Growing Blueberries in Zone 10A

Blueberries are one of the best long-term investments in any home garden. Once established, a single bush can produce for 20-30 years.

Zone 10A has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

Top Growing Tips

• Requires acidic soil (pH 4.5-5.5) — test and amend before planting
• Plant at least two varieties for cross-pollination and better yields
• Do not fertilize newly planted bushes — roots are sensitive to burn
• Net bushes when berries appear to protect from birds
• Full production takes 3-5 years, but they last decades

Companion Planting

Good companions: azaleas, rhododendrons (same soil needs), thyme

Avoid planting near: plants needing alkaline soil (lilac, clematis)

Harvest Timeline

Berries 2-3 years after planting; full production in years 4-5
