Don’t expect results right away from fragrant old-fashioned lilacs (Syringa), though they do make a charming natural hedge. Lilacs first develop slowly and might take up to five to seven years to fully fill out and bloom. They just require light pruning, and they look their best when left to develop naturally. Privet or boxwood are preferable options for a more formal, trimmed appearance. Lilac hedges are at their best in the spring when they blossom, but they also have lovely green leaves all summer long.
Lilacs need plenty of water the first year after planting until their roots take hold. Lilacs are moderately drought tolerant once they are established. Lilacs should be fertilized with a balanced 10-10-10 fertilizer in the spring of the second year and every spring after that.
Insect pests and disease must be treated on lilacs. Use dormant oil to treat leaf hoppers, aphids, and scale. Use a fungicide to treat powdery mildew, a typical but seldom dangerous lilac disease.
Can you use lilacs as a hedge?
Lilacs are frequently used to make lilac hedges and have a very great growth potential. A hedge will add lovely spring flowers while enhancing privacy. These lovely-smelling flowers draw bees and butterflies.
We focused on building a vegetable garden and a chicken coop when we relocated to a new homestead in 2016, but we also needed some solitude, so we planted a lilac hedge.
How long does it take lilac bushes to grow?
A lilac plant was given to me around seven years ago, and I planted it in our backyard. Each day, it receives several hours of direct sunlight. The leaves have always been a wholesome, mold-free green. It presently stands at about 7 feet. Every year, I eagerly anticipated the blossoms. The first blooms, consisting of two or three clusters of florets, appeared in the spring of 2011. There is only one this spring (now)! Can I do anything to ensure that the plant blooms the next spring?
A: One of the great things that gardeners look forward to each spring is the aroma of lilacs. I don’t think there’s much of a purpose to offer your lilacs significant yard space if they don’t flower. But there are a number of explanations for why they don’t blossom.
- Lilacs prefer a slightly alkaline soil (pH 6-7), even hydration, and lots of sunlight for optimal growth (at least 6 hours). Therefore, you might only get a few or no flowers if your soil is very acidic, it’s dry in the summer when the buds are growing, or your plant doesn’t get enough sun.
- Age: Lilac plants require time to develop before they start to bloom. Therefore, a young plant might not be mature enough to bloom if you have one.
Most plants begin to blossom after three to four years, while others might take up to seven. The first few years’ blooms will be rare, but they should become more numerous over time. If the plant you purchased was in bloom when you got it, then this is definitely not your fault.
- Pruning: Old wood is where lilacs bloom. They develop their buds during the summer so that by late January, they are completely developed and prepared to bloom.
So, two to three weeks after they bloom, or should have blossomed, is the ideal time to prune. Later trimming will reduce or stop flowering the following year. The plant can be kept healthy and flowering with yearly pruning. Remove any broken or dead branches first, then any old, woody ones, any that cross or rub, and then shape. Remove no more than one-third of the plant per year; nevertheless, if the plant is pruned on a three-year schedule, it will regenerate completely in just three brief springs.
- Overfeeding: Sometimes we solve one issue by causing another. Lilac typically doesn’t require further fertilizing. You will get a large, luxuriant plant but few, if any, blossoms if you feed your lilacs, especially if you use nitrogen-rich fertilizer.
Instead of flowers, nitrogen, the first number in a fertilizer indication, 10-5-5, encourages the growth of leaves.
- Transplant shock: Lilacs require some time to adapt. Even if a plant had blossoms when you got it, it is common for plants to take two or even three years to establish themselves and begin to bloom.
If none of the aforementioned scenarios apply to your lilac, you might want to offer the plant some stress, which is something we frequently do to wisteria that doesn’t blossom. A foot or so away from the lilac bush’s base, drive a sharp shovel’s blade into the ground. Cut the plant down, severing the roots on both sides.
I have two inquiries about tulips and daffodils. (1) What should I do with them after they’ve finished blooming? Do you want to base-cut them or deadhead them? (2) Where should I plant new flowers to replace them: immediately next to the bulbs? Do we remove all the green to make room for new blossoms in order to do this?
A: Although no one wants to hear it, the bare greens must be endured if you want to see the spring tulips and daffodils, even when they begin to look unsightly. The greens must stay, but you can tidy up the plants by trimming the flower stems to the ground. They shouldn’t be clipped, tied, or braided since they need to grow and store energy for the bloom the next year. The leaves can be removed from the bed and raked off once they have turned brown.
It is the same as putting perennials among the bulbs as far as that is concerned. Give them room to expand; take care not to disturb the bulbs when digging new planting holes; and, ideally, pick plants that will begin to grow just as the bulbs begin to fade. Daffodils and daylilies are a popular coupling that offers an excellent circumstance since the daylilies mature and cover the daffodil greens just as they begin to look pretty ragged.
Are lilacs suitable as a privacy hedge?
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!
Where shouldn’t lilac bushes be planted?
Avoid planting lilacs in areas that will receive more than a half-worth day’s of shade because they thrive in full sun. Make sure to give them room to expand when you plant them. To find out the mature plant’s height and spread, read the label on the plant.
Lilacs require sufficient drainage to thrive. The soil should have just enough moisture to support the root system while still allowing for free drainage after heavy rains.
Dig a hole that is about 8 inches in diameter and 12 inches deep to test the drainage before planting. Add water to the hole. Choose a different location if the water hasn’t drained after an hour.
The ideal lilac for a privacy hedge
The Old-Fashioned Lilac, a favorite of northern gardeners, will surely enchant your senses with its smell and lilac-purple flower panicles. This flowering shrub, sometimes known as the common lilac, has a spread of 6–12 feet and a height of 8–15 feet. Its floral panicles, which blossom in the middle to late spring, fill the air with fragrance and draw butterflies and hummingbirds. For fresh flower arrangements, you should cut a few flower panicles and bring them inside. The Old-Fashioned Jumbo Lilac is a stunning specimen plant, but it also looks great planted in small groups, as a flowering hedge or privacy screen, or in shrub borders. It requires adequate air circulation and well-drained soil despite being low maintenance. Deer frequently avoid it. grow anywhere from full sun to some shade. Zones 3-7.

How far should I plant lilacs 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.
A lilac shrub spreads, right?
Ballistichory, also known as ballistic dispersion, is a unique way that lilacs disperse their seeds that causes the seeds to fly out in a large arc around the plant. The architecture of the seed pod produces this explosive effect by building stress in the woody fibers as they dry, which causes them to break at a planned weak point and fold back to release the seeds. The lilac can now spread its own seeds without the aid of wind or animals thanks to this technique.
How can the growth of lilacs be sped up?
Lilac bushes grow fairly quickly, with some types growing more quickly than others. Any way you look at it, lilac bushes are a fast-growing variety of shrub.
By ensuring that your lilac shrub receives adequate sunlight and is placed in healthy soil, you can hasten its growth. It’s important to carefully and moderately water the lilac bush.
In the spring, fertilizer can be applied to the lilac shrub to help it grow. You should be able to observe your lilac shrub growing quickly each year if you heed our advice.
How can you promote the growth of lilacs?
Lilacs can be grown as trees, hedges, or freestanding bushes. Lilac plants can reach a height of 20 feet and effectively shade your yard. Lilacs have deep roots and thrive best when planted in elevated areas, on hillsides, or on flat, well-drained land. While there isn’t a magic trick to make lilacs grow more quickly, good management practices and an emphasis on fertilizing, mulching, and pruning will provide the plant with all it needs to grow quickly.
Plant quick-growing lilac cultivars. Late-blooming hybrids with fast growth rates, like “Agnes Smith” and “Miss Canada,” can reach heights of 25 feet or more. They flower later than other varieties of lilac. Miss Canada’s flowers are rose-pink, while Agnes Smith’s are white. The purple-flowered Syringa chinensis likewise has rapid growth and frequent blooming.

To prevent weeds from robbing lilac plants of their nutrition, mulch the area around the bushes. The roots’ temperature will be stabilized and the soil’s moisture content retained by a 2 to 3 inch coating of pine bark.
Plants should be pruned to promote blooming and expansion. Every year, soon after the plant has finished blooming, prune it to increase vigor. Once you have a cluster of seven to ten stems of various ages, remove any weak branches.
To allow sunlight to reach the lilac’s interior, thin down the top growth. The plant will develop new buds and expand more quickly. Eliminate weaker stems as well as those that are rubbing or crossing over one another. To improve the appearance of the bush, remove dead blossoms.
- To prevent weeds from robbing lilac plants of their nutrition, mulch the area around the bushes.
In the early spring or in the middle of October, boost growth with fertilizer. Per 25 square feet, apply 1/2 pound of 5-10-10 fertilizer. Apply the fertilizer all around the lilac’s base and then water it in.
