Growth—

The natural range of Ulmas alata has a climate that varies from warm in the South to moderately cold in the North. The region is principally within the humid climatic province of the southeastern United States, with a mean annual precipitation ranging from 1,020 - 1,520mm, with half or more of this occurring during the growing season. Throughout the greater portion of the tree's range, the growing season averages from 180 to 300 days, and average annual temperatures are from 13 - 21°c[1]. Prefers a position in full sun, but tolerates light shade[2, 3]. Grows best in a moist, fertile, well-drained loamy soil, but can adapt to most soils and drier sites[3]. Plants are tolerant of urban pollution[3]. A fast-growing tree in its native range[4]. The plant survives grazing as bushes and sprouts prolifically from the base after a fire[5]. This species is susceptible to 'Dutch elm disease'[6], a disease that has destroyed the greater part of all the native elm trees growing in countries such as Britain and USA. The disease is spread by means of beetles. Mature trees killed back by the disease will often regrow from suckers, but these too will succumb when they get larger. There is no effective cure (1992) for the problem, but most E. Asian, though not Himalayan, species are resistant (though not immune) to the disease so the potential exists to use these resistant species to develop new resistant hybrids with the native species[7]. The various species of this genus hybridize freely with each other and pollen is easily saved, so even those species with different flowering times can be hybridized[7].

Propagation

Seed - if sown in a cold frame as soon as it is ripe, it usually germinates within a few days[7]. Stored seed does not germinate so well and should be sown in early spring[7]. The seed can also be harvested 'green' (when it has fully developed but before it dries on the tree) and sown immediately in a cold frame. It should germinate very quickly and will produce a larger plant by the end of the growing season[8]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Plants should not be allowed to grow for more than two years in a nursery bed since they form a tap root and will then move badly. Layering of suckers or coppiced shoots[7].
