Winter Planting of Aloes and Agaves in Berkeley (Zone 9b)

Go Ahead—With Conditions

If no freeze/frost is forecast, planting now is fine. Key requirements:

• Excellent drainage: amend soil with coarse sand and gravel.
• Mulch with gravel to prevent crown rot.
• Keep new plantings dry for several days after planting.
• No irrigation until established.

Species Notes

• Aloe ferox, A. striata: Winter growers—fine to plant now.
• Barrel cactus, Agave attenuata, A. cameronii: Tolerate cool temps; moisture is the enemy.
