How to grow Scarlet Firethorn as bonsai
Pyracantha takes full sun for best flowering and fruiting. They'll tolerate some shade, dry conditions, lime and heavy pruning. Being a vigorous grower, prune new shoots when still green and pliable. Use directional pruning and bud selection. Large garden specimens are extremely difficult to transplant so start with container stock. Prune thorns (modified branches) to encourage adventitious budding.
