Don’t Salt the Soil!

YampaRiverBotanicPark-CO_LAH_6919

We all know that it’s a bad idea to pour salt on the ground in our gardens. After all, that’s what invading armies did—they salted the ground, effectively sterilizing it and therefore starving the population. Even the ubiquitous recipe for “Homemade All-Natural Weed Killer”—you know, the one with salt, vinegar, and Dawn detergent (and since when is Dawn “all natural”?)—warn against using the concoction where you want other plants to grow. Salt in the soil is bad news for gardeners.

Yes, you wouldn’t intentionally spread rock salt on your dirt, but that’s only one way to end up with soil too salty to support plants. There are other, more insidious ways to salt your soil. (more…)

Blown Away—Birds and Hurricanes

Hurricane_Dorian_(peak_intensity),_September_1,_1240Z

Palm Warbler_CapeCoral-FL_LAH_5520Dorian isn’t the first hurricane to pound the Caribbean, although she was definitely one of the biggest. Now she has churned her way through the Bahamas—dumping four feet of rain in some places—and along the southeastern coast of the U.S., causing tremendous flooding, demolishing buildings, and taking lives. Pete and I visited South Carolina and Florida last winter, and we’ve sailed the Abacos Islands in the Bahamas. Birds were everywhere. Now, I think of all those birds struggling to survive in the midst of those 150+ mph winds, and I wonder—how do such fragile creatures survive a hurricane?

Beautiful Buttercups

Buttercups. The word brings to mind a field of yellow flowers, or perhaps a young girl sniffing the flower and dusting her nose with pollen. And indeed, some of the flowers in this family, the Ranunculaceae, do make you think of a little cup filled with bright yellow butter. And some don’t.

Just the Facts, Please

Purslane_Tyndale garden-ColoSpgs-CO_LAH_2881

A few weeks ago, I wrote that I intended to verify claims that purslane (Portulaca oleracea) has “amazing health benefits.” I had read an article about this supposedly nutritional plant that seemed a little too good to be true. Being ever the skeptic, I dug in—and learned some things. I’ll use this as a case study on how to verify health claims that you read online. (more…)

August’s Yellow Flowers

What is it with August and yellow flowers? Last week Pete and I revisited the Yampa River Botanic Park in Steamboat Springs. As I expected, the gardens were in full bloom—dazzling in the clear mountain sunshine. As I strolled the pathways, I noticed expanses of Coreopsis, clumps of Rudbeckia, beds of sulfur-yellow buckwheat (Eriogonum), and sprays of goldenrod. And that’s when I realized that the majority of blooms were in some shade of yellow.

Hope for Musically Challenged Birders (Like Me)

Belted Kingfisher

It’s early morning, too early, I groan, but the air is full of sound. Even before the sun crosses the horizon, I can hear the birds calling, singing, squawking, and chirping, all right outside my open bedroom window. Granted, that’s what I get for putting the feeders up close to the house, where they can easily be seen. But still—all that noise, just because dawn is coming?

As I lay in bed, I can distinguish the cooing of the pigeons from the two similar calls of the Mourning Doves and Eurasian Collared-Doves. I know that most of the noise is coming from the flock of House Finches that seem to spend all their time in our yard. And that harsh screeching means the magpies have returned.

pH for Gardeners

To a gardener choosing which plants to grow, pH is an important consideration. While the pH of most soils falls somewhere between 3 and 9, the majority of common landscape plants prefer a pH slightly on the acidic side, say 6.2 to 6.8. However, some plants, such as blueberries and rhododendrons, prefer an even more acidic soil (with a pH in the 5 to 6 range) and other plants, green ash trees and clematis, for example, do best under more alkaline conditions, with a pH above 7.
