Planting & Care – Lisbon Lemon

Site Selection

  • Select a sunny location to support strong growth and fruiting.
  • Lisbon benefits from warm exposures and good air circulation.
  • Avoid low spots where cold air settles.

Soil Preparation (In-Ground vs Container)

  • In-ground: Ensure excellent drainage; raised planting helps in heavier soils.
  • In-ground: Slightly acidic soil (pH 5.5–6.5) supports nutrient availability.
  • Container: Use a fast-draining citrus mix in a container with drainage holes.
  • Container: Larger pots help support Lisbon’s vigorous growth.

Planting Instructions

  1. Dig a hole about twice the width of the root ball, or choose a container slightly larger than the root mass.
  2. Plant so the root flare sits at or slightly above finished soil or potting mix.
  3. Backfill gently and water thoroughly.
  4. Mulch in-ground trees lightly, keeping mulch away from the trunk.

Watering (In-Ground vs Container)

  • In-ground, establishment: Maintain evenly moist soil during the first growing season.
  • In-ground, established: Deep, periodic watering encourages strong root systems.
  • Simple check: Water when soil is dry 3–6″ below the surface.
  • Container: Water thoroughly, then allow the top couple inches to dry before watering again.

Fertilizing

  • Lisbon lemons are heavy feeders and respond well to regular nutrition.
  • Base feeding: Apply slow-release citrus fertilizer in early spring and again in early summer.
  • Support feeding: Supplemental liquid fertilizer during active growth promotes flowering and fruit set.
  • Ease back on feeding later in the season to help the tree harden before winter.

Cold Care

  • Lisbon tolerates cool conditions better than many lemons once established.
  • Protect young trees during hard freezes.
  • Container trees can be moved to sheltered locations during cold snaps.

Pruning & Harvest

  • Prune lightly to manage size and encourage airflow.
  • Harvest fruit when fully colored and aromatic.

General Tips

  • Strong sun, drainage, and consistent feeding unlock Lisbon’s full potential.
  • A great choice for growers who want a tougher, more vigorous lemon.
