Planting

How to Grow

  1. Select a site in full sun receiving at least six to eight hours of direct daily sunlight.
  2. Improve heavy soils by mounding or incorporating organic matter to guarantee high drainage.
  3. Plant the graft union well above the soil level to prevent collar rot.
  4. Water deeply and regularly during the establishment phase and throughout fruit development.

Pro Tip

Avoid planting into heavy clay soils without mounding to improve drainage, as waterlogged roots quickly succumb to Phytophthora root rot.

Keep It Thriving

Care Guide

Do

  • Feed with a dedicated citrus fertiliser every six to eight weeks during the warm growing season.
  • Prune lightly in late winter to open up the canopy and remove dead wood.
  • Apply mulch around the root zone, keeping it clear of the main trunk.

Don't

  • Do not allow the soil to become waterlogged or boggy.
  • Do not prune heavily or unseasonably, as this triggers soft flushes that attract citrus gall wasp.
  • Do not use rootstocks such as Poncirus trifoliata, Troyer, or Carrizo citrange due to incompatibility.
