Cultivation
In favourable conditions, notably a moist, well-drained soil, the tree can grow at a rate of almost one metre per annum. Trials by the Northern Arizona University found that it is not very tolerant of a hot, arid environment although its leaves sustain comparatively little scorch damage. In trials in southern England conducted by Butterfly Conservation, the tree was found to be intolerant of ponding overwinter.
'Sapporo Autumn Gold' was first introduced to the UK by technology company Pitney Bowes as part of its 'Elms Across Europe' campaign. The company supplied the cultivar to schools, parks and gardens throughout the UK and Europe. The tree remains popular in continental Europe but does not assimilate well in the countryside. In trials in France by Cemagref at Nogent-sur-Vernisson, Loiret, it was found to grow too vigorously in hedgerow conditions, eclipsing neighbouring shrubs and consequently creating gaps. The hybrid was included in trials in Canberra, Australia started in 1988, but has not performed well there.
Planted in Northamptonshire, England, 'Sapporo Autumn Gold' was found to make an acceptable host for the endangered White-letter Hairstreak butterfly Satyrium w-album, whose larvae feed exclusively on elm

Famous quotes containing the word cultivation:
“... in the education of women, the cultivation of the understanding is always subordinate to the acquirement of some corporeal accomplishment ...”
—Mary Wollstonecraft (1759–1797)
“The cultivation of one set of faculties tends to the disuse of others. The loss of one faculty sharpens others; the blind are sensitive in touch. Has not the extreme cultivation of the commercial faculty permitted others as essential to national life, to be blighted by disease?”
—J. Ellen Foster (1840–1910)
“We Russians have assigned ourselves no other task in life but the cultivation of our own personalities, and when we’re barely past childhood, we set to work to cultivate them, those unfortunate personalities.”
—Ivan Sergeevich Turgenev (1818–1883)
