Weird Spruce Growths

Coolie gall on Picea pungens @ColoCollege 2003july6 LAH 096“My spruce tree has brown things all over it! Is it sick?” The caller was quite anxious. He had a beautiful Colorado Blue Spruce growing in his yard, and now it had some sort of weird alien growths at the ends of all the branches. Was it going to die?

Over the years that I volunteered at the master gardener help desk, we would often get calls like this. No, the caller’s tree wasn’t sick, not exactly. Those prickly, cucumber-shaped growths that show up on spruces from time to time are actually galls caused by an insect. They might look peculiar, but they weren’t going to cause significant harm to his spruce.

“Rock Gardens”

Surface boulder_COS_LAH_7750In the year we’ve lived in our new house, the first on the block, we’ve gained a number of neighbors. Now that the growing season is officially underway, these new yards are being landscaped. And I’m reminded all over again of why, back in 2000, I signed up to become a master gardener.

You see, when we first moved here, I quickly noticed that the major landscaping theme was composed of lawns, junipers, and rocks. Lots of rocks. I became a master gardener volunteer to help people grow more attractive and interesting landscapes. But in spite of all that advice, apparently nothing has changed in the last 23 years.

“Bird Brain” is a Compliment!

Steller's Jay_BlkForest_20100424_LAH_3443Crows can make tools, or unzip your backpack to extract your lunch. Macaws have been known to open complicated latches their cages in order to escape their captors, demonstrating insight into complex problem solving. Jays can remember where they stashed each and every one of thousands of nuts. And I knew an African Gray Parrot that, in an effort to keep its owners home (and therefore receive more attention), mimicked the telephone’s ring every time anyone started to leave the house. In fact, many birds are exceptionally intelligent. But how do they fit those smarts into their tiny brains?

Growing Onions

Colorado State Univ. Field DayDo you grow onions? They’re not the most popular crop for the home veggie garden, which is a shame because they’re incredibly easy to grow. Sure, you can go to the store and buy a bag for a pittance, but that’s true for most vegetables we grow. And the flavor of home-grown onions isn’t that different from the ones at the market.  The primary advantage of growing your own onions is that you know exactly what you sprayed them with—or didn’t.

In general, growing onions is as easy as sticking a few sets into the ground in early spring. You can start them from seed, but they take forever to reach transplant size. That’s why many garden centers and mail order seed companies sell bunches of transplants and onion sets.

Castilleja miniata Paintbrush

Castilleja - Indian Paintbrush__SpruceGrove-Tarryall_20090626_ 0038)The scarlet blossoms really do look like bushy paintbrushes dipped in red paint; they’re hard to miss, even in a meadow crowded with wildflowers. Most of us easily identify these iconic perennials, although we may be a bit confused by the species that bloom in pink, white, and yellow.

Here along the Front Range of Colorado, the most common species of paintbrush is Castilleja miniata, more familiarly known as Giant Red Paintbrush. The one- to two-foot plant is easily identified by its long, unbranched stems lined with lance-shaped leaves. They’re topped with colorful bracts, which are usually divided into threes. These bracts are typically red (miniata means “colored red”) but you can also find blooms in shades of orange, salmon, and pink. The actual flowers are yellowish-green tubes that grow to become more visible later in the season.

Limiting Factors

2016-04-13 13.27.34

Spring has finally arrived here at 7,100 feet, and I’ve been feverishly planting—move the mulch, dig a hole, dump the perennial out of its  pot and stick it into the ground. Fill in any gaps with leftover dirt, replace the mulch. Rinse, repeat.

As I work around the lawn, adding flowers everywhere I can, I’ve noticed how abysmal my dirt is. Since we added compost, I assume that eventually it will qualify as soil, but right now I’m dealing with lumps of bentonite clay embedded in a deep layer of gritty, coarse sand. The clay was supposed to be seven feet down, but in the process of digging a basement, it got mixed  with the surface layers.

Birding Carrizo & Cottonwood Canyons

CarrizoCyn-ComancheNatlGrasslands-CO_LAH_5950

After several days of desiccating wind and heat, Sunday dawned with welcome relief in the form of much cooler temperatures and a light breeze. My trip was to the Comanche National Grasslands. I’d driven through the area years before and hadn’t been impressed. Apparently, that was because I didn’t know where to go. Oh my. I can’t wait to get back!
