Planting Considerations

When planning your seasonal garden blooms, consider the following:

Climate Zones

California’s diverse climate zones—from coastal regions to inland valleys—affect what blooms well where. Familiarize yourself with your local climate zone using resources such as the USDA Plant Hardiness Zone Map or local gardening centers.

Timing

Timing your planting is crucial for ensuring successful blooms:

• For spring blooms, start planting seeds indoors 6–8 weeks prior or directly outside after the last frost date.
• For summer blooms, sow seeds directly into prepared beds after the risk of frost has passed.
• For fall-blooming perennials like chrysanthemums or asters, plant them in late summer or early fall for optimal blooming.

Maintenance

Regular maintenance provides optimal conditions for your blooms:

• Mulching helps retain soil moisture and suppress weeds.
• Fertilizing occasionally during active growth periods supports blooming.
• Regularly deadheading spent flowers encourages more blooms throughout the season.
