Field guide
The Southern California landscape care calendar
Every season of the year has different challenges for landscapers in our climate — winter rain and cutback, spring pests, summer heat, autumn winds and leaves. This calendar condenses the seasonal columns our team has published into a month-by-month planning guide for property managers.
| Month | What matters | Read more |
|---|---|---|
| January | Leaf cleanup winds down; spring fertilization planning; irrigators retune controllers for low ET. | Winter Wonderland |
| February | Late-winter pruning and cultivation completed; soil stays moist — watch drainage and anaerobic low spots. | Winter cutback |
| March | Spring fertilization begins while soil is moist; trunk-injection window opens (March–April) for tree pest protection. | Spring & pest control |
| April | Pest watch: aphids emerge with tender growth; colorscape renovations get early annuals; palms fed as root activity rises. | Spring Spirit |
| May–June | Lerp psyllid main stage begins; aphid and whitefly activity climbs with warm, humid weather. | Pest control |
| July | Peak heat: balance irrigation coverage, program repeat cycles, protect seasonal color above 95 °F. | Dog Days of Summer |
| August | Hot spots peak; gypsum treatments where soil structure needs help; monitor stress before it becomes loss. | Summer notes |
| September | Early autumn prep; Santa Ana wind season opens — staking and guying equipment on trucks. | Autumn Leaves |
| October | Fall tree trimming; the year’s best turf renovation window; protect susceptible plant material from winds. | Autumn column |
| November | Leaf pickup at full volume; deep soakings leach accumulated salts; controllers step down with ET. | What’s New |
| December | Semi-dormancy: structural cutback planning; holiday walkthroughs with supervisors; water checks on containers. | Winter notes |
