General Maintenance Pruning
When to Prune Lilacs
Lilacs should be pruned right after they fetch up blooming , which is usually in late spring or former summertime . This timing ensures that you wo n’t cut off any of next yr ’s flower bud .
If you look too long to prune , you lay on the line removing the buds and potentially missing out on next class ’s blooms .
How to Prune Lilacs
Start by take away any numb or discredited wood . Then , take out most of the suckers that have produce around the al-Qa’ida of the industrial plant .
These are shoots that grow up from the root . Leave a few to replace old or dying limb that may require cutting to the ground .
snip out old cane or branches turgid than 2 inch in diameter .
Next , take away any offset that are rubbing against each other or growing inwards toward the nitty-gritty of the industrial plant . This will open up the plant and admit for well air circulation , which can help prevent diseases .
at last , forge the plant by selectively removing some of the branches . This will elevate young growth and help the plant maintain its shape .
Other Reasons to Prune
the Lilac has been neglected for years
Common Lilacs can last for decades but they bloom well on wood that is under 5 to 6 eld erstwhile . They will bloom less and less on wood that is older . Plus the blooms are commonly too high to enjoy once that old .
For older lilacs that have not enjoyed good yearly sustenance a more severe renovation prune is in order .
A adept meter to do this is in tardy winter before new increase begin when the lilac is dormant .
you may prune the full plant back 6 to 8 inch from the ground . This is a very spectacular method acting and you wo n’t most probable not see bloom for 2 years but it works .
Note : Check to see if your lilac has been grafted . check off the primary bole of the Lilac and see if there is a blow and divergence in the bark . That would be the transplant sum .
graft is where you link up a scion of one cultivar to the rhizome of another . If you attain it is a grafted Lilac be sure to take away all suckers from around the base .
Never cut the lilac itself below the bribery joint . The shoot or suckers coming up around the base of operations of grafted Lilacs will not be the same bloom character .
Less intense renovation prune
you’re able to also do a renovation prune over a 3 - class period . When crop this way cut out any numb or decrepit canes , then hack out 2/3rds of the suckers or shoots coming up at the base , leaving 1/3 for future flower stems .
take note : Check out how to propagate Lilacs from gull ! It is a quick way to get more plants !
you’re able to actuallydig the suckers up and pot them to make more lilacs if you like , they actually mature quicker than taking cuttings and rooting them .
Cut back 1/3 of the sr. lilac canes or branches . The following class rationalise out the next 1/3 of the old branches then the final year tailor back the last of the erstwhile branches .
Doing this in 1/3 ’s will let you have blooms and still make out back the one-time worn - out branches fully renovating the lilac .
Some say to have only about 10 canes per bush for best health and others say 2 or 3 . The lilacs I have cared for have between 5 and 10 canes and flower attractively .
Deadheading Lilacs
Cutting Lilac blooms to bring into the house is a great way to keep your plant intelligent . Make the undercut at the base of the flowers . This is alike to deadheading but you are cutting off the flowers before they are dead .
The beauty of cut the bloom is you keep spent flower from sucking energy from the residuum of the lilac . And you get to enjoy their sweet-scented perfume in your nursing home .
Deadheading should be done as soon as potential after the flowers fade if you have n’t already trim back them to bring into the house .
The old peak cluster should be cut off at its base , just above the two new shoot that angle out from the stem that ended with the old flower .
New shoot will grow over the summer , fix flower bud , and bloom the following spring .
Just after they flower is also when you cut out unproductive , ill-shapen , and obviously diseased stems to the ground . Twiggy growth should also be removed .
Thin and slay some canes to give proper spacing for healthy airflow , get robust growth .
reduce out suckers straying too far from the plant , dilute them to earth grade . I have say that the lollipop or shoots that maintain a pencil thickness all the elbow room to the baksheesh are the most productive but I have n’t tested that myself . Keep a well few inches between suckers or shoots .
Tipping
Tipping is when you cut back to a pair of side shoots instead of at the base of the spent blossom .
You will ask to do this if you get a stem that burgeon forth higher than the balance qualification for an uneven plant . The welfare of tipping is not only a well - shaped lilac but the side shoots will put out new growth and peak bud for the following year .
I do n’t give a particular month or date as the bloom time of your Lilac can be quite dissimilar than mine . Here we typically do n’t see lilacs blossom until well into May while just 10 minutes down the route from me they flower in early April .
Thus the one-year pruning time frame is different for each locating .
The dwarf lilacs do n’t need much pruning . Just deadhead each twelvemonth to keep bang-up and tidy . Miss KimandBloomerang Dwarf Lilac(reblooming )
