Diseases Of Lantana Plants: Identifying Diseases That Affect Lantana


In the summertime, the leaves of lantana plants become dry and yellowish. They are not only dying off but they have turned completely black! When the temperature drops, it causes them to turn black too. You may think that this is just normal aging and nothing to worry about, but when the leaves die, it means that there is something seriously wrong with your plants.

The first thing you need to do is check if the problem lies in the soil or in the roots. If it’s in the soil then you will have to dig up all of your plants and replant them somewhere else where they won’t get wet. If the problem lies in the roots, then you’ll have to cut back on watering and fertilizing them.

If you live in a tropical climate, then you might want to consider moving your plants indoors. However, if you live in a temperate climate like ours, then your plants probably don’t need any special attention at all. You should water them in the morning and avoid watering them at night because the moisture will stay on their leaves all night, which can cause problems.

Another thing that you can do is put a shallow layer of mulch around the plants themselves. This will lock in the moisture and keep the roots from getting wet. Finally, add some Epsom salt to your soil. This will help reverse any magnesium deficiency that your plants may have. Magnesium is a vital nutrient that plays an important role in root growth and plant metabolism.


If your plants have white spots on their leaves, then they probably have a fungus infection which can be treated by dipping your finger in a very strong solution of water and chlorine and gently wiping the solution on the infected area no more than twice a day. It should start clearing up in about a week.

If you find that the infection is getting worse, then you will have to consider buying some fungicide at your local garden center and following the directions on the back of the bottle. If you find that this isn’t working either, then you may have to consider planting new lantana plants altogether because chances are the soil has been affected as well and is continuously giving off disease.

The best way to avoid these types of problems in the future is to make sure that you plant your lantana in well-draining soil. If the soil is too wet, it will promote the growth of fungus and other disease carrying organisms.

You can also add a layer of mulch around the plants themselves to keep the moisture locked in and keep the roots from coming into contact with water. If you see any worms or bugs on your lantana plants, then you will have to get rid of them immediately because these pests carry diseases which they will inevitably pass on to your plants.

Other Problems With Lantana


One of the biggest problems with lantana is that it seeds everywhere and it is almost impossible to get rid of. If you see any loose seeds on the ground, you will have to cover them up immediately with dirt or mulch to prevent them from growing.

You can also pick off the flowers when they start to bloom and throw them in the garbage. Lantana doesn’t produce many flowers, but even a few can lead to hundreds of new plants.

One way that you can prevent lantana from growing altogether is by keeping the area around your garden free of any plants whatsoever. Lantana loves to grow in empty spaces, so if you have a healthy garden with no bare spots, then the lantana will most likely not be able to gain a foothold.

If you don’t have enough time to garden, then you will have to prioritize.

Is your lantana problem really that bad?

If not, then it might be better to concentrate on other areas of your garden that are more important or in worse condition than the lantana.

Before you do any weeding, inspect your garden and consider WHY the lantana is growing in certain areas. If it is growing in a certain area, then there is a reason for it such as the soil is richer there or it gets more sun. If this is the case, then it might be better to leave it alone and plant other types of plants that will thrive in that particular area.

If yard space is an issue for you, then you will have to clear some of it out, orchard grass is a fast growing grass that can be mowed over and it provides excellent grazing for animals.

Ornamental white clover is another good choice as it fixes nitrogen in the soil and rabbit’s love to eat it.

Butterfly weed is also a great plant to grow if you want to attract more butterflies to your garden.

The soil in your lantana patch is very fertile, so you might want to get a rototiller and till the topsoil from the lantana and use it to cover any bare spots in your lawn.

Another option would be to take away their sunlight by laying down some chicken wire or even cardboard on top of the ground. This will block out the sun and eventually the lantana will die due to lack of sunlight.

You can also use grass killers, but these are not recommended as they can kill off your other grasses and plants that you do want to keep.

And of course you can always just start over!

Why not plant a garden full of flowers and plants that you DO like?

If the problem is really bad, you will probably have to get a little more aggressive in your approach.

But why not try some of the other suggestions first?

What Is Lantana Good For?

Other than looking nice, lantana is one of the most drought tolerant flowers out there. It can survive in almost any type of soil. It grows well in poor soil, and its roots reach deep down into the ground to extract moisture from deeper layers of soil.

Lantana makes an excellent nutritious snack for animals and it can even be used as fodder. It is a great addition to any garden as it helps to attract butterflies, bees, and hummingbirds.

It’s hardy nature makes it a popular addition to landscaping in cottage gardens. Many people also like to grow it in pots so that they can move them around for decoration.

Lantana: When Not to Plant

There are several times of the year that you should not plant lantana. It should not be planted in the spring or summer. These are the times of year when lantana is naturally growing and you will have better luck with success if you plant it during the fall or winter months.

Lantana: Where to Plant

Lantana grows best in USDA hardiness zones of 10b through 11. This means that it can withstand cold temperatures as low as 5 degrees Fahrenheit. It can grow in a wide range of soil conditions and does not require much moisture to thrive, so long as it is not allowed to dry out completely.

Lantana flower can thrive in partial shade or full sunlight. You will have the best results if you give it six hours of sunlight each day.

Children should always be carefully supervised when around plants. Keep lantana out of reach of small children who might find the berries appealing, but highly toxic. Deer and other wildlife may graze on your lantana so it may be best to protect it by placing a fence around it.

How to Plant Lantana Seeds

Lantana seeds are best planted in the fall when you can give them the most warmth possible. To prepare your lantana seed bed, you will first need to rake the soil. Use a garden trowel to make shallow furrows in the soil.

These furrows should be around 4 inches apart from one another. You can create these furrows by dragging the tip of the trowel through the soil or you can simply use your hands to make shallow trenches in the ground.

Once you have made these shallow furrows, you can place your lantana seeds inside. Cover the seeds with a fine sprinkling of soil. You should lightly water the soil after you have planted your lantana seeds.

You can also plant your lantana seeds in a starter pot with potting soil. Keep the soil moist but not soggy. Lantana seeds need to be kept consistently warm in order to germinate, so it is best to place the pot somewhere where it will get sunlight or heat from another source such as a heating pad.

You can also start your lantana seeds indoors in a cup or shallow pot and transplant them after their roots have developed and the risk of frost has passed.

How to Grow Lantana

Lantana is a quick growing plant. Once your lantana seeds have sprouted, it shouldn’t take more than a few weeks for them to reach a size that you can transplant them outside in your garden.

Lantana can also be propagated by cuttings. Take a cutting from a healthy lantana plant and strip all of the leaves off of it except for the topmost set. Place the cutting in a cup or container with moist soil and keep it in a warm area that receives sun. The cutting should root itself in a few weeks. Transplant it into your garden after all chance of frost has passed.
