About Olive Tree

Olea europaea · also called common olive, European olive · edible

The olive is a long-lived evergreen Mediterranean tree with silvery-grey leaves, grown for fruit, oil, and as an architectural specimen. It loves full sun and sharp drainage, tolerates drought and poor soil, and survives short frosts to around -10C. In cool climates it makes an excellent container plant needing winter shelter.

Mature size: 4-8 m tall in the ground over decades; easily kept to 1.5-2.5 m as a clipped container or patio tree.

Watch for — Root rot from overwatering: Soggy soil is the commonest cause of decline. Use very free-draining compost, let pots dry between waterings, and never leave the tree standing in water.

How to tell olive tree needs repotting

Repotting on a calendar is less reliable than reading the plant. For olive tree, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot olive tree

Every 2–3 years, into bone-dry mix. Olive Tree's growth habit — slow-growing, much-branched evergreen tree or large shrub with a gnarled trunk and narrow silver-backed leaves. long-lived, drought-hardy, and very amenable to pruning, pot culture, and topiary. — sets the pace.

What size pot to step olive tree up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Olive Tree stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot olive tree

Spring or summer, while olive tree is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting olive tree

Repot dry. Do not water olive tree for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty sharply free-draining, neutral to alkaline; stony or sandy ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set olive tree at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep olive tree completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for olive tree

Olive Tree wants sharply free-draining, neutral to alkaline; stony or sandy. Thrives in poor, gritty, even chalky soils, but rots in heavy wet ground. Plant in raised or sloping sites; for pots use a loam-based mix (John Innes No.2/3) cut with extra grit or perlite. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting olive tree — frequently asked questions

How often should you repot olive tree?

Every 2–3 years, into bone-dry mix for olive tree. Repot olive tree every 2–3 years into a snug pot of sharply free-draining, neutral to alkaline; stony or sandy, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does olive tree need?

When is the best time of year to repot olive tree?

Should you water olive tree after repotting?

No — not straight away. Repot olive tree into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise olive tree after repotting?

Not immediately. Wait about 3 weeks after repotting olive tree. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
