Description
The olive tree (Olea europaea) is a symbol of the Mediterranean, a long‑lived evergreen tree with silvery, shimmering foliage and a knobby trunk. Its fruits are bitter and inedible raw; they must be pickled or pressed into oil before consumption. In most DACH regions it is not winter‑hardy and is typically grown in a pot, tolerating only sunny, frost‑free summers and a protected winter location.
Care instructions
Place the olive tree outdoors in full sun from May (week 19) to October. Use a well‑draining, relatively lean potting mix. Water deeply but allow the soil to dry out between waterings; waterlogging is its greatest enemy. Overwinter in a bright, cool spot at 2 to 10 °C (e.g., a stairwell or cold winter garden) and water sparingly. Prune in spring (April, week 15) to open up the canopy and let light reach the interior.
