Step by step: plant golden Chain Tree
Golden chain tree thrives in full sun or partial shade, though flowering is most prolific in a sunny position sheltered from strong winds. It tolerates a wide range of soils—loam, chalky, or sandy—provided drainage is reasonable. Avoid waterlogged sites, as the roots dislike sitting in wet conditions over winter. Plant bare-root specimens in March, April, or from September to October when the soil is workable and not frozen. Container-grown trees can go in during the same months, though autumn planting gives roots time to establish before the growing season. Dig a hole twice the width of the root ball and roughly the same depth, breaking up compacted soil at the base to encourage drainage. If your soil is heavy clay, fork in coarse grit or horticultural sand to improve structure. Position the tree so the top of the root ball sits level with the surrounding soil—planting too deep can lead to stem rot. Backfill with the excavated soil, firming gently with your heel to eliminate air pockets. Space trees at least four metres apart to allow for their mature spread of three to five metres. Water thoroughly after planting, applying at least two full watering cans to settle the soil around the roots. Apply a 7–10 cm layer of well-rotted compost or bark mulch around the base, keeping it clear of the trunk itself to prevent rot. Stake young trees with a single angled stake and a tree tie if the site is exposed, checking and loosening the tie every few months as the trunk thickens.
