The boxwood (buxus sempervirens) is an evergreen bush prized for its foliage and great ease of use. Unfortunately, it is now falling victim to numerous pests and diseases, the most dreaded of which is the Box Tree Moth.

The box tree moth (Cydalima perspectalis) is a small defoliating caterpillar that wreaks havoc on the bush. Originally from Asia, this caterpillar, which later transforms into a harmless moth, mercilessly devours large quantities of boxwood in gardens as well as in the wild. In this advice sheet dedicated to the Box Tree Moth, we share our tips for combating this pest.

Additionally, box blight, a fungal disease caused by fungi (Volutella buxi or Cylindrocladium buxicola), also causes significant damage in gardens.

Given the challenges now posed by boxwood in the garden, the solution is to replace boxwood with other alternative bushes that, like it, are evergreen, lend themselves well to repeated pruning, and show good resistance to pests and diseases. These bushes can be used for low hedges, topiary, and even in pots on a terrace. Discover our selection of bushes that make excellent alternatives to boxwood.

Crenate hollies or Japanese hollies
Spindle bushes (Euonymus fortunei, E. japonicus)
Shrubby honeysuckles (Lonicera nitida, pileata)
Burkwood osmanthus

Ilex crenata are excellent candidates to replace boxwood. Indeed, the resemblance is striking with their similar evergreen foliage. They thrive in sun, partial shade or full shade depending on the variety. As for soil, they require humus-bearing, fresh and light earth. However, they dislike excessive lime content. An important detail to note: unlike their cousins, they are thornless! Very hardy and slow-growing, they tolerate pruning extremely well: one annual pruning in early spring suffices. Depending on the variety, they can be shaped into low hedges, topiaries, cloud-pruned trees (Niwaki) and even bonsai. Note that the ‘Green Hedge’ variety is a perfect alternative for low hedges – simply plant them 40 to 60 cm apart. They can also be grown in containers on terraces.

Certain spindle bushes can brilliantly replace boxwood. Euonymus fortunei and japonicus are particularly well-suited, and if you love variegated foliage, this alternative is perfect for you! Euonymus fortunei, hardy down to -15°C, thrive in all soil types including lime-rich soils, provided they’re fresh and well-drained. Plant them in sun or partial shade. Their rapid growth also makes them excellent ground cover. Euonymus japonicus, slightly less hardy (-12°C) but taller, prefer less lime-rich soil and sunny positions sheltered from cold winds. Evergreen, they tolerate repeated pruning well and form dense bushes suitable for topiary or low hedges. Two annual prunings (spring and autumn) maintain a compact habit. For low hedges, space bushes 60 cm apart.

  • African Box (Myrsine africana)

Myrsine africana is also an excellent candidate to replace box in Mediterranean regions. Indeed, it’s best suited to warm, dry climates. It can withstand long periods of drought but only short spells of frost (-10/-12°C). It thrives equally well in sun or shade and isn’t at all bothered by limestone soils. This evergreen bush has small, glossy, ovate green leaves, with younger leaves appearing lighter in spring. Be aware that it may take some time to establish. With slightly faster growth than box, it also responds very well to pruning, making it ideal for hedges, topiary or container cultivation. Plant bushes 40cm apart and prune two to three times a year: in March, June and September to form a low hedge.
