Tips for Care

This beautiful shrub is exceptionally cold hardy and very easy to care for. While it can be grown in either sun or partial shade, please know that it will flower best in a sunny spot.

In the very coldest Zone 3 gardens, it’s a good idea to give it a protected spot from the very worst of the bitter winter winds. Try planting on the sunny side of taller evergreen trees or on the south side of your home or outbuilding.

Give it well-drained soil or improve your drainage with a technique called mounding up. Add additional soil to 18 – 24 and plant directly in that mound. You can also create lovely raised beds to bring visual structure to your planting designs.

Give your plants a moderate amount of water on a regular basis. This is especially important in spring. Don’t let the soil dry out during the flower development stage to encourage big, huge flower heads. Give your Hydrangea paniculata ‘Phantom’ a nice, thick layer of mulch over its root system to keep it nice, moist, and cool.

Prune back hard in early spring, and you’ll enjoy fresh new flowering growth later in the season. This is a simple yearly task that should be done before the plant has started to leaf out.

Don’t prune once you see new growth, or you’ll risk cutting off those breathtaking blooms for the year!

Before your shrubs start growing in early spring, trim the overall size back by about a third. Keep a rounded shape for the best results and make pruning cuts at a 45-degree angle just above a fat, swollen leaf bud. In this manner, you can easily maintain the of the overall size from 5 to 10 feet tall.

Once your Phantom is mature, conduct a regular schedule of renewal pruning cuts every few years in early spring. Remove the oldest, thickest stems all the way down to the ground. You’ll leave the younger, thinner stems and shorten them up by a third. Your shrub will love this freshening up and respond beautifully.
