Olea europaea · Tree/Shrub

A slow, long-lived Mediterranean tree with silvery leaves and gnarled trunks. It handles drought, heat and poor soil, and grows well in large containers on a sunny patio. Fruiting needs a cool winter.

When?

Plant in spring once frost is past, so roots establish over a warm season. Container trees can be repotted in spring every 2–3 years.

Step by step

  1. Choose the sunniest, most sheltered spot you have.
  2. Plant at nursery depth in fast-draining soil; avoid low wet areas.
  3. Water weekly during the first summer, then only in long dry spells.
  4. Feed lightly in spring with a balanced fertilizer.
  5. Prune in late winter or early spring to open the center to light.
  6. In pots, move to a bright, cool, frost-free place in harsh winters.
  7. Pick fruit green or black in fall; fresh olives must be cured before eating.

Common problems

Leaf drop indoorsToo little light; move to the brightest window or outside in summer.
Yellow leaves, wet soilOverwatering or poor drainage; water less and improve drainage.
No fruitNot enough winter chill or a young tree; be patient and keep it outdoors in winter if possible.

Pets

Olive is listed as non-toxic to cats and dogs; large amounts of fruit may still upset the stomach. If in doubt, ask your vet.
