The Pocahontas lilac (Syringa x hyacinthiflora ‘Pocahontas’) produces a profusion of fragrant deep violet flowers on a large, deciduous shrub. The blooms make excellent cut flowers for bouquets. It blooms sooner than other lilac varieties and for a longer period of time, from spring through fall. This lilac can grow more than 10x10 feet , so make sure you have sufficient space in your yard before you plant one of these lovely ornamental plants.
Caring For a Pocahontas Lilac
Test your soil because lilacs need an alkaline environment with a pH of 6.0 to 7.0. If your soil tests on the acidic side, correct it by adding limestone or hydrated lime. (See Tips.)
Dig compost into the soil, and then plant your lilac in an area that will give it sufficient room to grow to its mature size of 10x10 feet or larger.
Water your lilac regularly during its first summer—twice each week is recommended for most climate zones. Water your lilac less after it is established, but water it more often before it blooms in spring.
Spread 2 to 4 inches of organic mulch around the base of your lilac to keep the soil moist and keep weeds away.
Fertilize with a low-nitrogen fertilizer in spring before new growth begins to promote blooming. After blooming is finished, fertilize with a balanced fertilizer.
Watch for signs of powdery mildew, and spray with a fungicide or natural spray of milk and water (1/2 cup milk to one gallon of water) when you first see signs of a white or grey sooty coating on the leaves. If the mildew spreads, cut off affected branches and foliage.
Control mice and moles, which like to chew on the bark at the base of this plant, by pulling back the compost around your lilac to deprive these creatures of a suitable habitat and cover.
Control insects such as aphids and borers, which are rare, with an insecticidal soap spray.
Prune your lilac back to old wood after flowering is complete.
