New Photo Galleries

paradise-tanager-denverzoo-20090527-lah-236rI’d like to highlight my two new photo galleries, featuring my favorite photographic subjects: birds and flowers.

Instead of writing an article this time, I’ll let my pictures speak for me.

You will find them in the list of  links to the right side of this page. I expect to be adding more photos as I get chances to go take them, so check back every so often.

House Sparrows

You see them everywhere… singing outside your bedroom window, eating squashed bugs off your car windshield, cleaning up spilled crumbs at sidewalk cafes. They mob bird feeders full of millet and take up space in nest boxes intended for other species. I’ve even found them in a tiny town in the middle of the Utah desert, miles from anything wet or green. One would think that House Sparrows are one of the most successful species ever to populate planet Earth.

Male House Sparrow

Not closely related to North American sparrows, House Sparrows are relative newcomers to the Western Hemisphere. They were deliberately introduced during the latter half of the 19th century in repeated attempts to establish a breeding population in the U.S.

While the story is a bit foggy, apparently the birds were imported to eat insects that were damaging crops. If so, it was an egregious error. House Sparrows are primarily seed eaters, and according to one study, 78% of those seeds come from agricultural crops intended for livestock or human consumption.

Dalmation Toadflax – Linaria

linaria-toadflax-santafetrailcsco-2008oct07-lah-001More charmingly known as Butter-and-Eggs, the common name “Toadflax” applies to several similar species. All sport cheerful yellow flowers resembling snapdragons, to which they are related. Two-foot tall clumps of smooth green stems are covered with narrow, pointy leaves two and a half inches long. The flowers appear whenever growing conditions permit.

Originally imported from Eurasia as ornamentals, the plants quickly escaped cultivation and are featured on many wildflower posters. Unfortunately, Toadflaxes are now officially listed as noxious weeds. As such, it is illegal to grow them or sell their seeds.

Dwarf Periwinkle – Vinca minor

vinca-minor-xg-may142008-lah-001rs-1Appearance
With violet-blue blossoms scattered like stars across a field of emerald green, Dwarf Periwinkle is a popular groundcover in the Pikes Peak region. Also available in white and purple-red, these 5-petaled pinwheel-shaped flowers bring welcome color to a shady spot. The shiny leaves are arranged along stems that may reach three feet in length, but the plants are only six inches high. (Another species, V. major, gets much larger.) The stems will root wherever they touch the ground.

Improving Your Soil

Soil is the foundation of your garden. It pays to invest in creating the best possible soil for your plants to grow in. Living along the Front Range of Colorado’s Rocky Mountains has many benefits. However, no one would move here for the black topsoil! Instead of the optimal 5% humus content, most of our soils have little or none. It’s up to us to improve on Mother Nature.

shoveling-manure-home-plhYou can easily increase the percentage of organic matter in your soil by adding compost or another organic amendment. This added humus will act as a sponge, increasing water retention in sandy soils. On the other hand, in clay it acts to improve drainage by increasing the size of air and water spaces. Plus, organic matter works with your fertilizer by holding nutrients in a form that is available for absorption by roots. As you can see, organic matter is an important component of healthy soil.

It’s best not to add too much organic material at once. Many organic amendments are based on manure, and could contain harmful amounts of salt, as well as weed seeds. Plus, the nitrogen in fresh manure can burn tender roots. Make sure to let manures age before adding them to your garden. Decomposition requires nitrogen. Any form of organic matter that isn’t completely decomposed will steal that essential element from your plants.

Dirt

Dirt is fascinating. Oh, I know, you’re thinking of the dirt you wash out of your clothes, or off your car. I don’t find that kind of dirt very exciting at all. But the dirt in a garden is a whole ’nother story!

life-in-soil-exhibit-desertmuseumtucsonaz-2009-03-23-991rsActually, dirt is just one component of what gardeners prefer to call “soil.” Rocks weather and break down into smaller rocks, pebbles, gravel, and finally sand and silt. These tiny particles mix with organic matter—decomposing plants and animals—called “humus.” Then there’s air, and water. Add in weed seeds, worms, bugs, and a huge variety of microorganisms, and you have the living stuff in which we plant our gardens.

Peas & Carrots

Peas and carrots are a classic couple in the kitchen, but what about the garden?

Normally, peas are sown in early spring. The traditional date is St. Patrick’s Day. While that may work in gentler climes, at 7,000 ft. elevation I would need a drill to create holes in my frozen ground. I usually plant a month later, on Tax Day. At least it gives me something to enjoy on that date.

This year, weekly snowstorms have delayed all my gardening chores. I finally got my peas into the ground on May 6. I don’t have great expectations for the harvest. Maybe we’ll have a cool start to the summer, and my husband will get to enjoy his Sugar Snaps. Maybe not. That’s the gamble of gardening in Colorado.

carrots-csu-lah-058Carrots, on the other hand, are usually planted a week or two before the average last frost date. The cool temperatures and snow-damp soil help keep the seeds from drying out during the three weeks it takes them to germinate.

This year, I sowed carrots on the same day as the peas. At least they’re right on schedule. I took the time to arrange the seeds in blocks of 16 per square foot, so I won’t have much thinning to do later. In my 4 x 4 foot carrot bed, that gives me 256 carrots—plenty for our needs.

Xeriscape: Which Grass?

Now that you know why you want a lawn, and how big it should be, it’s time to consider what type of grass to grow.

Bluegrass
Lawn_UplandIN_20090615_LAH_3607Kentucky Bluegrass still reigns supreme for a turf that can stand up to hard use. It spreads via runners, so it quickly fills in holes. (But beware. Those same runners have a tendency to wind up in the adjacent flower beds.) If you have children and/or dogs, this is probably your best choice.

Flowering Crabapples

Malus Crabapple
The very cold nights we had last month, coupled with recent snowstorms, have badly damaged flower buds on crabapples and other popular spring bloomers.

Flowering crabapple trees, with single to double blooms of white, pink, or carmine, are a beautiful symbol of springtime. Varying widely in form, cultivars range from small upright trees 15 feet tall to umbrella-like specimens more than 30 feet across. Some form narrow columns; some are weeping. Many produce small, ornamental fruit that lasts all winter, in shades of yellow, orange, or red. The simple green leaves of some varieties may have a reddish cast, especially in the spring. ‘Indian Summer’ is an example having orange fall foliage. ‘Molten Lava’ has attractive yellow bark. With over 200 cultivars available, you can choose a tree that matches your site and provides four seasons of garden interest.

The Birds and the Bears

Grizzly Bear_DenverZoo_LAH_1488Last week’s news story about a local woman’s encounter with a bear while out walking prompted me to consider the responsibility we have in preventing this sort of event, which resulted in the death of the bear.

In most cases, bears approach humans because they associate us with food. As one who delights in feeding birds, I’m very aware that what I intend for the birds may also be relished by bears. While bear sightings in my neighborhood are very rare, many neighborhoods along the Front Range extend into bear habitat. We would do well to take precautions.
