The arboretum team have been out planting some new trees along Kew's historic vistas. This is to ensure they are maintained for generations to come.
Every year in the Arboretum we plant around sixty new young trees. These are to replace old trees lost and also to add diversity to Kew's tree collection, which currently numbers around 14,000 individual trees. Most of these are grown in our own Arboretum nursery, as seed raised plants, from natural source, meaning they are grown from seed legally collected in the wild, and from seed donated from other botanic gardens and arboreta around the world. We also grow many from vegetative material i.e. grafts and cuttings.
Usually the trees are small and easily manageable, requiring only normal hand tools to lift, move and to plant them.

We also plant much larger trees, bought in from UK nurseries. These trees are usually around 10-15 metres tall and weigh around three tonnes.
Over the last ten years we have been replanting some of the gaps left from losses of mature trees that grew along our historic vistas which were designed by William Nesfield and originally planted in the mid-1800s.
The vistas make up a triangle consisting of Syon vista, lined with evergreen holm oaks, Cedar vista, the longest of the three vistas, lined with cedars, and Pagoda vista, lined with deciduous pairs of trees, with a secondary vista of cedars.
The old photo below shows the original planting of the Pagoda vista, planted with its matched pairs of broadleaved trees flanked with a secondary planting of cedars (Cedrus deodara), and showing the old tea pavilion, top right, which was burnt down by the suffragettes in 1913! On that spot now stands the Pavilion restaurant.

This year we are strengthening the 850 metre-long Pagoda vista. The large tree being planted here is an American tulip tree (Liriodendron tulipifera.)

We decide the previous year which areas need replanting and then source the trees from large tree nurseries. Deepdale Trees is our main supplier, they will find what we need and then grow them on for us until we are ready to plant.
Unlike our normal tree planting, which is all done by hand, big trees call for big machines, so from digging the hole to positioning the tree it is all done with machines. These easily cope, making the job both quicker and less strenuous!
The large tree pits, though, are finished off by hand, ensuring the correct depth and final position of the tree.

Trees arrive on large lorries, usually two or three to a lorry depending on size.

They are then unloaded and delivered to their new home, to planting holes measured to exactly fit in, both with the tree opposite and those along the length of the vista.

Once we are happy with the trees' positions, they can be back filled, have a new mulched circle, and take their place in the future history of Kew's vistas. Hopefully for generations to come.
