Updated: April 25, 2023

Foxglove plants are beautiful biennials that can add color and height to any garden. However, they are also susceptible to thrips infestations, which can damage the leaves and flowers. Thrips are tiny insects that feed on the sap of plants and can cause significant damage if left untreated. In this article, we will discuss how to get rid of thrips in foxglove plants.

Identify Thrips Infestation

The first step in getting rid of thrips is identifying their presence. Thrips are tiny insects, and they are challenging to spot with the naked eye. However, you can look for the following signs:

  • Distorted or discolored leaves
  • Silver or bronze streaks on leaves
  • Deformed flowers
  • Presence of black feces on leaves or flowers

If you notice any of these signs, it is highly likely that your foxglove plant has a thrips infestation.

Prevention

Prevention is always better than cure, and this holds for thrips infestation as well. Here are a few things you can do to prevent thrips from attacking your foxglove plants:

  • Keep your garden clean and remove any debris or dead plant material.
  • Avoid over-fertilizing your plants as it can attract thrips.
  • Use drip irrigation instead of overhead watering to avoid creating a humid environment that thrips love.
  • Plant companion plants like petunias, marigolds, or calendula around your foxglove plants. These plants attract beneficial insects that prey on thrips.

Treatment

If your foxglove plant already has a thrips infestation, you need to act fast to prevent them from spreading to other plants in your garden. Here are some ways to get rid of thrips:

1. Pruning

Thrips tend to congregate on the undersides of leaves and in the flowers. You can prune off the affected leaves and flowers to remove the thrips. Make sure to dispose of the pruned material away from your garden to avoid spreading the infestation.

2. Insecticidal soap

Insecticidal soap is a non-toxic, effective way to get rid of thrips. Mix a few tablespoons of insecticidal soap in a gallon of water and spray it on your foxglove plant, making sure to cover both sides of the leaves. Repeat this process every 7 to 10 days until the infestation is gone.

3. Neem oil

Neem oil is an organic solution that works by suffocating thrips. Mix one tablespoon of neem oil with a gallon of water and spray it on your foxglove plant. Repeat this process every 7 to 14 days until the infestation is gone.
