Complete Care & Growing Guide

Light Requirements

Requires full sun for optimal growth, canopy development, and overall health.

Soil

Prefers well-drained soil but adapts to a wide range, including clay and wetter soils. Tolerates both slightly acidic and alkaline conditions.

Watering

Water regularly during establishment. Once established, it is moderately drought tolerant but performs best with consistent moisture.

Pruning

Prune in late winter to maintain structure and remove dead or crossing branches. Its natural upright form typically requires minimal shaping.

Uses & Landscape Benefits

Regal Prince® Oak is ideal for street plantings, narrow lawns, and urban environments due to its upright growth habit. It works well as a shade tree in smaller spaces, providing vertical structure without spreading too wide. Its durability also makes it suitable for commercial landscapes, parks, and residential properties.

Planting & Care

1. Planting: This is a large landscape tree and as such, requires a bit of planning before planting. First, measure the area where you would like to plant your hedge or row. You will need the length of the area of planting to estimate the number of trees you need.

When planting, dig a hole for each tree that is three times as wide as the root ball but just as deep. Place the tree, fill in around the tree with the same soil you took out when initially digging the hole. Finally, tamp down as you fill to cut back on any air pockets from forming, water the tree, then mulch to conserve moisture.

2. Watering: For the first two weeks, water your new tree every other day by holding a hose around it and counting to 20. If you don’t have a hose, 2 large watering cans full of water will do (smaller trees may only need a light soaking so a single can may suffice).
