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)

How to tell comice pear needs repotting

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

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot comice pear

Pot on seedlings as they grow; not a perennial repot. Comice pearis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Moderately vigorous, spreading deciduous tree; spur-bearing; suitable for trained forms (espalier, cordon, fan) or open-centred bush.

What size pot to step comice pear up to

Pot comice pear on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot comice pear

Pot comice pear on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting comice pear

  1. Pot on before it is root-bound. Check comice pear regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
  2. Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
  3. Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
  4. Pot into rich mix. Set it into fresh deep, fertile, moist but well-drained neutral loam at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
  5. Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water comice pear in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for comice pear

Comice pear wants deep, fertile, moist but well-drained neutral loam. Needs a rich, deep soil with a pH of 6.0–7.0. Avoid shallow chalk, strongly acidic or waterlogged soils. Comice is less tolerant of poor soils than some other cultivars. Annual mulching with compost is beneficial. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting comice pear — frequently asked questions

How often should you repot comice pear?

Pot on seedlings as they grow; not a perennial repot for comice pear. Comice pear is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into deep, fertile, moist but well-drained neutral loam so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does comice pear need?

Pot comice pear on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check. Use our pot size calculator to size it from the plant's current pot and root spread.

When is the best time of year to repot comice pear?

Pot comice pear on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Can you put comice pear straight into a much bigger pot?

No. Even a fast-growing comice pear should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise comice pear after repotting?

Not immediately. Wait about 1 week after repotting comice pear. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
