Big, Bad Thistles

COS-CO_LAH_6707

When I spy a thistle in my yard—or in the open space next door—my first inclination is to annihilate it. Pull out the weed killer. Put on gloves and yank. Dig out the roots. Sure, some have imposing purple flowers, but I’ve learned that if you delay your war, the thistles will conquer. Then I started reading up on thistles.

Pretty Purslane?

Portulaca oleracea 'Toucan Fuchsia'_Purslane_DBG-CO_LAH_7226

What were those vibrant pink flowers? They were definitely show-stoppers, especially as they were spilling out of planters crammed full of flowers in other shades of pink plus various yellows—creamy white Cockscombs (Celosia cristata), pale pink, ruffled Cosmos and darker pink Globe Amaranth (Gomphrena), butterscotch-yellow Lantana, Petunias in either a lush purplish-pink or a pale cream with yellow throats, and finally, bright lemon Flowering Maple (Abutilon). Whoever had designed the display, situated along the walkway in front of the greenhouses at Denver Botanic Gardens, clearly had a good eye for shapes and colors. Continue reading “Pretty Purslane?”

Leafy Spurge? Noooo!!!

Jean K. Tool SWA along I-76 to Brush LAH 015

What grows one to three feet high, has small blue-green leaves, clusters of pretty yellow flowers, and is a stubborn, nasty, and aggressive noxious weed that is supported by an extensive system of underground stems? Probably the only good news is that it isn’t typically a weed in most landscapes, but if you’ve been out hiking much lately, you’ve likely encountered Leafy Spurge.

The Myth of Weed-free Landscaping

Today I’m revisiting a topic I first talked about back in 2013. I normally don’t do this, as I assume you can go back and reread whatever you’d like, using the options at in the sidebar at right. However, this is an issue that I think needs a lot more attention. I’m so frustrated, I could scream.

What is this horrific landscaping practice that makes me cringe? Landscape fabric.

What’s a Weed?

Taraxacum officinale Dandilion @DBG LAH 001

A weed is…

I subscribe to a variety of online gardening groups, mostly on Facebook. Lately there has been a lot of ranting discussion about whether or not dandelions are weeds. On the one hand, various gardeners are asking for help controlling dandelions in their lawns and gardens, often to please a landlord. On the other hand, various opinionated persons climb onto their soapboxes and extol the virtues of dandelion leaves, wine, and bee-friendly flowers, chastising anyone who would dare to disagree.

Common Mullein

plants in snow_castlewoodcynsp-co_lah_7289

After the storm earlier this week, snow blankets the fields, hiding most signs that anything ever grew there. But interspersed with the even white blanket and occasional dried grass leaves are spikes, sticking up like posts in the empty landscape. We’re finally noticing the dead and dried flower/seed stalks of Common Mullein (Verbascum thapsus).

Garden Advice: Don’t Waste Your Vinegar

Death to Weeds @TacomaWA 14oct07 LAH 037Every so often I come across an article that explains something so much better than I ever could. This is one of those times.

Tsu Dho Nimh writes a blog called Lazy Gardening SMACKDOWN. Back in 2013, he tackled the viral advice about making your own herbicide out of vinegar, detergent, and some other ingredients. I’ve been meaning to cover this topic, because this homemade “herbicide” doesn’t work. But then I saw Nimh’s article, and realized that he did a much more thorough job of explaining it all.

Nasty Knapweeds

Centaurea stoebe_Spotted Knapweed_PikeNat'lForest-CO_LAH_1141rThe flowers could be considered somewhat pretty—a white or lavender tuft reminding me of cornflowers (aka bachelor’s buttons). The somewhat pretty flowers are probably the only positive aspect of these plants. A common noxious weed, knapweed is the bane of my garden.

The problem is that we live immediately adjacent to an open space, a few supposedly wild acres left by the developer (probably because it’s too steep to build on). There’s Gambel’s oak, six Ponderosa pines, a smattering of yucca, assorted wildflowers, and some rather nasty weeds.

Garden Advice: Using Salt in the Garden

no saltOne of my perverse pleasures is perusing Pintrest to find bad garden advice. There’s certainly no lack of misinformation on the web, and Pintrest seems to collect it all. Most advice is simply a waste of time and money—sprinkling Epsom salts on your plants, spraying weeds with vinegar, pouring beer on your lawn. They don’t help, but they won’t kill your plants either. However, yesterday I came across a recommendation that will seriously damage your garden. I was so horrified that I immediately sat down to write this post.
