Water newly planted Silvertop-Ash regularly until established. Once mature, it is highly drought-tolerant and requires minimal supplemental watering, especially in its native range.

Overwatering can lead to root rot, so ensure well-draining soil and allow the soil to dry out between waterings.

Pruning is typically minimal for Silvertop-Ash, primarily for shape, removing dead, damaged, or crossing branches. Light pruning can be done after flowering or in late winter to maintain structure.

Avoid heavy pruning, as it can stress the tree and encourage epicormic growth.

Propagation is best achieved from fresh seed collected from mature trees. Seeds require a period of cold stratification to improve germination rates.

Sow seeds in a well-draining, sterile potting mix and keep moist and warm. Grafting onto suitable rootstock is also an option for specific cultivars.

Repotting is generally not necessary for established trees, as they are long-lived and prefer to remain undisturbed. Young seedlings or container-grown plants may require repotting into a larger container as they outgrow their current one, typically every 1-2 years, using a well-draining potting medium.
