15' 25' wide. Slow to medium Useful as a specimen and good in hedges in formal and semi- formal plantings. Numerous cultivars are available. Tsuga - Hemlock Hemlocks generally grow to be graceful pyramidal trees, which retain their attractive character into old age. If grown in full sun, hemlocks require good drainage and plenty of organic matter in the soil.
Hemlocks are excellent for hedges and screens, groupings and accents.
They will tolerate clay soil, as long as it does not remain waterlogged, but grow best in well-drained, moist, acidic soil. They will withstand heavy pruning, best done in spring or summer. Sweeping winds dry out the foliage, so hemlocks are not suitable for windswept sites. Mulch to retain soil moisture, and water regularly during dry periods.
