With dazzling blooms from mid-summer to late autumn, these tuber-rooted perennials are great for adding late seasonal interest. They are large enough specimens to use as a stand-alone plant in a pot but equally perfect for plugging gaps borders as long as they are in full sun and free-draining soil.

Bulb Starter

Endorsed by the RHS and designed around the recognised rootgrow mycorrhizal fungi family of plant related feeding additives. Bulb Starter also includes vermiculite to ensure good drainage in the root zone and seaweed meal as a source of natural auxin's to stimulate root development.
The product also contains humates as a source of organic acids for both the treated bulb and soil microorganisms.
Application: Use 5-10g for small bulbs or corms, 10-20g for large bulbs or tubers. (One palm full is approximately 10g)

Place Bulb Starter into the base of the planting hole, backfill and water.

Planting Advice: Follow the planting guidelines supplied with your bulbs, corms or tubers. Generally bulbs are planted two or three times their own depth into the soil with the bulb head facing upwards, ensuring there are no air gaps near the bulb.

Cultural Notes

  • Soil - Well drained, moderately fertile.
  • Position - Sun or part shade
  • Cutting - Yes
  • Flowering - June to November
  • Additional Information - Dahlias benefit from a high nitrogen liquid fertilizer weekly in early summer and a high potash fertilizer weekly in mid summer to early autumn. Dead head as flowers fade to prolong flowering. When foliage is blackened by the frosts the tubers can be lifted, kept dry and frost free. Dahlias can be left in the ground if free draining soil. They need to be mulched and cover with plastic to keep dry. Plant these out after the frosts. Tuberous tender perennial.
