More Basil, Please

Basil in food processor_LAH_2355The summer is winding down and my harvest (well, except for the still-green tomatoes) is in full swing. Last month I made my first basil cuttings. Now it’s time for another one. And with any luck (and a late frost), I’ll reap one more before the plants freeze.

How do I get so much basil from just a few plants? It’s not hard—I just have to plan ahead. First, I start the plants early indoors. Second, when I pick the leaves, I make very intentional cuts in specific places. And finally, I don’t let the plants go to seed. Let’s look at each of these points more closely.

Saving Rainwater

Storm moving in_XG_20090826_LAH_9762.nef

The storm pounded our garden, flattening flowers and washing away gravel. Even with the damage, I was grateful for the water—we spent over $100 last month just irrigating our xeric landscaping. Water is expensive, but rain is free. If only there was some way to save the downpour flooding our garden. But wait—there is! We could install a rain barrel!

Garden Advice: More Misconceptions

Here are three more cases where the standard gardening advice won’t do your plants any favors. (If you missed my previous posts on this topic, try typing “garden advice” into the search box at the top right of this page.)

B1 container-001Vitamin B1 stimulates root growth. No, it doesn’t. A study done in the 1930s showed that when disembodied pea roots were placed in a petri dish saturated with vitamin B1 (thiamine), they grew. From this, they concluded that pouring a vitamin B1 solution over newly transplanted plants would help them get established. However, the plants in your garden are not detached pea roots, and they’re not growing in a petri dish. Further research has shown that adding B1 does nothing to help reduce transplant shock, but it will have an effect on your wallet. If you want to encourage roots, look for a product containing a rooting hormone instead.

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.
