What are common floral arrangement mistakes?

One of the biggest mistakes is picking flowers that aren't in season in the UK. You'll pay more and get blooms that don't last. Another is ignoring scent: some flowers smell wonderful, but others have no scent at all, so think about what you want guests to experience. Overloading with too many colours or too many different flower types can look messy rather than elegant. Stick to a clear palette and a few hero blooms. Also, consider the venue: a huge barn needs bigger, more abundant arrangements, while a small register office might be overwhelmed by a giant centrepiece. Lighting matters too, as dark venues need brighter flowers. Don't forget practicalities: flowers need to be conditioned, hydrated, and kept cool before the ceremony. If you're doing DIY, start early and have a backup plan. Finally, don't forget the bridal party's bouquets and buttonholes, and make sure they match the overall style. A common oversight is not checking the weight of the bouquet, so you're not struggling to hold it during the ceremony.
