I will recieve a few cuttings of a willow Salix Triandra Semperflorens. This willow flowers all the way from February until the frost hits. Such plant is of great benefit to the bees and I am planting alot of bee friendly plants, shrubs and trees this year.
Im asking since we still have snow in Sweden and not sure if I can simply stick the cutting into the cold ground or should I stick them into a pot and then place outdoors?
All help highly appreciated! I really want this willow to take off so I can help spread it.
Willows are very good at rooting, though I don't know that particular species. Here in Ladakh we propagate about 6 species of willow, all by cuttings, and putting them in cold ground is absolutely fine. We cut and plant in the beginning of winter or end of winter, but not in mid-winter because our soil is frozen hard. Of course keep the lower end of the cuttings in water or at least moist at all times from cutting until planting; If in doubt, cut off some of the lower end. Cuttings of any size work. Here we always use ones at least 2 or 3 cm diameter, with at least 45 cm (1.5 feet) below ground and at least 120 cm (4 feet) above ground to help them get a head start above browsing animals -- but pencil sized cuttings root well too.
One thing is be sure to plant them while they are dormant. We always have some cuttings still standing in water as the spring warms up, and once their leaf buds swell, if we still plant them most of them die.
