Antique-variety hydrangeas are beautiful flowers with large blooms. They are popular among brides, in particular, because they make a stunning arrangement when paired with roses. Antique hydrangeas have uniquely colored blooms, with no two blooms alike. They are most typically grown in pink/green varieties and blue/green varieties but can also be found in shades of bronze and lavender. The flowers bloom between mid-July and September.
Choose a planting location that has bright morning sunlight and afternoon shade. If you live in a cold climate, make sure it's a spot that provides shelter from the coldest weather in late fall and winter.
Add compost or organic mulch to the soil to make it as nutrient-rich as possible. This will also help retain moisture.
Test the soil to make sure the pH is suitable for antique hydrangeas. The ideal soil pH is between 6.0 and 7.0. A pH between 5.5 and 6.5 will encourage the blooms to take on a blue hue. A pH of 7.0 and higher will make the blooms closer to pink in color. Add hydrated lime to make the soil more alkaline and peat moss to make the soil more acidic. Fertilizer used on azaleas will also boost acidity.
Give antique hydrangeas 1 inch of water per week to moisten the soil. Lay down mulch around the base of the plants to retain moisture and protect the roots. Overly wet soil is not conducive to the plant because it loses aeration and compacts too much, resulting in damage.
Snip off old wood shortly after the flowers bloom to promote more extensive growth. Cut 1/4 to 1/3 of the old wood to the ground. If the plant blooms on new wood, make the cuts in late winter to early spring, before blooming, to encourage growth.
