Gardener's HQ Guide to Growing the Pawpaw Tree

Asimina triloba is often found growing along streams or in the lower regions of wooded areas, so it makes sense that this tree prefers medium to wet soil.

These trees thrive in partial shade, but they will also tolerate full sun or full shade.

Soils that are high in nutrients and that remain moist are the best choice for these trees, but even sandy or clay type soils will still allow the tree to grow well.

The Pawpaw tree is a hardy plant and is not generally susceptible to diseases or parasites.

Asimina triloba reproduces through cross-pollination, but the tree can also be propagated from its root suckers.

Trees that are located near each other and can cross-pollinate tend to produce more fruit.

So if an overabundance of unwanted fruit is an issue, it may be best to keep only one tree in the garden.
