Pears

Grow Your Own: Pears (From Suckers – Rare but Possible)

Pear trees are not known for producing suckers the way apples, plums or hazel do. Most pears grow on a single trunk and stay politely in their lane. But under the right conditions: stress, damage, grafted rootstock behavior or certain species traits, a pear tree can send up suckers from the base or roots.

These suckers can sometimes be grown into new pear trees. But the outcome depends entirely on what part of the tree the sucker came from. This page explains the logic, the method and the expectations.

What is a sucker?

A sucker is a shoot that emerges from:

  • the base of the tree
  • the roots
  • the rootstock (if the tree is grafted)

It is genetically identical to the part of the tree it came from, but that part may not be the fruiting variety.

This is the key.

The critical question:

Is the pear tree grafted or seed‑grown?

This determines everything.

✔ If the tree is seed‑grown

A sucker will be genetically identical to the tree itself. You can grow it into a new pear tree with the same traits.

✖ If the tree is grafted

The sucker comes from the rootstock, not the fruiting variety.

This means:

  • the sucker will NOT produce the same fruit
  • the sucker may produce small, hard, wild‑type pears
  • the sucker may be ornamental only
  • the sucker may be extremely vigorous (rootstock traits)

This is the most common scenario.

✔ If the tree is wild or feral

Suckers are normal and grow true.

✔ If the tree is Asian pear (Pyrus pyrifolia)

Some varieties sucker more readily.

When do pear trees produce suckers?

Pears rarely sucker unless:

  • the trunk is damaged
  • the graft union is stressed
  • the tree is under drought stress
  • the roots are disturbed
  • the tree is very old
  • the rootstock is a suckering species
  • the tree is cut down (suckers emerge from surviving roots)

Suckers are a stress response more than a normal growth habit.

Can you grow a new pear tree from a sucker?

Yes, but you should understand what you’re getting.

✔ If the sucker is from a seed‑grown tree

You get a clone of the parent tree. Fruit will match the parent.

✔ If the sucker is from a wild pear

You get a wild pear. Fruit may be small, firm, tannic or excellent for cooking.

✖ If the sucker is from a grafted tree

You get the rootstock variety. Fruit will NOT match the parent.

Rootstock pears are often:

  • extremely hardy
  • extremely vigorous
  • extremely disease‑resistant
  • producing small, hard, astringent fruit

They are useful, but not dessert pears.

How to remove and root a pear sucker

Step 1: Identify the sucker

Look for shoots emerging:

  • from the soil near the trunk
  • from exposed roots
  • below the graft union (a swelling on the trunk)

Step 2: Dig carefully

Use a trowel to expose:

  • the base of the sucker
  • the point where it connects to the root
  • any small roots it has formed

Step 3: Sever cleanly

Use sharp pruners to cut the sucker away with:

  • a small section of root
  • or a heel of bark

This increases success.

Step 4: Pot it up

Plant in:

  • a deep pot
  • well‑draining soil
  • bright, indirect light

Step 5: Keep evenly moist

Not soggy. Not dry.

Step 6: Harden off and plant out

After 6–12 weeks of stabilization.

What to expect from a sucker‑grown pear tree

Growth

Suckers are often:

  • vigorous
  • fast‑growing
  • eager to establish

Fruit

Depends entirely on origin:

  • seed‑grown parent: identical fruit
  • wild parent: wild fruit
  • grafted parent: rootstock fruit (variable, often not dessert quality)

Pollination

Same rules as all pears:

  • pears are self‑incompatible
  • need a genetically different partner
  • bloom time must overlap

A sucker from a grafted tree will NOT pollinate the grafted top. They are genetically different.

Wildlife and orchard ecology

A sucker‑grown pear tree will attract:

Pollinators

  • bees
  • hoverflies
  • early spring insects

Birds

  • robins
  • starlings
  • cedar waxwings
  • woodpeckers

Mammals

  • deer (protect young trees)
  • squirrels
  • raccoons

Insects

  • leafrollers
  • aphids
  • caterpillars
  • pear psylla (regional)

Even a rootstock pear is a valuable wildlife tree.

Common problems

Sucker dies after removal

Cause: too few roots, transplant shock.

Sucker wilts

Cause: too much sun too soon.

Sucker grows but never fruits

Cause: rootstock genetics.

Suckers keep returning

Cause: grafted tree under stress.

Seasonal rhythm

Spring: Best time to remove suckers.

Summer: Rooting and stabilization.

Autumn: Plant out in mild climates.

Winter: Protect young trees from frost.
