About Navel orange

Citrus sinensis 'Navel' · also called Navel orange, Washington navel · edible

Navel orange is a seedless, sweet dessert orange recognised by the small secondary fruit ('navel') at the blossom end. It ripens in winter–spring and is prized for fresh eating. Full sun, well-drained slightly acidic soil, and a long warm season are essential. Dwarf grafted forms suit containers and patios in cool climates.

Mature size: In ground: 4–6 m tall, 3–5 m spread; dwarf container form: 1.5–2 m tall

Indoor size vs how big it gets in the wild

Navel orange is a tree at heart. Indoors a pot and your ceiling keep it to in ground: 4–6 m tall, 3–5 m spread, but in the ground it is a different scale of plant entirely (dwarf container form: 1.5–2 m tall). Indoors and in a pot, expect in ground: 4–6 m tall, 3–5 m spread. In the ground with no restriction it is a completely different plant — dwarf container form: 1.5–2 m tall — which is why the pot, the light and the pruning matter so much for the size you actually end up with.

It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Growth rate and years to mature

Navel orange is a fast grower. Realistically, expect two to four years from a young plant to a room-filling specimen in good light. Its feeding profile backs this up: apply a specialist citrus or slow-release fertiliser (high in nitrogen with added magnesium and iron) monthly from february to september. navel oranges are prone to magnesium deficiency causing leaf yellowing; epsom salts (magnesium sulfate) foliar spray corrects mild cases.

How to keep navel orange smaller

You are not stuck with the maximum size. For navel orange specifically, these are the levers, in order of impact:

The decisive tool is the secateurs: navel orange can be topped (cut the main growing tip) to cap its height and force a bushier, shorter shape.
Keeping it deliberately pot-bound in a snug container slows the whole plant and limits ultimate size.
Prune in spring so it heals fast; remove the tallest leader back to a node to reset the height.
Expect to top or hard-prune it every year or two — left alone it heads for the ceiling.

The keep-it-smaller method, step by step

Pick the new height. Decide how tall you want navel orange and find a leaf node or branch point just below that.
Top the main stem. Cut the main growing tip cleanly just above that node in spring; this permanently caps the height and forces side branches.
Keep the pot snug. Avoid jumping to a much bigger pot — a slightly restricted rootball keeps the whole plant smaller.
Maintain the shape. Prune back the tallest new leaders each spring to hold it at the height you chose.

How to grow navel orange bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for navel orange the accelerators are:

It already wants the bright light it needs; warmth, a yearly pot-up and spring-summer feed are the accelerators.
Pot up a size every year or two while young; restricted roots are the main thing holding height back.
Feed regularly through the growing season and keep it warm — height comes from sustained good conditions.

Light is almost always the ceiling. The navel orange light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When navel orange outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for navel orange:

The top leaves pressing against or bent by the ceiling — the classic "this is now too tall indoors" sign.
It has to be moved away from a light source it has literally outgrown.
Roots filling the largest pot you can reasonably keep indoors — at that point it is top-or-prune or move it outside (if hardy).

If it is the pot rather than the room, it is a repotting job, not a goodbye — see the navel orange repotting guide. If you want more of this plant instead of a bigger one, the navel orange propagation guide turns prunings into new plants.

Navel orange size — frequently asked questions

How big does navel orange get?

Navel orange reaches in ground: 4–6 m tall, 3–5 m spread when grown indoors, and far larger where it grows unrestricted (dwarf container form: 1.5–2 m tall). It gains real height on a trunk or main stem, adding a tier of leaves a year and eventually reaching for the ceiling — this is a plant you grow up, not out.

Is navel orange slow or fast growing?

Navel orange is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Navel orange is a tree at heart. Indoors a pot and your ceiling keep it to in ground: 4–6 m tall, 3–5 m spread, but in the ground it is a different scale of plant entirely (dwarf container form: 1.5–2 m tall).

How long does navel orange take to reach full size?

Roughly two to four years from a young plant to a room-filling specimen in good light. Light, pot size and feeding move that timeline more than anything else.
