A fertile, sunny to partially sunny position with wind shelter is the best spot for Twombly’s Red. It copes with full sun better than other more delicate acers, but too much direct sun scorches its leaves - the best foliage colour will emerge with some shade. Regular pruning isn’t needed and may ruin its shape but you can cut away crossed or damaged branches in the dormant season. Water well until established and ensure that container-grown acers are watered and fed throughout the hot or dry months. Container-grown acers should also be propped up on feet during the winter to allow the roots to freely drain and avoid frost damage from extreme cold.
