21 Ways to Keep Bugs Off Your Hemp Plants Without Pesticides

There are few things worse for a gardener than tending to your garden for hours on end, only to have pests come in and destroy your crop. I know I’ve experienced it: watching the perfect tomato ripen on the plant, only to come home one day and find it has been destroyed by bugs. We don’t want to put pesticides on the foods we’re going to be eating, so it may seem like there are no options.

If you’re tired of losing your crops to insects, such as aphids and potato beetles, read on to find out natural ways to keep bugs off of your plants without pesticides. These ways are safe and involve products you may already have in your house or plants you can grow, increasing the bounty and beauty of your garden. We’ll cover 21 different ways that you can implement this season to keep your plants healthy and help produce a plentiful crop.

Why is the Natural Way Important?

When bugs come and feed on your plants, they can do a great deal of damage in a short amount of time. There are dozens of different products on the market that claim to help keep bugs off of your plants, but how safe are they? Unfortunately, pesticides can be very dangerous and have been linked to health conditions such as ALS or Lou Gehrig’s disease. The good news is that, with a little planning and some dedicated garden space, you can help keep pests away from your plants naturally.

The first 3 tips are natural products you can sprinkle on the ground.

#1. Diatomaceous Earth

A safe first step to keep pests away from your plants is to sprinkle a layer of food-grade diatomaceous earth around the garden.

In addition to making a barrier of it, put a small layer around vegetables or fruits that touch the ground, such as watermelon and squash.

You can also sprinkle a fine layer around the garden to keep crawling insects, as well as larger pests away, such as snakes and raccoons.

#3. Fish Fertilizer

Another product that can help keep pests away from your plants is fish fertilizer. The added advantage of this is that it will also fertilize your plants safely. One suggestion is to mix a gallon of water with 2 tablespoons of liquid fish fertilizer and spray it on the ground.

As crazy as it might seem, adding a little dish soap to a bottle of water can be a highly effective way to keep bugs away. Add the soap after you’ve filled a spray bottle with water and mix it well.

You read that right: beer. It’s a great way to keep pests away from your plants and is not harmful to humans. Sprinkle it around and on vegetable and fruit plants to help keep insects away. They’ll be repelled by the smell and the taste of it.

In addition to alternating bush beans and potatoes, you can further protect the plants by planting petunias around beans and potatoes. This will add a splash of color to your garden, and they help keep insects like the Colorado potato beetle away.

Catnip is a relative of the mint family, and it makes an excellent companion plant. You can plant it around plants like zucchinis and cucumbers to help keep cucumber beetles away.

#19. Rosemary

Rosemary can be interspersed around a great many plants, and it is incredibly effective at keeping certain bugs away, not to mention it is a lovely aromatic herb that goes well in many dishes.

#20. Attract Birds

While you might be worried about birds eating your produce, they are an excellent resident to have in your garden — plus they look great when you’re relaxing on your patio. Keep a bird feeder and bird bath in the garden to lure birds; if you begin in the fall, they’ll already be there when spring rolls around. Depending on your location, you might also consider guinea fowl, which will eat a variety of bugs, including ticks, and they don’t tend to bother your plants.

#21. Attract Lady Bugs

You can attract ladybugs by growing plants that they like, or you can actually order ladybugs to be delivered to your house. Why add more bugs to the garden? These friendly insects won’t hurt your plants, but they will eat insects such as aphids, which can do a great deal of damage to your plants.
