Elaeagnus formosana

Seed - best sown as soon as it is ripe in a cold frame^[3]. It should germinate in late winter or early spring, though it may take 18 months[K]. Stored seed can be very slow to germinate, often taking more than 18 months. A warm stratification for 4 weeks followed by 12 weeks cold stratification can help^[4]. The seed usually (eventually) germinates quite well^[3]. Prick out the seedlings into individual pot as soon as they are large enough to handle and plant out when they are at least 15cm tall.

Cuttings of half-ripe wood, 7 - 10cm with a heel, July/August in a frame. Cuttings of mature wood of the current year's growth, 10 - 12cm with a heel, October/November in a frame^[5]. The cuttings are rather slow and difficult to root, leave them for 12 months^[6].

Layering in September/October. Takes 12 months^[3].

We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it could succeed outdoors at least in the milder parts of this country. The following notes are based on the general needs of the genus.

Succeeds in most soils that are well-drained^[5]. Prefers a light sandy soil that is only moderately fertile, succeeding in poor and dry soils^[7][5]. Very drought and wind resistant^[7][5]. 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^[5]. An excellent companion plant, when grown in orchards it can increase yields from the fruit trees by up to 10%.

This species is notably resistant to honey fungus^[8][5].
