Cultivation Details
Celtis planchoniana can be fairly cold-hardy when growing in hot summer areas, able to tolerate temperatures falling to at least -15°c[1]. However, Celtis species generally prefer hotter summers and more sunlight than are normally experienced in maritime regions of the temperate zone. In areas with cooler summers the plants often do not fully ripen their wood and are then very subject to die-back in the winter[2, 3, 1]. Succeeds in any reasonably good soil, preferring a good fertile well-drained loamy soil[2, 3, 1]. Succeeds on dry gravels and on sandy soils[1]. Established plants are very drought resistant[4, 1].
Propagation
Seed - best sown as soon as it is ripe in a cold frame[1]. Stored seed is best given 2 - 3 months cold stratification and then sown late winter/early spring in a greenhouse[5, 1]. Germination rates are usually good, though the stored seed might take 12 months or more to germinate. The seed can be stored for up to 5 years[6]. As soon as they are large enough to handle, prick the seedlings out into individual pots. The leaves of seedlings often have a lot of white patches without chlorophyll, this is normal and older plants produce normal green leaves. Grow the seedlings on in a cold frame for their first winter, and plant them out in the following late spring or early summer[PFAF]. Give them some protection from the cold for their first winter outdoors.
