The WILD WORLD of WEEDS

Garden Pests or Special Guests?? Discover fun facts about “weeds” commonly found in yards around the Pacific NW!

Weeds get a bad wrap. There, I said it. I know, you’re probably saying,

“What for all this here crazy talkie-talk!! Horsetail and Morning Glory just ate my house!!”.

But, as it turns out, what each among the more regular cast of characters, appearing in your garden, have in common is, when confronted with poor soil conditions, 1.) they put most of their energy toward seed production, as a survival strategy, and 2.) this, in turn, brings new & abundant sources of organic matter back into soil, which then replenishes & amends it to levels, more suitable for encouraging & sustaining other kinds of plants, trees, etc.

So, ya see, they’re just here to help with (and hopefully, survive) your crappy soil. If you don’t want so many weeds in your garden, MULCH more regularly. Spreading 3-4″ of MULCH throughout your garden, once a year, takes a whole lot less time, than fighting it out with the “encroaching battalions” of weeds, all the rest of the year. That said….

As was discussed in a previous article (“Organic vs. Chemical Lawn Care”), weeds can serve as “indicator plants“, meaning, by knowing a bit about various common weeds and the kind of conditions they prefer, the presence of certain weeds in your lawn or garden can help give you clues as to the general health, structure, nutrient content, fertility, pH level, etc. of your soil.

But the ancient and rich history of human beings and “weeds” extends far beyond that to commonly available food sources, medicinal uses, in companion planting, as livestock feed, as cover crops, as materials for the production of various kinds of textiles, as pigments in paints and dyes, to all manner of amendment, extraction, repellent, attractant, glue, tea, tincture, and much more!!
