Visualize Tolerance – Do the Eyes Have it?

A lovely garden scene marred by floating row cover

A lovely garden scene marred by floating row cover

Everyone has their tolerance level. Whether we’re talking how many weeds you’ll put up with in the garden or how many colors you’ll allow in your palette, there’s a level for everyone.

Today as I was working in my garden, I breathed a sigh of relief as I cleared away some of the ugliness I tolerate in the garden. And, I cheered for some of the beautiful results produced as a result of my tolerance for ugliness.  I present these photos for your consideration. Tell me, what would you tolerate?

First, consider growing in a broccoli in a garden visited throughout the growing season by brassica pest known as cabbage moth (really a butterfly). To protect it, I choose to cover it with floating row cover. This cover makes it impossible for the adult butterflies to lay their eggs on my delicious broccoli, which their caterpillar generation munches voraciously. The row cover interrupts the beauty of the overall garden design. But…

…a peek under the hood reveals big, delicious broccoli without caterpillar damage…no pesticide required! Dinner anyone?

After taking a peek at my drool-worthy broccoli, I decided to explore a few other eyesores in the garden. Having just passed solstice, we’re already on the slow march to winter. Shorter days are already happening. Cool season crops are under scrutiny for harvest. Warm season crops are beginning to make headway. It’s sometimes a juggle to stay on top of it all.

I decided today’s 75F weather was enough inspiration to dismantle the hoop houses around this year’s 3-Sister’s+ garden. I add the “+” because this bed not only contains the corn, squash and bean components of a 3-Sister’s garden, but it also has chard, lettuce, sunflowers, onions and marigolds. One area is also a bit overrun with lime thyme, but the bees love it. Once they flock to that favored flower, they’re likely to take a peek at the other flowers nearby — like the squash and beans!

What Not to Eat: Poison Hemlock

Wednesday, May 26th, 2010

Earlier this month local news outlets began reporting that a woman in nearby Tacoma, Washington may have died from ingesting poison hemlock. The tale being told is she harvested it to eat – thinking it was actually something else. A wild carrot perhaps? Regardless, it was a deadly mistake nobody else should have to repeat if we work together to educate ourselves about these pest plants and be sure to eradicate them in our own gardens and communities.

Oh, and yes, this is that same toxic plant that Socrates ingested when sentenced to death. And, yes, it’s not a nice way to go. The toxins, which exist in all parts of this plant, attack the nervous system creating a range of scary, life-threatening reactions ultimately potentially causing death.

As more and more of us are growing more and more of our own food, it becomes ever more critical we stay on alert for noxious, toxic weeds in our midst. Hemlock is a weed in our area, and frankly, it’s a really pretty plant. It grows rapidly, easily reaching 8′ tall in the spring and covered with lovely carrot-family flowers that are easily mistaken for lovely Queen Anne’s Lace. But, don’t be fooled – this stuff can kill you. And, it must be eradicated – now! Why now? Well, for the most part, poison hemlock is just now in full bloom. And what follows blooms? Seed pods that get carried rapidly to new locations where they seed and spread this nasty weed to new locations.

As of the writing of this article, Poison Hemlock is a class-C noxious weed (or non-regulate weed, depending on where you read) in King County, Washington and a class-B weed in Washington State. It does not appear to be on the USDA Federal Noxious Weed list. Essentially this means the regulating committees recommend removing it, but you aren’t going to get in trouble for having it on site – unless of course you or someone else eats it from your property. Truly, the best thing to do is get rid of it. Dig it out. Pick off and carefully destroy any seeds. Be safe.

Not sure how to identify this plant? First, look for a tall, lacy formed perennial. Next, look for multiple flat, panicles of white flowers all over the plant. Take a sniff — does it smell musty? Look at the base of the plant or at the stems — are they purple or have purplish streaking? Have you cut any of the stems? Do they appear hollow? If you answered yes to any of these questions, definitely don’t take a bite. You shouldn’t need your nervous system to go haywire or your heart to stop beating to convince you it is time to take out this weed. Instead, do the right thing – eradicate it before it proliferates any further in your garden or your neighborhood.

For additional assistance identifying and understanding what makes a weed noxious, visit any of the weed list sites linked in earlier portions of this article. For additional help clarifying if your pretty, white-flowered, lacy-foliaged perennial is or isn’t Conium maculatum (aka poison hemlock), refer to the King County Noxious Weed page here.

And, once again, a reminder from one who grows a lot of her own food. Never eat anything you aren’t 100% certain is edible. Whether it’s a pretty flower, a lovely leaf or a fluffy fungi — be sure. Or you may be dead.

(And one final note: I did see this plant growing near a design client’s garden. I alerted my client who will be working with her neighbor to eradicate this weed asap. She was quite thankful for my eye toward her safety, especially since her two year old is going through the “every-plant-goes-in-the-mouth” phase of life.)

The Vine that Ate the South May Add to Atmospheric Pollution

Monday, May 17th, 2010

Anyone who has farmed, gardened or just driven through the south knows what Kudzu is. It is everywhere in the South; many say it ate the south. (Don’t ask me who coined that phrase; I couldn’t tell you.)

It is a non-native species that was introduced and then over-planted — all with good intentions mind you. Then it got crazy wild and engulfed the southern states. If that isn’t enough reason to work toward getting rid of it, today’s report that it may be adding to atmospheric pollution.

This study looked at the nitrogen fixation process, which Kudzu helps perform in the soil. And, they found that it may correlate to potential high ozone days. Although this study itself is interesting, it makes me wonder if other nitrogen fixing plants like green beans (in the legume group like Kudzu) are also potential threats.

Could we be adding to atmospheric declines by working with plants that adjust soil nitrogen? I’ve always thought (and been taught that) nitrogen fixation was a good thing. Now,  I don’t know. But, it definitely gave me pause. I won’t stop growing green beans…or red beans…or speckled beans…or winged beans…or flat beans…or scarlet runner beans…or any other beans for now, but I will be curious to see what other studies come out in this curious area.

Oh, and no, I won’t be planting any Kudzu – ever! I had my fair share of it when I lived in the south – enough is, well, more than enough!

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…)
