Incrediball® has the largest snowball flowers of any hydrangea on the market. This improved Annabelle has stronger stems and larger flowers than the original to help in eliminating flopping flower heads. An increased amount of florets and mammoth flowers make this a welcome upgrade on a classic plant for the garden. Our designers suggest using this as a hedge in the landscape or naturalizing it. Throughout summer and fall, it makes for a dramatic cut flower! For the biggest, most abundant blooms and strongest stems, plant them where they will get at least six hours of sun each day. Warmer climates can get away with a bit less. 2022 Proven Winners Landscape Shrub of the Year!

Planting Care
Planting & Care for Incrediball® Hydrangea Plants/Shrubs
Preparation
- These shrubs need damp soil high in organic matter.
- Improve poor soil areas by digging in plenty of well-decayed manure or compost a few months ahead of planting.
- Plant Incrediball® hydrangea between March and November.
- Pick a spot that has dappled sunlight or morning sun and afternoon shade.
- Make sure they are sheltered from frosty winds, which will damage blossoms.
- This plant tolerates a wide range of conditions but does not grow well in soggy soil.
- Plant in full sun in zones 3-9; afternoon shade is preferable in warmer areas.
- Cut the entire plant back by one-third of its height each spring for new growth to emerge.
Opening Plant Material
- Containers: Completely saturate all container plants by putting them in a larger water container until bubbling stops. Remove the plant, then dig a hole no deeper than the depth of the container, ensuring it’s wider on the sides by an additional 6” or more.
Planting Containers
- Hydrangeas can be planted from March to November.
- Dig a hole no deeper than the depth of the container and 6" or wider on the sides.
- Slide the plant from the pot by tapping on the bottom of the pot.
- With a shovel or knife, trim the bottom 2" off the root ball for plants in plastic containers.
- Rotate the plant to the proper position. Never lift or move plants by the tops.
- Place the root ball in the hole.
- Adjust the plant height so the root crown is slightly higher than the ground.
- Notice where the base of the trunk flares out from the tree. This is called the root flare. This root flare should show when the tree is planted. Add soil under the ball so the root flare is exposed if necessary.
- Place fertilizer packets into the bottom of the hole (if purchased). *Use Our Recommended Fertilizer.
- Backfill the hole with soil, ensuring the top of the root ball is visible and slightly higher than the soil around it.
- Firm the soil around the plant. Water well to settle soil around the root ball.
Water frequently when newly planted. - Mulch plants with well-rotted organic matter after planting.
- Check out our Planting & Handling Guide for additional planting tips and illustrations.
Pruning - After Planting
- Containers: Although it’s not essential after planting, light pruning can help shape a Smooth hydrangea shrub. Doing so removes any broken branches from shipping or thins out a heavily branched plant to assist in the transplanting process and the appearance of your new planting.
Pruning - Through-out the Season
- Hydrangeas can be pruned in March and April.
- With hydrangeas, various types come with different pruning practices.
- Hydrangea macrophylla - Cut off spent flowers in spring and remove crowding shoots.
- Hydrangea paniculata - Prune stems to within two buds of the base in late March.
- Hydrangea petiolaris - Cut out unwanted shoots when flowers fade.
- Hydrangea villosa - Remove a third of older stems in spring.
Watering - After Planting
- Plants typically take approximately 6 weeks to establish new roots in your soil. During this period, water plants as often as every 2-4 days at the start and at least a minimum of once per week.
- Beyond the six-week establishment period, water once per week unless rain occurs.
- Remember to check soil moisture by sticking your finger into the soil around 3”.
Watering - Throughout the Season
- After the first season, plants should only be watered during extended periods without rain.
- How do you know if your plants need water? The easiest way to tell is to touch the soil around the roots. If it is moist, there is no need to water. If it’s dry, give it a good soak with the hose end (no nozzle), watering the soil only, not the leaves.
- Same as after planting, stick your finger into the soil around 3” to check soil moisture.

Do Incrediball® smooth hydrangea blooms stay as white flowers?
The blooms of a smooth hydrangea start out with its signature white flowers and gradually fade to a lush, jade green shade.
The change in color change is the result of fewer daylight hours as the summer progresses. Since the plant receives less energy from sunlight, the flowers adjust their ability to retain the white color.
