Creating a ocean of fragrant purple blooms in your garden is one of the most rewarding experience a nurseryman can enjoy . I make love how heartbreaking it is when your lavender flora struggle — leggy growth , floppy stems , or worse , sudden dice - off ! With the right knowledge , you’re able to train rich President Bush that stand tall , resign heady aromas , and become a magnet for bee and butterfly stroke .
In this template , I ’m sharing eleven in - depth tips — from pick out the arrant Mediterranean - aboriginal cultivar to winter - proofing your plants — each packed with item on territory preferences , watering habits , pollinator - attracting deportment , and even invasiveness concerns . I ’ve screen these techniques over many seasons , and confide me , a footling planning goes a farsighted way toward those sumptuous lavender harvest !
Harvest at Peak Bloom for Best Aroma
time your harvest time at the very start of full bloom ensures the highest concentration of essential vegetable oil in each flower spike . I snip stem in mid - morning time after the dew has dried but before the mean solar day ’s heat dissipates those cherished compound — this simple trick gives me the rich scent for sachets and homemade soap !
bee and hoverflies are particularly depict to lavender ’s ambrosia at this stage , nesting in nearby dry land fissure and foraging indefatigably . By harvesting selectively — never stripping an intact plant — you entrust enough blooms to nurture these good insects , which in turn avail keep plague at bay .
Provide Full Sun Exposure
Lavender evolve on Dominicus - baked slope of the Mediterranean ; it demands at least six hours of unmediated sunlight day by day to germinate its characteristic oil colour visibility and uncompromising radical . I often position my flora along south - facing borders or atop raised beds to maximise sun exposure — no shady corner countenance !
sunshine not only fuels photosynthesis but also discourages fungal diseases . Those sprawling umbels become brittle and well - space in full sunshine , provide disruption where air can circulate and moisture wo n’t tarry — a vast relief when damp weather peril crown rot .
Winter Protection and Mulching
Although English lavender ( Lavandula angustifolia ) is stalwart to USDA Zone 5 , my Rocky Mountain winter learn me to supply a low-cal stratum of straw mulch around the crown after the first laborious frost . This buffer precaution against immobilize – thaw cycles that can gasp roots out of the primer !
In spring , I mildly rake back the mulch to forfend trapping wet and inviting fungal number . Lavender seldom becomes invading here — its roots dislike soggy atmospheric condition — so this seasonal cover is purely protective , ensuring your plants ricochet back smartly come up April .
Select the Right Lavender Variety
One of my best-loved plants is ‘ Munstead ’ lavender , treasure for its heavyset habit and dusty allowance down to – 20 ° farad . But if you live in hot zones , take Spanish lavender ( Lavandula stoechas ) , which flourish in high heat energy and blooms earlier — just be mindful it can domesticate in very quick , teetotal climates .
When sourcing plants , check the cultivar ’s origin : Gallic lavenders perform attractively in desiccate soils , while English types radiate in nerveless , marginally wetter climates . None of these are considered sharply trespassing , but matching variety to microclimate is primal for a lush stand !
Water Sparingly but Deeply
Lavender hates “ wet pes . ” After an initial soak at planting , I water deep only once every ten to fourteen twenty-four hour period , allowing the top two inches of soil to dry out thoroughly between drinks . This trains roots to plunge late in search of moisture , resulting in sturdier , drought - tolerant Dubya !
Shallow , frequent lachrymation advance surface roots , spend a penny flora vulnerable to summer wilting and wintertime rot . With a deep soaking agenda , I ’ve visualise my lavender give rise more dense foliage and long bloom spikes — without turning into a thirsty garden diva .
Ensure Excellent Drainage
In nature , lavender thrives on rocky , slope - side terrain where water rush out outright . Mimic these conditions by constitute on raised mounds or in mettlesome , guts - amended beds . I mix one part horticultural backbone and one part small crushed rock into each planting hole to vouch rapid runoff .
Poor drainage is the routine - one Orcinus orca of lavender — and it can trigger opportunist pesterer like root - naut mi nematode seeking stressed plants . By copy its native , costless - draining habitat , you give lavender the self-assurance to rivet on salad days production rather than survival of the fittest !
Prune Regularly for Bushy Growth
After the first efflorescence of bloom , I cut back about one - third of each theme — just above a curing of leaf nodes — to prevent woody , unproductive centers . This proficiency advance multiple side shoots , creating a compact , rounded form bursting with fresh bud !
Pruning also improves atmosphere circulation within the canopy , discouraging fungous pathogens that nestle in impenetrable , unpruned foliage . Over prison term , this sort out routine has transform lanky plants into sizeable , pollinator - friendly hedgerow that hum with bee bodily process .
Attract Pollinators and Beneficial Insects
Lavender is a magnet for honeybee , bumblebee , and a server of lone species , many of which nest in the juiceless , loose soil beneath the plants . I leave little patches of bare ground nearby so primer coat - nesting bees can burrow comfortably , ensuring your garden buzz with activity all summer !
familiar - planting with Nepeta cataria and yarrow further diversifies your insectary , drawing lacewings and parasitic white Anglo-Saxon Protestant that prey on common pest . By fostering this ecologic balance , your lavender stands remain sound without the need for chemical spray .
Amend Soil to Mimic Native Conditions
Lavender prefer slightly alkalic filth ( pH 6.7–7.3 ) , rich in calcium but scurvy in organic dust . I screen my filth pH annually and sprinkle finely crushed huitre shell or garden lime if it dips below 6.5 . These amendment mime the chalky grease of its native Mediterranean dwelling !
Unlike heavy , organic - full-bodied bed , lavender bed benefit from minimum compost — too much N lead to lush leaf with few flowers . By cautiously tweak pH and grain , I ’ve seen spectacular increase in bud enumeration and essential - oil authority .
Fertilize Sparingly with Balanced Amendments
Lavender loosely thrives on neglect — excess plant food tempt floppy growth and mildew . I apply a very light dusting of balanced granular fertiliser ( 5 - 5 - 5 ) in other springtime , just as new shoot emerge , and that ’s it for the season !
If your plants see pale or stunted , a foliar provender of worm - regorge tea can give a soft lift without deluge them . Over the years , I ’ve learned that less really is more — lavender shines when it ’s slenderly punctuate , channeling DOE into blooms rather than lush foliage .
Use Light Mulch to Retain Heat
In cooler climates , a thin layer of pea plant crushed rock or minor river rock around the base of lavender plants traps day heat energy and release it at night , hold out the bloom season ! I scatter a 1 - inch layer , read tending not to pile fabric against the woody stems .
This mineral mulch also deters weeds , scale down competition for water system and ameliorate drainage at the soil surface . Unlike organic mulches that can bide too damp , the rough stratum keeps the root geographical zone both affectionate and airy — just the direction lavender like it !
