Still, regular pruning encourages new growth that can produce a better display. The flower mops range from four to six inches in garden conditions, and up to eight inches when planted in containers.
Foliage is a medium-to-deep green, and has shown good mildew resistance. The plant grows three to five feet in width and height. It is partial to sun, enjoys a rich soil, and requires abundant water. Because of their size and dense foliage, hydrangeas are treasured as shrubs and border plants. These big leaf hydrangeas thrive in moist but well-drained soil, preferring morning sun. Avoid planting macrophylla hydrangea mophead and lacecap types in dry, with full sun exposed areas, or unprotected areas where extreme cold winds may damage young spring growth.
These types are sun-lovers. While they prefer the sun, these hydrangeas will do just fine in partial shade, too. Unlike their famous shade-loving cousins, the macrophylla, or mop head hydrangea, which bloom on old wood. Hydrangea quercifolia, also known as Oakleaf hydrangeas, such as Alice and Ruby Slipper , are sun-loving hydrangea that flower on old wood growth.
In the last few years, breeders have been developing many excellent varieties along with introducing new colors with bright whites, creams, lime green, and various shades of pink. Some of our most popular panicle hydrangeas are the Bobo, Quick Fire , and Limelight. Limelight , with its huge football-shaped flowers, has almost revolutionized landscaping across America. Opening into light green, the blooms age to a bouquet of pink, red, and burgundy persisting through frost. Breeders have recently introduced a sibling Little Limelight growing three to five feet tall and wide.
One of the first hydrangeas to bloom, the Quick Fire bloom emerges bright white and as blooms age; they change color to pink and finally red, giving the plant a multicolored effect in late summer and early fall.
Hydrangea failing to bloom is a common dilemma for many of the older varieties of macrophylla and oakleaf hydrangeas. An unseasonable hard freeze or an improper pruning is typically the cause. These hydrangea types bloom on old wood. Winters with extreme freezing temperatures can injure unprotected flower buds. It's a large shrub or small tree to 20 feet tall. It grows eight feet tall.

Tell us what you think Thanks for adding your feedback. Planting Hydrangeas As with most things in your garden, learning the basics of how to plant hydrangeas can save you time and money.
Best time to plant hydrangeas Fall is the best season to plant hydrangeas, followed by early spring. Where to plant hydrangeas Knowing where to plant hydrangea shrubs is an important first step. Best soil for hydrangeas Hydrangeas grow well in soil containing an abundance of organic material. How to plant hydrangeas To plant hydrangeas, simply dig the planting holes 2 feet wider than the root ball. How to propagate hydrangeas One hydrangea can turn into many through simple propagation techniques.
All you have to do is: Dig a small trench near your hydrangea plant. Bend a branch down to the trench so it touches the soil in the middle of the branch six to 12 inches of branch should extend past the trench. Make scratches in the bark where the branch touches the trench soil. Fill in the trench and place a paver, brick or stone on top.
With time, the branch will form its own root system and may be transplanted to a new location. Water at a rate of 1 inch per week throughout the growing season. Deeply water 3 times a week to encourage root growth. Bigleaf and smooth hydrangeas require more water, but all varieties benefit from consistent moisture.
Use a soaker hose to water deeply and keep moisture off the flowers and leaves. Watering in the morning will help prevent hydrangeas from wilting during hot days.
Add mulch underneath your hydrangeas to help keep the soil moist and cool. An organic mulch breaks down over time, adding nutrients and improving soil texture.
Apply fertilizer based on your specific hydrangeas. Each variety has different needs and will benefit from different application timing. The best way to determine your fertility needs is by using a soil test. Bigleaf hydrangeas need several light fertilizer applications in March, May and June. Oakleaf and panicle hydrangeas do best with two applications in April and June.
Smooth hydrangea plants only need fertilization once, in late winter. Protect against pests and disease by choosing cultivars with resistant traits. Leaf spots, bight, wilt and powdery mildew can all appear on hydrangeas. Pests are not common on hydrangeas, but can appear when plants become stressed. Possible pests include aphids, leaf tiers and red spider mites. Properly caring for hydrangeas is your best defense.
