When the lilacs begin to blossom, it is a solid indicator that spring has arrived for good. While many people only have a limited knowledge of common lilac (also known as French lilac) shrubs that can reach a height of 15 feet or more, there are now a lot more options available than there were fifty years ago. Some varieties that rebloom enhance the garden’s appeal the entire growing season.
How to Choose Lilacs
The common lilac is what you will most likely find when you go plant shopping. This traditional plant comes in a variety of cultivars and variations, each of which yields fragrant spring flowers in pink, purple, white, or even combinations of those hues. Common lilacs are typically the most fragrant variety of lilac and can grow to be rangy and large.
Rebloomers have arrived in the garden center thanks to recent introductions of hybrids between the common lilac and other shrub-type lilacs. Some of these more recent types are a little less fragrant, but they also tend to be smaller, bloom more frequently throughout the growing season, and have fewer powdery mildew issues.
The tree lilac is another common variety of lilac. It can grow to a height of around 20 feet and blooms with cream-colored flowers in the middle of the summer. Though it doesn’t require much trimming, keep in mind that the tree lilac is a tree, not a shrub.
Where to Plant Lilacs
Lilacs should be planted in full light (at least 6 to 8 hours per day), as too much shadow will prevent them from blooming. Lilacs also prefer moist, well-drained soil that is slightly alkaline.
When to Plant Lilacs
Before the ground freezes in the late fall is the ideal time to plant lilacs. After the earth thaws in the early spring, that is the next ideal period to plant. Lilacs will likely need to be planted as soon as you can locate them at the garden center, which is great; if you choose to do so during a warmer season, they might require additional watering.
How to Prepare the Soil for Planting Lilacs
A soil test should be performed prior to planting since lilacs thrive in slightly alkaline (6.5 to 7.0 pH), moist, well-drained soil that is high in organic matter. Lime must be added to raise the pH if it is below 5.5. It’s time to get the soil ready when you’ve obtained the ideal pH. Improve individual planting holes by mixing Miracle-Gro Garden Soil for Trees & Shrubs in a 50:50 ratio with the natural soil to give lilacs a nutrient-rich start. Iron and phosphorus are also present in this garden soil to promote root development and ward off leaf fading.
What kind of area does a lilac shrub require?
Lilacs require a lot of space to grow, so that is the first planting rule. They will want a spot that is at least seven to eight feet broad for a hedge and 10 feet wide for a shrub.
Additionally, they require at least six hours of sun each day in order to bloom beautifully. Create an alkaline, well-drained soil. When planting, add a small amount of lime, and then apply it twice a year to keep the shrubs healthy.
Dig a hole for the plant about as deep as the pot or perhaps a little deeper so you can fill the hole with compost. To prepare the lilac roots for spreading out in their new home, remove it from the pot and score the roots. Backfill the hole after placing it in position. Add a little additional compost to the soil’s top layer for an extra boost of nutrients. Thoroughly water. The majority of lilacs are drought-resistant, so once the bush is established, you can let nature handle the watering.
How quickly will a lilac bush expand?
The lilac is a multi-stemmed, deciduous shrub with an erratic, rounded shape. When young, it grows quickly, but as it ages, its growth slows to roughly one foot every year. The stems’ sturdy wood has a dark gray to gray-brown color. The leaves are light green underneath and dark green to blue-green above. The clusters of four petal blooms, which come in lilac, light purple, or lavender hues, bloom in April or May. They have a strong fragrance. Although the lilac thrives best in sunny locations, it cannot stand hot, muggy weather. It requires moist, well-drained soil that is neutral or just a little bit alkaline in pH. Peat or leaf mold can be added to the soil as a supplement. As soon as they start to fade, old flowers should be removed. Lilacs should be pruned as soon as they finish blooming. Pruning the shrub is preferred since it will highlight the medium-aged wood, which will still contribute to the plant’s good size and produce nice blooms. Remove a third of the earliest stems at ground level each year to accomplish this. Any remedial trimming, like removing competing branches or sucker growth, can be done concurrently. Pruning older lilacs as small, multiple-branched trees will highlight a few massive, old trunks while removing sucker growth and making them a focal point of the landscape. The shrub can also be pruned into a tree with a single stem. Lilacs that are overgrown can be pruned to a few inches above the surface. They will bloom once more in three to four years, Depending on the mature height, space your plants 3–4 feet apart if you want a hedge.
Lilac bushes—can they stay small?
Who doesn’t like a beautiful lilac bush? A lovely garden accent is created by the subtle lavender tones and the powerful enticing aroma. Lilacs unfortunately have a propensity to grow enormous and disorderly, but the new varieties of dwarf lilac have compact proportions while still putting on the town’s best floral display. The dwarf lilac variants are just 4 to 5 feet (1-1.5 m) tall, which makes them ideal for small gardens or even containers. Regular lilacs can reach heights of 6 to 15 feet (2-4.5 m).
Are lilacs an excellent privacy plant?
We purchased several lilac bushes at a nearby nursery a few weeks ago with the intention of creating a lilac hedge at our Farmhouse. The old-fashioned, unassuming feel of the lilac blooms I’ve used in my arrangements is ideal for our century-old farmhouse. Lilacs provide excellent wind or privacy barriers when planted in a row. Today, we’ll show you how we built the lilac hedge that runs beside our garden and provide a tip for working with landscape fabric. Let’s start now…
We get our “renowned Ellensburg breeze from the west side of our garden.” Here, the wind blows for a good portion of the remainder of the year in addition to the Spring. In order to provide a beautiful break, we chose to put a lilac hedge along the west fence line. Once it has grown in for a few years, it should do so. Additionally, it will enhance the garden entry with some lush greenery and, of course, a ton of gorgeous, fragrant blossoms in the spring. Because they are drought-tolerant, low-maintenance, pollinator-friendly, and deer-resistant, lilacs are a favorite of mine.
James MacFarlane and Minuet lilac varieties were interspersed in this hedge. Here’s some information on each:

We chose these types because of their size—we wanted them to be tall enough to block the wind without overshadowing the garden. Additionally, we chose them since the nursery had them in stock. Even if sticking with just one variety would result in a very attractive hedge, blending the varieties should extend the blooming season and offer some extra color.
Here is a video of the planting procedure, along with our top landscape fabric working advice!
What distinguishes a lilac bush from a lilac tree?
Lilac bushes (also known as shrubs) are characterized by their numerous woody stems that emerge from the plant’s base. In contrast, the trunk of the majority of lilac trees is the only woody stem. However, your neighborhood garden center might also sell shrub lilacs that have been grafted onto a single stem to give them the appearance of miniature trees.
The choice between a lilac tree and a lilac bush is typically determined by the amount of space available. Lilac bushes come in a range of sizes and can be placed in more compact areas of a garden. A lilac tree requires space to reach heights of 20 feet and widths of 15 feet. Both require sunlight to bloom well.
How far should a lilac bush be planted from a fence?
There are a few factors you should take into account when deciding where to put your lilac shrub for best results. These are them:
-Plant your lilac containers or bare roots at least 5 feet apart from one another to provide each plant enough room to spread its roots and adequate airflow.
For the same reason as above, try to plant lilac bushes a few feet away from a wall or fence. This shrub spreads out widely as it matures. Just like other shrubs, they can expand over several feet, so make arrangements accordingly.
-Place your lilac shrub where it will receive at least 6 hours per day of FULL SUN. This refers to daytime direct sunshine that isn’t filtered by other trees or any form of shade. Your lilac needs several hours of direct sunlight each day even if you live in the South and may need to protect it from the sun during the summer.
-Try to pick a location that is a little higher above the rest of your yard. This will contribute to ensuring proper drainage, which lilacs require to thrive.
Is it possible to grow a lilac shrub adjacent to a home?
Lilac roots aren’t thought to be invasive, so planting lilacs close to a building’s foundation poses no risk as long as you give them adequate room. The average root spread for lilac shrubs is 1.5 times that of the shrub’s width. In most cases, keeping objects away from the foundation at least 12 feet (4 meters) will prevent foundation damage.
How long does a lilac bush live?
Lilacs are renowned for their longevity and hardiness.
Numerous lilac shrubs reach ages of greater than 100. They frequently outlive the residence of the gardener who planted them due to their extended lifespan. As a result, if you’re driving along a country road and come across a few what appear to be random lilac bushes, it was probably a farm or house a century ago.
Try growing lilacs in your garden if you haven’t already. They not only return every year, but they also put on a display for the senses with vibrant blossoms and enticing scents. Lilacs have a lot to offer, and learning about their history demonstrates just how unique these plants are.
What shrub for seclusion has the fastest rate of growth?
Evergreen arborvitae come in a variety of sizes, including the comparatively diminutive “North Pole,” and they all grow at different rates. As a result, not every arborvitae is appropriate for use in privacy hedges. The quickly growing “Green Giant,” which may grow to a height of 50 to 60 feet, is a wonderful option for substantial privacy hedges (with a spread of 12 to 20 feet). ‘Emerald Green’ arborvitae is a better choice if you want a bush that is more compact and don’t mind waiting a little longer. The latter rarely exceeds 12 to 14 feet tall and has a spread of no more than 3 to 4 feet. If you look closely, the foliage of this plant has flat sprays and what appears to be scales on the needles.
Do lilacs make dogs sick?
Lilacs don’t have any poisonous or irritating substances that could harm people or animals. Even though chewing on lilac stems, leaves, and flowers has no health risks to dogs, it is still a good idea to prevent this from happening. A pet’s digestive tract may become disturbed if they consume too much roughage. Additionally, twigs and leaves might get caught in their throats. Additionally, dogs’ inability to digest large amounts of plant matter can result in nausea or diarrhea. The Persian lilac (Melia azedarach), which is not related to actual lilacs, is deadly to dogs, according to the ASPCA Animal Poison Control Center.
What tree for privacy has the fastest rate of growth?
Numerous plants are suitable possibilities. Actually, it’s best to vary things. In this manner, your screen won’t be affected if one plant contracts a pest or disease.
Yet another item! Fast-growing trees can quickly give you privacy, but they have certain drawbacks as well. Fast-growing trees and shrubs typically have weaker wood that is more vulnerable to breakage and pest and disease attack. In order to keep them under control and encourage the development of a sturdy structure, they also require more frequent trimming.
