Like most oakleaf hydrangeas, Snowcicle requires full sun to partial shade. These plants are happiest in locations that feature a bit of shade in the afternoon, but, with adequate watering and mulching to retain moisture, afternoon shade is not required. Just make sure that your Snowcicle receives at least four to six hours of sun each day.

Once planted, water the snowcicle hydrangea one or two times every week, keeping soil moist. For best results, use a soaker hose to give the roots a deep watering. Or, use a hose or watering can to water deeply twice per week, watering at the base of the plant. Avoid watering at night, and water at the base, not the leaves. Avoid letting roots dry out.
Pruning hydrangeas is an annual task that can keep your plants healthy and happy. However, these plants require much more minimal pruning than other types of hydrangeas. Oakleaf hydrangeas bloom on old wood, meaning that they bloom on last year's growth. Flower buds for the next season develop after blooming in spring. So, you won't want to cut your canes back too far, or you may reduce next year's blooms.
The best time to prune an oakleaf hydrangea, including Snowcicle, is immediately after flowering. This timing prevents interruption of the blooming process for next year. Look for crossed or damaged branches, and remove those pieces. You can trim back your plants to maintain size or shape, but never prune back more than one third of each cane.

Oakleaf hydrangeas don't require too much over-winter care. Prune after blooming in spring, but leave plenty of cane in place, since these plants bloom on old wood. You can also leave some blooms on the plant to add winter interest, if you like.
If you're growing in a zone in which your plant is hardy-for Snowcicle Oakleaf Hydrangea that's Zone 5-9-you can mulch around your hydrangea, and then allow it to go dormant for the winter. Resume watering when the plant greens in the springtime.
