They will probably be fine as they're both hardy and prolific plants! For future - if you can get hold of some young willow (whilst it's still green and stripped of leaves) - then cut the branches and pop in a jar, cover with boiling water and leave for 24 hours. You can then use that to soak cuttings prior to 'plonking' or you can dilute it 3:1 with water and water cuttings with it. Willow creates natural rooting hormones - it's always good to make a demijohn early in the year and keep a stock of it. :)
