Best Time to Plant in California: Why Fall Gardens Thrive

California’s Mediterranean Climate and Fall Planting

California’s Mediterranean climate makes gardening here unlike anywhere else. While most of the world experiences wet summers and dry winters, our seasons are reversed: winter is our wet season. Smart gardeners use this cycle to their advantage—planting in the fall to help new plants establish strong root systems, conserve water, and thrive with less maintenance.

How Native Plants Benefit from Fall Planting in California

California native plants have evolved to follow this rhythm. They flower in summer, drop seed at the end of the season, and wait patiently in the soil until the winter rains arrive. First, roots grow deep to capture water, and then spring warmth sparks lush top growth.

When we plant in the fall, just before the rains, we mimic this natural cycle. Once the rains begin—usually November through March—we can often turn off irrigation systems entirely. Not only does this save water and reduce utility bills, but our mild winters also mean the garden keeps growing, even while much of the country lies dormant.

Why Smaller Plants Perform Better

It’s tempting to buy larger plants for instant impact, but studies and experience show smaller plants adapt better long-term. Here’s why:

• Smaller plants establish faster. Their roots spread more readily into surrounding soil, creating a healthier foundation.

• Larger plants struggle to adapt. They’re often “pot-bound” from years in containers and can resist growing beyond that shape.

• Cost savings. Smaller plants are less expensive and, in the long run, often grow into fuller, healthier specimens.

  
  

Remember the old saying: First year they sleep, second year they creep, third year they leap. With patience, your garden will reward you.

Designing for Longevity, Not Just Looks

One of the most common mistakes I see in landscape design is overplanting. Designers (or homeowners) often pack too many plants too close together. At first, this makes the garden look lush, but it quickly leads to problems:

• Plants crowd each other out and require removal.

• Over-pruning is needed to “control” growth, which weakens plants.

• Long-term costs rise for both replacement and maintenance.

  
  

My approach is different. I design with the end in mind—using horticultural knowledge and field experience to give plants the right space to grow to their natural size. The result? A healthy, beautiful landscape that matures gracefully and lasts for decades.

Trust the Process: Fall Planting in California for Long-Term Success

A thriving California garden doesn’t need shortcuts. Plant in fall, start with smaller plants, and give them the time and space to establish. With thoughtful design and proper care, your landscape will become more lush, resilient, and low-maintenance each year.
