    Break your project into simple shapes, measure length and width in feet, and note the depth you need in inches. For a raised bed, measure the inside dimensions rather than the outside frame or you will over order by ten percent or more. Soil settles noticeably after the first few waterings, so add about fifteen percent to whatever the calculator returns.

    Finish with a three inch mulch layer to keep the new soil from crusting in the Boulder sun, and add compost each spring to keep organic matter climbing. Edging keeps your amended soil from washing into the sidewalk during a July storm.

    Frequently Asked Questions

    Click a question to see the answer

    Answer

    Do I really need to bring in topsoil if Boulder already has clay loam?

    For lawns and vegetable beds, usually yes. The native clay loam under most Boulder yards was compacted by heavy equipment during construction and stripped of its organic layer. Adding four to six inches of screened topsoil or a compost blend and tilling it into the top few inches of existing soil gives you a rooting zone that actually drains and breathes.

    Answer

    What soil should I use for raised vegetable beds in Boulder?

    A garden blend of roughly sixty percent screened topsoil and forty percent compost works well here. Straight compost dries out too quickly in our low humidity, and straight topsoil compacts. The blend holds moisture through a hot July while still draining after a hail driven downpour.

    Answer

    How do I fix drainage in my clay loam yard?

    Do not just add sand, which combined with clay makes something closer to concrete. Instead work compost and screened topsoil into the top six to eight inches to build structure, and regrade so water moves away from the house. Boulder gets most of its precipitation in short intense bursts, so shaping the grade matters as much as amending.

    Answer

    When can I start soil work in Boulder in the spring?

    Wait until the ground has dried out from snowmelt, typically mid to late April. Working wet clay loam destroys its structure and you will be fighting compaction all season. Planting warm season crops should wait until after the May 5 average last frost, though cool season greens go in earlier.

    Answer

    How much soil do I need to level a low spot in my lawn?

    Measure the area and the average depth of the depression. A 100 square foot dip that averages two inches deep needs about two thirds of a cubic yard. Fill in layers no more than an inch at a time over existing turf so the grass can grow through, and repeat every few weeks.

    Answer

    Will your soil have weed seeds in it?

    Our screened topsoil and compost blends are processed to reduce weed seed, but no bulk soil is truly sterile. In Boulder the bigger risk is airborne cheatgrass and bindweed seed blowing in from adjacent open space. Mulching over new soil and staying on top of the first flush of seedlings handles it.

    Answer

    Is Boulder soil alkaline, and does your product change that?

    Yes, Front Range soils typically run alkaline with pH in the seven to eight range, which is why iron chlorosis shows up as yellow leaves on maples and roses. Compost rich blends nudge pH down slightly and improve iron availability, but the durable fix is choosing plants adapted to alkaline conditions rather than trying to acidify the whole yard.

    Mulch Mound Pro Tip

    Never till amended soil into bone dry Boulder clay. Water the area lightly two days before you work it, then test by squeezing a handful. If it forms a ball that crumbles when poked, it is ready. If it smears, wait another day. Working clay loam at the wrong moisture level creates dense clods that will still be there three seasons from now, no matter how much compost you added.

    Mulch Mound Pro Tip

    Blend, do not layer. Homeowners often dump six inches of good soil on top of compacted clay and wonder why plants stall. The abrupt texture change creates an interface that roots refuse to cross and water perches above. Rototill or fork the bottom two inches of new soil into the top two inches of native ground so there is a gradual transition. Roots will push straight down into the native profile.

    Mulch Mound Pro Tip

    Account for Boulder's short season when you plan soil projects. With frost dates of May 5 and October 3, you have roughly 150 frost free days. Building beds in early April so soil can settle and warm before planting means your tomatoes go in on time instead of two weeks late. Fall is the other great window, since soil worked in September has all winter to mellow before spring planting.

    The Unique Landscape of Boulder

    Most Boulder lots sit on clay loam that was scraped, compacted, and graded during construction, leaving builders sand and subsoil where topsoil should be. That native clay loam holds nutrients beautifully but drains slowly and turns brick hard in a summer where rainfall totals only around 20 inches. At 5,430 feet the growing window between a May 5 last frost and an October 3 first frost is short, so roots need soil that lets them establish fast rather than fighting compaction. Bringing in quality screened topsoil or a compost blend gives raised beds, new lawns, and shrub plantings the head start they will not get from what is already in the ground. It also raises grade in the low spots where Boulder's intense summer thunderstorms tend to pond against foundations.
