Honey locusts are drought-tolerant once established. Water deeply and infrequently during the first year to encourage a strong root system.

After establishment, supplemental watering is rarely needed, except during prolonged dry periods. Ensure good drainage to prevent waterlogged soil, which can lead to root rot.

Prune honey locusts to shape the tree, remove dead or damaged branches, and improve structure. The best time for major pruning is during the dormant season (late winter or early spring).

Remove crossing branches, watersprouts, and suckers to maintain a strong, open canopy. Consider thorn removal on cultivars if desired.

Propagation is typically done by seed, which requires scarification or stratification to break dormancy. Cuttings can also be used, but are more challenging.

Grafting is common for desirable cultivars, allowing for consistent traits. Sow seeds in spring after appropriate pre-treatment.

Repotting is generally not applicable to Gleditsia triacanthos as it is a large, long-lived tree.

Young specimens grown in containers should be repotted when root-bound, typically every 2-3 years, using a well-draining soil mix. The best time for repotting is in early spring before new growth begins.
