Hi @kpr
Great news on the new flamingo trees, what a brilliant choice for high visual impact! They're one of those small trees that stops people in their tracks when they see that stunning pink, white and green variegated foliage for the first time. To answer your question directly: yes, you can tidy up that leggy growth, but timing is everything here and getting it right will make a significant difference to how well your trees respond.
Wait Until Winter for the Main Prune
The golden rule for flamingo trees (Salix integra 'Hakuro-nishiki') is to prune in the dead of winter when they're completely dormant, ideally between December and February. This is the window where the tree has no leaves, minimal sap flow, and pruning wounds can heal cleanly when growth resumes in spring.
Hold off on tackling that leggy growth right now, even though it's tempting. Autumn pruning causes pruning shock because despite the leaves beginning to fall, the tree is still physiologically active, which means wounds don't seal properly and the tree battles through winter with fresh cuts it can't yet heal. The leggy growth looks untidy, I know, but leaving it until December is the right call and your patience will be rewarded with a much healthier response come spring.
What You Can Do Right Now
Dead, diseased, or damaged wood is the one exception. If you can spot branches that are dark brown or charcoal coloured with no visible buds or flexibility, those can come off now regardless of season. A quick way to check whether a branch is alive is to scratch the bark gently with your fingernail. Green or moist tissue underneath means it's alive, dry brown tissue all the way through means it can go.
Also keep a close eye on the trunk of both trees, particularly around that knobbly swollen area which is the graft union. Plain green leaves shooting from the trunk below this point are suckers from the rootstock rather than your flamingo tree, and they'll steal vigour from the ornamental top if left unchecked. Off they come as soon as you spot them.
How to Tackle Leggy Growth in Winter
When December arrives and you're ready to prune, cut back the long extended stems to just above an outward-facing bud, taking off roughly a third to half the length on the worst offenders. This encourages fresh, well-structured growth from lower down the stem in spring rather than the tree continuing to extend in the same spindly direction. Sharp, clean secateurs matter here as blunt blades crush and tear rather than cutting cleanly, which slows healing and can let infection into fresh wounds.
Don't be nervous about pruning fairly decisively once you're in that winter window. Flamingo trees respond brilliantly to a confident prune and come back with bushy, vigorous growth that looks far better than if you'd left those leggy stems to carry on doing their own thing.
