Step by step: plant firethorn

Firethorn thrives in full sun or partial shade and tolerates a wide range of soils, including loam, clay, chalk, and sand, making it a versatile choice for most gardens. Choose a sheltered spot if possible, as strong winds can damage the evergreen foliage and reduce the display of berries. The plant is often grown against walls or fences where it can be trained, but it also works well as a free-standing shrub or informal hedge. Plant container-grown pyracantha in March, April, September, or October when the soil is workable and not frozen or waterlogged. Dig a hole roughly twice the width of the root ball and the same depth, loosening the soil at the bottom to encourage root penetration. If your soil is heavy clay, work in some grit or coarse sand to improve drainage. For chalky or sandy soils, incorporate well-rotted compost or manure to boost moisture retention and fertility. Space plants 50 cm apart if you're creating a hedge; for specimen shrubs, allow at least 100 cm between plants to accommodate the mature spread of 100–250 cm. Remove the plant from its pot, gently tease out any circling roots, and position it so the top of the root ball sits level with the surrounding soil. Backfill with the excavated soil, firming gently as you go to eliminate air pockets. Water thoroughly after planting, even if the soil feels damp, to settle the roots. Apply a 5–7 cm layer of mulch around the base, keeping it clear of the stem to prevent rot. If planting against a wall or fence, fix horizontal wires or trellis in place beforehand to support training. Firethorn has low water needs once established, but water regularly during the first growing season to help roots establish.
