Oaks grow well in coves and on middle and lower slopes facing north or east. Timber growth rate and quality are generally best on sites with silt, loam or clay soil at least 3 feet deep, that is moderate- to well-drained. Tree growth and quality is poorest on sites with soil less than 20 inches deep or deep porous sands. Oaks also grow poorly on narrow ridges, upper slopes and steep slopes facing south and west. Oaks regenerate easily on poor sites, but are difficult to regenerate on good sites, because they must compete with many other tree species. Here are some points to consider when regenerating oaks.
