It’s hard to believe, but the Northwest Flower & Garden Show opens one week from today! That means the show garden designers are scrambling for last items before they start building fantasy land in the Seattle Convention Center this weekend. The insanity starts on the empty convention floor on Saturday morning and continues until noon on Tuesday when designers are herded out the doors. Then, the judges enter, awards are made, and the spaces take a bit of a rest before the Arboretum Foundation gala later Tuesday evening.

Mossy Carpet Incubates Ferns & More
I’m a card carrying member of the Seattle Arboretum Foundation, so along with all the other members I received a notice today asking for donations of moss for their show garden. Without giving away too much fact-behind-the-fantasy, I’ll just say that moss is used to help give a finished look to the “ground” of the show gardens.
If you have moss that you’re wondering what to do with — and I know many of you do — consider taking some time this week to hand-remove it and donate it to the Arboretum Foundation.
Put those Moss Out! bags back on the shelf. Leave the chemical aisles, and enter the garden. Moss is easy to remove from rooftops, lawns, hanging from trees, and shady cracks in the patio. Just take a rake to the lawn, a flat shovel to the garden beds, a trowel or hori-hori to the patio cracks or a push broom to the rooftop, and watch the moss roll away. If you have hanging mosses, gently lift it from branches. Do not peel lichens from branches or you may disrupt the tree’s cambium. Do take care removing large “sheets” of it from forest floors. Moss forms an important part of the forest ecosystem and acts as a sponge for water that helps the forest floor stay cool and moist. If you remove some from these areas, please don’t take it all!
Here’s where to drop your moss donations:
- Moss deliveries may be made to the Seattle Park Arboretum between 10am-4pm any day this week. Place moss in the two large wooden cold frames beside the weather station at the west end of the main green house next to the Graham Visitor Center at 2300 Arboretum East Drive. Saturday, February 14th, is the last day to drop off donations until noon only. For more information contact the Arboretum foundation at 206-325-4510.

Hey Robin,
What methods do you recommend for removing thin layers of moss that collect on cement stairs and walkways? These layers aren’t worth harvesting as it’s too thin – but I have heard conflicting advice on the best ways to get rid of it without staining the cement and/or poisoning the soil.
Halley
Halley, thanks for the question. Honestly, I usually just get out a blunt-nosed shovel and use it to slice downward and crossways on cement to remove moss. And, believe me I have quite a farm of it in the concrete that probably dates back to around 1914 near my house. Some of the slicker layers can be a little more difficult to remove, but I like this method. If you still have some of those green slime layers like I’ve got on my patio after our wet winter, go at it with a pressure washer in spring or after short dry spell in winter. That usually does the trick. Frankly, less chemicals = more in my book!
Hope this helps
I love moss but don’t have more than a couple of tiny patches, so I hope others will pitch in for the donations. Only in Seattle! What do some folks call us, Mossbacks? Maybe I should look in the mirror and see if there’s any growing on my spine!
