How to Get Rid of Scales on Foxglove Plant

Updated: September 15, 2022

Foxglove plants are beautiful and unique, with tall spikes of bell-shaped flowers. However, like many plants, they can fall victim to a variety of pests, including scales. Scales are tiny insects that attach themselves to the stems and leaves of plants, sucking out their sap and causing damage. If left untreated, scales can seriously harm your foxglove plant and even kill it. In this article, we’ll explore some effective ways to get rid of scales on your foxglove plant.

What Are Scales?

Scales are small, wingless insects that attach themselves to the stems and leaves of plants. They have a hard exterior shell that protects them from predators and pesticides. Scales can be white, brown, black or red in color, and they often appear in clusters on the plant. They feed by sucking out the sap of the plant, which can cause wilting, stunted growth, yellowing or browning of leaves, and even death.

How to Identify Scale Infestation on Foxglove Plants

The first step in getting rid of scales on your foxglove plant is identifying whether or not it has been infested. Here are some signs to look out for:

  • Small bumps or lumps on the stems or leaves
  • Sticky residue on the plant’s surface
  • Yellowing or browning of leaves
  • Wilting or stunted growth

If you notice any of these symptoms, inspect your plant more closely to see if you can spot clusters of tiny insects.

Natural Methods for Getting Rid of Scales

There are several natural methods you can use to get rid of scales without resorting to harmful pesticides. Here are some effective options:

1. Prune Affected Areas

One way to get rid of scales is to prune the affected parts of the plant. Use sharp, clean pruning shears to remove any stems or leaves that are heavily infested. Dispose of the pruned parts carefully, as scales can easily spread to other plants.

2. Use a High-Pressure Hose

Another natural method for removing scales is to use a high-pressure hose to spray the plant. This will knock off any scales that are clinging to the plant’s surface. Be sure to aim the hose at the underside of leaves and stems, where scales often congregate.

3. Apply Neem Oil

Neem oil is an effective natural insecticide that can help get rid of scales on your foxglove plant. Mix one tablespoon of neem oil with one quart of water and spray the solution onto the affected areas of the plant. Repeat this process every two weeks until the scales are gone.

4. Use Insecticidal Soap

Insecticidal soap is another natural insecticide that can help get rid of scales. Mix one tablespoon of insecticidal soap with one quart of water and spray the solution onto the affected areas of the plant. Repeat this process every two weeks until the scales are gone.

Chemical Methods for Getting Rid of Scales

If natural methods aren’t working, you may need to resort to chemical pesticides to get rid of scales on your foxglove plant. Here are some effective options:

1. Use Horticultural Oil

Horticultural oil is a type of pesticide that works by suffocating insects like scales. Mix one tablespoon of horticultural oil with one quart of water and spray the solution onto the affected areas of the plant. Repeat this process every two weeks until the scales are gone.

2. Apply Systemic Insecticides

Systemic insecticides are absorbed by the plant’s roots and circulate throughout its system, making it toxic to insects like scales. Apply systemic insecticides according to their instructions, being careful not to over-apply or damage the plant.
