Veronica plants are beautiful and low-maintenance, but they can be prone to scale infestations. Scales are tiny insects that suck the sap from plants, causing yellowing, stunted growth, and even death. If you’ve noticed brown or black bumps on your Veronica plant’s stems or leaves, it’s likely that you’re dealing with scales. Fortunately, there are several methods you can use to get rid of them.
Before you start treating your Veronica plant for scales, it’s important to identify which type of scale insect you’re dealing with. There are two main types: armored scales and soft scales. Armored scales have a hard, protective covering that makes them difficult to kill, while soft scales have a softer, more vulnerable covering.
To identify the type of scale insect you’re dealing with, look closely at the bumps on your plant’s stems and leaves. If the bumps are hard and dome-shaped, you’re dealing with armored scales. If they’re soft and slightly flattened, you’re dealing with soft scales.
If you’ve identified armored scales on your Veronica plant, your best bet is to treat them with horticultural oil. This oil suffocates the insects by coating their protective covering and preventing them from breathing. To use horticultural oil, follow these steps:
It’s important to note that horticultural oil can damage some types of plants, so be sure to check the label before using it on your Veronica plant.
If you’re dealing with soft scales, neem oil is your best option. This oil is derived from the neem tree and works by disrupting the insect’s hormonal balance, causing it to stop feeding and reproducing. To use neem oil, follow these steps:
Neem oil is generally safe for most plants, but it’s always a good idea to test it on a small area before treating your entire Veronica plant.
If horticultural oil or neem oil aren’t effective at getting rid of the scales on your Veronica plant, you can try using insecticidal soap as a last resort. This soap works by suffocating the insects, much like horticultural oil, but it’s milder and less likely to damage your plant.
To use insecticidal soap, follow these steps:
Once you’ve successfully gotten rid of the scales on your Veronica plant, it’s important to take steps to prevent future infestations. Here are some tips:

Treat your plant every two weeks until the scales are gone. Be sure to follow the instructions on the bottle of whichever treatment method you choose.
Keep your plant healthy by watering it regularly and fertilizing it as needed. Remove any dead or diseased plant material from around your Veronica plant. Inspect new plants carefully before bringing them into your garden to ensure they’re free of pests. Monitor your plants regularly for signs of scale infestations so you can catch them early.
