This year it’s the "tougher challenge of holding back and cooling down" 20,000 plants for Chelsea, he says.
Kelways is sourcing and growing for six main show gardens and assisting with five others including three trade stands.
Root says most challenging has been the Massachusetts Garden because the plant list is so specific and because Cape Cod spring comes very late.
The Somerset grower is supplying Alan Titchmarsh's Britain in Bloom garden, where orders for plants came six months after other Chelsea gardens. Echium pininana, Loquat Eriobotrya japonica and Adiantum venustum are the most important plants.
For the Kelways stand in the pavilion the grower shows irises and peonies, with P.Moonrise a highlight.
Root will launch a new edition of Kelways Gardens of Delight, which was first published in 1909, at the show.
