Lilac Leaves Turning Brown

Lilac leaves are turning brown and I don’t know what to do. The leaves were green just a few days ago and now they’re brown and crispy. I water the plant daily and have been fertilizing it regularly.

I live in an apartment so I can’t take it outside to get more sunlight. What could be causing this problem?

Lilac leaves turning brown is not an uncommon occurrence. There are several reasons why this may happen, including disease, pests, or simply old age. If you notice that your lilac’s leaves are beginning to turn brown, don’t panic!

There are a few things you can do to help your plant. First, take a look at the overall health of your lilac. If it seems otherwise healthy, then chances are the browning leaves are not due to a serious problem.

However, if your plant looks sickly or has other symptoms such as wilting or yellowing leaves, then it could be suffering from a disease or pest infestation. In either case, it’s best to consult with a professional to get an accurate diagnosis and treatment plan. Once you’ve determined that the browning leaves are not indicative of a bigger problem, there are still a few things you can do to help your plant.

Pruning away any affected branches will help improve air circulation and allow more light to reach the remaining foliage. You can also try applying a fungicide or insecticide specifically designed for lilacs (be sure to follow the directions on the label!). Finally, make sure your plant is getting enough water – lilacs like moist but not soggy soil.

If you’re unsure whether yours is getting enough water, stick your finger in the soil up to the first knuckle – if it feels dry, give it a good watering. With proper care and attention, even plants with browning leaves can rebound and thrive!

Why are the Leaves on my Lilac Turning Brown?

Why are My Lilac Leaves Turning Brown?

If your lilac leaves are turning brown, it is likely due to a lack of water. Lilacs are drought-tolerant plants, but they still need regular watering, especially during hot summer months. Brown leaves can also be caused by too much sun exposure or by wind damage.

If you suspect that your lilac is not getting enough water, try giving it a deep watering once a week. Be sure to soak the roots thoroughly and avoid getting water on the leaves, as this can cause fungal diseases.

Why are My Lilac Leaves Curling And Turning Brown?

There could be a few reasons why your lilac leaves are curling and turning brown. One possibility is that the plant is not getting enough water. Make sure you’re watering regularly and deeply, especially during hot, dry weather.

Lilacs also need lots of nitrogen, so make sure you’re fertilizing regularly with a high-nitrogen fertilizer. Another possibility is that the plant is being damaged by insects or disease. Inspect the leaves carefully for signs of pests or diseases.

Common problems include aphids, scale insects, powdery mildew, and leaf spot diseases. If you see any evidence of pests or disease, treat accordingly with pesticides or fungicides. Finally, consider the possibility that the plant is simply too stressed and needs to be pruned back severely.

This will encourage new growth that should be healthier and more resistant to problems like curling leaves and browning tips.

How Do You Revive a Dying Lilac Tree?

When it comes to lilacs, the most common cause of death is planting them in the wrong location. Lilacs need full sun and well-drained soil in order to thrive. If your lilac is planted in a shaded area or has soggy soil, it will gradually start to die.

Another common cause of death is over-fertilization. Fertilizing your lilac too often can lead to its demise. If you think your lilac is dying, the first step is to check the planting site and make sure it’s getting enough sun and has well-drained soil.

If not, transplant it to a better location. If the problem appears to be over-fertilization, reduce the amount of fertilizer you’re using or stop using it altogether. Once you’ve addressed any issues with the planting site or fertilizer, give your lilac tree some water and time to see if it recovers.

If not, then unfortunately it may be time to say goodbye to your beloved tree.

How Can You Tell If a Lilac is Overwatered?

If a lilac is overwatered, the leaves will begin to yellow and drop off. The plant may also produce fewer flowers than normal. To check if your lilac is overwatered, stick your finger into the soil near the base of the plant.

If it feels soggy or wet, you need to water less often.

Lilac Bush Leaves Curling Turning Brown

If you have a lilac bush that is leaves are curling and turning brown, it is likely suffering from a fungal disease called lilac leaf blight. This disease is most common in late summer and early fall, when weather conditions are warm and wet. Lilac leaf blight can cause the leaves of your bush to turn yellow, brown, or black and curl up at the edges.

The affected leaves will eventually fall off the bush. If left untreated, lilac leaf blight can kill your entire bush. To prevent lilac leaf blight, make sure to plant your bush in an area that has good air circulation.

Avoid overhead watering and water only at the base of the plant. If possible, water in the morning so that the leaves have time to dry out before nightfall. Be sure to clean up any fallen leaves from around the plant as they can harbor the fungus that causes lilac leaf blight.

Finally, prune away any affected branches to help improve air circulation within the plant. If your lilac bush is already infected with lilac leaf blight, you can treat it with a fungicide containing copper or sulfur. Be sure to follow the directions on the label carefully and apply the fungicide every 7-10 days until the disease is under control.


If you have a lilac bush, you may have noticed that the leaves are turning brown. This is perfectly normal and nothing to worry about! Lilac bushes go through a process called dormancy, where they rest and regenerate for the winter months.

The leaves turn brown as part of this process, but they will be back to their green selves come springtime. So don’t fret if your lilac bush looks a little bare right now – it’s just getting ready for its winter snooze.
