How to Use Organic Plant Food & Insect Repellent


Organic plant food comes in two different forms: granular and liquid. Organic insect repellents are a slightly more complex topic, since organic gardening seeks to regard the garden as part of a larger ecosystem. Planting certain companion plants and/or luring beneficial insects to your garden (that dispose of harmful ones) is also considered "organic insect repellent." Floating row covers can insulate against sudden frost, but they can also shield vulnerable plants against insect encroachment as well.

Step 1

Read the suggested feeding instructions for your plants, either on the packages or by looking them up. Read the package of organic plant food as well. Determine between the two sets of instructions how much and when to feed.

Step 2

Dilute solutions of fish emulsion or any other high-nitrogen liquid plant food with water before feeding; excess nitrogen exposure can burn tender plant roots.

Step 3

Spray insecticidal soap on plants when you have identified insect problems. Do not spray preventively; only spray as needed.

Step 4

Plant companion plants that insect pests do not like, such as onions, garlic, chives and mint. Drive away insect pests with the power of strong, natural scent.

Step 5

Plant companion plants that beneficial insects do like, such as big, fragrant flowers. Attract beneficial insects such as ladybugs, lacewing flies and praying mantis so that they will eat insect pests.

Step 6

Pile dead leaves and other yard debris (such as twigs and grass clippings) near your garden. Make a good place for spiders to hide, build homes and wait for their insect pest dinner to be delivered to their doorstep.

Step 7

Use floating row covers to protect plants against flying insects, while still allowing sunlight and air to filter in to your plants. Pound floating row hoops into the ground to raise the row covers off the tops of the plants if they are fragile.

Tips and Warnings

  • Floating row covers can create a problem as well, particularly if you have insects living in your soil. Make sure all insect pests on the plants have been killed or evicted before erecting floating row covers. Otherwise, you will be sheltering the pests from their predators and providing them an all-you-can-eat buffet.
