Growing at a glance…
Water freely during the growing season and make sure to dead-head regularly to prolong flowering.Unpack immediately upon arrival and give them a little water if needed. If potting up into containers, use a balanced compost (that is not too peaty) as it is inclined to produce a hard crust if allowed to dry. We recommend a John Innes Compost No 2.
