What to Do in Your Garden in April. (Mountain)

PLANTING

* ANNUALS. Four to six weeks before the average date of the last frost in your area, start seeds indoors of drought-tolerant warm-season flowers such as coreopsis, globe amaranth, lion's tail (Leonotis leonurus), and rudbeckia. In mountain areas, start seeds of cool-season flowers and vegetables indoors this month.

* LAVENDER. Sun-loving lavender thrives in poor, dry soils. English lavender (Lavandula angustifolia) varieties are the most resilient, hardy to Sunset climate zone 2. Many hybrid lavenders are hardy to zone 3. High Country Gardens in Santa Fe (www.bighcountrygardens.com or 800/925-9387) features 11 types of lavender, including hardy pink-flowered 'Melissa' and violet-blue 'Mitcham Grey'.

* "OWN-ROOT" SHRUB ROSES. Roses propagated on their own roots are generally more weather-resistant and drought-tolerant than grafted roses. When planting, bury the bottom 3 to 4 inches of the canes in soil. Then spread a 4- to 6-inch layer of mulch on top, keeping the mulch several inches from the canes. Two good sources for own-root shrub roses are Heirloom Roses (www.heirloomroses.com or 503/538-1576) and High Country Roses (www.heigcountryroses.com or 800/552-2082).

* TREES. This year, Arbor Day is observed on April 18 in Colorado, April 25 in Idaho, Montana, and Utah, and April 28 in Wyoming. Consider planting one of these drought to lerant trees: American plum (Prunus americana), bristlecone pine, burr oak (Quercus macrocarpa), cockspur thorn (Crataegus crus-galli), curl-leaf mountain mahogany (Cercocarpus ledifolius), Gambell oak, common hackberry (Celtis occidentalis), pinon pine, ponderosa pine (Montana's state tree), and upright junipers. …
