Putting Your Garden to Bed

Early fall weather brings an invigorating briskness that invites us back into our gardens. Don’t resist. There is plenty to do:

  • carrot-sleeping-in-bedSpending time now on chores such as weeding and garden cleanup will reward you many times over when spring arrives.
  • Amending your soil this fall will give you a head start on next year’s garden.
  • Fall is also a great time to build a new patio or raised bed.
  • Protecting your less-hardy plants will increase the odds of them surviving a Colorado winter.
  • Finally, winter’s cold weather is a great time to read articles, take classes, and prowl the Internet to become a more knowledgeable gardener. Your county Master Gardeners are there to help, with research-based information that is tailored to your specific growing concerns.

What Rot!

compost-piles-pbg-390Making your own compost is a great way to recycle yard waste that would otherwise end up in a landfill. It’s the epitome of green gardening, and it’s really not that complicated.

The pile should contain about half fresh, green matter (fresh manures, grass clippings, weeds, kitchen waste) and half dry brown matter (fall leaves, straw, last year’s garden). If the manure you collect locally comes mixed with straw bedding, you already have the perfect combination for compost. Mix the green and brown parts together, or create thin layers.

Shredding your ingredients helps speed decomposition. In Colorado, an unshredded pile may take several years to break down, but it will eventually turn into compost.

Digging Up Dirt

shoveling-manure-home-plh-sI keep talking about dirt. That is, I seem to have a soil fixation. Perhaps that’s because gardens begin with the soil. Properly prepared soil produces healthier plants, reducing the need for chemical sprays and fertilizer, and making more efficient use of water. Last May I discussed what soil is, and how to amend it. Today I want to expound a bit on the various types of amendments. I’ll also repeat myself a bit. That sort of thing happens as one gets older.

While living along the Front Range has many benefits, our soils are really pretty pitiful. Unless you are content growing a limited number of native plants adapted to this area, you’re going to have to improve on nature. What’s an environmentally responsible gardener to do?

In new plantings, it is worth spending a little time and money for a soil test. Knowing what your soil has, and what it lacks, helps you avoid many time-consuming and expensive mistakes. Follow the test result directions to maximize fertility and soil health. There are natural materials available to raise your levels of nitrogen, potassium, and phosphorous.

Don’t Blame Goldenrod

Goldenrod—Solidago virgaurea

Mention Goldenrod, and most people think of allergies. Yet, this showy, late-summer perennial is receiving a bad rap. The insect-pollinated flowers do not release pollen into the air. It’s ragweed, blooming at the same time, that usually causes any sniffles. Goldenrod, with its fireworks displays of yellow flower clusters, deserves to be much more appreciated.

The hardy plants range from two to four feet tall, depending on cultivar, and look best planted in groups of five or more. They prefer full sun and amended, moist soil, although they can adapt to drier conditions.  The blooms attract butterflies. Try planting goldenrod with other semi-xeric flowers such as Shasta daisies, or purple asters or coneflowers to provide a welcome contrast.

Most garden cultivars are hybrids derived from either our native species or those imported from Europe. Self-sown plants may not come true to form, so flowers should be deadheaded before seeds mature.

Green Solutions to Garden Pests

grasshopper-bf-lah-007Oh no! My organic garden is being consumed by organic bugs! Now what do I do?

Green is definitely the color of the decade, and more and more gardeners are turning to organic gardening principles for their landscapes and kitchen gardens. But what do you do when the hordes attack? Just because your harvest is in danger of premature consumption, doesn’t mean you have to abandon all your “green” principles. You are not defenseless!

Before reaching for the sprayer, consider all aspects of the problem. Chemicals, even organic ones, are only one weapon in your arsenal.

Green is for Gardens

aquilegia-caerulea-blue-columbine-cottonwood-pass-summit-15july05-lah-005“The Green Guide, National Geographic’s source for greening your life.” “Green Home—everything you need to create a healthy home environment.” Green-collar jobs, green building, and green news. Green is certainly the color of the decade. Yet, long before green became such a household buzzword, gardeners were growing green plants. Isn’t gardening the original green industry?

Gardening is a partnership with nature. Therefore, it is only fitting that we create our landscapes with an awareness of how our actions in our gardens impact the environment. Over the next few months, I plan to post a series of articles on how to garden green. Hopefully my list will inspire you to come up with ideas of your own. I’d love to hear your input.

dsc_7100Green gardening requires an understanding of ecology. What vegetation would naturally grow on this site? What stress factors do these plants need to cope with? Will the plants grow in sun or shade? Is it windy? How hot and cold will it get here?  How about yearly rainfall? Is the ground level or sloping? What is the soil like? Is it acidic or alkaline, clay or sand? What bugs or other animals eat plants in this area? Understanding how plants grow, and how they are adapted to their surroundings, lets us choose a landscape in harmony with nature.

Hand-Pollinating Zucchini

It’s time to learn about sex. Oh, you think you already know all about that? OK, but how much do you know about making baby zucchinis?

Perhaps your zucchini (or other squash) plants are producing plenty of flowers, but no squash. Or, maybe they start to grow little squashes but then the babies turn yellow to brown, get all wrinkled, and fall off. What’s wrong? It’s highly likely the problem involves zucchini sex.

All squash plants (and related crops such as cucumbers) produce two kinds of flowers, male and female. Here’s how to tell them apart:

Perennial Sweetpea – Lathyrus latifolius

lathyrus-latifolius-perennial-sweetpea-home-lah_5796Perennial sweetpea is a lovely, old-fashioned flower—one that grandmother might have grown. The keeled pea blossoms, ranging from a blushed white to a deep rose pink, form a clump atop long stems. Lanky vines sport sparse foliage. Bloom will continue from now until early fall if spent flowers are removed. If left to mature, the round, spiral pods will suddenly twist open, flinging their seeds several feet into the air, and sowing plenty of new vines in your garden.

lathyrus-latifolius-perennial-sweet-pea-home-lah-010While the more familiar annual sweet peas don’t do well with Colorado’s wild weather gyrations, this perennial form thrives here. The plants are long-lived, growing six feet long by the end of summer and then dying back to the roots in winter. They cling with tendrils, so some supportive netting is helpful.

Difficult to find as plants in nurseries, perennial pea is easily started from seed. Soak the seeds overnight to hasten germination and then plant in average garden soil in full sun to part shade. Go light on the watering.

With their cottage garden appeal, the vines combine well with clematis and roses, or you can grow them on a fence. They are also suitable as cut flowers. The only drawback is that the blossoms lack the wonderful fragrance of the annual sweet peas.

Grow a Garden of Eatin’

264-wheelbarrow-of-veggies-closeupDo all the fresh veggies appearing in the local farmers’ markets have you inspired? Victory gardens are back in style. Maybe it’s the economy. Growing your own can save you money, although your initial investment may take several years to pay off. Or perhaps you want to plant crops that are normally expensive at the market.

Gardening is good for you. You control which chemicals (if any) you use in your garden. Plus, it provides a great excuse to go outside and get some exercise.

Swallowtail Butterflies—and Parsley, Too

Like an bejeweled flower, the butterfly fluttered around my garden, never stopping to rest, moving from blossom to blossom until it gently drifted over the fence. I love watching butterflies flutter by, but feeding their caterpillars is another matter. I don’t want to sacrifice any of my garden plants to hungry mandibles. In at least one case, at least, I’ve discovered a compromise.

Black Swallowtails are some of the most beautiful butterflies found in Colorado. They’re large and black with a double row of yellow spots delineating their wings, and sapphire-blue sequins at the base of  their long, pointed tails. They’re the kind of butterfly that everyone oohs and aahs over. I’m no exception.
