Getting Established

Catmint established_COS-CO_LAH_1542You’ve read the instructions; I’ve used them frequently here in my posts. “Drought resistant once established.” Sounds good—we’re always trying to save water—but how should you water these plants to start with? And what does “established” mean?

There are a lot of misconceptions about xeric plants. Our landscaper (who was much better at dealing with hardscapes than with living plants) thought that our xeric shrubs and trees needed to be sopping wet for the first few years, until they were “established.” Dead, more likely. (I’m already having to replace some fernbushes that were growing in muck, and we lost the top half of our oak tree in the first few months.)

Who Ate My Plants?

pocket-gopher-hole_colospgs-co_lah_2261Your carrots have finally reached harvestable size—you can tell from the broad shoulders slightly protruding from the soil that the crop is going to exceed expectations. Excitedly, you bend down and gently tug on the feathery green leaves. Pop! Up come the leaves and the top of a carrot—but wait! Where’s the rest? All you’re holding is a quarter inch of orange. The rest of the carrot is missing! Confused, you stick your shovel into the soil to bring up the next root, but it suddenly plunges downward, encountering no resistance. There’s a tunnel under your carrot bed. Grrrrr!

Colorful Columbine

Aquilegia hyb_Columbine_Silverton-CO_LAH_5115Envision a woodland garden, and nodding columbine are one of the first plants that comes to mind. With their intricate shapes and rainbow of colors, columbines are deservedly popular perennials.

The original North American columbine species (Aquilegia viridiflora) crossed the Bering Strait from Eurasia, migrating across the land bridge that once connected the two continents. From there, the plants expanded into new territory, evolving into new species as they moved southward. Now there are columbines adapted to every habitat from cool, high mountain meadows to burning deserts. This diversity is a boon for flower lovers; no matter where you live, there’s a columbine for your garden.

Garden Advice: Marigold Myths

Tagetes_Marigold_DBG_LAH_7897It sounds too good to be true. Not only are marigolds pretty, but growing in your vegetable garden will protect your harvest from nematodes, beetles, hornworms, whiteflies, squash bugs, thrips, hornworms, and even rabbits. I know it must be so, because I read it on the internet:

  • “French marigolds repel whiteflies and kill bad nematodes. Mexican marigolds are said to offend a host of destructive insects and wild rabbits as well.”
  • “Annual Marigolds can be used anywhere to deter Mexican bean beetles, squash bugs, thrips, tomato hornworms, and whiteflies. They are also known to repel harmful root knot nematodes (soil dwelling microscopic white worms) that attack tomatoes, potatoes, roses, and strawberries.”
  • “Marigolds also repel pests, including beetles and nematodes.”

Gee, if it’s that easy, why not? Marigolds are easy to start from seed, grow quickly, thrive almost anywhere, and produce tons of sunny yellow and orange blooms all summer long.

“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.

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.

Keeping Mosquitoes at Bay

mosquitoLast month we learned that the so-called mosquito repellent plants don’t actually keep our yards pest free. Does that mean we have to suffer annoying, itchy welts? Thankfully, there are alternatives. We start by preventing mosquitoes from breeding.

Most of us know that mosquitoes lay their eggs in water. The eggs hatch into aquatic larvae. In as little as three day (depending on the temperature), those larvae become flying adults. The males leave us alone, but the females suck up a gut full of nutrient-rich blood to support egg-laying. And often, that blood comes from us.

Fabulous Fernbush

Chamaebatiania millefolium - Fernbush_XG_20090720_LAH_7320From a distance, a blooming fernbush (Chamaebatiaria millefolium)  resembles a lovely white lilac bush, but no lilac would be in bloom at this time of year. Growing to seven feet high and wide, these shapely shrubs are covered in upright sprays of showy white flowers from June through August. Individual blossoms are reminiscent of single roses, and attract bees and butterflies. Come autumn, the flowers are replaced by russet seed heads.

A closer inspection reveals reddish peeling bark and the aromatic, finely dissected leaves that give Fernbush its common name. Even in our cold climate, these leaves stay on the bush for most of the year; branches are bare for a mere three to four months each winter. Fall foliage is an attractive copper color.
