Dahlia Care & Planting Tips

  • GROUND PLANTING

    Dahlias perform best in fertile, well-drained soil in full sun. Prepare a hole deep enough & wide enough (10-15cm) to accommodate your tubers, like an outstretched hand. In the base of the planting hole add composted manure or a rich compost and some grit if your soil is heavy.
