London Plane in November: monthly care

London plane is a large, vigorous tree best suited to parks, wide avenues, and spacious gardens where its eventual size—20 to 35 metres tall and 15 to 25 metres wide—can be accommodated. Plant bare-root or container-grown specimens in October, November, or March, when the tree is dormant and soil conditions are workable. Avoid waterlogged or frozen ground. Choose a position in full sun with plenty of space for the crown to develop without interference from buildings or overhead cables. London plane tolerates a wide range of soil types, including clay, loam, and sandy soils, and copes well with urban pollution and compacted ground. Prepare the planting hole to roughly twice the width of the root ball but no deeper; the root flare should sit level with the surrounding soil surface. Break up compacted soil at the base and sides of the hole to encourage root penetration. Position the tree, backfill with the excavated soil, and firm gently to eliminate air pockets. Water thoroughly after planting—apply at least 20 litres to settle the roots. Drive in a sturdy stake at a 45-degree angle to avoid damaging the root ball, and secure the trunk with a tree tie, leaving room for growth. Apply a 7–10 cm layer of organic mulch around the base, keeping it clear of the trunk to prevent rot. Water regularly during the first two growing seasons, especially in dry spells, to help the tree establish a deep, resilient root system.

London plane requires minimal pruning once established, but formative pruning in the early years helps develop a strong framework. Prune during dormancy in November, December, or January to reduce sap bleeding and avoid stress. Never prune in spring or summer when the tree is in active growth. For young trees, focus on establishing a clear central leader and removing competing leaders or crossing branches. Cut back any low laterals that might obstruct pathways or sightlines, aiming for a clear trunk of at least 2 to 3 metres. Use sharp bypass secateurs for small branches and a pruning saw for anything thicker than your thumb. Always cut just outside the branch collar—the slight swelling where the branch meets the trunk—to promote natural healing. Mature London planes rarely need pruning beyond removing dead, damaged, or diseased wood. Check annually for broken branches, especially after storms, and remove these promptly to prevent decay entering the main trunk. If branches overhang buildings, roads, or utilities, hire a qualified tree surgeon; large limbs are heavy and dangerous to remove without proper equipment and training. Avoid heavy crown reduction or topping, which disfigures the tree and encourages weak, vigorous regrowth prone to disease. London plane naturally sheds its bark in irregular patches, revealing cream and grey mottled wood beneath—this is normal and not a sign of ill health. If you notice cankers, oozing lesions, or dieback, consult an arborist, as plane anthracnose and other fungal diseases occasionally affect stressed trees.
