- Upon planting, mix garden soil with planting soil mix.
- Water regularly over the 1st year after planting.
- To set up a hedge with firethorn, space each plant 3 feet (1 meter) from the next.

Making cuttings in summer is the easiest and fastest option for propagating Pyracantha.
- Collect your 6-inch (15 cm) cuttings at the end of summer on semi-hardened wood.
- Remove lower leaves, leaving only the topmost ones.
- It is possible to dip the cuttings in powdered rooting agents.
- Plant the cutting in special cutting soil mix.

Pruning and caring for firethorn
Very hardy to the cold and freezing, resilient after sweltering heat, firethorn is a shrub that only needs little care, especially after it has properly settled in.
Firethorn, or Pyracantha, can be pruned in fall and/or at the beginning of spring, moderately.
- Prune lightly after the blooming to trigger branching out, which will make your Pyracantha more dense.
- Severe pruning might weaken your Pyracantha, especially against fire blight.
- If for some reason you must drastically prune your Pyracantha, best do it at the end of winter.
- Pyracantha blooms on stems grown during the previous year, so severe pruning would compromise the following year’s blooming.
Diseases and parasites that attack firethorn
The main difficulty you’ll face with firethorn is fire blight. Leaves turn brown, dry off and die within a few months.
- Nothing can be done about it, except for destroying your tree, burning it so that it won’t contaminate others.
- Luckily, some firethorn or Pyracantha cultivars have developed a resistance to fire blight.
As for parasites, it may attract legions of aphids and here is how to deal with aphids.
