After the season of growing begins, which typically occurs from spring to fall, regular watering for the plant is required to maintain soil moisture. A recommendation would be to thoroughly water the Formosan ash plant once per week. The depth that the water penetrates into the root zone is important.

In contrast, for the resting dormant season in winter, watering frequency may be less for the Formosan ash plant. Allowing the soil to partially dry out between waterings avoids overwatering and root rot. Watering once every 2 to 3 weeks should be adequate during winter dormancy. Soil moisture level monitoring is important to determine appropriate watering frequency. Use of a moisture meter or checking the soil moisture with a finger to the second knuckle depth will reveal if the soil feels dry and requires watering. Overall, providing sufficient water on a routine schedule tailored to the plant's seasonal needs and soil condition promotes a thriving Formosan ash plant.

This affects ability to transport water and nutrients. Another pest, the ash/lilac borer (Podosesia syringae), attacks weakened or stressed trees, causing damage to trunk and branches. Infested trees can wilt or die. A fungal disease called ash dieback (Hymenoscyphus fraxineus) causes leaf loss and crown dieback. It spreads through spores and can eventually kill trees. Pruning infected branches and promoting vigor through care can reduce impact. Insecticides can protect from borers, but fungicides not effective for ash dieback.
