Required Growing Conditions
Yellowleaf hawthorn grows widely in the southeastern U.S., from Virginia to Florida. For current distribution, please consult the Plant profile page for this species on the PLANTS Web site.
Adaptation Although yellowleaf hawthorn will succeed in partial shade and different soil types, it grows best in full sunlight, in dry soil of rocky areas, well-drained sandy soils. It will tolerate wet soils before becoming drought tolerant once established. It is wind tolerant making it a good tree species in shelterbelt planting. Yellowleaf hawthorn is tolerant of atmospheric pollution and performs well in urban settings.
Cultivation and Care
Propagation from Seed or Grafting: Yellowleaf hawthorn can be propagated by either seeds or grafting. Successful propagation using seeds requires acid scarification followed by warm stratification and prechilling. Seeds are planted early in the fall, in drill rows eight to twelve inches apart and covered with 1/4 inch of soil. Seedlings must not be kept in the nursery longer than a year.
Containerized trees should be planted when they are no more than eight feet tall, in the fall or spring. Balled and burlapped trees should be planted in early spring.
Grafting on seedling stock of Crataegus oxyacantha or Crataegus monogyna is best carried out in the winter to early spring.
General Upkeep and Control
Pruning should be done in the winter or early spring in order to maintain a clear shoot leader on young trees and/or remove the weakest branches to allow more light to pass through. Suckers or stems arising from the roots should be removed when they become noticeable.
Pest and Potential Problems Although pests and diseases seldom affect it it is susceptible to fireblight, cedar-hawthorn rust, cedar-quince rust, leaf blight and fruit rot, and leaf spot.
