Growing Blackberries in Zone 9A

Blackberries are vigorous, productive cane fruits that thrive with minimal care. Thornless varieties make harvesting a pleasure.

Zone 9A has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

Top Growing Tips

• Thornless varieties (Triple Crown, Chester) are excellent for home gardens
• Train on a trellis or fence for easier management and harvesting
• Prune out old (brown, woody) canes after they fruit
• New canes grow vegetatively year one, fruit year two
• Fully black berries need 3-4 more days on vine to reach peak sweetness

Companion Planting

Good companions: tansy, garlic, marigolds

Avoid planting near: raspberries (cross-disease risk), nightshades
