A terraced hillside garden at golden hour. Three dry stacked sandstone walls step up the slope, slab steps climb through them, and grasses, sage and penstemon grow between. The Flatirons sit hazy behind.

The working year

Through the seasons

A dry garden at 5,430 feet keeps its own calendar. This is what we do, and when, and why it cannot wait.

  1. MarAprMay

    Spring

    • Cut back last year's grassesMarch, before new growth shows
    • Turn on the drip and test every zoneLate April, once nights stay above freezing
    • Plant perennialsAfter Mother's Day, when the last frost has passed
  2. JunJulAug

    Summer

    • Build walls, steps and patiosDry ground carries stone and machines
    • Water new plants deep, twice a weekEarly morning, never a daily sprinkle
    • Weed first year beds by handUntil the natives close the gaps
  3. SepOctNov

    Fall

    • Plant trees, shrubs and grassesWarm soil and cool air. The best window of the year
    • Sow native meadow seedNovember, so winter can do the work
    • Blow out the irrigationBefore the first hard freeze, by mid October
  4. DecJanFeb

    Winter

    • Draw the plans for springBare ground shows the true shape of a slope
    • Prune trees while they sleepJanuary and February
    • Water evergreens in dry spellsAny week above 40 degrees with no snow cover

Water, all year. Every garden we plant runs on drip. A native bed drinks about a third of what the lawn it replaced did, and after three summers most of it needs almost none.

Drawing, all year. Site visits and measured plans do not stop for snow. A plan drawn in January is a garden planted in May.

How a project runs

Four steps, one crew and a drawing you can hold us to. The plan here is the one we drew for the Marlowe terraces, the garden at the top of the page.

  1. Site visit

    Ines walks the ground with you for about ninety minutes. Slope, sun, soil, drainage, and where the deer come through.

    $180, credited to your design

  2. Measured plan

    A plan drawn to scale, a plant list by Latin and common name, and a fixed price for the build. Two rounds of changes are included.

    Three to four weeks

  3. Build

    Our own crew of six, led by Tobias. Grading and walls first, then irrigation, then plants. We never hand the stonework to anyone else.

    Three to seven weeks on site

  4. First year care

    Three visits in the first year. We tune the drip, replace anything that fails and leave you a watering calendar.

    Stonework guaranteed five years, plants one

What it costs in 2026

Ballpark numbers. Most finished gardens land between $28,000 and $140,000, and every build is quoted as one fixed price before a single stone is moved.

Measured plan and plant listfrom $2,400
Dry stacked wall, per face foot$95 to $140
Flagstone patio, per square foot$38 to $52
Native planting with drip, per square foot$14 to $22

Is there a minimum project size?

Design and build projects start around $28,000. Smaller planting jobs we take in fall, when the crews have room.

How long until work starts?

Usually three to five months from the site visit. Stonework is booked first and planting follows the season.

Will the garden need watering?

For the first two summers, yes, on a drip line we install. After that most of it lives on rain.

Do you look after what you build?

The first year is included. After that we offer two visits a year, in spring and fall.

Can you work with my homeowners association?

Yes. We draw the plan to their rules and file the paperwork.
