Best Fertilizer for Norway Spruce Windbreaks

Fertilizing Norway Spruce for a Healthy Windbreak

Norway spruce makes an excellent windbreak, but proper fertilization ensures dense, vigorous growth. The top recommendation from experienced growers is Holly-tone by Espoma—an organic, granular fertilizer ideal for acid-loving evergreens.

Application Schedule

• Early spring – as new growth begins
• Early fall – before dormancy

Sprinkle 1–2 coffee cupfuls under the drip line of each tree. Rain will gradually carry nutrients into the root zone. Holly-tone also benefits other acid-loving plants like hollies and dogwoods.

Pruning for Uniform Appearance

While young, keep all trees in the row roughly the same size and shape. During the holiday season (November–December), trim back long branches to maintain a conical form. The cuttings can be used for seasonal decorations.

Where to Buy

Holly-tone is available at local garden centers and nurseries in 5, 10, 25, 35, and 50 lb bags. Choose the size that matches your planting scale.
