5. Feed your plants (but not too much)
Fertilizers are important for any healthy garden, but opting for organic, low-nitrogen fertilizers will produce much better results, Pleasant says.
“In some soils when you’re using chemical fertilizers you can accidentally overdo it, and the plants produce this really lush, fast growth,” she explains. “That type of growth tends to attract insects that like to suck plant juices.”
To yield heartier, more reasonable growth, Pleasant suggests nourishing your soil with compost and adding an appropriate amount of low-dose, slow-release organic fertilizer as needed (some plants require more than others). For detailed fertilization tips for every crop in your garden, check out this guide from the Oregon State University Extension, or consult another extension service in your area.
“The bottom line is: Be careful never to apply too much nitrogen,” Pleasant suggests. “That can invite a problem.”
