Assess Your Site

Every landscape is unique, and everyone is starting from a different place. Before planting or making changes, take time to understand your site and its existing conditions.

Learn what’s currently growing on your property and how it’s currently being maintained. Observe your property at different times of day and in different weather. Notice sun, shade, wind, snow, and water movement. These observations will help you make smarter choices and build a landscape that’s resilient from the start.

Check for Hazards and Requirements

Before digging or planting, call Montana 811 to locate underground gas, electrical, or utility lines. Also look for other potential hazards, such as steep slopes, unstable soils, or areas prone to erosion.

Before making changes, review your HOA’s landscaping requirements.

Identify What's Growing

Take inventory of what’s currently in your yard. Learning to identify native plants and noxious weeds is an important first step.

Noxious weeds can outcompete native plants and degrade habitat. If they aren’t managed early, they can quickly undo restoration efforts.

Helpful next steps:

Use Alpenscapes plant lists and Grow Wild’s weed ID resources to identify native plants and noxious weeds.

Understand Your Fire Risk

Map your property and identify the Home Ignition Zones around structures. Note existing plants, dense vegetation, and any materials that create direct pathways to your home.

Water Use and Sunlight

Pay attention to how water and sunlight move across your site. Your site’s sunlight, moisture, soil, and snow patterns should guide plant selection and irrigation decisions.

Do you have an existing irrigation system?
Where does water flow, pool, or run off during rain and snowmelt?
Which areas are sunny, dry, shaded, or exposed to wind
Are there noticeable temperature differences across your property?

Soil

Soil plays a major role in how water moves through your landscape and how plants establish.

Protect existing topsoil whenever possible. Healthy topsoil contains organic matter, beneficial microbes, and a natural seed bank that supports long-term plant health and recovery.

If construction is planned, stockpile topsoil first. Reusing native topsoil helps preserve organic matter and supports faster landscape recovery when soils are replaced.

Be cautious when bringing in new soil. Imported soil can introduce weed seeds or unwanted plant material, including invasive species, that are difficult to manage once established.

Ask a local landscaper or soil professional for guidance before adding amendments, especially if you’re unsure what your site actually needs.

Helpful next steps:

Soil types in Big Sky vary widely. Understanding your soil type can help guide landscaping decisions.

Sandy soils drain quickly but may not hold water long enough for roots to fully absorb it.
Clay soils hold moisture longer but absorb water slowly, which can lead to runoff or ponding if watered too quickly.
Loamy soils offer the best balance of drainage and moisture retention for most plantings.

Elevation

Your elevation can also offer helpful clues about typical soil and growing conditions:

Below 6,500 ft (Canyon): Longer growing season (90–110 days), lower frost risk, hotter and drier summers, and more sheltered from wind. Deeper soils with better moisture retention.

6,500–7,500 ft (Meadow): Moderate growing season (75–90 days), warm days, cool nights, early and late frost risk. Sunny, often dry summers. Rocky to fertile loam soils.

7,500+ ft (Mountain): Short growing season (60–75 days), high winds, intense sun, cool temperatures year-round, and possible snow any season. Shallow, rocky soils.

Snow Load

Snow piles from plowing, drifting, and roof shedding can damage plants and landscapes.

Observe where snow accumulates and design around it. In heavy snow storage areas, consider gravel, rock gardens, or hardy plants. For areas exposed to snow load, prioritize native plants with flexible branches, upright forms, strong branch attachments, or low-growing habits.

Avoid planting trees and shrubs directly below roof snow-drop zones. Leave at least five feet of clearance or use low vegetation in these areas.
