How to Grow Candelabra Tree

Light

Water

Water deeply during active growth, then let the soil dry. Water sparingly in winter.

Soil

Use fast-draining soil and never leave the root zone waterlogged.

Temperature

Protect young plants and containers when temperatures approach 30°F (-1.1°C).

Placement

Keep away from paths and play areas because of its spines and toxic sap.

Long-Term Size

Plan for substantial height, root space and safe pruning access.

Propagation by Stem Cuttings

  1. Wear gloves and eye protection.
  2. Remove a healthy stem with a sterile cutting tool.
