Cherry-Go-Round® Reblooming Hydrangea

Cherry-Go-Round® is hardy in zones 5 to 9 and performs best in part sun — ideally morning sun with shade through the hottest part of the afternoon. Like all bigleaf hydrangeas, it wants rich, consistently moist but well-draining soil, and its bloom color will trend bluer or more purple in acidic soil and pinker or redder in neutral-to-alkaline soil.

Planting

1. Choose a spot with morning sun and afternoon shade; too much hot, direct sun causes wilting and faded blooms.
2. Work the bed with compost or other organic matter so the soil holds moisture yet drains freely; soggy ground invites root rot.
3. Dig a hole as deep as the root ball and about twice as wide to loosen the surrounding soil.
4. Set the plant so the top of the root ball sits level with the surrounding grade, then backfill and firm gently.
5. Water in thoroughly and add 2 to 3 inches of mulch to conserve moisture, keeping the mulch pulled back from the stems.

Care & maintenance

• Water. Keep the soil evenly moist, especially the first season and during heat; bigleaf hydrangeas wilt quickly when dry. Deep, regular watering beats frequent shallow sprinkles.
• Feed. Apply a balanced or bloom-oriented shrub fertilizer in early spring as growth begins; a second light feeding in early summer supports rebloom. Avoid heavy late-season nitrogen, which pushes leaves at the expense of flowers.
• Light. Part sun is ideal — enough morning light for strong bloom, with afternoon protection to prevent scorch and wilting.
• Prune. This is a reblooming bigleaf hydrangea that flowers on old and new wood. Prune only lightly — remove spent blooms and any dead or weak stems right after the first flush in summer. Avoid hard pruning in late winter or early spring, which removes the old-wood flower buds and reduces the early show.
• Mulch & winter care. Maintain a mulch layer year-round to moderate soil temperature and moisture. In the colder end of its range (zone 5), a deeper layer of mulch or leaves over the crown helps protect old-wood buds through winter.
• Pests & disease. Generally trouble-free. Watch for aphids and spider mites in dry spells, and for leaf spot or powdery mildew where air flow is poor — space plants well and avoid wetting the foliage late in the day.
• Bloom tips. Deadhead faded mopheads to keep the plant tidy and encourage new flushes. To steer bloom color, lower soil pH with an acidifier for bluer, more purple tones, or raise it with garden lime for pinker, redder tones.

When does it bloom and how long?

As a reblooming bigleaf hydrangea, Cherry-Go-Round® produces its first flush in late spring to early summer and then keeps generating fresh mopheads on new growth through summer and into fall. Expect color across a long window rather than a single short burst.

Why isn't my hydrangea blooming?

The usual culprits are pruning at the wrong time, too much shade, or a late frost. Because this variety blooms on both old and new wood it is forgiving, but cutting it back hard in late winter still removes the old-wood buds. Too little light or a heavy dose of high-nitrogen fertilizer can also push leafy growth instead of flowers, and a hard spring frost can damage early buds.

How do I get blue versus pink or red blooms?

Bigleaf hydrangeas respond to soil pH. Acidic soil produces bluer, more purple tones, while neutral-to-alkaline soil brings out the pinks and reds. Lower pH with a soil acidifier or aluminum sulfate, or raise it with garden lime, and give changes a few weeks to show.

When and how should I prune it?

Prune lightly and only after the first summer flush: deadhead spent blooms and remove any dead or damaged stems. Skip hard late-winter pruning so you don't sacrifice the old-wood buds that drive the early-season display.

Does it grow in sun or shade?

Part sun is the sweet spot. Morning sun with afternoon shade gives strong blooms while protecting the plant from heat stress and wilting. Deep shade reduces flowering, and full afternoon sun in hot climates can scorch the leaves and blooms.

Can I grow it in a container or use it as a low hedge?

Yes to both. Its naturally compact 2-to-3-foot habit makes it well suited to large patio pots and to low, informal hedging or repeated front-of-border plantings. In containers, use a quality potting mix, water consistently, and in zone 5 give the pot extra winter protection since roots are more exposed to cold.
