One great advantage of having a vertical garden is the limited exposure to soil-dwelling pests. Your vertical garden has less direct contact to the ground, after all. But don’t get lulled into a false sense of security when it comes to pest control – it will still be an issue.
Any insect or other critter that could infest your traditional horizontal garden can still gain access to your vertical garden, particularly if you’re using an in-ground plot for planting. Keep in mind that many notorious garden pests begin to fly at later life stages. They’re happy to leave eggs on your eggplant or helping the kids to gorge on your green beans.
To limit the potential destruction by garden pests, you’ll want to take many of the same measures you would to limit disease – clear yard debris from your planting areas, make sure to rotate crops, and use well-turned soil that’s been fortified with clean compost.
Still, you might find pests worm their way into your vertical garden.
Two vertical garden pests
- Squash bug: Squash bugs are gray or brown and prefer pumpkins and squash, typically toward the end of the growing season. Rotating crops and cleaning fall debris will help discourage them come planting season. During growing season, check the undersides of leaves for egg masses and destroy any that you find.
- Cucumber beetle: Usually black or yellow spotted or striped, these critters love your cucumbers. Larvae go after the roots while the adults gnaw on leaves, so your attack should be two-pronged as well. Products such as Safer®Brand 3-in-1 Garden Spray can help discourage both from overtaking your garden in either stage. A floating row cover will help protect from beetles in their flying stage.
