If you haven't planted out now is the time to do so, just check there are no late frosts forecast but I'd say that for this year they are now past. Begin the outdoor hygiene programme by keeping the ground well hoed to prevent weeds and to keep the ground aerated. Stake all dahlias if not done before planting.
7-10 days after planting the first top dressing may be applied. A good general purpose fertiliser, fish, blood and bone is used at Withypitts Dahlias. Tomorite is also good, not just for tomatoes!
