Tulips Emerging Early by Donna Duffy

This recent surge of warm weather has created conditions for some spring-blooming bulbs to emerge early. You’ve probably noticed crocus blooming, especially if they are near a wall or rock. Crocus are tough, low-growing flowering bulbs, and can tolerate snow and cold. I also noticed that some of my late-season tulips  have just broken ground, and that is more unusual. Here are some tulip tips for late winter from Ron Smith, Horticulturalist at the North Dakota State University Extension Office.

How Insects Overwinter by Mary Small



Bees Huddling to Keep Warm, photo courtesy CSU Extension

All insects have developed strategies for surviving the winter.  Some migrate to warmer climates, but most stick around.  How do they do it? 

Honeybees really do huddle together…in a ball, with those on the outside of the ball (acting as insulators) gradually exchanging places with the bees on the inside of the ball. The bees on the inside of the ball generate heat through shivering. No helmets or jerseys, though.

As the days slowly get longer, many of us start thinking about our planting beds for the next growing season. The use of paper-based sheet mulch has gained attention. But is it effective? Linda Chalker-Scott, Ph.D., Extension Horticulturist and Associate Professor, Puyallup Research and Extension Center, Washington State University, is known for her myth-busting horticultural research.

Try Amaranth in your Garden by Vicky Spelman

Matthew Blair, Researcher at Tennessee State University in a Field of Amaranth

If the popularity of quinoa has taught us anything, it's that people are increasingly open about exploring grains besides the familiar wheat and rice. Now, researchers at Tennessee State University are hoping consumers are ready to give another ancient grain a try: amaranth.

Amaranth was revered by the Aztecs in Mexico. Today in the U.S., it's mostly grown in people's backyards or on research farms, like an experimental field at Tennessee State University.

Some of the amaranth there looks like corn with a colorful, flowery plume on top. Others are more like shrubs. Matthew Blair, an associate professor at TSU, is leading a team of researchers in evaluating dozens of varieties.  Amaranth is a grain that thrives in high temperatures, is largely resistant to drought and is seen as a heartier crop than corn.  "We all know how fast corn grows in the summertime," Blair says. "Well, amaranth can grow equally fast, or faster."

Here They Come...Seed Catalogs! by Donna Duffy

It's the stuff gardeners' dreams are made of: seed and nursery catalogs that fill our mailboxes in January and put us on the road to planning our next garden. Those catalogs are a lot more than a list of products the seed companies want to sell. They are encyclopedias of information that, among other things, tell us which plants won't grow in Colorado. That keeps us from throwing away money for plants destined to fail with our growing conditions. Dan Jewett, Denver County Master Gardener, offers the following information to get the most out of the seed catalogs that end up in your mailbox.

Nature's Beauty: Hoarfrost by Donna Duffy

Sometime this winter, you may be fortunate enough to see hoarfrost in your landscape. But look quickly, because it will disappear with sunlight.

According to the Old English dictionary (c. 1290), hoarfrost is defined as "expressing the resemblance of white feathers of frost to an old man's beard." No, this isn’t frost on performance-enhancing drugs, but it can be quite different from your normal frost! Colleen Hart of The Weather Channel provides the following facts about hoarfrost.

Symposium Sneak Peak: Companion Planting by Dustin Foster

Separating the facts from fiction when it comes to companion planting can be tricky.  There are many “old wives tales” and practices learned from grandparents and parents.  Some actually, if not accidentally, have some scientific truth to them and some, not so much.  Once such scientific concept is called trap cropping.  Although it may not have been known as that back in the day, it is a scientifically proven companion concept.
