Cultivation Details

HabitEvergreen Tree
GrowthSlow

Sophora tetraptera is not very cold hardy, tolerating short periods with temperatures down to about -10°c when it is fully dormant[3], Mature plants, with a woody framework, are considerably hardier than young plants, which can often be killed even in fairly mild winters[4]. Succeeds in a well-drained moderately fertile soil in full sun[3]. Requires a warm sheltered position[5]. Plants are of slow to moderate growth[5]. In good summers plants can set seed abundantly in cultivation[6]. Plants should be container-grown and planted out whilst young, older plants do not transplant well[6]. Plants in this genus are notably resistant to honey fungus[3]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[7].

Propagation

Seed - best sown as soon as it is ripe in a greenhouse[3]. Pre-soak stored seed for 12 hours in hot (not boiling) water and sow in late winter in a greenhouse[8]. Prick out the seedlings as soon as they are large enough to handle into individual pots in the greenhouse, and grow them on for 2 years under protected conditions. Plant them out into their permanent positions in early summer of their third year. Cuttings of young shoots with a heel, mid summer in a frame[4]. Air-layering[3].
