How to Care for a Lilac Bush in Your Home Garden

The common lilac (or the *Syringa vulgaris*) is a deciduous bush that flowers with colorful, fragrant blooms typically at the end of May. Before flowering, lilac bushes have dense foliage. Lilac bushes are occasionally mistaken for trees because they get so tall, but they are large shrubs or bushes. The lilac bush has about 10 canes from its central stem, giving it a dense structure. Common lilacs bloom in several flower colors at the end of spring: blue, pink, light and dark purple, or white. Lilac shrubs thrive best in northeastern climates, but they are hardy shrubs and can generally grow in a lot of different places with the right conditions and care. The lilac bush’s hardiness makes it a great addition to any size garden. There are several varieties of lilac bush types that bloom with bright spring colors, but the one constant is their beautiful scent. 1. __Common lilac shrub (*Syringa vulgaris*)__: The common lilac shrub has blooms in many colors, from light purple to red. Wedgewood blue, a lavender-blue shade, is the color you likely see most; the common Charles Joly lilac blooms for up to four weeks in the summer in a deep magenta color. These lilac shrubs can grow to 12 feet high and at least 10 feet wide. 2. __Dwarf Korean lilac (*Syringa palibin*)__: This lilac bush is smaller in size, only reaching 4 to 6 feet in height, but its light pink flowers still have the classic sweet smell of lilac. Dwarf Korean lilacs are ideal for small gardens. 3. __Persian lilac (*S. persica*)__: If you live in the warmer climates of the U.S. South, this is the perfect lilac for your garden. It can grow up to 8 feet tall and 10 feet wide, with large lavender blossoms. 4. __Littleleaf lilac (*S. microphylla*)__: Flowering late in the summer, this lilac bush varietal is perfect for extending the blooming season in your garden. This reddish-pink lilac requires more watering than other varieties. 5. __Early flowering lilac (*Syringa hyacinthiflora*)__: These red-pink lilacs have an early bloom time, about a week before the common lilac. 6. __Tinkerbelle (*S. bailbelle*)__: Another of the dwarf varieties, this lilac is ideal for small gardens. They also bloom late in the lilac bloom season, around early summer. Lilac bush care and maintenance vary on the space you’re able to give them and requires paying attention to pruning. Still, lilacs are low-maintenance compared to many other shrubs. Make sure to plant your lilac bush in a part of the garden with full sun. You’ll also want to pick a spot that’s easy to access for pruning; lilacs can get dense when they bloom, and pruning regularly will help air circulation through the lilac bush. Trim the leaves, and then trim the inner canes closest to the central stem. When you prune the lilac bush just after flowering, you create space for the new shoots to flower next season. Lilac care after blooming is just as important as planting lilacs well. Lilac flowers also do not respond well to over-watering, so picking an area and a slightly alkaline soil type that allows good drainage is essential. Water the lilacs to the soil level, and they do not need watering more than once a week during the summer if you live in a rainy area. If you’re wondering when to plant a lilac bush, it’s best to plan ahead. The lilac plant root system takes some time to develop, so plant them in the fall before the ground freezes for a long growing season. You can also plant a lilac bush in early spring or late winter, right after the ground thaws. However, you might have to wait until the next year for the fullest and best lilac bloom. To propagate a lilac bush, take cuttings from the lilac bush during the high blooming season (late spring or early summer). In the morning, collect several 4- to 6-inch cuttings, and remove the bottom leaves. Then, take a pot filled with potting soil, sand, and perlite. After dampening the mixture, create a small hole with your finger in the pot. Put the cutting in the hole and pat the soil mixture around it so it stands up straight. Finally, place the pot in a warm location. No sunlight is needed. Lilac bushes planted in direct sunlight with rich soil types will also thrive. To help them grow stronger, you can use fertilizer with the soil around the shrub. A little bit of mulch will also help, but too much fertilizer or mulch will inhibit new growth on the lilac bush. While lilac bushes are relatively easy to grow, there are still some pests and diseases to watch out for, including: 1. __Powdery mildew__: Powdery mildew can occur when a lilac bush isn’t pruned enough. Summertime, after flowering, is the best time to prune to ensure that your lilac doesn’t have too many heavy canes during the next flowering season. 2. __Lilac bacterial blight__: This is easily recognizable on lilac bush leaves. Dark black streaks happen when bacteria causes flowers to turn brown and flower buds to turn black. It’s hard to deal with, but when you’re buying a lilac bush, you can ask for a blight-resistant variety. When caring for a lilac bush affected with lilac blight, prune off all the infected parts, and avoid over-watering. 3. __Lilac borers__: Lilac borers are moths that like to infest lilac bushes. Keep an eye out for eggs when you’re pruning your lilac bush, or look for a safe insecticide to combat borers and not compromise your lilac bush care.
