If you’ve recently moved to the San Luis Valley or you’re looking at a property with some acreage, you’ve probably already realized that gardening in the high desert is a completely different beast than it is at sea level.
Up here in Alamosa and the surrounding high country, we’re dealing with a short growing season, intense UV rays, and soil that can be... well, let’s just call it "challenging." But don't let that discourage you! A well-landscaped mountain home not only boosts your curb appeal but also makes those cool summer evenings on the patio that much sweeter.
Here are a few "insider" tips for successful high-altitude gardening:
1. Know Your Last Frost Date (And Then Wait a Week)
Down in the valley, we can have a beautiful 70-degree day in May, followed by a surprise snowstorm that night. Generally, the "safe" window for planting starts in late May or early June. If you're eager to get started, stick to cold-hardy greens like kale, spinach, or peas that can handle a light dusting of snow.
2. Sun Protection Isn't Just for You
At our elevation, the sun is significantly more intense. Even "full sun" plants from a big-box store might struggle with the UV levels here.
- Tip: Look for "Mountain Hardy" labels at local nurseries.
- Strategy: Use afternoon shade to your advantage. Planting on the east side of your home can protect delicate flowers from the scorching 2:00 PM sun.
3. Wind is the Silent Garden Killer
The wind across the flats can dry out a garden faster than the heat. If you’re building or landscaping, consider:
- Windbreaks: Fencing, rock walls, or a row of hardy shrubs like Serviceberry or Caragana.
- Mulch, Mulch, Mulch: A thick layer of wood chips or gravel helps keep moisture in the soil where it belongs.
4. Focus on Native Perennials
· If you want a garden that thrives with minimal fuss, go native. Plants like Blanketflower (Gaillardia), Rocky Mountain Penstemon, and Blue Flax are built for our climate. They’re drought-tolerant, love the sun, and—best of all—they come back every year without you having to lift a finger.
5. Container Gardening is Your Best Friend
· If you’re worried about the soil or the unpredictable weather, start with containers. They allow you to control the soil quality perfectly, and if a late-season frost is forecasted, you can simply tuck your pots into the garage for the night.
·
If you live in an area where the wild horses or other hooved animals live though, you’ll be smart to enclose the containers in fencing, otherwise, you are making their snacking easier.
· Real Estate Pro-Tip:
· Properties with established, low-maintenance "Xeriscaping" (landscaping that requires little to no irrigation) are incredibly popular right now. It saves the homeowner money on water bills and looks beautiful against our rugged mountain backdrop.
