overwintering rosemary, indoors and out

A quick way to clean the algae out of a garden water feature after a long, dark, and wet winter is to use a power washer. It only takes a few minutes to dislodge the long mats of algae, and the low volume of water that blows out of the nozzle doesn’t disturb even the smallest of rocks. Start at the top of where the water flows and work your way down to the bottom of the feature. This is a lot easier and more effective than grabbing the strands by hand and then using a brush to clean the rest away. You can see the difference in these “before” and “after” photos. I enjoy this a lot more than power washing the patio.

D espite our best efforts, we humans can’t do it all. Life in the 21st century often moves at a busy pace and is jam-packed with responsibilities and wonderfully abundant ways for us to spend our “free time.” While many of us love to spend a large chunk of that time enjoying our gardens, we don’t necessarily love (or have the necessary resources) to care for them. As a landscape designer, I’ve found that one of the best ways to create sustainable gardens for my clients is to develop designs that work with the sites, not against them, while also hitting on the clients’ wish lists.

Living and working in northwestern Oregon, garden designer Wesley Younie is no stranger to dealing with challenging environments. When presented with this garden’s elevation changes, drainage management, and extreme climate conditions, he devised a plan that addresses it all—along with a specific functional wish list from the homeowners. Want to know which plants he used? Here are the plant IDs for this beautiful, sustainable landscape.

Blue is not the colour you associate with foliage but if you can bend your eyes just a little around the silver – grey through to green spectrum there may be some surprises.

Do you know about the Texas State Flower? Well, it is a beautiful blooming plant with blue flowers! Read on to know all the details!

Virginia copperleaf is a tall, branched summer annual that can grow three feet tall. It takes its name from the copper colored leaves of its late summer color. This weed is a North American native that is found from Maine to Georgia and as far west as Texas and north to South Dakota. It is a member of the spurge family and is poisonous, but it does not have the milky sap that is typical of other family members. The simple leaves are oppositely arranged on the stems when the plant is a young seedling, but they change to an alternate arrangement as the weed matures.

For years, Clemson Extension personnel in South Carolina have received claims from many homeowners that they have Japanese or Asian giant hornets on their property or nesting in their homes. They have not. They have either had native cicada killers, baldfaced hornets, or the exotic European hornet. All these wasps are large, but they are not as large or intimidating as the Asian giant hornet, Vespa mandarinia. South Carolinians often use the subspecies name Japanese hornet, Vespa mandarinia japonica, but experts have merged the two as just the Asian giant hornet. Unfortunately, now some in the news media are reporting them as “murder hornets.”

They go by many common names, including horsemint and bergamot, but the common name I like the most for the plants in the genus Monarda is “Bee Balm.” Just as the name suggests, this group of plants is highly attractive to many types of bees and other pollinators and is a fantastic addition to any pollinator garden, providing an attractive flower display and nectar source through the hot summer months.

It should be no surprise to me that it was Dave who created this new online application, since besides his garden expertise, Texas-based Dave is a programmer (and the founder of Dave’s Garden, which he ran before moving on to start All Things Plants). Dave was the guest on this week’s “A Way to Garden” public-radio show and podcast, where we discussed the new Garden Planting Calendar app. (Stream the show now; get it on iTunes, or Stitcher, or at RobinHoodRadio.com.)“My wife, Trish, is actually the one who pushed me to do this,” says Dave, adding that the Garden Planting Calendar took him only two months to develop and launch. It gives you first and last frost dates (where applicable) and sowing and/or planting dates by crop, based on the location you enter.The app started with just U.S. weather data, but Canadian users quickly said, “What about us?” so Dave added that i

IT’S EITHER TIME TO HIT THE SLOPES, or hit the bar, Andre Jordan–or at least that’s how it looks from conditions as depicted in your latest doodle.

The pre-Columbian Indians of the Andes domesticated more starchy root crops than any other culture, but only the potato caught on as a staple worldwide.“The others have seldom been tried outside South America, yet they are still found in the Andes and represent some of the most interesting of all root crops.…” said a 1989 report called “Lost Crops of the Incas: Little-Known Plants of the Andes with Promise for Worldwide Cultivation” from the National Research Council.“They come in myriad colors, shapes, and sizes,” the report added. “T

I’ve never grown multiplier onions before, an oldtime favorite I pre-ordered in March from Southern Exposure Seed Exchange, which offers them for fall arrival. I haven’t found much consistent information about growing the so-called potato onions, particularly in the North, except for Southern Exposure’s fact sheet, which says to save half the bulbs for springtime planting in case the winter’s too hard for them. Sounds a little ominous, but here I go.In my cold area, I’m meant to give them up to 5 inches of soil on top of their pointed ends (only 1 inch or 2 in warmer zones), then scrape some of it away come spring, as they prefer to be closer to the surface in the growing season. As with garlic, shallots and other alliums, the bulbs want fertile, well-drained soil and a sunny location to be happiest.I’d welcome any insights or war stories if you’ve grown multiplier onions, which are also sol
