If you’re an avid gardener, chances are you’ve encountered spider mites at some point. The tiny arachnids are notorious for infesting a variety of plants, both indoor and out. However, outdoor plants are particularly susceptible to these pests due to their exposure to weather conditions and other environmental factors. In this article, you will learn how to spot and control spider mites on your outdoor plants.
What are Spider Mites?
Spider mites are arachnids that are commonly found on trees, shrubs, and ornamental plants. They are very small, typically measuring around 1/20 inch in length. Spider mites are also invisible to the naked eye, so it can be challenging to spot them at first glance. These pests feed on the sap from the leaves of plants, causing them to appear yellow, pale, or spotted, and eventually leading to their death.
Spotting Spider Mite Infestations
The first sign of a spider mite infestation is usually spotted leaves. Upon closer inspection, you may notice tiny webs that cover the undersides of the leaves. These webs are created by the spider mites, who spin them to protect themselves and their eggs. With a magnifying glass, you may spot the spider mites themselves, which are usually reddish or yellowish-brown in color.
Control Measures for Spider Mites
If left unchecked, spider mites can quickly infest your entire garden. Fortunately, there are several methods you can use to control these pests.
1. Increase Humidity
Spider mites thrive in dry conditions, so increasing the humidity in the area can help to control their population. You can use a humidifier or simply spray your plants with water regularly.
2. Prune Infested Leaves
Remove any leaves that have visible webbing or damage from spider mites. This will help to prevent any further spread of the pests.
3. Use a Homemade Soap Spray
One effective way to control spider mites is to use a homemade soap spray. Simply mix one tablespoon of dish soap in a gallon of water and spray the solution onto the infested plants. The soap will kill the mites but won’t harm the plant itself.
4. Use Insecticidal Soap
Another effective control measure is to use insecticidal soap. This type of soap is specifically designed to kill spider mites and other garden pests. Follow the instructions on the product label when applying.
5. Use Predatory Mites
In some cases, you may be able to introduce predatory mites to your garden to control spider mites. These mites feed on the spider mites and can help to reduce their population. Consult with a professional or an experienced gardener before introducing any new insect species to your garden.
In conclusion, spider mites can be a nuisance for any gardener. However, by regularly inspecting your outdoor plants, pruning infested leaves, and using effective control measures, you can keep these pests under control and maintain a healthy garden.
