Propagating Bougainvillea from Cuttings: A Step-by-Step Guide

Rooting Bougainvillea Cuttings

Bougainvillea can be propagated from cuttings, but the process is slow and requires specific conditions. Use semi-hardwood cuttings 5–9 nodes long. Take softwood cuttings when night temperatures are above 55°F, hardwood cuttings when below 55°F. Apply rooting hormone to the cut end and remove leaves from the portion that will be buried.

Critical Requirements

• Bottom heat speeds rooting (a reptile heating pad works well).
• High humidity is essential—use intermittent mist or a humidity dome; cuttings must never wilt.
• Time to root: 6–12 weeks.

After rooting, transplant carefully to avoid damaging the fragile roots, and drench with a broad-spectrum fungicide to prevent root rot.

Common Problems

Irregular flowering is often managed by drought stress. Leaf drop can result from over- or under-watering, low light, or cold. Yellowing new growth suggests magnesium or iron deficiency; treat with a micronutrient blend. Old-growth chlorosis responds to Epsom salts (1–2 tsp/gallon). Bougainvilleas have extremely fine root systems, so handle with care.
