About Comice pear

Pyrus communis 'Comice' · also called Comice pear, Doyenné du Comice · edible

Widely regarded as the finest-flavoured dessert pear, producing large, round, greenish-yellow fruits with exceptionally juicy, buttery, richly perfumed flesh. Requires a warm, sheltered position to ripen well. Crops moderately; needs a compatible pollination partner. Holds the RHS Award of Garden Merit.

Mature size: On Quince A: 3.5–4.5 m (12–15 ft); on Quince C: 2.5–3 m (8–10 ft)

Watch for — Fireblight (Erwinia amylovora): Bacterial shoot blight; symptoms include wilting, blackening and a scorched appearance. Cut well below infection with sterilised tools. No curative treatment; avoid lush, nitrogen-rich growth that is most vulnerable.

Indoor size vs how big it gets in the wild

Comice pear is a tree at heart. Indoors a pot and your ceiling keep it to on quince a: 3.5–4.5 m (12–15 ft), but in the ground it is a different scale of plant entirely (on quince c: 2.5–3 m (8–10 ft)). Indoors and in a pot, expect on quince a: 3.5–4.5 m (12–15 ft). In the ground with no restriction it is a completely different plant — on quince c: 2.5–3 m (8–10 ft) — 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

Comice pear 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: feed with a balanced fruit-tree fertiliser at bud-break in early spring. apply sulphate of potash in late summer to enhance fruit sugar levels and skin colour. annual compost mulch around the root zone is strongly recommended. avoid high-nitrogen feeding after midsummer.

Want this turned into the right next pot at the right moment? The pot size calculator and the comice pear repotting guide cover when and how much to size up — pot size is one of the biggest levers on how fast comice pear grows.

How to keep comice pear smaller

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

The decisive tool is the secateurs: comice pear 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 comice pear 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 comice pear bigger or faster

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

When comice pear outgrows the room (or the pot)

"Too big" usually arrives as one of these signs for comice pear:

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

Comice pear size — frequently asked questions

How big does comice pear get?

Comice pear reaches on quince a: 3.5–4.5 m (12–15 ft) when grown indoors, and far larger where it grows unrestricted (on quince c: 2.5–3 m (8–10 ft)). 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 comice pear slow or fast growing?

Comice pear is a fast grower. Expect two to four years from a young plant to a room-filling specimen in good light. Comice pear is a tree at heart. Indoors a pot and your ceiling keep it to on quince a: 3.5–4.5 m (12–15 ft), but in the ground it is a different scale of plant entirely (on quince c: 2.5–3 m (8–10 ft)).

How long does comice pear 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.
