Water regularly, especially when young, to keep the soil consistently moist. Once established, Ptelea trifoliata is relatively drought-tolerant but performs best with occasional deep watering during dry periods.

Avoid waterlogged conditions, which can lead to root rot. Allow the top few centimeters of soil to dry out between waterings.

Pruning is primarily for shaping and maintaining size. Prune in late winter or early spring before new growth emerges. Remove any dead, damaged, or crossing branches.

Light pruning can be done after flowering to encourage a denser habit. Avoid heavy pruning, as it can reduce flowering and fruiting.

Propagate by seed sown in autumn or by semi-hardwood cuttings taken in summer. Seeds require stratification; sow them in pots outdoors or in a cold frame.

Cuttings should be treated with rooting hormone and placed in a well-draining medium in a humid environment. Patience is key for successful propagation.

Young plants benefit from repotting every 2-3 years in spring to refresh the soil and provide more space. Established trees rarely need repotting and are best left in their permanent location.

If repotting is necessary, use a well-draining potting mix and move to a slightly larger container.
