How to Get Rid of Borers on Gopher Plant

Gopher plants, also known as Euphorbia lathyris, are striking ornamental plants that are commonly found in gardens and landscapes. Known for their tall spikes of green flowers, gopher plants are a favorite among gardeners. However, these plants are prone to infestation by borers, which can cause significant damage to the plant. In this article, we will discuss how to get rid of borers on gopher plants.

Identifying Borers on Gopher Plants

Borers are small insects that tunnel into the stems and leaves of the gopher plant. They can cause wilting, yellowing, and stunted growth of the plant. The most common types of borers that infest gopher plants are stem borers and leaf miners. Stem borers lay their eggs in the stems of the plant, while leaf miners lay their eggs on the leaves of the plant.

If you notice holes in the stems or leaves of your gopher plant or see a sawdust-like substance around the base of the plant, it is likely that your plant has been infested with borers.

Getting Rid of Borers on Gopher Plants

Getting rid of borers on gopher plants can be a challenging task. Here are several methods you can try:

1. Pruning

One effective way to get rid of borers on your gopher plant is by pruning affected parts of the plant. Use sharp pruning shears to cut off any infested stems or leaves. Be sure to sterilize your pruning shears with rubbing alcohol between cuts to prevent spreading the infestation.

2. Insecticides

Another effective method for getting rid of borers on gopher plants is by using insecticides. There are several insecticides that can be used to control borers, including pyrethroids, neonicotinoids, and organophosphates. Be sure to read the label carefully and follow the instructions for use.

3. Beneficial Insects

You can also consider introducing beneficial insects to your garden to control the borer population. Ladybugs, lacewings, and parasitic wasps are all natural predators of borers and can help keep their population in check.

4. Cultural Practices

Finally, you can prevent future infestations by practicing good cultural practices. Keep your gopher plant healthy by providing it with adequate water and fertilization. Avoid over-fertilizing, as this can attract borers. Additionally, avoid pruning your gopher plant during the summer months when borers are most active.
