Why Fall Landscape Preparation Starts in September in San Diego

September may not feel like fall in San Diego, especially in East County, but your landscape is already beginning to transition. While temperatures can remain high, shorter days and changing plant growth make September an important time to prepare your property for the months ahead.
September Is Still Hot, but Your Landscape Is Changing
Unlike many parts of the country, fall landscaping in San Diego doesn’t begin with cold temperatures and falling leaves. September can still bring significant heat, which means plants may be recovering from months of summer stress while still needing adequate water.
This makes September a good time to evaluate your landscape for signs of stress, damaged growth, dry soil, or areas that struggled during summer.
It's Time to Revisit Your Irrigation
As daylight hours shorten and temperatures eventually begin to change, your landscape’s watering needs will change too. Keeping the same irrigation schedule throughout the year can lead to unnecessary water use or improper watering.
Checking irrigation coverage, repairing problem areas, and adjusting schedules helps prepare your landscape for fall without sacrificing plant health.
Prepare Now for Fall Planting
September is also the time to start planning fall landscape improvements.
Before adding new plants, consider the condition of your soil, existing irrigation, sun exposure, and how much space plants will need as they mature.
Soil conditioning can also help prepare planting areas by creating a healthier environment for roots before new plants go in.
Look at the Bigger Picture
Good landscape maintenance in San Diego is about more than responding to what you see today. September provides an opportunity to evaluate how your property handled summer and determine what should be adjusted for fall.
