How to Plant Citrus in San Diego for Sweet Fruit Fast

Sweet fruit starts with drainage, graft height, and deep watering — not with burying the trunk in lawn spray.

Now

Dig wide and plant slightly high, graft union above soil.

Why

Citrus wants full sun, wind protection, and well-drained soil.

Next

Water the root ball until roots enter native soil; mulch 6–12 in off the trunk.

Kit

  • Healthy citrus on appropriate rootstock
  • Shovel; hole about 2× root-ball width
  • Mulch (keep 6–12 in off trunk)
  • Drip or basin watering setup
  • Optional diluted white latex for trunk sunburn protection

Do this

  1. Pick sun and air flow

    Full sun with wind protection. Avoid planting in lawn.

  2. Dig wide, plant slightly high

    Hole about twice the root-ball width. Set the root ball about 1 inch above surrounding grade so it settles level — not in a bathtub.

  3. Keep the graft above soil

    Do not bury the graft/bud union. Remove suckers that sprout below it.

  4. Water deep, then mulch

    Water immediately. Keep the root ball moist (not soggy) until roots enter native soil — new trees may need several soaks a week in heat.

  5. Skip lawn irrigation on the trunk

    Use a basin or drip rings. Mature citrus may need several inches of water per month in summer heat, split by soil type.
