Lilac Blossoms

There is possibly no greater bloom than the lilac! All those little flowers blooming together to create a beautiful ombre bundle that seems to almost overflow from the bush itself! I am so lucky to live in a zone where Lilac blossoms grow easily and hedges get bigger with more blooms every year!

Lilacs come in all sorts of pretty colours from muted pinks and whites to deep magentas and beautiful blues, but my favourite colour is the prestige purple lilac. I love to bring big bunches into my home to enjoy throughout the lilac season! Here is a detailed care guide to help you make those big beauties last as long as you can!

Blooming Time for Lilacs

Depending on what gardening zone you live in, lilacs will bloom reach their peak from May to late June and even into early July if the season is late. Here in central Alberta, Canada, we are a Zone 3 and can enjoy blooming lilacs into the beginning of July most years. The higher your gardening zone, the earlier your lilacs will bloom.

Can you eat lilac blossoms?

Yes! Lilac blossoms are in fact edible! They smell much better than they taste but it is still fun to use them as a lovely spring garnish for a salad or to infuse them in your lemon water.  You could also try making a recipe for lilac tea!

Typically a lilac bush will bloom for around two weeks. The timing of the blooms are dependant on the variation of the lilac. Once a lilac stem is cut, it will last approximately 2 days to a week. Follow the tips below to prevent your lilacs from wilting once they are cut!

The Best Fertilizer For Lilacs

Lilacs don’t require a lot of fertilizer or feeding to grow however if you are going to fertilize, use a 10-10-10 mixture applied annually in early spring. You can also use organic fertilizers such as Epsom salts, coffee grounds and bananas as natural alternatives.

How long will cut lilacs last in a vase?

While lilacs look lovely outside, we all love to bring them indoors and have lilac arrangements in a vase or bucket! The scent of lilac fills our entire homes and they look amazing just as single stems or as a large lilac arrangement! The problem is that lilacs don’t last long once brought indoors, so here are a few tips to help maximize the life of a cut lilac. To be completely honest, these tips are not guaranteed and you will be lucky to get cut lilac blossoms to last three days to a week, but give it a try anyways! The smell and beauty of lilacs are totally worth it!

How To Keep Cut Lilacs From Wilting

Here are a few steps you can take to make your lilac blossoms last longer and prevent them from wilting. 

Harvest Lilac Blossoms In The Morning

The optimal time is in the morning after it has been cool all night.

Cut When 3/4 In Bloom

It is best to harvest lilac blossoms when the stem is about 3/4 blooming. This seems to be the time frame that the blooms will last the longest! 

Place In Water Immediately

Place the cut lilacs in water immediately. When you cut the lilacs have a bucket of cold water ready! Immediately cut and get the branch straight into the water! Some people even submerge them in water once they begin to wilt to try and rehydrate the bloom.

Cut Large Lilac Branches

If you are able to, we recommend cutting larger branches as opposed to just the small single stems of lilacs. Displaying larger buckets of lilac blossoms is beautiful and we have more success with them this way!

Keep The Blooms Cool

Keep lilac arrangements out of the direct sun and then set them outside or in a cold space at night!  The cool air will help revive the wilting blooms, then first thing in the morning, bring them back in and continue to enjoy the amazing aromas. You can also store them in a refrigerator. 

Don’t Touch The Lilac Arrangement

Look but don’t touch! Leave cut lilac arrangements alone once you have arranged them. After you cut the lilacs place them immediately into the water and if you are putting them in a different container transfer them without trimming them! Re-trimming seems to only stress the blooms out! So simply cut and enjoy!
