Podocarpus macrophyllus: Podocarpus1
Introduction
With densely foliated lower limbs which reach the ground and neat, dark green, evergreen leaves, yew podocarpus is very popular as a dense screen or hedge. However, yew podocarpus can reach 30 to 40 feet in height when not sheared and is quite attractive as a tree with the lower branches removed, revealing the light brown, peeling bark. If space permits, leave the lower limbs on the tree for an almost spruce-like appearance. The tree grows in an open manner with large spaces between the branches creating a pleasing, irregular oval silhouette in middle and old age. The inconspicuous flowers are followed by fleshy, purple, small, edible fruits (though the similarly looking seeds are toxic, therefore it is best to avoid ingesting any part of this tree that resembles fruit) on female trees which are quite attractive to birds but not really messy on sidewalks or pavement.

Use and Management
This is one of a few trees which can be pruned into a nice hedge. The dark green foliage and dense growth creates a formal mass. It looks better when pruned with a hand pruner, not sheared with a hedge trimmer.
Showing best growth and form in full sun, yew podocarpus will grow more slowly and have a looser appearance when grown in shade. It will grow on the north side of a tall building with little or no direct sun. It will tolerate a wide variety of well-drained, acidic soils. Don't plant on wet soils. This is a tough tree, adaptable to urban conditions and should be used much more extensively as a street tree. It should be used more in areas of poor soils and restricted rooting space. Unfortunately, most people choose to trim the tree into a column or hedge, so not many have seen the true beauty of the tree. It will make an attractive specimen, street or parking lot tree, even for the smallest soil space in a downtown planting pit. Roots are not a problem in restricted-soil planting areas and usually do not lift sidewalks.
Many varieties are available for selection of habit, leaf form, color, etc. Podocarpus macrophyllus var. angustifolius is a narrow, columnar tree with curved leaves, 2 to 4.5 inches long; Podocarpus macrophyllus var. appressus is a low shrub with short leaves; Podocarpus macrophyllus var. maki has erect branches, columnar form, 1.5 to 3-inch-long leaves.
Propagation is by seeds or cuttings. Hardwood cuttings root easily. Cutting propagation would ensure more uniform trees than seedlings. Nursery operators should be encouraged to grow Yew Podocarpus in the single-trunked tree form for planting in urban landscapes.
Pests and Diseases
No pests or diseases are of major concern. Occasionally bothered by scale, mites, and sooty mold but not seriously. Some magnesium-deficiency on sandy soil, which is easily corrected with magnesium sulfate.
