Water regularly, especially during establishment and dry periods. Allow the soil to dry slightly between waterings. Reduce watering in winter.

Ptelea crenulata prefers consistent moisture but can tolerate short dry spells once established. Avoid waterlogged conditions, which can lead to root rot.

Prune to shape and remove dead, damaged, or crossing branches. Light pruning can be done in late winter or early spring before new growth emerges.

Remove any suckers from the base of the plant to maintain its desired form. Heavy pruning is generally not required.

Propagation is typically done by seed, which requires stratification. Sow seeds in spring after a period of cold stratification. Cuttings can also be taken from semi-hardwood in summer, though success rates may vary.

Patience is key for successful propagation.

Repot young plants as needed, usually every 2-3 years, in spring. Choose a pot only slightly larger than the current one. Use a well-draining potting mix.

Mature plants generally do not require frequent repotting and prefer to be left undisturbed.
