About Pineapple guava

Feijoa sellowiana · also called Pineapple guava, Feijoa · edible

An evergreen shrub bearing pineapple-mint-flavored fruit, pineapple guava thrives in full sun with well-drained soil. Hardy to around 15°F (-9°C), it suits zones 8–11 and warmer UK coastal gardens. Water regularly during fruit development, fertilize lightly, and shelter from harsh winds for best harvests.

Mature size: 1.5–2.5 m tall and wide (5–8 ft); can be grown larger in optimal conditions or kept compact by pruning

Indoor size vs how big it gets in the wild

Pineapple guava is a tree at heart. Indoors a pot and your ceiling keep it to 1.5–2.5 m tall and wide (5–8 ft), but in the ground it is a different scale of plant entirely (can be grown larger in optimal conditions or kept compact by pruning). Indoors and in a pot, expect 1.5–2.5 m tall and wide (5–8 ft). In the ground with no restriction it is a completely different plant — can be grown larger in optimal conditions or kept compact by pruning — 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

Pineapple guava 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 balanced fertilizer (e.g., 8-8-8 npk) every 6–8 weeks during the growing season in spring and summer. use approximately half the recommended dose for tree/shrub size. trace elements (iron, magnesium, zinc) benefit fruit production. avoid heavy nitrogen feeds, which promote foliage at the expense of fruit.

How to keep pineapple guava smaller

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

The decisive tool is the secateurs: pineapple guava 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 pineapple guava 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 pineapple guava bigger or faster

If you want it to fill the space sooner, push the conditions rather than hoping — for pineapple guava 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 pineapple guava light requirements page covers exactly how bright a spot it needs to grow at its potential instead of stalling.

When pineapple guava outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for pineapple guava:

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 pineapple guava repotting guide. If you want more of this plant instead of a bigger one, the pineapple guava propagation guide turns prunings into new plants.

Pineapple guava size — frequently asked questions

How big does pineapple guava get?

Pineapple guava reaches 1.5–2.5 m tall and wide (5–8 ft) when grown indoors, and far larger where it grows unrestricted (can be grown larger in optimal conditions or kept compact by pruning). 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 pineapple guava slow or fast growing?

Pineapple guava is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Pineapple guava is a tree at heart. Indoors a pot and your ceiling keep it to 1.5–2.5 m tall and wide (5–8 ft), but in the ground it is a different scale of plant entirely (can be grown larger in optimal conditions or kept compact by pruning).

How long does pineapple guava 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.
