Although some evergreens are drought-tolerant, most need a lot of water. Evergreens need one inch of water per week even in the late fall. Water with a sprinkler or hose if there isn't enough rain. Add mulch around the evergreen to conserve water.

Most evergreens need well-drained soil. The American arborvitae, balsam fir and black spruce do well in wet areas. Many conifers prefer a medium soil, not too sandy and not too much clay. Sandy soil is good for mugho and Scotch pine. Arborvitae and white fir can be grown in clay. Broad-leaved evergreens need acidic soil.

The best times to plant evergreens are early spring when the ground is workable or in the fall. In cold climates the last time you should plant an evergreen is six weeks before winter begins. Check with your county extension office to find the best time to plant evergreens in your area.

Most evergreens benefit from light trimming and pruning each year. This will keep their shape and allow them to grow. Evergreens should be pruned early in the spring before new growth starts or just after.

Almost all evergreens need to be planted in full sun or partial shade. Exceptions such as Canadian yew and the Japanese hemlock like shady areas.

Fertilize every two to three years using fertilizer formulated for acid or alkaline-loving evergreens. Use your judgment. If the evergreen isn't growing enough or foliage color is lacking, it should be fertilized.

Tips & Warnings
To know if your evergreen needs to be watered, leave an empty tuna can by the plant. If rain hasn't filled it, you need to water. Your county extension office will have information on your specific evergreen.
Don't fertilize a broad-leaved evergreen too much because its roots can be easily burned.
