Growing at a glance…
Unpack your plants immediately upon arrival and give them a little water if they feel a bit dry. Pot on for 2-3 weeks before planting them out into their final positions outdoors. Alternatively, you can plant these plugs directly outdoors if the weather permits (all risk of frost is gone). Water these plants freely during the growing season and make sure to dead-head spent flowers regularly to prolong their display.
