How to Propagate Metrosideros?
Metrosideros can be propagated through seed sowing, cuttings, division, or tissue culture. Success relies on factors such as proper light exposure, suitable temperature, and well-draining soil. Temperatures around 20°C, along with high humidity, are ideal for the rooting of cuttings. It's important to note that seeds require stratification to break dormancy. Propagating metrosideros can be moderately difficult due to its potential for slow root development. For best results with cuttings: 1) Select healthy, semi-hardwood stems; 2) Cut into segments with at least one leaf node; 3) Dip in rooting hormone; 4) Plant in a mixture of perlite and peat; 5) Maintain high humidity and warmth; 6) Allow several weeks for rooting before potting up.
