Cultivation Details
Salix gracilistyla is a moderately cold-hardy plant, able to tolerate temperatures down to around -20°c when fully dormant. Salix species generally require an open position and abhor dryness at the roots. Whilst many can be found in wet or boggy soils, and prefer a damp, heavy soil, most will grow well in a range of moist but well-drained soils so long as they are fairly deep. Very few are at home in chalky soils[1, 2, 3]. A very ornamental plant[4]. The flowers are dioecious, male and female flowers being produced on separate plants. If seed is required then at least one plant of each sex need to be growing in reasonable proximity[1]. Hybridization in the genus is common, especially when species are brought together in cultivation[2]. Salix species are unusual in as much as, although they produce their flowers in catkins, these are insect rather than wind pollinated. Indeed, the flowers of many species are excellent sources of nectar for bees and other insects, especially valuable are those species that flower early in the growing season[1]. The roots of Salix species are often vigorous and extensive and can range some distance from the plant. Several species are known to cause problems by growing into drains and drainage systems as their roots seek out moisture[1]. Species in this genus are often notably susceptible to honey fungus[2].
Propagation
Willow seed is very small and light, and has a very short viability, perhaps as little as a few days in some species. It must be surface sown as soon as it is ripe. In nature the seed only germinates in disturbed soils in an open situation. In nursery conditions, sow the seed in a tray in a moderately sunny position and keep the soil moist. Germination is usually quite rapid - prick out the seedlings into individual pots when they are large enough to handle and grow on until large enough to plant out. Plants generally establish better if planted out whilst quite small. Cuttings of mature wood of the current year's growth or older can root at almost any time of the year, though late autumn is considered best as this produces a better balance of root and stem growth the following spring[3]. Plant them in a sheltered outdoor nursery bed or straight into their permanent position and give them a good weed-suppressing mulch. Most species are very easy. Plant into their permanent positions in the following autumn. Cuttings of half-ripe wood, early to mid summer in a frame. Very easy.
