Tierrasanta Lawn Care

Sunset Climate Zone 23 for Tierrasanta Lawn Care

The name for the community of Tierrasanta, is Spanish for “holy land,” or “holy ground”. The symbol of Tierrasanta is an encircled Conquistador cross, similar to the Montserrat Cross of Barcelona, Spain, though it holds no religious meaning. The community is referred to as “The Island in the Hills” by locals and on welcome signs. Tierrasanta, which includes numerous hills and canyons, is like an island, not directly bordered by any other community. It is bounded on the north by the Mount Soledad (52) Freeway and the sprawling southern fields of MCAS Miramar; on the east by the 5,800-acre (23 km2) Mission Trails Regional Park, which has numerous hiking and mountain biking trails; on the west by bluffs running along the wide Interstate 15 corridor running from Friars Road to Route 52, and on the south by steep canyons overlooking the San Diego River and Mission Valley.

The community of Tierrasanta is zoned Sunset Climate Zone 23. One of the most favored areas in North America for growing subtropical plants, Zone 23 has always been Southern California’s best zone for avocados. Frosts don’t amount to much here, because 85 percent of the time, Pacific Ocean weather dominates; interior air rules only 15 percent of the time. On those 15% days when hot, dry Santa Ana winds blow, Zone 23 lacks either the summer heat or the winter cold necessary to grow pears, most apples, and most peaches. But it enjoy enough heat to put the sweetness in ‘Valencia’ oranges—but not enough for ‘Washington’ naval oranges, which must be grown farther inland. Temperatures are mild here, but severe winters descend at times. Average lows range from 43 to 48°F, while extreme lows average from 34 to 27°F.
