Hydrangea Care

By August 10, 2018 November 27th, 2018 Gardening Blog

Hydrangeas like moist, rich soil, but can not live in standing water. They are big drinkers. On hot days, the fleshy leaves and stems call for lots of water. Make sure they get it! The best place to grow hydrangeas is where they get morning sun and afternoon shade. This will keep the heat stress to a minimum and ensure the best blooms.

Hydrangeas are acid-loving plants. Feed hydrangeas in spring or fall with Holly Tone. Mophead hydrangeas have large lush blooms that change color depending on the soil ph. If you like blue flowers, use soil acidifier; if you prefer pink use garden lime.

Pruning is required to keep your hydrangeas performing to the best of their ability. All hydrangeas can be pruned for cut flowers, and they like to be pruned during bloom time to promote healthy growth. Outside of bloom time, seasonal pruning will ensure a longer life span and beautiful plant architecture. The process for seasonal pruning depends on the variety.

Hydrangea macrophylla (mophead) – Nikko Blue, Forever Pink, and other mophead hydrangeas bloom off last year’s wood (old wood). Pruning should be done only when necessary to improve shape. When new growth begins in spring, prune away dead branches, fertilize with Holly Tone, and enjoy the beautiful blooms to come.

Hydrangea paniculata (panicle hydrangea) – Pee Gee, Limelight, and other panicle hydrangea varieties bloom on new wood. This means old wood can be pruned off late fall or very early spring. Prune them aggressively so that new growth will be clean and compact and the plant will be lush with blooms.

Hydrangea quercifolia (Oakleaf hydrangea) – Snow Queen, Queen of Hearts and other oakleaf hydrangeas bloom from old wood and look best left untrimmed. If you must, prune late winter and remove the entire stem. Do not prune tips in the spring time; this stunts growth and prevents future flowering.

Hydrangea anomala (climbing hydrangea) – This gorgeous, slow growing variety has woody vines that cling to structures with air roots. Blooms grow off old wood, so prune in late fall or winter to control shape and promote spring growth. Blooms are a wide, lacecap type of flower.

Hydrangea arborescens (Smooth hydrangea) – Annabelle, White Dome and other smooth hydrangea varieties bloom on new wood. Severely prune in late fall or winter and enjoy the flush of new growth and blooms in the spring and summer.

As always, please feel free to call or, even better, come by the shop with your questions, comments, or just to visit! I’ll see you soon.
