How to Prune a Pyracantha Bush

Pyracantha is a genus in the large rose plant family. The several species are thorny plants often used in Christmas decorations because of their many small orange to red berries, which ripen in winter. Sometimes called firethorn, this fast growing evergreen shrub makes a good hedge or espalier because of its 8- to 15-foot height and spread. It responds well to pruning at any time of year, but if you want it to produce berries in winter, you must leave a few of the older branches on the plant.

Prune your pyracantha in winter or early spring, although it responds well to pruning at any time of year. It is helpful to prune in summer if you want to keep the plant contained. Use sturdy clippers for smaller branches and loppers for larger stems.

Cut back leggy growth to encourage the pyracantha to form branches. Cut these long shoots below the point where you want branches to form.

Snip off the tips of long, spindly shoots from time to time throughout the year. Retain some of the old branches because they will produce flowers and berries the following year.

Prune your pyracantha severely in late winter if you prefer. Use loppers to cut it close to the ground. After pruning, water your plant well by running a garden hose at a medium drip for at least 30 minutes. Fertilise with a balanced fertiliser after the soil is well-moistened.
