Pests in Gardens and Landscapes

Pine cones

Pine—Pinus spp.
Family Pinaceae (Pine family)

Plant identification

Optimum conditions for growth

Pines grow in several climatic zones varying by species. Plants do well in areas with full sun, and most species need little water once established. They do best in relatively well-drained soils.
