About Fertility pear
Pyrus communis 'Fertility' · also called Fertility pear, Fertility Improved pear · edible
An old English dessert and dual-purpose pear cultivar, 'Fertility' is notable for being partially self-fertile — useful in smaller gardens where space for multiple pollinators is limited. It bears medium-sized, russet-tinged fruits with sweet, juicy flesh ripening in September–October. Reliable, heavy-cropping, and tolerant of a range of soils and aspects.
Preferred mix: Fertile, moisture-retentive, well-drained loam
Watch for — Pear midge (Contarinia pyrivora): Fruitlets turn black and fall early in June; larvae feed inside. Cultivate soil under the tree in winter to expose pupae to frost and birds. Apply a suitable insecticide (deltamethrin) at white-bud stage if infestation was severe the previous year.
Why fertility pear needs this mix
Fertility pear hates drying out, so it wants a mix that stays evenly moist — but it still needs perlite so "moist" never tips into "waterlogged".
- Fertility pear comes from damp, shaded forest floors and has fine roots that scorch and brown the moment the rootball dries — the mix has to hold a steady reserve.
- Coir and compost give that reserve, while perlite keeps enough air that the constantly-moist mix does not turn anaerobic.
- Even moisture also keeps its thin leaves from crisping at the edges, which is this plant’s most visible stress signal.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons fertility pear struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A free-draining, gritty mix dries too fast for fertility pear — you get crispy brown edges and frond or leaf drop within days of one missed watering.
- A pure, airless peat mix swings the other way: it holds water but suffocates the fine roots and rots the crown.
- Letting the mix dry to the point it shrinks from the pot is very hard to re-wet evenly and stresses the plant badly.
Using a sharp, fast-draining "houseplant" or cactus-leaning mix that lets fertility pear dry out. It needs a moisture-retentive but still airy blend.
pH — does it matter for fertility pear?
Fertility pear prefers a slightly acidic mix (around pH 5.5-6.5); a peat-free compost-and-coir blend sits there naturally, so routine pH testing is unnecessary.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good peat-free houseplant compost works for fertility pear straight from the bag if you mix in some perlite for air. The DIY ratio above gives a more reliable moisture-to-air balance.
Drainage and the pot
Use a pot with a drainage hole but a less-porous material (plastic or glazed) so it does not dry too fast. Bottom-watering keeps the mix evenly moist without sogging the crown.
Peat-free mixes slump and compact as they hold moisture, so refresh fertility pear's mix every 12-18 months to keep air in the rootball even if the pot size is unchanged. When the time comes, our repotting guide for fertility pear covers the timing and technique step by step.
