One of my favorite summer memories from childhood is helping my grandmother prune her large garden of fragrant Spanish lavender bushes. As I inhale the soothing scent released into the air with each snip of the pruning shears, it instantly transports me back to that peaceful time we shared nurturing her beloved plants.
Pruning Spanish lavender correctly is crucial for maintaining its attractive shape and encouraging prolific blooming for many years to come. In this article, I will provide a comprehensive guide covering everything you need to know on how to prune Spanish lavender.
Understanding Spanish Lavender
Characteristics
Spanish lavender grows into neat, compact mounds between 2-3 feet tall and wide with aromatic gray-green foliage. The leaves are narrow, elliptical and arranged in whorls around the stem. In summer, Spanish lavender produces abundant pale purple flower spikes which emerge atop slender stems rising just above the foliage. Each spike contains numerous small florets that resemble a bottlebrush in appearance.
The blooms emit a sweet, herbaceous fragrance reminiscent of citrus and spice. This soothing scent has made Spanish lavender beloved for sachets, soaps, perfumes and other body products. Some describe its perfume as powdery, creamy lavender with subtle notes of woody spice. The flowers also attract beneficial pollinators like bees, butterflies and hummingbirds to the garden.
Spanish lavender is actually a hardy hybrid between English lavender and French lavender. It exhibits characteristics of both parents, such as English lavender’s gray foliage and French lavender’s resistance to frost, heat, and drought. This hybridization results in a varietal perfectly suited to growing zones 5 through 9 across much of the United States and Canada. Spanish lavender proves very tolerant of drought once established, requiring little water except during long stretches of hot, dry weather.
The compact, mounded habit formed by Spanish lavender makes it an excellent choice for borders, cottage gardens, containers or mass plantings. Mature bushes normally reach 24 to 30 inches in height and spread an equal width. Regular pruning plays an important role in maintaining this neat, tidy form suited to many landscape designs. With its low maintenance needs and profuse blooming over many months, Spanish lavender offers wonderful curb appeal and sensory delight in the garden.
Benefits of Pruning
Pruning Spanish lavender correctly on a regular schedule has numerous benefits beyond just shaping the plant. Proper trimming is essential for encouraging strong, vivid growth and ensuring robust re-blooming throughout the growing season. Without selective pruning, Spanish lavender risks becoming woody, unkempt and leggy with scrawny blooms facing inward instead of outward. This ruins the plant’s compact, mounded habit so prized by gardeners.
Pruning removes dead, diseased or aging wood that saps the plant’s vigor if left to accumulate. By eliminating such weak, unproductive material, energy is redirected to fuel new stems and an even more prolifically flowering display. Thinning out some of the previous season’s growth also creates important room for improved airflow and light penetration down to lower foliage levels. This reduces the chances of mildew, mold or other fungal issues retaining moisture in the dense interior of the bush.
Perhaps most importantly, pruning stimulates production of Spanish lavender’s alluring fragrance. As anyone knows who has walked through a freshly trimmed garden of it, each snip of pruning shears releases more of the plant’s delightful perfume into the air. Regular deadheading and selective thinning prevents blooms from going past their prime fragrant stage too quickly as well. Proper pruning thus helps Spanish lavender fully shine with its alluring visual and aromatic qualities beloved by humans and pollinators alike.
Timing
The best time to prune Spanish lavender varies slightly based on whether the plant requires light seasonal trimming or a more heavy-duty reshape. For established plants in their primne, standard light pruning is best performed in late spring once flowers have finished blooming and seeding from the initial spring flush. This allows the lavender to gather sufficient strength from sunshine and rain over the next few months.
Pruning at this stage removes any dead or weak wood accumulated over winter before new growth commences. It also shapes the plant for lush development over the duration of the growing season. Late spring timing means gardeners can still enjoy the fragrance released with each snip of the shears as well. Pruning avoids excess stress to the plant by not interfering with its dormancy over winter or the critical blooming period in early summer.
Heavier pruning aimed at thorough rejuvenation or reshaping an overgrown lavender is best left for late winter when the plant has fully dormant for several months. The optimal window is early February through the end of March before buds begin to swell with rising temperatures. Waiting until dormancy gives the plant the entire spring, summer and fall to recover before the next winter sets in. Late winter pruning thus encourages vigorous regrowth and primne flowering the following season.
Tools and Equipment
Pruning Shears
The most basic and important tool for pruning Spanish lavender is a high-quality pair of bypass pruning shears. Bypass pruners, also called anvil pruners, make clean cuts close to the stem without crushing or tearing plant tissue like scissor-action pruners can. Clean, healed cuts allow pruned branches to dry out and seal over naturally rather than becoming entry points for infection.
Look for pruners with long, sturdy hardened-steel blades that won’t bend or lose an edge easily even with extensive use. The handles should provide a comfortable, secure grip even during lengthy pruning sessions. Always store pruners in a dry location protected from rust and clean/disinfect the blades monthly with a dilute bleach solution or rubbing alcohol. Replacing worn blades yearly helps ensure cuts remain precise and prevent injury to fragile plant material.
Sharp, well-maintained pruners result in clean pruning wounds that heal rapidly. This promotes vigorous regrowth and flowering rather than stressing the plant. Dull tools cause jagged, damaged pruning that may weaken Spanish lavender and leave it prone to diseases over time if wounds fail to close properly. Using high-quality pruners is paramount for the health, aesthetics and longevity of any pruned landscape plants including beloved Spanish lavender.
Gloves
Gloves provide important protection when pruning concentrated sources of aromatic essential oils like Spanish lavender. While relaxing and uplifting when diluted, concentrated lavender oil can irritate delicate skin after prolonged exposure. Thin latex or nitrile gloves prevent direct skin contact that risks provoking rashes, itching or swollen hands from the plant’s natural defensive compounds.
Look for form-fitting gloves allowing freedom of movement and dexterity without restricting feel and functionality of pruners. Avoid thicker work gloves that may slip or cut off sensitivity. Gloves should be easily washed and reused for multiple pruning sessions. Dispose of any showing signs of oil saturation that could still transfer to skin. Basic hand protection enables long, comfortable pruning stints while preserving gardener well-being.
Other Tools
A few additional tools prove useful accessories during Spanish lavender pruning and maintenance. A garden rake efficiently collects prunings and leaf litter for disposal or composting. A hose with adjustable nozzle stream comes in handy for rinsing dirt and debris from pruners between different plants. This simple step prevents potential cross-contamination of any pathogens, insects or plant oils between individual lavender specimens.
Collapsible pruning saws or loppers can tackle thicker, woody growth too robust for hand shears. And although not strictly required, knee pads, pruning stools or tarps for kneeling provide more ergonomic comfort during lengthy sessions working at ground level around Spanish lavender. Optional tools augment the primary necessities of high-quality pruners and gloves for safe, effective results.
How to Prune Spanish Lavender – Deadheading and Light Pruning
Removing Spent Flowers
Deadheading spent blooms from Spanish lavender requires little more than a gentle pinch or snip just above a leaf node or set of leaves directly below the dead floral spike. This encourages bushier regrowth and signals the plant to concentrate efforts on producing new buds lower down stems. Deadhead regularly throughout the growing period, at minimum once every 7-10 days, to prolong Spanish lavender’s flowering display through summer and fall.
The best technique uses pruners to grasp the dried bloom cluster firmly near its base, giving a short sharp downward snap to sever it cleanly. Avoid pulling or twisting which risks damaging succulent new growth points. Work systematically through the entire plant removing any blooms looking fully past their colorful prime. Carry a small bucket along for collected prunings, emptying it periodically to avoid leaving flower debris strewn on the ground as an eyesore or pathology harbor.
Some gardeners even deadhead Spanish lavender in batches on alternating sides of the plant weekly for an extended season of beauty. This judicious flowering stimulation coaxes otherwise bashful later blooms out of hiding. Either way, attentive deadheading represents the simplest yet most impactful way to boost Spanish lavender’s ornamental allure and fragrance payload season after season with very little effort.
Light Annual Pruning
While deadheading removes spent floral material, light annual pruning shapes and revitalizes Spanish lavender on the bush level. The optimal window is late spring once initial flowers have finished blooming and deadheading commences. Using sharp pruners, carefully snip off approximately one third of each new season’s woodyl growth throughout the plant. Distribute prunings evenly rather than shearing all growth to the same height or length.
Selectively thinning individual stems in this manner maintains Spanish lavender’s naturally full, rounded form without creating an unnatural clipped appearance. It also prevents wind rocking dry, leggy growth prone to breaking. Prune back to outward facing buds, being careful not to nick tender new growth just emerging. Like deadheading, carry a bucket and dispose promptly of prunings which can harbor diseases if left lying about.
With light annual pruning, Spanish lavender retains a neatly sculpted yet free-flowing rounded shape up to 2-3 feet tall and wide. Internal light access and airflow inhibit fungus and pests while devoting carbohydrates to developing even more fragrant blooms. Repeating this maintenance each late spring keeps plants compact, vigorous and floriferous for many prosperous years.
Heavy Pruning for Rejuvenation
When and Why
While light seasonal pruning preserves Spanish lavender’s good habits long-term, occasionally a hard prune becomes necessary for real transformation and renewal. Factors signaling the need for rejuvenative heavy pruning include:
- Woody, leggy interior stems choking out new growth
- Sparse, poor quality blooms lacking fragrance
- Overly large size constrained by available space
- Spreading desperately need reining back in
- General signs of decline like disease, dieback or pest infestation.
At this point, Spanish lavender has exhausted its primes and diverted energy into unproductive old wood best removed. The optimal time for heavy renovation is very late winter/early spring once plants have been fully dormant for 4-6 weeks with no risk of freezing temperatures returning. This long phase of rest and renewal sets them up for vigorous bursting forth in their refreshed glory.
Pruning Technique
The goal with heavy pruning is invigorating Spanish lavender from the ground up for luxuriant regrowth. Using hand pruners, sweep all growth back to within 6-8 inches from soil level. Where particularly thick, woody canes emerge, consider removing some entirely down to the base or crown. Leave generous fresh stems in an open cage shape rather than lollipop head to encourage sturdy regrowth.
Rake away all prunings, getting down even to last year’s leaf litter and debris that may harbor issues. Finally, give remaining stems a shaping trim as per light annual pruning guidelines if needed. The rejuvenated Spanish lavender is now primed to bounce back bushier and more floriferous than ever with the proper aftercare detailed in the following sections. Patience through its renewal phase yields lavish rewards!
Care After Pruning
Watering
Ensuring adequate hydration benefits newly trimmed Spanish lavender as it redirects energy into regrowth and healing of pruning wounds. During active growth periods in spring and summer, regularly monitor soil moisture and water deeply whenever the top few inches begin drying out. Aim to supply approximately 1-2 inches of water per week to newly pruned plants, including supplemental irrigation if rainfall proves insufficient during heatwaves.
Overly wet soils cause as many issues as dryness, so allow complete draining between waterings. Never allow pruned lavender to sit in pooled water which can lead to crown and root rot diseases. As plants become reestablished later in the season, reduce watering frequency but do continue monitoring and applying deep drinks about once weekly if rain is lacking through the end of summer. Proper hydration speeds the pruning recovery process.
Fertilizing
Apply a balanced, water-soluble plant food every 2-3 weeks during the growing period to nourish Spanish lavender through its renewal phase. Especially after heavy pruning removes stored nutrients, fertilizer replaces essential minerals like nitrogen, phosphorus and potassium required for lush regrowth and blooming. Mix products as directed, applying only to dry soil and watering thoroughly afterward to avoid burning newly emerged foliage.
Fertilizing complements watering in fueling robust regeneration from trimmed back plants. Lavender divert significant resources into producing new stems and foliage to replace what pruning removed, so extra nutrients reward their reinvigoration efforts handsomely. Maintain this routine through late summer or early fall depending on your region’s seasons.
Pest and Disease Management
Closely monitor newly trimmed Spanish lavender for any pests or issues taking advantage of its temporary weakened state. Common threads include spider mites, powdery mildew, leafhoppers and various fungal rots if soils remain too wet. At first signs of an outbreak, promptly address the problem following integrated pest management practices best suited to your individual situation.
Natural remedies like neem oil prove effective against many soft-bodied insects when applied early. Fungicides labeled for ornamentals treat powdery mildew. For severe rot, remove affected material and improve drainage. Preventive sprays of insecticidal soap also offer protection. Catching issues in initial phases allows easy control before significant plant damage occurs. Healthy Spanish lavender then bounces back to primne with exemplary aftercare.
Additional Considerations
Pruning Dwarf Varieties
Spanish lavender comes in compact dwarf cultivars suited to containers, edging or other tight spaces. While following general pruning principles, take extra precaution not to over-trim dwarfs due to their restricted size. Practice deadheading spent blooms and selective thinning of approximately 10-15% growth each time rather than heavier reductions.
Start shaping while bushes are young before woody stems develop fully. Dwarfs also require more shelter from harsh sun/winds which drying pruning wounds. Use a diluted seaweed-based fertilizer tailored for delicater plants. Give dwarfs preference for richest, well-drained soil and consistent moisture where their fine root systems cannot range as widely as standards. With gentler care, dwarfs rewardfocused efforts with vibrant fullness.
Pruning for Hedges
Prolific bloomer ‘Wynn’ makes a superb informal edging or hedge plant for borders and walkways. Trim all-over after deadheading spent flowers down to a uniform height and spread using loppers, saws or shears. Renewal pruning every 2-3 years reinvigorates these living Barriers for optimal density if plants start to thin in sections.
Feed regularly with dilute fertilizer to promote robust foliage coverage. Hedge trimming suppresses lavender’s natural form so avoid if appearance matters more than function. Space plants 12-18 inches on center for fast filling in. Staking the first year assures straight growth before plants mesh together wind resistant. Neat, fragrant hedging adds lasting beauty!
Pruning for Bonsai
With regular training, Spanish lavender lends itself well to becoming a living work of horticultural art. Start by pruning newly rooted cuttings back to a single framework branch or node using sharp, concave-edged detail pruners. Gradually refine branch structure and shoots over years applying bonsai styling principles like ramification, reverse taper and overall balance.
Keep container very shallow to restrict roots encouraging miniaturization. Supplement organic potting soil with akadama or pumice for enhanced drainage essential to bonsai culture. Never repot in spring, only when roots overfill the pot in fall/winter. Light, well-timed pruning tips keeps bonsai Spanish lavender properly stunted yet lushly leafed and flowering. Display enhances any space with delicate fragrance!
Conclusion
In conclusion, with proper pruning Spanish lavender can thank you with many years of lovely mounding habit and abundantly fragrant blooms to enjoy. Remember to use sharp shears, deadhead regularly and refresh plants periodically or as needed. Correct pruning is the secret to thriving lavender!
I hope you now feel confident putting these pruning techniques to use in your own garden to coax the very best from your Spanish lavender. Be sure to savor that soothing aroma as you nurture these beautiful flowering bushes!
