A ripe pear off your own tree, melting on the tongue, is a different fruit from the hard stuff on the shelf. Yet the pear has a reputation for being a little trickier than the apple, and that is even true: it wants more warmth, flowers earlier and is fussy about pollination.
Anyone who bears these three points in mind from the start has little trouble. This article shows you what matters for spot, rootstock and pollinator, so the little tree becomes a bearing one.
The spot: pears want warmth
The pear comes from warmer regions than the apple and shows it in the garden. In a full-sun, sheltered spot the fruit ripens better and turns sweeter. The classic is the espalier against a south- or west-facing wall: the masonry stores heat, brings the harvest forward and protects the blossom.
Because pears flower early, often as soon as April, they are more at risk from late frost than apples. A warm, slightly raised spot where cold air does not pool is therefore worth its weight in gold.
The pollination puzzle
Here lies the most common reason for a pear tree that flowers year after year but barely bears: it lacks the right partner. Almost all pears depend on a second variety that flowers at the same time and matches genetically. And unlike the apple, not every variety harmonises with every other.
How to solve pollination
- Match the flowering time
The pollinator must flower at the same time. Nurseries state for each variety which partners suit. Go by that.
- Use proven pairs
'Conference' and 'Williams Christ' pollinate each other well and are themselves reliable pollinators for many other varieties.
- The neighbourhood counts
The partner need not stand in your own garden. A pear in a neighbour's garden within bee-flight range is enough.
- In doubt, plant two
If there is no other pear far and wide, set two matching varieties at once. Then you are independent.
The rootstock: small via the quince
On the pear too the rootstock sets the size. On a quince rootstock the tree stays smaller, bears earlier and is easy to pick, the usual choice for the home garden. On heavy, cold or dry soil the quince reaches its limits, and there the vigorous seedling is tougher but becomes a large tree. More on this in Understanding fruit tree rootstocks.
Set it warm, keep it small via the quince, and always think of the pollinator. A pear alone often stays an ornament without fruit.
The core rule on pears
Frequently asked questions
Why does my pear tree not bear although it flowers?
Usually the matching pollinator is missing. Pears almost always need a second variety nearby that flowers at the same time and matches genetically. Without it the blossom drops without setting fruit.
Which pear variety is low-maintenance for the home garden?
'Conference' is considered robust, reliable in cropping and at the same time a good pollinator for other varieties. Combined with 'Williams Christ' or 'Gute Luise' you have a proven, mutually pollinating team.
Does the pear really need a warm wall?
It is not essential, but it helps a lot. Against a south- or west-facing wall the fruit ripens sweeter, and the warmth softens the late-frost risk for the early blossom. Free-standing pears bear too, but need a good, warm spot.
Which rootstock should I choose for a pear?
For the normal home garden the quince: small tree, early cropping, easy to pick. Only on heavy, cold or very dry soil is the vigorous seedling the more reliable, if large, choice.
What can I do about the orange spots on the leaves?
That is pear rust, which shuttles between pear and juniper. The most effective lever is having no susceptible juniper in the vicinity. You can remove individual affected leaves, but against the fungus itself there is little in the home garden.
