Pollinator Week: Providing Water for Pollinators

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.  

Aphids in the Garden by Bernadette Costa

As most of us have discovered, aphids are very common in home landscapes.  Sometimes called plant lice, they are small, soft-bodied, pear-shaped insects, generally less than 1/8” long.  Most are green or black but they can also be found in a variety of other colors as well.  A characteristic common to all aphids is the presence of cornicles, or tubes, on the back ends of their bodies, sort of like “tailpipes”.  These cornicles secrete substances that help protect the aphids from predators.  Over winter, aphids exist as eggs on perennial plants and hatch in the spring.

Colorado's Native Bees

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!

Welcome to the longest day of the year! Summer Solstice is June 21, 2018 in the northern hemisphere and in Jefferson County, Colorado, arrives at 4:07 a.m. MDT. The Summer Solstice is an astronomical event that happens when the sun is directly above the Tropic of Cancer. This day has more hours of daylight than any other day of the year. In the Northern Hemisphere, Solstices occur on June 20th or 21st each year.

 It is also known as Midsummer’s Day as it occurs in the middle of our summer. Summer Solstice is considered to be halfway through the growing season for gardeners above the Equator. It marks the 1st day of summer and is celebrated by various cultures, and customs around the world. Celebrating Summer Solstice dates backs thousands of years. It was celebrated by the Ancient Greeks, Romans, Egyptians, and the Celts. Summer Solstice is associated it with good harvests and fertility, and abundance in your garden.

Do you enjoy any of these foods?  Avocados, Blueberries, Apples Cherries, Chocolate, Coffee, Peaches, Vanilla?  What if you did not have them any longer?  What would your world look like then? 
Did you know that insect pollinators – primarily social and solitary bees – are responsible for pollinating 35% of the world’s crop production, increasing outputs of 87 of the leading food crops worldwide as well as many plant-derived medicines.  At least one third of the world’s agricultural crops depends upon pollination provided by insects and other invertebrates.

Rose: The Official Flower of Father's Day by Carol King

Father's Day Patio Rose
The rose is the official flower for Father’s Day and became so because of one of the founders of Father’s Day in the United States.  In 1910, Sonora Smart Dodd, from Washington State,  recognized the need for a Father’s Day after hearing a Mother’s Day sermon in church. She lost her mother at the age of 16, was reared by her father and became very passionate about the need for a Father’s Day. At the first Father's Day celebration, young women handed out roses at church, with attendees encouraged to pin on a rose in honor of their fathers– red for the living and white in memory of the deceased. Hence the rose became the official flower of Father’s Day. 
It wasn’t until 1972, during the Nixon administration, that Father’s Day was officially recognized as a national holiday.

Conglobation (Think Pillbugs): June Word of the Month

Armadillidium vulgate, common pillbug, photo courtesy

Conglobation is a term often associated with the common pillbug because of the way they roll up into a ball. This is called conglobation. Rolling into a ball is why many people call them 'roly-polies'. When pillbugs are threatened or bothered, they roll into a ball, likely to protect their soft inner body. Rolling into a ball could also limit water loss. When moving, they alternate between gradual right and left turns so that they end up moving straight forward.

Watch for Codling Moths on Apple and Pear Trees

For the first time in several years, we didn't have a late spring freeze in 2018! That's good news for fruit production in Jefferson County. The fruit trees are already showing signs of a banner fruit yield. Watch your apple and pear trees for codling moth - it's the most important insect pest of these trees in North America.  Damage is done by the larvae, which are cream-colored caterpillars that tunnel fruit and produce ‘wormy’ apples.

Spittlebugs in the Garden by Carol King

Photo Media Space
While weeding near my bee balm (Monarda), I saw several patches of a frothy white substance on the leaves. Upon further study, I discovered that I have a small infestation of the spittlebug (Cercopidae: spp) Aptly named, the white froth is what the immature spittlebug or nymphs surround themselves with as they feed on plant tissue.

Adult Spittlebug Oregon State University
Adult spittlebugs are inconspicuous, often greenish or brownish insects, about 0.25 inch long. While spittlebugs suck plant juices and can distort plant tissue and slow plant growth, they do not seriously harm plants. As they don’t cause significant damage, just wash them off with water if their appearance bothers you. Otherwise, enjoy yet another fascinating bug in action!

Cottonwoods by Carol King

The cottonwoods are starting to spit cotton. In a few days the skies will be filled with cottonwood snow. It will pile up in the corners of the porch and cover the spirea bush like cotton candy. People’s noses will itch and they will blame the cottonwood. The cotton will stick to your sweaty body as you garden and you will go into the shower looking like a giant spider tried to snare you. Invariably, the call comes in for help. Can’t we do something? Please!

A combination of factors causes these trees to produce abundant seed. Sometimes large seed production is a reaction to stress (drought), while other times it is caused by favorable moisture. In other words, they just do this.
The cottonwood at first glance and without proper study, can easily be dismissed as a "trash tree." It has some personal habits that the urban homeowner can find extremely irritating. Like the male catkins that fall early in the spring looking a little like hundreds of wooly worms on the ground. And the sticky pods that fall after that and stain your pants. Then the female lets loose with this cotton, and then because it self-prunes, there are always twigs and dead leaves beneath the tree.

But before we dismiss the cottonwood let’s consider its place in history. I think a very good case could be made for us not even being here without the cottonwood. It provided the Native people shade, a place to camp for the night, and they used the inner bark for women's skirts; the European settlers used the wood for their cabins and their coffins. The Mexican and Spanish people of the Southwest
used it for fuel, its life-saving shade and its roots for carving religious icons. I like to think that the cottonwoods along our ditch are relatives of the ones the Arapaho Chiefs Little Raven and Left Hand shaded themselves under long before Denver began, when they camped along Cherry Creek near its junction with the South Platte.
The rustle of the leaves of the cottonwood can remind you of lapping or rushing water. And last fall right here in the wilds of north Lakewood, a group of vultures migrating, roosted overnight in the neighbor's cottonwood wowing us all with the sight of those great dark birds perched in the tree.

There are a lot of them in north Lakewood (cottonwoods, not vultures), partly because of the irrigation ditches that continue to meander through parts of Jefferson County from a throw back time when this was farmland. And as the cottonwood chooses its own spots it grows all along the irrigation ditches.
So in answer to that question, what can I do about the cotton from the cottonwood? Well, nothing, short of cutting all the trees; or spraying every tree every year with a growth regulator. Ethephon, sold as Florel™. It is labeled to prevent cotton development in female trees and needs to be applied during flower development.

I would like to propose a new reverence for this tree; an understanding that the benefits outweigh its trashiness. Birds call it their home: the woodpeckers, the owls, the grackles, the magpies and vultures; and it continues to offer us life saving shade and the lovely sound of water when the wind blows. And perhaps we should ponder whether our lives have to be so tidy that we don't allow some messiness to interfere?

I say, consider that cottonwood an embarrassing old aunt of a tree. She dresses all wrong, talks too loudly, but has a heart of gold. Her skirts are too short, she gets drunk at Thanksgiving dinner, but she will give you her last dime and a bed on her couch for as long as you need it. She deserves your love! Celebrate the cottonwood. Gather the cotton and stuff a pillow; the cotton is actually hypoallergenic!

Fall is Not the Only Time to Plant Bulbs by Carol King

As you are planting  your summer flower garden, don’t forget to include bulbs, corms and roots. Some examples include gladiolus, dahlias, canna, lilies and tuberous begonias. Often called summer bulbs, these flowers add an exotic touch to the garden. Here are some of the most popular examples:

Photo Pine Tree Garden Seeds
Gladiolus is a popular corm, coming in nearly every color, including lime green. Plant the corms 3 inches deep and 6 inches apart in the spring, after danger of frost has passed. During the growing season, the original corm withers and a new corm forms on top of it. The cutting of the flowers does not inhibit the development of the new corm, as long as the leaves are left. As soon as the vegetative top of the plant dies down, dig the corms. Remove the withered corm, and store the new corms in a frost-free location over winter. Avoid a storage place with high temperatures and low humidity.

Dahlia Show Everett, Washington
Dahlias come in a wide variety of colors. They usually require support because of their height. Provide support by driving a stake into the ground 12 inches deep and 6 inches behind the root at the time of planting. Dahlias do not tolerate frost, so plant the tuberous roots after all frost possibilities have passed. In the fall when the vegetation is killed by frost, prune back the stalks to 6 inches. Leave the tuberous roots in the ground for two weeks to harden before digging them.  Dry the tuberous roots enough to shake off excess soil, and pack in sawdust, perlite or vermiculite and store in a cool, dry place until spring.
