Planting and Care Tips
Choosing the Right Location

Planting Process
- Dig a hole twice as wide as the root ball and equally deep
- Place the tree at the same depth it was in the container
- Backfill with native soil, tamping gently to remove air pockets
- Water thoroughly after planting
Watering
- Water deeply and regularly during the first growing season
- Once established, most species are drought-tolerant but benefit from occasional deep watering during dry spells
Fertilizing
- Apply a slow-release, balanced fertilizer in early spring
- Avoid over-fertilizing, which can lead to excessive growth and weak structure
Pruning
- Most tall, thin evergreens require minimal pruning
- Remove dead or damaged branches as needed
- Light shaping can be done in late winter or early spring
