When does summer start? 1st June? The summer solstice? Or when the first dahlia is in flower?
For me, summer starts when I see the plants I associate with summer starting to flower, and dahlias are good from now until the first frosts in mid/late autumn.
Surprisingly easy to overwinter, you only need to lift dahlias tubers in winter if you have a heavy soil, or one that remains waterlogged.
In many Malvern soils, protect the crown of the plant to successfully get the tubers to last yet another year.
For transparency, the image we have used this week is made using AI to amalgamate three separate photos of dahlias we have taken at the nursery on the day this post was published.
