Encouraging Your Lilacs to Bloom

The Syringa vulgaris, or lilac, is a beloved flowering plant that produces a range of beautiful colors and fragrances. While it’s easy to grow and maintain, if you want your lilacs to bloom at their very best, it’s important to follow some tips. Here’s how you can encourage your lilac bush to bloom.

Sunlight Is Key

One of the most important elements in getting your lilac bush to bloom is ensuring it has enough sunlight throughout the day. Lilacs require at least six hours of direct sunlight each day for optimal blooms. While some species may be able to survive with less sunlight, they will not blossom as well as they should.

Moving & Pruning

Sometimes, your lilac bush may not be receiving enough sunlight due to its placement or surrounding trees. In this case, you can try moving it or pruning back the trees blocking its sun exposure. It’s important to be aware that transplanting a lilac bush can delay its bloom for an entire year, so if possible, it’s best not to move it. If you do decide to transplant it, make sure it is done in late winter or early spring so that it can begin adjusting in time for summer blooms.

Thinning Out

In addition to providing adequate sun exposure, you may need to thin out your lilac bush in order for the light to penetrate through its foliage. This is especially true if your shrub has thick and bushy growth. Do this by removing some of the branches close together at the center of the plant and thinning out any overcrowded areas.


Fertilizing is also crucial when trying to encourage more blooms from a lilac bush. During springtime (March/April), apply a high-potassium fertilizer such as bone meal or wood ash around the base of your shrub and lightly rake it into the soil until it is no longer visible on topsoil level. You can repeat this process every few weeks until mid-summer (July).

Deadheading & Pruning

Deadheading (removing spent flowers) and pruning are two other essential steps when trying to promote reblooming with a lilac bush. Deadhead any faded blooms throughout summer while they are still fresh – this will help ensure that new buds form in their place instead of wasting energy forming seed pods as they would if left on the plant until they dry up completely. Lightly prune any overgrown branches after blooming season (August/September) which will help stimulate new growth for next year’s flowers as well as keep your shrub looking neat and tidy all year round!


Finally, watering correctly can also maximize blooms from your lilac bush! During springtime when leaves are budding, water frequently but lightly – about once every two weeks should be enough – so that soil remains moist but not soggy around plants root zone area (the area between trunk base and outer edge of branch tips). Then during summertime when flowers are forming, increase watering frequency depending on weather conditions – about once every week should suffice – so that plants don’t dry out too much before their next drink!


In summary, encouraging your lilac bush to bloom requires providing adequate sun exposure (at least 6 hours per day), moving or pruning back trees shading it, thinning out overcrowded areas, fertilizing with high-potassium fertilizers during springtime, deadheading spent flowers during summertime and watering correctly throughout both springtime and summertime! With these tips you should be well on your way towards having beautiful blooms from your beloved Syringa vulgaris!
