Growing this spring - flowering shrub in Colorado is n’t that difficult , but there are still some things you need to look out for .
These perennial are incredibly fragrant , and they will festoon your front yard with their purple , pink , yellow , and white efflorescence in later spring .

Let ’s find out more !
Finding A Suitable Location
A good location is a key fruit to growing lilac in any United States Department of State , not just Colorado . This plant requires full sun to prosper , and anything below 6 hours of sunlight per twenty-four hour period will hinder its development .
Therefore , you must find a well - light location away from grandiloquent buildings and trees , which can all create darkness that prevent lilac bloom from appear when bloom time arrives .
Lilacs also care their secrecy , so growing them near foundations and trees can stunt their growth and preclude them from unfold their roots wider into the land .
take a smirch that ’s at least 5 feet away from anything that might prevent the lilac roots from expanding .
Lilacs require a few weeks of passing low temperatures , but glacial winds are a whole different story . rough winter gales can hurt these plants , so you should protect them with tree diagram wraps and mulch , and prune the debile ramification before the winds commence gas .
Colorado is n’t the most humid state of matter in the US , but the melody can still become saturate with moisture . As lilacs can not allow high humidity levels , you shouldensure there ’s enough airflow for the plant to breathe .
regrettably , common lilacs need tidy sum of space for their roots to evolve , so you may not grow them in containers . However , there are variety show idealistic for raft , and you’re able to always try grow them that manner to better your landscape design .
Soil Preparation
The next thing you need to give attention to is grime preparation . Lilacs can not mature in any old medium , so you should ensure that it is well - draining before plant .
In plus to respectable drain , the substrate for lilac plants needs to be plentiful , which is why adding compost and hommos before planting is something many growers around the world do .
There is n’t an exact amount of constituent cloth you should add to make the soil debilitate better . However , you may alwaystest the drainage and bit by bit add more compost , manure , chopped barque , etc . , ruffle it with the garden grease , and then prove it again .
Here are some tips for testing soil drain :
Instead of build a raise bed , which would be a pricy investment funds reckon that lilacs can get Brobdingnagian and spread their roots very far , you could make a mound or plant it on high ground .
Lilacs can not hold too much moisture in the filth , but if the only available spot for this works is near a pond , you should build up a three - animal foot tall mound of territory , gravel , compost , and manure .
Common lilacs are the most tolerant change when it comes to heavy clay soils , but not even they can tolerate a sloshed substrate .
Another soil necessity concerns the pH spirit level , and this plant can not thrive in acid culture medium , so you should always prove the grunge before planting . If the substrate is n’t indifferent or mildly alkaline , you’re able to always amend it by adding some lime tree .
Planting
Planting the common lilac shrub is n’t rocket science , but there are still some things you need to watch out for , such as the time of planting , spacing , profundity , etc .
You canplant lilacs either in spring or fall , and both have their benefits . Planting lilac in the fall before the soil freezes is the best option . These shrub are frigid - unfearing and in reality need many cold days to bring on the beneficial blossoms .
However , planting lilacs in the early spring is n’t the bad affair in the world , and you ’ll still have a feasible industrial plant that will raise purple - blue flowers .
you may practice either plant sucker from an already established bush or transplant a lilac from your local nursery .
If you wish to make a lilac hedge , you should leave 5 - 15 feet between each industrial plant so that the roots have enough room to grow .
The critical thing before planting is making certain that the soil is loose enough . If you contrive on produce a hedging or alley of lilacs , you should research sometillers for breaking new groundand either let one or kindly ask your neighbor to borrow theirs so as to get the job done cursorily and expeditiously .
There are many common lilac cultivars , many of which are available in Colorado . Their flower colors can be gloomy , purple , pinkish , or ashen . Some cultivar are grandiloquent than others , and there are some with fantastically fragrant flowers that nothing else can equate to .
Whichever variety you choose , planting suckers is virtually the same . After make the grunge , you need to dig a cakehole deep enough for the offshoot . Place the branch into the hole , fill it with soil , and ensure the gull can stand up on its own .
irrigate the offshoot thoroughly , and look . Lilacs take a tenacious time before they bulge producing flowers , and you ’ll probably have to wait 4 - 5 years before bask the Battle of Magenta - pinkish flowers of your Arch McKean cultivar .
The transplanting of nursery - bought lilac is n’t any more complicated than sticking a sucker into a deep enough hole in the garden soil .
You shouldplant your lilacs at least 2 - 3 inches deeper than they were when potted , so take this into consideration when digging the pickle . Spread the root gently , then simply direct the shoot into the ground .
If you start out your lilac organ transplant wrapped and lace , you shouldremove the dish and the R-2 before planting .
Cover the root word with some topsoil and water them thoroughly . After watering , add more ground to fill in the hole and then look .
Care Guide
Lilacs are popular in many countries , so it ’s not surprising that they have wriggled their way onto thelist of magical Gallic flush .
Common empurpled lilac are low - sustainment bush , but you still have to cope with their canonic requirements , including their need for light , water , and nutrient .
Of naturally , there ’s more to give care for lilac flower than just meet their basic needs .
That ’s why we are going to talk about everything you require to do in edict to savour their attractive flowers in Denver , Colorado Springs , Boulder , etc .
We already advert thatlilacs take full sunexposure for produce the best bloom , but what happens if it does n’t get at least six hours of sunlight each daytime ?
They will bring on fewer blooming , or maybe none at all , in shaded locations , and if you ca n’t remove the obstruction that ’s prevent the Sunday from have to your lilac , you ’ll have to move the shrubs themselves .
Lilacs can also get leggy if they do n’t get enough sun . They debase their stem in search of visible radiation , but if they do n’t incur it , photosynthesis slows down , energy and food become scarce , and the elongated branches become too intemperate for the plant life to carry .
Therefore , you must always see to it that there ’s enough sunlight before planting to avoid have to move the plant in the next year .
Lilacs are drought - kind industrial plant , but they still ask some water to go – peculiarly immediately after planting .
The soil should never be juiceless during this period , and you should water your lilac once or double a week in the first years of their life until they get established .
Young industrial plant are susceptible to drouth accent , so ensure that the soil is systematically damp during this fourth dimension .
establish plants do n’t require frequent watering , but they should still be irrigated once every 10 - 14 daytime . Water them deeply and allow the filth to somewhat dry out out between waterings .
Mature lilacs can not digest too much moisture in the dirt because water will fill up the zephyr pouch , and there would n’t be enough O to supply the integral plant .
The roots will begin to suffocate if this take place , and the first signs will be seeable on the industrial plant ’s leaves , which will bulge out wilt and become wan and yellow-bellied .
These plants can not tolerate high humidity , but that ’s a bonus because Colorado is n’t well known for humid summers .
If the atmosphere wet does get a moment too high , engraft these shrubs 5 - 15 feet away from each other will check right air circulation , and you wo n’t have to worry about too much moisture getting trapped between your plant life .
Lilacs are implausibly hardy plants and are favored by gardener around the world due to their ability to persist temperatures as down in the mouth as -35 ° F , although some varieties are pronounce to be capable to survive in much lower temperatures ( as broken as -60 ° F ) .
Freezing temperatures like this are n’t an emergence for lilacs , andthey actually need a couple of dusty week to be capable to produce flower .
They bloom in leap because the temperature are n’t exceptionally high , but scorching weather can not anguish this plant . It will still flower next class as long as the winters are recollective and inhuman .
Even though it seems like it can handle just about anything , lilac do n’t actually do well in winter wind , so make indisputable to protect them if your region is impractical .
You already know that lilacs favor well - draining soil , but we ’ll discuss these preferences in more detail in the following paragraph .
The Lilac shrub prefers a mildly acidic , neutral , or slenderly alkaline growing medium with a pH between 6.5 - 7.0.You should n’t implant it in acidic soils as they can hinder nutrient absorption and cause your industrial plant to wither .
gratefully you’re able to always add lime to frown the sour of the substrate .
When speaking about drain , we constantly spill about well - drain mediums . Most garden soils do n’t have suitable drainage , so you should amend them by sum compost or humus .
I once wonderedhow long it look at to make compost , but now I know that you could make it in three months and have enough for all your industrial plant . make humus takes a long time , but you could always buy some if you want to amend the soil with it .
Lilacs also need mediums copious in organic subject matter , so adding compost and hummus fulfill that requirement as well .
in the end , stiff soil wo n’t kill a lilac , but it might stunt its development . If you want to age as tight as possible , you should look at pass water dirt amendment .
Fertilizer
Almost all works benefit from occasional feeding , and the same goes for lilacs , especially if the grunge is n’t particularly rich in nutrients and constitutive material .
However , you should avoid fertiliser with high-pitched amounts of N as they will only direct to more vegetative growth and fewer flush .
Of course , you should n’t alone abstain from nitrogen as this mineral is responsible for offset and leaves , which are the main instruments of photosynthesis .
Therefore , you should use a well - balanced , general - purpose plant food such as triple 10 , or an constitutional fertiliser with mellow phosphorus levels to promote blossom .
Furthermore , lilac are n’t heavy feeders and only need to be fertilize once a yr in early outflow .
You do n’t have to feed this shrub in the first twelvemonth of planting , but add some hommos or compost to secure it has enough nutrients until the next year . In the leap of the second year of planting , you could add some slow - discharge fertilizer to sustain this plant life until the following year .
This is a truly easy - to - give care - for plant , and you do n’t have to eat it more than once a year .
Trimming lilacs is crucial as it can prevent legginess , increase prime bearing , and make the surrounding landscape more attractive . However , pruning this shrub requires a flock of strength , so you wo n’t be using simple hand pruners all the metre .
Lilacs set buds for the flowering of next twelvemonth after they wind up blooming , so you shouldprune them and deadhead the remaining blossom in spring , not later in the summer and fall . Summer and descend pruning will only lead to few blossom the next year as you ’ll remove most of the buds .
If the shrub has n’t outgrown its infinite , you could simply form it a bit and remove any morbid , dead , or broken stems . For lighter pruning , you’re able to use even pruners , and you’re able to always find somesecateurs for creaky handsas they normally do n’t stimulate too much air pressure on the joints .
Overgrown lilacs require more trimming and hack because the internal parts plausibly wo n’t bloom due to deficient light exposure . The branches are often woody and unsightly , and you’re able to take away them without worrying about harming your plant .
Use a byword to cut a third of all woody branches at least two inches in diameter . Repeat this process for the next three year so that the flora can bit by bit come back to lifeand retrieve its former glory . It will slow resume its full , bushy looks , and you ’ll remark unexampled ontogenesis every year .
If your shrub is too far gone , you’re able to polish off all woody staunch at once , but it will ask much more care , fertilizer , and piddle in the coming months .
If you still have some doubts about pruning , here ’s a TV to serve you get your shrubs in material body :
