Block form trees work most effectively when planted in pairs or avenues. They accentuate height and structure and can be under planted with low formal hedges or topiary plants. Often used to frame vistas, create natural divides or give a sense of depth, box head trees are popular with designers and landscape architects alike.
Hornbeam (Carpinus betulus) is the most popular species choice by far for block form trees. Hornbeam is easy to grow and it enjoys being managed and thrives in most soil types. Other popular species include:
Acer campestre (Field Maple) ‘Elsriijk’, Acer campestre ‘Red Shine’
Fagus sylvatica (Beech)
Fagus sylvatica ‘Atropurpurea’ (Copper Beech)
Quercus ilex (Pin Oak)
Platanus acerifolia (London Plane)
Quercus palustris (Pin Oak)
Tilia europaea ‘Pallida’ (Lime), Tillia cordata ‘Greenspire’
Parrotia persica (Ironwood)
Pyrus salicifolia ‘Pendula’ (Weeping Pear)
Platanus hispanica ‘Malburg’
The block form trees we supply have reasonably standard dimensions on top. The blocks are available as cubes of 100cm width/height/depth, in some species we can offer them with larger cubes. Trees with stem girths of 30cm and above, will typically have fuller more mature cubes or blocks on top. The crowns in younger trees tend to incorporate heavy duty welded metal frames that ensure uniform clipping and safety while being transported. More mature, established specimens tend to be supplied without the wire frame.
Why not contact us to find out more about our outstanding range of bespoke trees, in unusual sizes? We offer an assortment of larger block sizes if more impact is required. We can supply trees with lower stem heights which is particularly useful if they are being used in raised beds or planters, where a tall stem would not work – the reduction in stem height compensates for the higher planting level.
Like our pleached trees, planting technique is critical to get the best results from block form trees. Being a dominant three-dimensional structure, it is essential to set the lines and levels correctly when planting, so that symmetry is achieved on completion. We offer a nationwide planting service and we are specialists in the supply and planting of form trees.
