Expert tips
The key tip
Nettle tree establishes best in deep, loosened, well-drained soil. Water young plants especially during dry summers.
The common mistake
Planting too deep or keeping the collar wet encourages trunk base problems.
The pro's trick
Mulch generously but keep the collar well clear.
Care
Watering
Once established, the nettle tree is very drought-tolerant thanks to its deep root system. During planting or prolonged dry periods, water regularly in summer, especially young specimens. Favour deep watering rather than light, frequent watering.
Exposure
Install the nettle tree in full sun for best growth and optimal fruiting. It tolerates light shade but will develop a less compact habit. South or west-facing exposure is ideal in temperate climates.
Soil
The nettle tree adapts to all soil types, including chalky, poor or compacted ground. It mainly fears prolonged waterlogging. Well-drained soil is preferable, but the tree tolerates aridity once established.
Pruning and thinning
Prune lightly in late winter to maintain good structure. Thinning can be done without risk in February-March. Remove dead or crossing branches. The nettle tree tolerates pruning well and recovers quickly.
Fertiliser and nutrition
Undemanding, the nettle tree generally requires no regular fertilisation. During planting, incorporate well-decomposed compost. A balanced fertiliser application in spring can speed up growth in young trees.
Diseases and pests
The nettle tree is particularly hardy against pests and diseases. Only dieback due to waterlogging or very cold winters can be problematic. Aerate the soil and ensure proper drainage to prevent any fungal issues.
Did you know?
The nettle tree was greatly appreciated by children in southern France who harvested its small sweet fruits resembling black berries. In Provence, this tree was often planted near dwellings or pathways for its ornamental and nutritious qualities. Its hard, resistant wood was long used to make tool handles and turned objects.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
