Grow Lilacs: A Fragrant, Rewarding Garden Addition
(From the “How to Grow Lilacs” Series by 1st Choice Fertilizer)
Growing lilacs brings more than just vibrant spring blooms—it connects you with nature, enhances your landscape with timeless beauty, and fills your garden with one of the most beloved floral scents. Whether you’re starting with a single shrub or planning a fragrant hedge, lilacs are a rewarding addition to any yard.
Getting Started with Lilacs
Success with lilacs begins with choosing the right location. These hardy shrubs thrive in full sun—aim for at least six hours of direct sunlight per day to ensure strong blooms. Good air circulation is also key to preventing disease and encouraging healthy growth.
Lilacs prefer well-drained, slightly alkaline soil. Before planting, test your soil’s pH and drainage. If needed, amend heavy clay with compost and organic matter, or add garden lime to raise the pH slightly. Once your site is ready, you can choose between bare-root or container-grown lilacs—both are excellent options for beginners.
Caring for Your Lilacs
After planting, the first year is about establishing strong roots. Water deeply and consistently, especially during dry periods. Lilacs don’t like “wet feet,” so avoid soggy soil. Once established, they’re quite drought-tolerant.
Pruning is essential for keeping lilacs healthy and flowering well. The best time to prune is right after blooming in late spring—this allows next year’s flower buds to form. Remove spent blooms, thin out crowded branches, and cut back old, woody stems every few years to rejuvenate the plant.
Fertilizing lilacs isn’t always necessary, but if growth is slow or flowering is sparse, a balanced fertilizer—like 1st Choice Bloom Booster 5-10-5—can help. Apply in early spring before new growth emerges. Avoid over-fertilizing, especially with high-nitrogen blends, as this can promote leaves over blooms.
Watch for common lilac issues like powdery mildew, lilac borers, or scale insects. With good air flow, proper pruning, and the occasional organic spray (like neem oil), most problems can be managed with minimal effort.

Grow Lilacs
(From the “How to Grow Lilacs” Series by 1st Choice Fertilizer)
There’s something special about growing lilacs—whether it’s enjoying their fragrant spring blooms, carrying on a gardening tradition, or simply finding joy in nurturing a shrub that rewards your care year after year.
Where to Begin: Planting with Purpose
Before you grab a shovel, it’s worth spending a little time planning. Choosing the right location can make all the difference in how well your lilacs grow and how beautifully they bloom. Key things to consider include sunlight exposure, soil drainage, spacing, and airflow—lilacs need full sun and good air circulation to thrive and resist disease.
You’ll also want to understand your soil. Lilacs do best in well-drained, slightly alkaline soil. Whether your yard has clay, loam, or sandy soil, we walk you through how to amend and prepare it for healthy root development. Starting with bare-root or container-grown lilacs? Both are beginner-friendly with just a few simple steps to follow.
Ongoing Care: Keeping Your Lilacs Healthy
Once planted, lilacs benefit from steady, thoughtful care. That starts with watering—especially during the first growing season. Lilacs don’t like soggy roots, but they do need consistent moisture early on to establish strong growth.
Pruning is one of the most important tasks in lilac care. To encourage vibrant blooms and a well-shaped shrub, prune immediately after flowering in late spring. Remove spent blooms, thin overcrowded stems, and rejuvenate older growth every few years for continued performance.
Fertilizing helps support healthy foliage and strong flower production. We recommend applying a low-nitrogen formula—like our 1st Choice Bloom Booster 5-10-5—in early spring. Avoid high-nitrogen fertilizers, which promote leafy growth at the expense of flowers.
Lilacs are fairly low-maintenance, but they can encounter pests or fungal issues like powdery mildew or lilac borers. Our care guides provide tips for prevention and organic treatment options like neem oil or horticultural sprays.

Acclimating Lilacs Before Planting
(From the “How to Grow Lilacs” Series by 1st Choice Fertilizer)
Before your lilacs ever take root in your garden, there’s one important step to help them start strong: acclimation—also known as hardening off. This gentle transition prepares your young lilac shrubs for life outside the controlled greenhouse environment they were likely raised in.
At 1st Choice Fertilizer, many of our container-grown lilacs arrive with tender new leaves and buds. While this growth is a good sign of plant health, it’s also more sensitive to outdoor conditions like wind, direct sunlight, or cool temperatures. That’s where acclimation makes a difference.
Why Acclimation Matters
New foliage on lilacs is especially vulnerable to stress from sudden environmental changes. Without proper acclimation, your shrubs may suffer from leaf scorch, wilting, or transplant shock—all of which can slow growth or affect future blooming.
Common environmental stressors include:
-
Cool temps below 45–50°F
-
Sudden frost or late spring cold snaps
-
Direct, intense sunlight
-
Strong, dry winds
These are especially common in early spring, but can happen anytime the weather swings. Acclimation helps ease your lilac into its new surroundings without stress.
Acclimating Bare-Root Lilacs
Bare-root lilacs are typically shipped dormant (no leaves), making them less prone to transplant shock. However, hydration and timing still matter.
Before planting:
-
Soak roots in a bucket of water for 1–2 hours (no longer than 24 hours).
-
Plant right away—ideally in early spring or late fall when conditions are cool and stable.
-
Avoid planting during hot, dry spells or just before a cold snap.
Acclimating Potted Lilacs
If your lilac arrives leafed out in a pot or bag, it was likely raised in a greenhouse or shaded nursery area. Sudden full exposure can damage tender growth. Here’s how to help it adjust:
-
Unpack and place the lilac outdoors in a partially shaded, sheltered location like a porch or patio for the first day or two.
-
Gradually increase sunlight exposure over 3–5 days, eventually moving it to a spot with full sun (6+ hours/day), which lilacs prefer.
-
Water on arrival, then allow the top inch of soil to dry slightly before watering again.
-
Watch for signs of stress like leaf curl, browning, or wilting. If noticed, move to filtered light and out of strong wind.
-
Avoid leaving it outdoors overnight if temperatures are near freezing. Bring indoors or into a garage if needed.
After 3–5 days of gradual exposure—assuming soil temps are above 50°F—your lilac is ready to plant. Overcast or cooler days are best for transplanting.
A Few Extra Tips
-
Adjust for your climate: If you’re in a warmer or colder region, extend or shorten the acclimation process as needed.
-
Indoor option: If weather conditions are too harsh, keep your lilac in a sunny indoor window temporarily.
-
Be patient: Some lilacs adjust in just a few days, while others may take up to a week.
Acclimating your lilacs properly sets them up for healthier growth and bigger blooms in the seasons ahead. It’s a simple but powerful part of planting with success—and just one step in your journey with 1st Choice Fertilizer and our “How to Grow Lilacs” guide.

Choosing the Right Location to Plant Lilacs
(From the “How to Grow Lilacs” Series by 1st Choice Fertilizer)
Success with lilacs starts well before you dig the first hole. Picking the right location ensures your lilacs will thrive, bloom beautifully, and bring you years of fragrant spring joy.
Here are five key things to think about before planting lilacs:
-
Sunlight and soil quality
-
Airflow and surroundings
-
Spacing
-
Drainage and root room
-
Room to expand in the future
1. Sunlight & Soil: Set the Stage for Flower Power
Lilacs are sun-loving plants. To produce those iconic, abundant blooms, they need at least 6 hours of direct sunlight daily—more is even better. Too much shade can lead to weak flowering or none at all.
Good soil drainage is just as important. Lilacs dislike “wet feet,” so avoid spots where water tends to pool after rain. They prefer loamy or slightly sandy soil that drains well but retains some moisture.
If your soil is clay-heavy or compacted, amend it with organic matter like compost, peat moss, or 1st Choice Coco-Fiber Growing Medium. For especially poor soils, consider building a raised bed at least 12″ deep.
2. Airflow & Surroundings: Keep Things Breezy
Lilacs thrive with good air circulation, which helps prevent powdery mildew and other common fungal problems. Avoid planting too close to buildings, fences, or dense evergreen hedges.
Check for:
-
Nearby trees or shrubs that may eventually cast shade
-
Wind tunnels between structures that could dry out young plants
-
Obstructions like AC units or window wells where growth may interfere over time
Imagine your lilac at full size—it may reach 6 to 10 feet tall and wide, depending on the variety.
3. Space Wisely: Let It Breathe
Lilacs are shrubs, but they need room to grow both above and below ground. Overcrowding reduces flowering and increases disease risk.
Here’s a general spacing guide:
-
Standard lilacs: 6–8 feet apart
-
Dwarf or compact varieties: 4–6 feet apart
-
Hedge planting (for a living fence): 3–4 feet apart
Make sure each plant has enough light and airflow on all sides, especially if planting multiples.
4. Drainage & Root Considerations
Lilacs have non-aggressive roots, but they still spread out over time. Avoid planting too close to septic tanks, water lines, or shallow foundations. Moist, rich areas will encourage root spread—but don’t plant where water stands for more than a day after rain.
Not sure how your soil drains? Dig a hole 12 inches deep, fill it with water, and watch. If it drains in under 2–3 hours, that’s a good sign.
5. Plan Ahead: Leave Room to Grow
Once you see how beautiful and low-maintenance lilacs can be, you may want more! Whether you plan to add another lilac, companion shrubs, or even other pollinator-friendly plants, leave room for expansion now so you won’t feel boxed in later.
This foresight will make it easier to design a cohesive, healthy landscape that brings beauty to your yard for years to come.
Ready to Plant? You’re Almost There.
Choosing the right location is one of the best things you can do to ensure your lilacs grow strong and bloom reliably. With a little planning—and help from 1st Choice Fertilizer—you’re well on your way to a lush, fragrant garden.
How to Plant Lilacs the Right Way
(From the “How to Grow Lilacs” Series by 1st Choice Fertilizer)
Planting lilacs is the first step in growing a stunning, fragrant garden that rewards you every spring. While lilacs are hardy and low-maintenance once established, giving them a strong start will help ensure vigorous growth, abundant blooms, and decades of beauty.
Getting Started: Prep Before You Plant
If your lilacs are bare-root (often shipped dormant), soak the roots in water for 1–2 hours before planting—but never more than 6 hours. This prevents dehydration during transplanting. Keep roots from freezing or drying out prior to planting.
If your lilacs arrive potted or bagged, water the container well, and keep them in a shaded, sheltered area until you’re ready to plant.
Step-by-Step Planting Guide for Lilacs
1. Dig Deep & Wide
Dig a hole twice as wide as the root ball and just as deep. This allows roots to spread easily and establishes a good anchor. Set aside the topsoil—it’s your best material for backfilling.
2. Enrich the Soil
Mix compost, rotted manure, or Coco-Fiber Growing Medium from 1st Choice Fertilizer into your topsoil. Lilacs prefer neutral to slightly alkaline soil (pH 6.5 to 7.5), so avoid overly acidic amendments like peat moss unless balanced.
3. Position the Lilac
Place the lilac upright in the hole. For bare-root plants, gently spread the roots. For container lilacs, loosen any circling roots to encourage outward growth. Begin backfilling with enriched topsoil, tamping lightly to remove air pockets.
4. Water Catchment (Optional)
If you’re planting on a slope, build a low berm around the base to help hold water near the roots. This helps during the first year while roots are still developing.
5. Mulch for Moisture & Weed Control
Spread 2–3 inches of mulch (such as bark chips, straw, or shredded leaves) around the base—but keep it a few inches away from the main stem. This keeps the soil moist, suppresses weeds, and protects against temperature swings.
After Planting: Care and Protection
-
Water deeply after planting—about a gallon per plant.
-
Continue to water once a week during the first season if rainfall is less than 1 inch.
-
Avoid fertilizing in fall. For spring plantings, apply a slow-release or lilac-safe fertilizer like 1st Choice Flowering Shrub Blend about 4–6 weeks after planting.
How to Plant Potted Lilacs
If your lilac comes in a container:
-
Remove it gently from the pot. If roots are circling, tease them apart carefully.
-
Keep the root ball intact while positioning it in the hole at the same soil level it was growing before.
-
Backfill and water thoroughly, as with bare-root plants.
-
Staking is rarely necessary, but if the plant is top-heavy or in a windy spot, a temporary stake can help.
⚠️ Do not plant the plastic pot in the ground—it will restrict root growth and cause long-term problems.
Final Tip: Remove Nursery Tags
Those little plastic tags wrapped around stems may seem harmless—but they can eventually girdle your lilac as it grows. Remove them after planting, or reattach loosely with soft twine and check regularly.
You’re On Your Way
With the right planting method and a little patience, your lilac will reward you with clouds of fragrant blooms and reliable beauty for decades. And with 1st Choice Fertilizer’s guidance and soil-boosting products, you’re set up for success from the start.
How to Prepare Soil for Planting Lilacs
(From the “How to Grow Lilacs” Series by 1st Choice Fertilizer)
Lilacs thrive in well-prepared soil. Before you even take your lilac out of its pot (or unwrap its bare roots), preparing the planting site is one of the most important steps for long-term success. Healthy soil supports strong roots, which in turn lead to vigorous growth and fragrant, plentiful blooms.
Whether you’re planting in spring or fall, getting your soil in top shape will set your lilacs up for decades of beauty.
Why Soil Preparation Matters for Lilacs
The right soil environment helps your lilac:
-
Establish quickly and develop a strong root system
-
Access nutrients efficiently
-
Drain well (avoiding root rot)
-
Resist disease and handle seasonal stress
We recommend testing your soil before planting. Lilacs do best in neutral to slightly alkaline soils (pH 6.5–7.5). A 1st Choice Digital Soil Meter can help with quick pH and moisture readings. For more detailed analysis, contact your local Cooperative Extension for a lab soil test.
Understanding Soil Types
Knowing your soil type helps determine how much amending you need to do:
Clay or Silt Soils
-
Heavy and dense; often compacts easily
-
May cause water pooling, especially in winter
-
Requires loosening and organic matter for airflow and drainage
Loam Soils
-
The ideal mix of sand, silt, and organic material
-
Drains well but retains moisture
-
Only minor adjustments needed—usually ready for lilacs!
Sandy Soils
-
Light and fast-draining, but low in nutrients
-
Lilacs planted here will need more frequent watering and soil amendments to retain nutrients and moisture
When to Prepare the Soil
Soil can be amended any time the ground is workable (not frozen or overly wet). For spring planting, prep in late fall or early spring. For fall planting, prep in late summer.
Early prep allows soil amendments to break down and blend with the native soil, improving conditions before planting.
What to Add to Your Soil
Lilacs love loose, well-drained soil that’s rich in organic matter. Here’s what to consider:
-
Compost – Boosts microbial life, adds nutrients, and improves texture
-
Well-aged manure – Increases nitrogen and structure (never use fresh manure)
-
Coir or shredded leaves – Helps lighten clay soil and add water-holding capacity
-
Garden Lime – Raises pH if your soil is too acidic (common in rainy or pine-heavy areas)
-
Wood ash – Another natural way to raise pH, but use sparingly
Avoid peat moss unless you need to lower pH, as lilacs do not like acidic soil.
How Organic Matter Improves Different Soils
-
Sandy Soil → Organic material slows down water loss and improves nutrient retention
-
Clay/Silt Soil → Organic matter breaks up compaction, improving air circulation and drainage
-
Poor Soil → Compost restores life to the soil and increases fertility over time
Your Soil, Your Success
A bit of preparation now leads to healthier, stronger lilacs for years to come. Whether you’re planting a single shrub or designing a long hedge, investing in your soil will always pay off.

Fertilizing Lilacs for Healthy Growth and Fragrant Blooms
(From the “How to Grow Lilacs” Series by 1st Choice Fertilizer)
Fertilizing lilacs can make a noticeable difference in their growth, bloom production, and overall plant health. While lilacs aren’t heavy feeders, the right fertilizer—applied at the right time—can help your shrubs reach their full potential.
Just like with any plant, soil testing is the first step. Whether you’re planting a lilac for the first time or maintaining an established shrub, understanding your soil’s nutrient levels will help you choose the right fertilizer and avoid overdoing it.
Why Fertilize Lilacs?
Fertilizer provides lilacs with the nutrients they need for:
-
Healthy new growth
-
Abundant and fragrant blooms
-
Strong root systems
-
Resistance to stress and disease
Lilacs benefit most from a balanced fertilizer with a moderate nitrogen level and sufficient phosphorus and potassium to encourage flowering and overall plant strength.
Key nutrients for lilacs:
-
Nitrogen (N): Promotes leafy green growth (but too much can reduce blooming)
-
Phosphorus (P): Supports root growth and flower development
-
Potassium (K): Enhances disease resistance and improves bloom quality
Look for fertilizers labeled with N-P-K ratios like 5-10-10 or 10-10-10, such as our 1st Choice Bloom Booster Blend, formulated for flowering shrubs.
Start With a Soil Test
Different soils can vary significantly—even within a single yard. Over-fertilizing can lead to lots of foliage but few flowers. That’s why we always recommend starting with a test using a 1st Choice Digital Soil Meter or sending a soil sample to your local Cooperative Extension.
If your soil is already rich in nitrogen, you may only need to add phosphorus and potassium for better blooms. If it’s depleted, a balanced approach will help restore vitality.
Fertilizing Newly Planted Lilacs
Lilacs planted in fertile, compost-enriched soil may not need fertilizer their first year. If they’re growing slowly or showing pale leaves, a gentle, slow-release fertilizer applied in spring can help.
Try 1st Choice Flowering Shrub Starter, a low-nitrogen formula designed for root development and early-stage flower support. It’s especially helpful when planting bare-root or container lilacs.
Fertilizing Established Lilacs
Once lilacs are well-established (typically after their second or third year), you can apply fertilizer annually to encourage bloom production and continued healthy growth.
Best Time to Fertilize Lilacs:
-
Early spring (just before new growth appears) is ideal
-
Avoid fertilizing after July 1st, as late feeding can encourage soft, frost-prone growth
For mature shrubs, use 1st Choice Bloom Booster Granules—apply around the base of the plant (at the drip line) and water deeply to help nutrients soak in.
⚠️ Avoid Over-Fertilizing
Lilacs are especially sensitive to excess nitrogen, which promotes lush green leaves at the expense of flowers. If your lilac is big and healthy but not blooming, too much nitrogen may be the reason.
Light Feeders vs. Heavy Feeders: Know Your Lilac Variety
Most lilacs are moderate feeders, but some hybrid or reblooming varieties benefit from a slightly more generous feeding schedule.
Light feeders (less fertilizer needed):
-
Classic single-season bloomers like Syringa vulgaris (Common Lilac)
-
Examples: ‘President Lincoln’, ‘Beauty of Moscow’, ‘Sensation’
Moderate-to-heavy feeders (respond better to regular feeding):
-
Reblooming or hybrid types
-
Examples: Bloomerang® series, Miss Kim, Tinkerbelle, Josee
If your reblooming lilac has limited second-round blooms, it may need a midseason phosphorus boost. Apply 1st Choice Flower Bloom Enhancer after the first bloom cycle.
Don’t Forget Micronutrients
Micronutrients like iron, calcium, and magnesium also support lilac health—especially in poor or sandy soils. Lilacs with yellowing leaves (chlorosis) may benefit from a micronutrient-rich amendment like 1st Choice Earth-Care Prime 5-8-8 with Iron & Calcium+.

Consistent care and early intervention are key to keeping lilacs pest- and disease-free. Healthy lilacs reward you with vibrant blooms and lush foliage year after year!
Watering Lilacs
(From Lilacs Pest & Disease Control – Tree Health & Protection Guide)
Lilacs are generally hardy and drought-tolerant once established, thriving well with typical rainfall in most climates. However, young lilac shrubs and those planted in sandy, well-draining soils or containers will benefit from thoughtful watering during their first year to encourage strong root development and vibrant blooms.
Watering Tips for New Lilacs
In the first growing season, keep the soil consistently moist—but avoid soggy conditions. Aim to provide about 1 inch of water every 7 to 10 days if natural rainfall isn’t sufficient. Deep, infrequent watering is key: use a slow trickle from a hose or a soaker hose around the base of the shrub to encourage roots to grow downward.
Avoid light, frequent watering that wets only the surface. This can lead to shallow roots and stress the plant during dry spells. Instead, water deeply once per week or every 10 days depending on your soil type and weather. Lilacs in clay soils may require less frequent watering, while those in sandy soils might need a bit more.
Watering Established Lilacs
Once lilacs are established (usually after one growing season), supplemental watering is rarely necessary unless you face prolonged drought or extremely hot weather. During such dry periods, deep watering every 2 to 3 weeks will support healthy foliage and flowering.
Additional Watering Tips
-
Mulch around the base of your lilacs to help retain soil moisture and moderate temperature fluctuations.
-
Avoid watering directly onto leaves to reduce the risk of fungal diseases.
-
If you create a shallow basin to catch water near the shrub, level it out before winter to prevent ice damage to roots and stems.
-
Observe your lilacs regularly: wilted or dry leaves during dry weather signal the need for more water.
-
Always adjust watering based on rainfall, soil type, and your specific climate conditions.
Note:
These are general guidelines. Soil moisture and plant health are your best indicators for when to water. Also, check local water use regulations during drought seasons to stay compliant.
Enjoying the Beauty of Your Lilacs: Blooming and Post-Bloom Care
(From the “How to Grow Lilacs” Series by 1st Choice Fertilizer)
After months of nurturing your lilac shrubs, the rewarding moment of vibrant blooms arrives! This is when all your care shows its results. To maximize the enjoyment and health of your lilacs, it’s important to know when they’re at peak bloom and how to care for them after flowering.
When Will My Lilacs Bloom?
Lilacs typically begin blooming within 2 to 4 years after planting, depending on the variety and growing conditions. With consistent care—proper watering, pruning, and feeding—your lilacs will develop fuller blooms season after season.
Recognizing Peak Bloom
Lilac flowers open gradually, often over a week or two in late spring. You’ll know your lilacs are at peak bloom when clusters of fragrant flowers fully open, showing rich color and sweet scent. Avoid picking or cutting blooms too early or too late for best fragrance and longevity.
Enjoying and Preserving Your Lilac Blooms
If you want to bring lilac beauty indoors:
-
Cut flower clusters just as the buds begin to open.
-
Place stems immediately in water to extend vase life.
-
Change water regularly to keep blooms fresh for up to a week.
Post-Bloom Care for Healthier Lilacs
Once flowering is finished, proper care will prepare your lilacs for strong growth next year:
-
Deadheading: Remove spent flower clusters to prevent energy loss and encourage new growth.
-
Pruning: Lightly prune dead or weak branches after blooming, but avoid heavy cuts until late winter.
-
Fertilizing: Apply a balanced fertilizer to support root and foliage development.
-
Watering: Keep soil moist but not soggy during summer, especially during dry spells.
Tips for Extending Lilac Life and Beauty
-
Mulch to conserve moisture and regulate soil temperature.
-
Monitor for pests and diseases and treat early if needed.
-
Avoid excessive nitrogen fertilizers, which encourage leaf growth at the expense of blooms.
-
Watch your lilacs each spring; timely pruning and feeding will reward you with more abundant and fragrant flowers year after year.
Enjoy your lilacs’ stunning show of color and scent! With proper care, your shrubs will be a highlight of your garden for many seasons to come.
