Is this the year you’ve decided you’ll spend more time on flowers and vegetables and make that boring expanse of lawn more colorful and edible? Here’s how to start.

Find the sun

Find where the sun shines on your yard and where the shadows are. This is the very first and most important step you must take. If you didn’t notice last year, you can estimate.

See where the shadows of currently leafless trees fall during the day. Find the sunny, south-facing side of your house.

For vegetables you want the sunniest location possible, at least 6 hours of full, summer sun. Do you have overgrown or dying trees and shrubs that need pruning or removal? However, a little shade by late afternoon keeps veggie leaves from temporarily wilting.

Keep vegetable gardens close to the house so it is easier to step out and pull the occasional weed and pick the ripe tomatoes.

Flowers aren’t as picky about sun because there are kinds suited to different light levels: sun, part sun, part shade and full shade. If you desire to grow a certain kind, google its light requirements.

Block the wind

In most residential neighborhoods there are enough obstacles, houses and landscaping, to blunt the wind. But if you are out on the prairie, you might want to put delicate plants in the lee of the barn or plant a windbreak first.

Get the dirt

Soil is anything a plant can stick a root into.

Good soil for vegetables (and other annuals) has lots of microorganisms that help feed the roots. Most vegetables are big feeders. They use lots of nutrients, so you’ll want to dig in compost the first year and then add layers of leaf/plant/kitchen compost mulch after that as needed. No need to dig again in future years.

If you use chemical fertilizer instead (unfortunately limiting good soil microbes), remember to follow the directions. Too much nitrogen gives you leaves and no fruit and too much of any fertilizer gives you sick or dead plants. And remember, Cheyenne has alkaline soils so do not add alkaline amendments like lime and wood ash.

Perennial plants rated for our zone 5 or colder (Zones 3 and 4), especially native plants, are really quite happy with whatever soil is available. If you are trying to grow flowers in the equivalent of pottery clay, gravel pit or sandbox, you might look for native species adapted to those kinds of soil. Or consider growing your plants in a raised bed or container you can fill with better soil.

Water carefully

Here in the West, water is a precious commodity so save money by not throwing it everywhere. If you have a sprinkler system, make sure it isn’t watering pavement.

The new era of home landscaping encourages us to replace our lawns with native perennials because they use less water. Native plants also provide food for birds, bees and butterflies, and habitat for beneficial insects. The Cheyenne Board of Public Utilities is installing a demonstration garden at its headquarters this spring.

But you will need to water a new perennial garden regularly until it gets established, and at other times, so figure out how far you want to lug the hose or stretch a drip irrigation system.

Once established, a native perennial garden not only takes less water than a lawn, but it doesn’t require the purchase of fertilizers, pesticides or gasoline for the mower. Your time can be spent admiring flowers instead of mowing. Although if you convert a large lawn to a meadow, you may want to mow it once a year.

Vegetables are water hogs. The fruits we harvest, especially tomatoes and cucumbers, are mostly water. Unless you like to contemplate life while watering by hand, check out drip irrigation. You can even put a timer on the system.

Sprinklers, on the other hand, waste a lot of water, especially when it evaporates in the heat and wind before it can get to the plants. If you abstain from watering between 9 a.m. and 5 p.m., you’ll lose less to evaporation.

Deleting lawn

While you can rent a rototiller to open up an area for planting, I prefer to use a sharp spade. I dig one clump of grass at a time, only about 8-10 inches deep, break and shake off as much soil as possible and put the remaining chunk in the compost bin—or fill in a hole in the remaining lawn.

It’s slow going, but I disturb fewer tree and shrub roots that underlay my entire yard. When I get tired of digging, that means I’ve reached the amount of new garden I have the energy to plant this year. I don’t want gardening to become a chore!

The plants and details

In the six years I’ve been interviewing local gardeners and writing monthly columns, I’ve accumulated a lot of information, from seed starting to native grass lawn alternatives to growing giant pumpkins and native perennials.

Garden Site Preparation

Wide bed

Wide beds maximize limited garden space.

Published April 22, 2012 in the Wyoming Tribune Eagle, “Getting the dirt on garden prep: A green and growing garden in summer begins with preparation–now.”

The unusually warm and dry weather in March created perfect conditions for early digging in the garden, dry, thawed soil. Usually, early spring means wet or frozen soil and digging in wet soil will destroy the structure.

My husband, Mark, was anxious to dig out the stump of the spruce we had removed because it outgrew our yard. We never limbed it so the spruce’s skirts nicely shaded out the grass underneath. So after removing the stump and shallow roots, we have the perfect space for a new garden. It’s also good timing since I have a lot of seedlings started, as you know from reading last month’s column.

How do you select a site for your new garden? Consider these factors: light, water, size and, especially if you are planting vegetables, distance to the kitchen.

Light

A vegetable garden needs five or six hours of sun daily, preferably morning sun–not the scorching rays of summer afternoons. If you are growing flowers, you can choose varieties suited for just about any proportions of sun and shade.

Because our growing season is so short, you may not want to choose a site where the snow lingers, as it will take longer for the soil to warm.

Size

The size of my new garden was dictated by the footprint of the spruce. It’s 11 by 14 feet, manageable for a first effort at growing vegetables and annual flowers.

Distance to kitchen

If the vegetable garden (or any garden) isn’t close to the kitchen, it won’t get the daily inspection that leads to success, said Catherine Wissner, University of Wyoming Cooperative Extension horticulturist.

I may “neglect” standard garden practices such as rototilling and spraying weed killer, but I don’t neglect to enjoy visiting my perennial garden often, pinching the occasional bad bug or pulling a tender young weed.

Water

Distance to water is important—how far are you willing to drag the hose? Can you set up a drip irrigation system?

Revealing the dirt

You could kill grass using chemicals such as Roundup if you are extremely good at following directions. Another option is to stake clear plastic over the turf for a few weeks, allowing the intense heat of the sun to kill off the grass and weeds.

Digging up turf with a sharp spade takes less time, though it’s hard work. One advantage is it will keep you from making your garden too large in the first year. If you are careful, you can use the spade-sized chunks to fill in bare spots elsewhere, or knock the dirt off and compost the remains.

Fixing the dirt

Every gardener believes that his or her soil could stand improvement. I believe enough compost added over time can redeem almost every soil type.

Cheyenne’s default soil is clay-like, making it difficult for plant roots to grow and draw water. Local gardeners overcome this by digging in compost–partially decayed plant material–to a depth of about two feet. Mark did just that for our new garden, using the leaves from our trees that served as protective mulch for my perennials over the winter. Adding more to the top few inches every year eventually makes for loose and fluffy soil.

A word of advice: Check for underground utilities before digging in your yard. All it takes is a simple call to 811 (www.call811.com).

Compost is available commercially in bales. It’s also available from the City of Cheyenne’s compost facility at 3714 Windmill Road; hours are Monday through Saturday, 10 a.m. – 6 p.m. and Sundays, noon to 4 p.m.).

A word of caution: Be sure the compost doesn’t contain residual herbicides. Using livestock manure in a vegetable garden is tricky. Unless it is composted at high, even heat, it could transmit pathogens, such as salmonella, to people consuming the crops. And it is possible to apply too much and burn plants.

My experience is that composted leaves and grass will improve soil structure—and encourage the soil microorganism community to flourish, acting as a low dose of fertilizer.

If your plants have failed to thrive in the past or you are curious about the fertility of your soil, you may have it analyzed by experts who can tell you what kinds of amendments might be needed, and how much.

Colorado State University has a soil testing lab. Call them at 970-491-5061 or visit www.soiltestinglab.colostate.edu. The routine test is around $30.

Remember, our soil here, with few exceptions, is alkaline, not acidic as it is back East, so don’t add wood ash and limestone.

Digging the dirt

If you do a good job of digging a new garden, you shouldn’t have to do it again. Obviously, perennial gardens don’t get rototilled every year. Mine receives a top dressing of leaf litter annually because I don’t sweep the soil surface clean (another instance of my gardening by “neglect”). Many perennials are native to less than perfect dirt anyway.

But what about my plan to grow annual flowers and vegetables from seed this year–and perhaps years to come? Will I have to convince Mark to dig as deeply again next spring, or get a rototiller?

I won’t, if I take the advice of Eliot Coleman, an organic market gardener in Maine and author of the book “Four-Season Harvest.” After the initial dig he amends only the top few inches each year. That way soil structure isn’t destroyed. Also, the less you disturb the soil, the fewer weed seeds sprout.

Wide bed method

Shane Smith, director of the Cheyenne Botanic Gardens, is also a soil protectionist. He is a proponent of wide beds rather than planting vegetables in traditional rows. Plants are set in short cross rows or staggered, depending on the space they need.

Somewhat like establishing raised beds, minus the boards to contain the soil, each bed is as wide as you can comfortably reach, maybe 3 feet. A 2-foot-wide footpath between beds means you never walk on the beds themselves, preserving the fluffiness of their soil (roots need the air), and you never have to waste time and money improving the soil of the pathways. For more information, pick up a pamphlet at the Gardens or visit online at www.botanic.org.

Coming up

Next month, I’ll look into best practices for transplanting, direct sowing, and picking out plants at the nursery. If you need to transplant your starts into bigger pots, remember to hold them by their leaves only, to avoid crushing their stems—they can always grow a new leaf, but not a new stem.
