answer the question. I find myself puttering through the garden with coffee each morning most days of the year for a good 30 minutes or so. I visit my potted garden and greenhouse for about 30 minutes a day in spring and summer (at least). I visit my veggie beds daily to harvest (if not to weed and plant and water) for about 20 minutes a day. And, when I have an actual day to really get out there. Well, those are the days I can put in a good 8-10 hours renovating big spaces and making progress pruning those shrubs, pulling those weeds, squashing those slugs and dressing up the finished areas with a nutrious layer of composted mulch. And, of course, I try to wind down sunny evenings sitting in the garden with a glass of wine or iced tea — and odds are, I’ll pull another weed while I’m at it. So shall we say I spend a good hour or two, on an average day, working in the garden (and sometimes quite a bit more.)

Now that I’ve wrapped up this thought, I’m going to escape into my own garden for a rare two hour, mid-day weed-a-thon. Wish me luck!

Garden Coach Teaches You to Eat Your Weeds!

Monday, March 2nd, 2009

That’ll serve’m right…right? Turn annoying garden weeds into a delicious snack you crave. Get paid back in nutritious energy foods for all the hard work you put into pulling those suckers out! Just hope you don’t start craving them just as you eradicate them!

Fresh Nettles & Nettle Tea

Fresh Nettles & Nettle Tea

So, maybe you’re skeptical about eating the weeds that volunteer in the garden. You’re not alone. I still haven’t tried eating shotweed, and I’ve got more than one bowlful of salad makings from that sucker out in my garden. I have been spying my dandelion leaves a little more closely. When I they get just a bit bigger, but before they start budding to bloom, I’m planning to harvest them to eat this spring.

Our gardens create a bounty of weeds during the growing season, and I continue to be amazed at how many of them are edible. Let’s be clear, you need to know how to identify the plants before you go eating willy-nilly in the weed patch. But, once you know what you’re pulling, odds are your compost bin will be a little lighter, your wallet a little fatter and your belly a little more full. Looking for a larger list of edible weeds? Check out the Tilth Maritime Garden Guide to start.

This weekend at the farmer’s market, the local foragers (Foraged & Found Edibles), were offering bags filled with fresh stinging nettles. The name sounds scary, and it should. If you get scratched by the nettle barb, you’ll get a nasty stinging rash — that goes away pretty quick. But, if you can harvest this wild plant successfully, you’ll have a fantastic green that tastes a lot like spinach. It’s packed with vitamins A, D and C. And, it’s been the first greens of the season eaten from the wild by Pacific Northwesterners for, well, who knows how long. Even my favorite recipe book, The Herb Farm Cookbook (available here in the books section), has recipes using this weed!

Weedy Smoothy

Now, I’m not likely to go foraging for this green myself, but when a big bag filled with this weed is offered by local foragers, from local forests, at prices less than the cost of a bag of local farmer’s market greenhouse-raised kale, I’m going to snatch it up.

Gingerly, taking care not to get “stung”, I dumped about half the bag into a steamer pot and steamed it for a bit. All recipes promise that after cooking briefly the nettles’ sting is gone. Still, steaming left them looking a bit fuzzy for my taste, so I dumped them in the boiling water for a bit longer. We used tongs to squeeze out the excess water as we mounded it onto our plates, and then we splashed the pile of weedy greens with vinegar (something every weed hates). They were delicious, and I’m not dead yet!

In years past, I’ve enjoyed nettle tea (aka swamp water), so we saved the cooking water, which wasn’t salted. However instead of drinking just the nutrient rich cooking liquid, I added it to our morning smoothie, and it was fantastic. Here’s a recipe for making your own weedy smoothie.

Make it and take it out in the garden as fair warning to all weeds — sprout here and you may just become my dinner…or breakfast…or even high tea!

Important Note: As with any new food, take care trying it out for the first time. Food allergies lurk in places we may not expect. Try a weedy diet at your own risk and to your own health!

Nettle Weed Smoothie Recipe

  • 3/4 cup nonfat plain yogurt
  • 1 cup frozen peaches
  • 1 cup frozen strawberries
  • 1 cup apple juice
  • 1 cup nettle juice
  • 1 T. honey (optional)

Place all ingredients in blender. Blend on high for about 5 minutes or until the fruit is pureed. Pour into tall glasses and enjoy. (serves 2)

Eat Your Corn! Biofuel Can be Derived from “Useless” Weeds!

Thursday, January 1st, 2009

On this, the first day of a new year, 2009, I am reminded of one of my favorite sayings: “A weed is a plant whose virtue has yet to be discovered.” (Ralph Waldo Emerson). And, this comes with some pretty cool news!

Word has it that a weedy, seeming useless African plant offer biofuels that can even help power up a jet! And, the Jatropha doesn’t produce anything we can eat (or feed to animals we eat). Sure, it has its challenges and it isn’t a 100% petrol alternative, but I was glad to read that Air New Zealand is actually testing this out and the Honeywell corporation is investing in alternative fuel development. My favorite statement about this testing from Honeywell: “We just adapted what we tend to do in a [oil] refinery for this application. This is not rocket science, we feel very comfortable scaling this up.” The saddest statement: “Eighty-five percent of the cost [of the biofuel] is the feedstock,” Holmgren says. “It’s pretty hard when the jet fuel made from oil sells at a lower price than soy.”

And, apparently, it can be grown in some pretty rough environments — ones not good for growing our food. The fuel from this test was grown in places like India and Mozambique. Dare I suggest that something like this might be an alternative crop to poppy? Keep on savoring your soy and your corn and even your corn-fed beef, if that’s what you’re into.

As a member of the tenacious Euphorbiaceae family, which also includes that Poinsettia you’re about ready to compost after the holidays, I’m not surprised to hear the Jatropha genus can grow in rough spaces. Here in Seattle, we battle a few Euphorbia weeds, and we often plant Euphorbias in our drought-tolerant gardens. They’re beautiful and not very thirsty. They can be toxic, even causing chemical burns to some gardeners, but they’re unbeatable for their beauty, easy care and tenacity. It’s nice to know that their toxic sap may have a great use for humanity — giving us the power to travel! With enough testing and investment, perhaps this “weed” will provide a complete alternative to deadly, costly petroleum. In a year that promises change, this is a bit of good news for the future we need.

Freezing Weather Kills All Garden Pests & Weeds!

Monday, December 22nd, 2008

Sorry to disappoint you, but freezes don’t kill all the garden insects. I lied. Still, some of the flora and fauna pests took a beating this week. And, unfortunately, others may be trying to make your home their home. Despite the freeze, critters are buggin’ out there!

Adult slugs are probably done for the season, but their eggs are laying dormant waiting for the temps to get to around 40F before they burst forth to forage for food among our snow-tortured, blackened plants. Root weevil larvae is resting quietly in dormancy, deep in the soil where it is unlikely to freeze. (And knowing those suckers, it’s unlikely that a freeze would take them out anyway.)

Abandoned Papery Hornet Nest in Winter

Abandoned Papery Hornet Nest in Winter

Bee nests, like this hornet nest, should be vacant after a deep freeze. And, the bees won’t repopulate it next year. Taking them down to explore with kids is fun — if the wind hasn’t blown them away already. Only approach them if you KNOW the weather has frozen and the nest is abandoned. And, as much as you might think of hornets as a pest, remember they have lots of beneficial purposes in the garden too. Plus, they aren’t aggressive so long as you don’t attack their homes!

And, a freeze isn’t going to do a darn thing to stop weed seeds from sprouting. Seeds can remain frozen for years and still remain viable. So, unfortunately, we’ll all be weeding next spring (or even sooner if the weather gets back to normal).

So the good news is, adult slugs and other bugs are probably dead and gone. The bad news is your garden is going to face a resurgence after things melt and we get back to our temperate Seattle winter. But, perhaps when those slug eggs hatch they’ll starve unless they decide to start snacking on emerging shot weed. Now wouldn’t that be a coup d’etat in the garden?!

And, rodent pests are particularly invasive during this weather. Likely, they’re moving into our homes, autos and garages seeking food and shelter from the storm. Make sure your house is sealed up tight. The last thing you want to deal with is rats, mice or squirrels taking up residence! Not only will the adults survive happily in your attics and crawl spaces, but so will their children, grandchildren and so on…

Planting a Princess Tree…or not

Thursday, May 22nd, 2008

J. Fullerton of St. James, MO writes, “I would like to plant the seed of a Princess Tree. Where can I get information on ‘how deep, where, and other information to make this a success’?”

Well Jim, I’ll start by saying that I haven’t grown a Princess Tree myself. As well, keep in mind that seed-grown means genetic diversity. If you plant your seed, you may not end up with an exact duplicate of the tree that you think is its parent.

And, since common names can refer to many different trees, I’m going to start out by saying that I’m talking about the Royal Paulownia or Paulownia tomentosa.

Please read up on on the invasive nature of this tree before you go any further: http://www.invasive.org/browse/subject.cfm?sub=2426

If you still feel it is necessary to plant your seed, I suggest you refer to  The Reference Manual of Woody Plant Propagation for detailed information.

Garden Coach on Noxious Weeds – What Are They & What to Do About Them

Wednesday, January 30th, 2008

Weeds 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!

What is a weed anyway?

Tuesday, June 26th, 2007

One 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.)
