About Pawpaw 'Susquehanna'
Asimina triloba 'Susquehanna' · also called Susquehanna pawpaw · edible
'Susquehanna' is a Peterson pawpaw selection famous for very large fruit, thick buttery flesh and notably few, small seeds. This hardy deciduous understorey tree of eastern North America crops in temperate gardens but needs a second, genetically different cultivar to pollinate it. Give young trees light shade, mature trees full sun, and deep, moist, well-drained soil.
Preferred mix: Deep, fertile, well-drained loam
Watch for — Fruit drop in drought: Heavy fruit aborts if soil dries; water deeply in dry spells and mulch to hold moisture.
Why pawpaw 'susquehanna' needs this mix
Pawpaw 'Susquehanna' is a hungry, thirsty crop — it wants a rich, moisture-retentive but free-draining loam, well fed and never baked dry.
- Pawpaw 'Susquehanna' grows fast and has a big crop to fill, so it draws heavily on both nutrients and water — a lean mix simply cannot keep up.
- Plenty of organic matter holds moisture evenly, which prevents the stress problems (bolting, bitterness, blossom-end rot) that come from a drying-then-flooding cycle.
- It still needs structure: rich does not mean airless, so grit, perlite or leaf mould keeps roots oxygenated.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons pawpaw 'susquehanna' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- A poor, thin or sandy mix starves pawpaw 'susquehanna' — growth stalls, leaves pale, and yields collapse.
- A heavy, compacted, badly drained soil rots the roots and brings fungal problems despite all the feeding.
- Letting a rich mix dry to dust then drowning it causes the classic moisture-stress disorders this crop is prone to.
Under-feeding and inconsistent moisture. Pawpaw 'Susquehanna' needs genuinely rich soil plus steady watering — most disappointing crops come down to one or both being short.
pH — does it matter for pawpaw 'susquehanna'?
Pawpaw 'Susquehanna' does best around pH 6.0-7.0 (slightly acidic to neutral). It is worth a cheap soil test for an outdoor bed; very acidic soil benefits from a little lime well before planting.
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
For containers a good multipurpose or vegetable compost works for pawpaw 'susquehanna' with extra feed through the season. For beds, the real win is digging in plenty of well-rotted compost or manure — that beats any bag.
Drainage and the pot
Rich but free-draining is the target: raised beds and large containers both deliver it. Mulch heavily to even out moisture and roughly halve how often you water.
