Cup plant, also known as Silphium perfoliatum, is a beautiful and beneficial plant that can bring life to any garden. However, slaters are known to feed on the leaves of this plant, causing damage and reducing its overall health. If you’re struggling with a slater infestation on your cup plant, don’t worry – there are several natural methods you can use to get rid of them.
Identifying Slaters
Before we dive into how to get rid of slaters on cup plant, it’s important to know what they look like. Slaters are small, grayish-brown insects that measure up to 1 cm in length. They have oval-shaped bodies and six legs, and they move quickly across plants and soil.
Natural Methods for Getting Rid of Slaters
1. Handpicking
One of the easiest ways to get rid of slaters on cup plant is by handpicking them off the leaves and stems. This method is time-consuming but effective, especially if you only have a few plants to tend to. Make sure to wear gloves and discard the slaters away from your garden to prevent them from returning.
2. Diatomaceous Earth
Diatomaceous earth is a natural powder made from fossilized diatoms that can be used to control slaters. Sprinkle a thin layer of diatomaceous earth around the base of your cup plant, making sure to cover the soil and any cracks or crevices where slaters may be hiding. The powder will dehydrate the insects, causing them to die.
3. Beer Traps
Beer traps are an effective way of attracting and trapping slaters. To make a beer trap, bury a small container such as a tuna can in the soil near your cup plant and fill it with beer. The slaters will be attracted to the smell and drown in the liquid.
4. Beneficial Insects
Introducing beneficial insects such as ground beetles and centipedes into your garden can help control slater populations. These insects prey on slaters and other garden pests, keeping their numbers in check. You can purchase beneficial insects online or at your local garden center.
Prevention Tips
Preventing a slater infestation on your cup plant is always better than having to deal with one. Here are some prevention tips to keep in mind:
-
Avoid overwatering your cup plant, as slaters thrive in moist environments.
-
Keep your garden clean and free of debris, as this can provide hiding places for slaters.
-
Use organic fertilizers instead of chemical ones, as slaters are attracted to the nitrogen in chemical fertilizers.
-
Use mulch around the base of your cup plant to discourage slaters from laying their eggs in the soil.
