Roots: Extremely variable based on the species. Many have taproots, some are heart-shaped root masses, and some are a diffuse, fibrous network.
Growth Rate: Most species grow at a Slow to Medium rate; however, a few species are known to grow fast. Also, many of the hybrids grow at a much faster rate.
GROWING CONDITIONS FOR THIS PLANT
Light: Prefers full sun
Shade: Some species tolerate light shade
Moisture: Medium soil moisture preferred, but the “swamp” species (Q. bicolor, Q. michauxii) can handle pretty wet soils as can Q. robur
pH: most species prefer fairly neutral soil (6.0-7.0), and some species (notably Q. macrocarpa) is tolerant of 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.
Propagation:
Easily from seed. Sow immediately in Autumn after the seeds have fallen from the tree.
Maintenance:
Not much maintenance is needed.
Concerns:
Some people can have seasonal allergies to the pollen.
