What Are Conical Hydrangeas?

Conical hydrangeas (Hydrangea paniculata) are a type of deciduous shrub native to Asia and North America. They are valued for their showy, cone-shaped flower clusters that bloom in mid- to late summer. Unlike other hydrangea varieties, conical hydrangeas can be trained into tree form, making them a versatile addition to any landscape.

There are several popular varieties of conical hydrangeas, each with its own unique characteristics:

'Limelight': This variety is known for its large, lime-green flowers that turn pink as they mature.
'PeeGee': Also known as Pee Gee hydrangeas, these plants have long, pointed blooms and can be trained into tree form.

Planting and Care

Location

Conical hydrangeas prefer well-drained soil and full sun to partial shade. When choosing a location for your plant, look for an area with good air circulation and plenty of space for the plant to grow.

Planting

To plant a conical hydrangea, follow these steps:

Dig a hole twice as wide as the root ball, but no deeper.
Loosen the roots and place the plant in the hole.
Backfill with soil and water thoroughly.

Watering

Conical hydrangeas require regular watering, especially during hot, dry weather. Be sure to water deeply, saturating the soil around the plant's roots.

Fertilizing

Fertilize your conical hydrangea in early spring with a balanced fertilizer. Avoid using high-nitrogen fertilizers, which can cause excessive foliage growth at the expense of blooms.

Pruning

Conical hydrangeas should be pruned in late winter or early spring before new growth begins. Remove any dead, damaged, or diseased wood, and trim back the previous year's growth to 2-3 buds. If you're growing your hydrangea as a tree, prune off any lower branches to create a clear trunk.

Pests and Diseases

Pests

Conical hydrangeas are relatively pest-resistant, but they may be susceptible to aphids, spider mites, and scale insects. Treat with insecticidal soap or neem oil as needed.

Diseases

Common diseases that can affect conical hydrangeas include powdery mildew, leaf spot, and root rot. To prevent these issues, avoid overhead watering and make sure the plant has good drainage.
