Fungus Gnat. Credit CSU Extension Service
Houseplants, especially ones that we keep outdoors in the warm season and bring back inside when frosts threaten, are likely to harbor Fungus Gnats. These tiny black flying insects (about the size of a fruit fly) can be very annoying but are mostly harmless. Adults lay 75 to 200 eggs that hatch in a week in the top 1” of soil, and when the larvae hatch, they survive mostly on soil fungi, but also feed on tender root hairs. This life cycle lasts about five weeks, although the adults only live about five days. One plant infested with fungus gnats will easily and rapidly spread the insects to nearby plants. [Read More]

Historically February is one of Colorado’s snowiest months, and finally we’re beginning to see evidence of that this year! Additionally, the forecast indicates more to come. It remains to be seen how some of our marginally hardy garden plants have suffered from the below zero temperatures.

This year the Winter Solstice will fall on Tuesday, December 21st. This astronomical event is the time of the year when the Earth’s north pole is tilted farthest from the sun, so that night is the longest and daylight is the shortest (in the northern hemisphere). This day has long been celebrated because it signals the lengthening of the days until Summer Solstice on June 21. Even though there is a lot of winter left, there will be more day light. It is the promise of Spring to come.

Our friend, Jason Kapella, an oil painter based in Hygiene, Colorado, channels over thirty years of exploration in the American West into his vibrant canvases. From footpaths to mountain boards, bikes, and fishing rods, his journey transformed into a serious dedication to painting in 2012.
Joseph Sikora was trained in a small woodcarving studio in Bavaria, Germany. He worked under the guidance of a master carver for 8 years. In 1991, he returned to the USA and opened his own business in Colorado. Joseph is active in the fields of fine art sculpture, religious art, custom furniture and architectural carving. Some of his latest projects have been to create “Old World castles & cottages” using recovered Cottonwood bark from trees in Boulder County. Joseph is passing on his knowledge through teaching carving in Boulder, Lakewood, Louisville and Westminster. He is a member of the Louisville Art Association, Colorado Carvers Club, the National Association of Woodcarvers and a founding member of the East Boulder County Artists.

Mason Bee populations plummeted throughout Boulder County due to harsh spring weather, so it’s especially important to coddle them this winter! Mason bees normally nest in holes in tree trunks, which offer stable temperature, moisture, and protection from predators. To provide extra assistance, bring your Mason and other native bee tubes/cocoons into a sheltered place with ambient (outdoor) temperatures, but with less fluctuation, like a garage or refrigerator. Cocooned bees are now adult and safe to handle in their cocoons. If you used liners or reeds, take them out of the guard tubes and shelters and store them in the fridge. Ideally, unwrap the liners/reeds and just overwinter the mason bee cocoons. Place them in a Humidi-bee chamber (in stock), and keep the lower pad moist.

Joan Hemm began working with the fabrics found in thrift-store draperies, duvet covers, tablecloths, and sheets in high school where there was no budget for costumes for the drama department’s productions. We first met Joan at a Boulder County Farmer’s Market, where she was dressed in a wonderful period costume portraying Susan B. Anthony in honor of Women’s Suffrage, and armed with voter registration forms. She had, of course, made her costume from remnants.

I turned 75 this year so I get to give some perspective on the state of the world. Here is some of the good news that is not being reported these days. I should begin by acknowledging that, oh, yes, there are lots of things that are getting worse, but many things are getting better, too.
Plants are, of course, the main thing every gardener wants in their garden. But to garden, one also needs some tools, and the quality of those tools makes a BIG difference in the comfort, ease, and speed of getting those garden chores done. Durability, reliability, precision, and ergonomic design don’t generally come cheap. A quality handsaw or pole-saw, a pair of pruning shears, loppers or hedge-trimmers will, with a little maintenance, last a lifetime.
