Organic Dahlia planting instructions – 

DAHLIAS are easy to grow and will add some wonderful colours to your garden. They are tolerant of a wide range of soil types and situations but perform best in fertile, well-drained soil in full sun. Prepare the soil using compost, well rotted manure or a general NPK fertilizer.

• Tubers can either be started off in large pots of quality organic potting compost in April and planted out after all risk of frost is over in May/June; or planted directly were they are to flower in May/June.
• Tubers should be planted 10-15cm deep.
• Stake as required and pinch out shoots to promote bushiness (see pruning and training below)
• Keep well-watered and once flowers appear feed with a high potash liquid feed every two weeks from July to early September.
• Watch out for slugs!  Dahlias are quite a favourite.
• Once the plants have died back in autumn/winter you can either lift and store the tubers or leave in situ  and cover with a thick layer of compost or leaf mould to protect from frost.
