Flowers

Timed for a typical UK garden (last frost mid-April). The app uses your own town's frost dates.

Late April – late May · 2 weeks after the last spring frost
Plant Outdoors
Plant 10–15 cm deep, 25 cm apart, in rich soil in full sun once frosts are over.
14–28 days after “Start Tubers in Pots” · Mid May – late May
Look for Shoots
Shoots should be up. Protect them from slugs — they love young dahlia and gladiolus shoots.
30–70 days after “Plant Out” · Mid June – late July
First Flowers — Deadhead Regularly
Cut faded flowers (and flowers for vases) to keep new buds coming. Take a photo for your journal!

March
Start Them Off Again
Check stored tubers/corms, discard any soft ones and pot them up (or plant out once frosts are over).
October
Lift and Store
After the first frost blackens the leaves, cut stems to 10 cm, lift, dry off upside down, and store in dry compost somewhere frost-free.
