Adding Flowers To Your Vegetable Garden By Joyce D’Agostino

Photo courtesy veggiegardeningtips.com
The spring temperatures will soon be settled and it will be safe to plant your summer garden. If you have focused mostly on growing tomatoes, peppers and other favorite vegetables, consider adding some flowers to your garden. Not only will flowers add a splash of color and interest, but they can serve a significant role in providing nectar and pollen for pollinating insects, and attracting these insects will in turn help to pollinate your vegetables.

This article is reprinted  from “Squash Bees” by Jim Cane, USDA ARS, Bee Biology and Systematics Lab, Logan, Utah. 

Got squash? If so, you have the chance to see the most important floral specialists in agriculture, native solitary bees of two genera, Peponapis and Xenoglossa, the so-called “squash bees”. Look at your squash’s flowers during the first few hours after sunrise. Male squash bees will be darting between flowers, searching for mates. By noon, they will be fast asleep in the withered flowers.

With spring marching along, it’s almost time to plant your tomato seedlings. It’s always a challenge to figure out exactly when to put them in the ground - Colorado weather is fickle this time of year. Last week’s hail storm wiped out many early planted annuals and seedlings. Once you’ve decided to proceed, follow the steps outlined in “How to Grow Your Own Tomatoes, Part 2: Transplanting, by Brian Barth, Modern Farmer. You can access the article here. Be sure to check out the links to other articles on growing tomatoes.

This article is excerpted from Leaf Cutting Bees (Megachile spp.) by Beatriz Moisset, USDA Forest Service.
There are about 242 species of Megachile bees or leaf cutting bees in North America. They belong to a larger group that includes also other leaf cutting as well as mason bees; these are all very good pollinators with very interesting habits.
Megachile bees are black and furry. They vary in size, on average about the same size as a honeybee. Most bees carry pollen in baskets on their legs. However, Megachile is different; the underside of the female’s abdomen is particularly furry and is used for this purpose. If you see a black bee, about the size of a honeybee, with a yellow belly, you probably saw a Megachile.

Dealing with Hail By Joyce D’Agostino


Hail on May 8th, photo by Joyce D'Agostino

For many of us, having to deal with hailstorms is a reality. In this area of Colorado, we are in a hail zone meaning that we can experience more than the average hail events, and some of them can wipe out your garden in minutes.

In 2009, the Denver area had a very devastating hailstorm that included powerful winds. This occurred in late July, after about 9 PM and my mature garden was shredded. Not only was this very upsetting, but it told me that in order to try to successfully garden here, that weather protection, especially from hail is a must. Just recently we had a very powerful hailstorm in this area that including very large hail so there was not only damage to cars, roofs and siding but also damaged anything that was unprotected in gardens and landscapes. Hail can happen in any season so finding some permanent solutions that can stay up year-round will help.

Pollinator of the Week: Rufous Hummingbird by Donna Duffy

Rufous Hummingbird, photo courtesy Pollinator Partnership

This article is excerpted from The Rufous Hummingbird: Small But Feisty Long-distance Migrant by Stephen Buchmann, Pollinator Partnership. 

 Many western and southwestern gardeners know the Rufous hummingbird (Selasphorus rufus) as a delightful often-unexpected visitor to colorful garden wildflowers or hummingbird feeders. These amazing small but feisty birds (only 3” long) weigh merely three or four grams; for comparison, a United States penny weighs about 2.5 grams. These birds are amazing aerialists, darting in and out, and can be relentless attackers of other birds and insects at feeders and flowers. They have long slender nearly straight bills. Their wings are relatively short and do not reach the end of the tail when the birds are perched on a feeder or nearby branches. They are also one of the few North American hummingbirds to migrate long distances. Rufous hummingbirds are a western species, rarely straying into the eastern United States.

Anyone who has tried to have a picnic, work in their yard or go camping has likely encountered the Yellow Jacket. Here in Colorado, we encounter the Western Yellow Jacket, Vespula pennsylvanica, most often. Because they are yellow and black in color, people often mistake them for honeybees, but the Yellow Jacket is much larger and from the wasp family, and can make multiple painful stings when they attack.

Pollinator of the Week: The Colorado State Insect! by Donna Duffy

Colorado Hairstreak Butterfly, photo courtesy statesymbolsusa.org

Did you know that Colorado has a state insect? The Colorado Hairstreak butterfly (Hypaurotis crysalus) was designated the official state insect  in 1996 due to the steady lobbying of 4th graders from Wheeling Elementary in Aurora, Colorado (led by teacher Melinda Terry).

The Colorado Hairstreak is a small to medium sized butterfly with a wingspan of about 1.25-1.5 inches. The upperside of the wings is purple, with a darker border; coloration is brighter in the males. Small orange spots mark the lower outside edge of each wing. The underside of the wings is light blue with faint dark bands and orange spots at the base of the hind wing. Typical of other hairstreak butterflies, a delicate “tail” protrudes from the hind wings.

Creating a pollinator-friendly garden goes beyond providing pollinator-friendly plants. Pollinators need sources of water for many purposes, including drinking and reproduction.  Butterflies, for example, will gather and sip at shallow pools, mud puddles or even birdbaths.

This information is excerpted from an article by Steve Buchman, The Bee Works. You can read the entire article here.

Moths live in a wide variety of habitats around the world. They usually go unnoticed, except when flying erratically around your porch light, a streetlight, or other light source in the darkness of night. Most moths work the night shift, unlike their “respectable cousins” the butterflies. Moths represent a biological storehouse of interesting, dramatic, and unusual behaviors, some with roles as pollinators, others as food sources.

On Earth Day, Commit to Protect Pollinators by Donna Duffy

Imagine living in a world without flowers, fruit, coffee or even chocolate for that matter. Thanks to the work of pollinators, much of the food we eat and flowers and plants we enjoy are possible. And it’s not just bees that are doing all the work. Butterflies, birds, beetles, bats, wasps and even flies are important in the pollination process. Worldwide, there is an alarming decline in pollinator populations. Excessive use of pesticides and an ever-expanding conversion of landscapes to human use are the biggest culprits.

Pollinator of the Week: Halictid Bees by Donna Duffy

In honor of the upcoming National Pollinator Week (June 19-25), we are highlighting a different pollinator every week. This week's pollinator is the Halictid bee, commonly known as sweat bees.  Thanks to Vince Tepidino, USDA ARS, Bee Biology and Systematics Lab in Logan Utah for the following information.

Pollinators have distinct foraging characteristics – some are specialists that collect pollen from flowers of just a few kinds of plants. Others, like the Halictidae (sweat bees), seem to be "anti-specialists". To paraphrase the early 20th century humorist Will Rogers, they have never met a flower they did not like, and they rarely find one whose pollen or nectar is unyielding. Such generalists visit a wide variety of flowers and often seem to do so indiscriminately. Variety seems to be the spice of their foraging lives.

Easter Lily Lore and Care by Carol King

Photo Tufts University
It’s Easter time and the ubiquitous Easter Lily is every where.  Did you ever wonder why we purchase these flowers at Easter time?  Historically speaking Easter lilies don’t have much to do with the Easter holiday.  They are not native to the Holy Land.  In Biblical lore, however, the lily is mentioned numerous times. One of the most famous Biblical references is in the Sermon on the Mount: Consider the lilies of the field, how they grow; they neither toil nor spin, yet I tell you, even Solomon in all his glory was not arrayed like one of these. (Matt. 6:28-29). Often called the "white-robed apostles of hope," lilies were found growing in the Garden of Gethsemane after Christ's agony. Tradition has it that the beautiful white lilies sprung up where drops of Christ's sweat fell to the ground in his final hours of sorrow and deep distress.

The Challenge of Growing Blueberries in Colorado by Carol King

Photo Carol King

Who doesn't love a blueberry?  They are one of the super foods, filled with antioxidents.  These tiny, round blue-purple berries have long been attributed to the longevity and wellness of indigenous natives.  Blueberries are very low in calories. A cup of fresh berries provide only 57 calories.  Some research studies suggest that these berries help lower blood sugar levels and control blood-glucose levels in type-II diabetes.  Super food indeed. Why not grow them in the Colorado Front Range home garden?

Blueberries will not grow in Colorado soil. Blueberries need acidic soil (and a lot of it).  Our native soils are alkaline; the opposite of what a blueberry needs! Every year at this time, I see the blueberry plants lined up in the big box stores just waiting for some unsuspecting gardener to purchase and take home to complete failure.

How To Plant A Tree (Video) by Carol O'Meara

Spring is the favorite time to plant trees. There are hundreds of trees at garden centers, big boxes, and give aways from cities and other tree planting promotions. Planting a tree is much more than digging a hole and if done improperly, a waste of time. This video with Carol O’Meara, Extension Agent from Boulder County advises us on proper tree planting techniques.

Rain Barrels Now Legal in Colorado

Photo by Carol King

As of Aug. 10, 2016 House Bill 16-1005 became law,  allowing most Colorado  home owners to use up to two 55-gallon barrels to collect rainwater from their rooftop downspouts. This spring appears to be a rainy one, so as a homeowner you might want to try your hand at capturing rainwater.  There are some caveats however so read the bill carefully before deciding to install barrels.

Highlights of the law are as follows:
1. Homeowners may use rain barrels to collect rainwater at single-family households and multi-family households with four (4) or fewer units.

2. A maximum of two (2) rain barrels can be used at each household and the combined storage of the two rain barrels cannot exceed 110 gallons.

3. The captured rainwater must be used on the same property from which the rainwater was captured, for only outdoor purposes, including to water outdoor lawns, plants and/or gardens.

4. Rain barrel water cannot be used for drinking or other indoor water uses.

5. House Bill 16-1005 requires the container to be equipped with a sealable lid.

6. Watering plants in a greenhouse where such a building is specifically dedicated to growing plants is NOT allowed. 

It is important for rain barrel users to understand that the capture and use of rainwater using rain barrels does not constitute a water right. The State Engineer will deliver its first report on rain barrels sometime in 2019 and if a water right holder can prove that those rain barrels have impacted their ability to receive the water that they are entitled to by virtue of their water right, rainwater collection will be curtailed.

Other considerations for the homeowner who choses to capture rainwater and use it in the landscape include the following cautions:
  • Untreated rainwater collected from roofs is not safe to drink, due to concerns surrounding microbial contamination of harvested rainwater. 
  • Because of the infrequency of rainfall there can be an accumulation of bird droppings, dust and other impurities on rooftops between rain events. Roofing materials, pitch, and heavy metals such as cadmium, copper, lead, zinc, and chromium may occur in high concentrations when it does rain. 
  • Acid rain can also cause chemical compounds to be leached from roofing materials.
  • Filtering  and screening out contaminants before they enter the storage container can help to mitigate this problem. Dirty containers may also become a health hazard or a breeding ground for insects and other pests.
For complete information on use of rain barrels in the state of Colorado, please refer to Colorado State University’s Fact Sheet. http://tinyurl.com/CSU-rainwater

The Catkins Cometh! by Carol King

I  know that spring has “sprung” when the street in front of my house becomes covered with cottonwood catkins. Our neighborhood has many cottonwoods, poplar, willows, birches and aspen trees: all catkin-loaded!  And spring is definitely here.

The catkin is is a strand of tiny unisexual flowers, blooming on many species of trees. The flowers are tiny and inconspicuous, but the blooming catkins are lovely, though very short-lived.  Catkins rely on wind to spread their pollen, and we have certainly had the wind helping out. After the female flowers are fertilized, the male catkins wither and drop.

Each species of tree has its own habits and forms, which are interesting to contemplate. The brief beauty of the catkin-bearing trees hearlds early spring, a welcome sign of greenery to come!

The word catkin is derived from the Dutch katje, meaning "kitten", because it resembles a kitten’s tail. Enjoy this brief display which hints of Springtime!

There is a growing trend among Colorado gardeners to incorporate native plants, trees and shrubs into their landscapes. Indeed, in some areas, native plantings may be required by law, covenant or policy. There are so many good reasons to include native plants in the landscape! They attract pollinators, butterflies and birds, they are adaptable to poor soil, and they typically require less water.

Happy April Fools' Day by Carol King

punjabigraphics.com
Did you ever wonder where this silly holiday came from?  Also called All Fools’ Day, it has been celebrated for several centuries by different cultures, but its exact origins remain a mystery.

 Some historians speculate that April Fools’ Day dates back to 1582, when France switched from the Julian calendar to the Gregorian calendar, as called for by the Council of Trent in 1563. People who were slow to get the news or failed to recognize that the start of the new year had moved to January 1 and continued to celebrate it during the last week of March through April 1 and became the butt of jokes and hoaxes. It became a popular holiday in 1700 in England when pranksters begin  playing practical jokes on each other. 

April Fools’ Day has also been linked to ancient festivals such as Hilaria, which was celebrated in Rome at the end of March and involved people dressing up in disguises. 

My favorite speculation and the one that is so appropriate to Colorado is the conjecture that April Fools’ Day was tied to the vernal equinox, or first day of spring in the Northern Hemisphere, when Mother Nature fooled people with changing, unpredictable weather. We have certainly have had our April Fools’  from Mother Nature!

In any event, if you receive a packet of these, dear gardener, enjoy!

Colorado's Native Bees by Donna Duffy

Leaf Cutter bee with leaf, photo courtesy dakotabees.com

Colorado has over 950 species of bees, and all but a handful of these are native. Most of the few introduced (non-native) species that now call Colorado home were brought in accidentally. The most well-known non-native bee is the honey bee, an important pollinator of many of our agricultural crops, especially those that are also non-native. But our native bees, who for millions of years have co-evolved with our native flowering plants, are much more important, efficient, and effective pollinators for native fruits and vegetables. Many of these, like squash, tomatoes, and eggplants, cannot be pollinated by honey bees at all!

Last year I was surprised to find a plant volunteering in one of my raised beds that had some unusual features, including a tall spire that had small yellow flowers. In addition it had thick and very soft fuzzy leaves. I learned that this plant is the Mullein, Verbascum thapsus. This plant goes by several common names including flannel leaf and can be found in fields, pastures, along roadsides and even in your garden.

Pre-Emergent Herbicides by Donna Duffy

Dandelion, photo courtesy extension.usu.edu
March is the time of year to consider the application of pre-emergent herbicides. Planttalk Colorado provides the following information and guidance. 

A pre-emergent herbicide does not prevent weed seed germination or kill the seed. Instead, the root system development of a young weed seedling is severely limited by the action of the pre-emergent herbicide, killing it before it “emerges” preventing the weed from establishing. Pre-emergents will not control existing weeds, but will, if applied before germination, control seedlings of annual or perennial weeds.

The Spring or Vernal Equinox by Carol King

Photo www.almanac.com
The first day of Spring brings joy to every gardener’s heart marking the beginning of the spring season in the Northern Hemisphere. 

It is the unofficial opening of the new gardening season and regardless of the weather, we’re ready! Spring arrives here along the Front Range of Colorado on Monday, March 20, 2017 at 4:29 am MDT .

There are two equinoxes every year –  March and September – when the sun shines directly on the equator and the length night and day are nearly equal.  (These are not to be confused with the soltice which also occurs twice each year in June and December when the sun is at its closest or furtherest point from the equator.)  The March equinox marks the moment the sun crosses the celestial equator – the imaginary line in the sky above the Earth’s equator – from south to north. This happens on March 19, 20 or 21 every year.
This  is called an “equinox”, from Latin (aequinoctium), meaning "equal night” and vernal (vernalis), meaning “spring”.  In reality equinoxes don't have exactly 12 hours of daylight, but close enough.

Get Your Soil Test Before You Start Planting by Donna Duffy


Most of us take our soil for granted, and don’t give too much thought about it until it’s time to plant. Even then, it’s easy to dump a bag of compost on the planting site and walk away thinking that we’ve done our soil a big favor. Not so! Soil is a dynamic living substance in which complex biological and chemical reactions take place every day. Taking time to learn about the soil in your yard is one of the best things you can do to maximize the success of your landscaping efforts.

History of the Irish Shamrock by Carol King

Photo courtesy CSU
The Irish shamrock (Irish: seamrog) is the most recognized symbol of the Irish. It has been symbolic of many things through the years. It was considered to be a sacred plant to the Druids of Ireland because its leaves formed a triad, and three is a mystical number in Celtic religion as well as many other religions. Supposedly, St. Patrick used it to illustrate the Holy Trinity to help convert Irish peoples to Christianity. 

In Ireland, all shamrocks are considered lucky and are worn and given as gifts on St. Patrick's Day. However, there is some disagreement among the Irish as to the exact plant, but most Irish growers will tell you that Trifolium repens, White Clover, is the plant most commonly known as a shamrock.   What we consider to be a common lawn weed, is a native of Ireland.  In Colorado, this Irish shamrock grows in our lawns, in prairies, pastures and foothills. If you enjoy clover honey, you can thank this lovely little plant.

Get A Head Start on Yellowjacket Control by Carol King

Yellowjacket photo by Whitney Cranshaw
I noticed wasps are waking up from their winter naps, which made me think of that old meanie, the yellowjacket.  Yellowjackets can be controlled to some extent if we start early, rather than waiting until they are buzzing around our barbecues. The traps will catch the queens before they can find a place to nest.

Whitney Cranshaw, Entomology Professor and Extension Specialist from CSU tells us that the western yellowjacket (V. pensylvanica) is, by far, the most important stinging insect in Colorado. Late in the season, when colonies may include up to 200 individuals, they become serious nuisance pests around outdoor sources of food or garbage. The western yellowjacket is estimated to cause at least 90 percent of the “bee stings” in the state. Yellowjackets (Vespula spp.) are banded yellow or orange and black and are commonly mistaken for honey bees, but they lack the hairy body and are more intensely colored. Yellowjackets typically nest underground using existing hollows. Occasionally nests can be found in dark, enclosed areas of a building, such as crawl spaces or wall voids.

Create Your Own Apple Tree by Mari Hackbarth

1909 Illustration of a "Colorado Orange" Apple,  USDA

What kind of apple trees do you think Johnny Appleseed planted as he sowed swaths of seeds to establish orchards across the Midwest?  It turns out that every seed he planted grew into a unique apple tree!  Planted apple seeds will not produce a tree or fruit exactly like the original fruit or tree the seed was collected from.  If you grow an apple tree from a Macintosh apple seed, you will have an apple tree, but not a Macintosh apple tree.  Apples are an example of a plant that can only be reproduced exactly by a technique known as “grafting”.  Grafting is the process of joining two plants together.  The upper part of the graft (the scion) becomes the top of the resulting plant, and the lower part provides the root system.

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.

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."
