Hydrangea is planted as a potted plant.

Planting Potted Plants in the Garden:

  • Hydrangeas may be planted in partial shade or in full sun. In the south shade is better for them. In the north full sun is better. Some varieties are more tolerant of sun than others. Select a location with soil rich in organic matter. Avoid planting too close to trees which will compete with them for moisture.
  • Prepare the bed by turning the soil under to a depth of 6-12, inches removing any debris, and lightly raking as level as possible.
  • The addition of organic matter (leaf mold, compost, well-rotted manure) benefits all gardens and is essential in recently constructed neighborhoods.
  • Plant on a cloudy day or in late afternoon to reduce transplant shock.
  • Dig a hole for each plant large enough to amply accommodate the root ball.
  • Unpot the plant and gently loosen the root ball with your hands to encourage good root growth.
  • Place the top of the root ball even with the level of the surrounding soil. Fill with soil to the top of the root ball. Press soil down firmly with your hand.
  • Use the plant tag as a location marker.
  • Thoroughly water and apply a light mulch layer on top of the soil (1-2 inches) to conserve water
  • Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their germination. 
  • Mulches also help retain soil moisture and maintain even soil temperatures. For perennials, an organic mulch of aged bark or shredded leaves lends a natural look to the bed and will improve the soil as it breaks down in time.  Always keep mulches off a plant’s stems to prevent possible rot.
  • Careful watering is essential in getting perennials off to a good start. Water thoroughly at least once a week to help new roots grow down deeply. Soil should be damp at about 1 inch below the soil surface. You can check this by sticking your finger in the soil. Water early in the morning to give all leaves enough time to dry.  One inch of rain or watering per week is recommended for most perennial plants. You can check to see if you need to add water by using a rain gauge.
  • After new growth appears, a light fertilizer may be applied. Keep granular fertilizers away from the plant crown and foliage to avoid burn injury. Use low rates of a slow release fertilizer such as Garden-tone, as higher rates may encourage root rots.
  • “Deadhead”, remove spent flower heads just below the inflorescence (the cluster of flowers) to encourage continuous flowering and prevent seed development. The flowers of some varieties dry nicely on the plant.
  • In colder regions, apply another layer of mulch (1-2 inches) after the ground freezes in fall. Evergreen boughs (from Christmas trees) provide additional protection. Remove this mulch in the spring.

Hydrangeas make beautiful cut flowers and add a nice touch to borders. Many varieties are also great for containers.

Pruning is very important and will vary depending on the species of the plant:

Hydrangea quercifolia (Oak Leaf Hydrangea) bloom on last year’s wood, only prune any pruning that needs to be done is just to control height. Prune right after it is finished blooming or just remove the dead flowers.

Hydrangea macrophylla (Big Leaf Hydrangea): This species blooms on last year’s wood. Any pruning that needs to be done is just to control height. Prune right after it is finished blooming or just remove the dead flowers.

Hydrangea serrata ( Mountain Hydrangea): This blooms on last year’s wood. Prune right after it has finished blooming or just remove the dead flowers.

Hydrangea paniculata (Peegee Hydrangea): This blooms on this year’s wood. Prune in early spring before new growth starts.  For the largest flowers, thin to 5-10 primary shoots. Note that the weight of the flowers can cause the branches to arch downward.

Hydrangea arborescens (Hills of Snow Hydrangea): This blooms on this year’s wood. Prune in early spring before new growth starts. Hills of Snow hydrangea may be left unpruned (except for removing dead branches). In this case it will produce many smaller clusters of flowers.

Hydrangea, Paniculata Unique is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Love this hydrangea! These bloomed in the pot, even before I planted them. Nice blooms pretty enough to cut. I'm excited to see what they do in years to come.

Rated 5 out of 5 by from beautiful I bought 3 and they grew 3 feet and bloomed nicely the first year. I pruned them into tree form and they didn't suffer all.
