The Pee Gee Hydrangea, short for “Paniculata Grandiflora,” is a cultivar of the panicle hydrangea species.

This deciduous shrub typically grows to a height and spread of 10-20 feet, making it a substantial presence in any garden.

Growing and Caring for Pee Gee Hydrangea

Planting

To ensure the best start for your Pee Gee Hydrangea:

1. Choose a location with full sun to partial shade.
2. Prepare well-draining soil enriched with organic matter.
3. Dig a hole twice the width of the root ball and at the same depth.
4. Place the plant in the hole, backfill with soil, and water thoroughly.

Watering

Pee Gee Hydrangeas prefer consistently moist soil but can tolerate brief dry spells once established. Water deeply once or twice a week, especially during hot, dry periods.

Fertilizing

Apply a balanced, slow-release fertilizer in early spring before new growth begins. Avoid over-fertilizing, as this can lead to lush foliage but fewer flowers.

Pruning

One of the great advantages of Pee Gee Hydrangea is its flexibility in pruning:

• For a shrub form: Prune in late winter or early spring before new growth appears.
• To train as a tree: Select the strongest stem as the main trunk, remove lower branches, and shape the canopy as desired.

How to prune pee gee hydrangea into a tree

1. Choose a Strong Central Leader

• In the first year or during planting, identify the strongest, straightest stem (called the central leader). This will become the main trunk.
• Remove all other stems at the base to focus energy on this central leader.

2. Support the Trunk

• Stake the central leader to help it grow straight. Use a sturdy stake and tie the stem loosely to allow for some movement but provide support.

3. Remove Lower Branches

• As the central leader grows, prune off lower branches to a height where you’d like the canopy to begin, usually around 3-4 feet (0.9–1.2 meters) from the ground. This creates a tree-like appearance.

4. Shape the Canopy

• Once the trunk has reached the desired height, let the top branches grow to form the canopy. Prune these branches to encourage a balanced, rounded shape.
• Always cut just above a healthy bud or leaf node.

5. Annual Pruning

• Each year, prune in late winter or early spring before new growth begins. Remove any crossing branches, suckers (new shoots from the base), or dead wood.
• Shape the canopy by cutting back branches to maintain a rounded, even shape.

6. Maintenance

• Continue to remove any suckers or shoots that grow from the base or along the trunk throughout the growing season.
• Over time, the trunk will become thicker, and the tree shape will become more pronounced.

The Pee Gee Hydrangea is a magnificent addition to any garden, offering stunning blooms, versatility, and relatively easy care. Whether you choose to grow it as a majestic shrub or an elegant small tree, this hydrangea variety will undoubtedly become a focal point in your landscape.
