Light: Prefers full sun
Shade: Some species tolerate light shade (J. communis) but most do not
Moisture: Medium soil moisture preferred, but these are very resistant to drought
pH: most species prefer fairly neutral to alkaline soil (6.1 – 8.0), but it can grow if very acidic to very alkaline soils.
Special Considerations for Growing:
It is likely that all species tolerates juglone (natural growth inhibitor produced by Black Walnut and its relatives). Consider using this tree as a buffer between your walnuts and other plantings.
Easily from seed. Seeds need about 6 months stratification for germination, which can be slow. Can be grown from cuttings taken in Spring. May develop roots from branches that are buried which can later be divided from the mother plant.
Weeding around the plant is needed for the first few years in the slower growing species. After that, not much maintenance is needed.
- Many species are very intolerant to fires… meaning they spread forest fires well. This also means it is a pretty good fuel wood.
- Some people can have seasonal allergies to the pollen.
- Some species can spread too easily from seeds (mainly by birds) and can become locally invasive.
