Green Giant Arborvitae Care

Planting: Choose a location with well-drained soil and full to partial sunlight. Green Giant Arborvitae can tolerate a variety of soil types but prefer slightly acidic, moist soil. Plant them with enough space between each tree to accommodate their mature size.

Watering: Keep the soil consistently moist, especially during the tree’s establishment period and dry spells. Water deeply and infrequently, allowing the soil to dry slightly between waterings. Avoid overwatering, as it can lead to root rot.

Mulching: Apply a layer of organic mulch around the base of the trees, extending out to the drip line. Mulch helps retain soil moisture, regulate temperature, and suppress weeds. Keep the mulch a few inches away from the trunks to prevent rot.

Fertilizing: Green Giant Arborvitae generally don’t require heavy fertilization. However, you can apply a balanced, slow-release fertilizer in spring to provide nutrients. Follow the manufacturer’s instructions for application rates.

Pruning: Minimal pruning is needed for Green Giant Arborvitae. Remove any dead, damaged, or diseased branches as needed. Prune to maintain the desired shape and size, but avoid heavy pruning, as it may affect the tree’s natural form.

Protection: Protect young trees from harsh weather conditions, strong winds, and extreme temperatures. Consider using tree wraps or shelters to shield them during winter.

Pest and Disease Control: Monitor for common pests like spider mites, bagworms, and aphids, as well as diseases like canker and root rot. Treat infestations promptly with appropriate insecticides or fungicides.

Winter Care: Green Giant Arborvitae are generally hardy, but providing some winter protection, such as wrapping the trees with burlap or applying anti-desiccant sprays, can help prevent winter damage.
