By Kathryn Hatter ; Updated September 21, 2017

There are beneficial insects that a gardener cannot do without and there are harmful pests that can wreak untold havoc on fruits and vegetables. Sugar water is an interesting garden treatment has the benefit of attracting beneficial bees to pollinate the plants you have growing, and killing harmful nematodes that can damage many different plants with their feeding habits. Spray sugar water on your plants for positive results.

Measure and pour the sugar into the saucepan. Add the water and stir well to combine.

Place the saucepan onto the stove top and turn the burner to high. Heat the sugar water until it boils and then remove from the heat.

Allow the sugar water to cool to room temperature.

Pour the sugar water into the bucket and add 1 gallon of cool water. Stir well to combine. Pour some of the sugar water into the spray bottle.

Spray the sugar water onto vining plants that are beginning to blossom. Cucumbers, squash, melons, pumpkins and beans are all examples of plants that will benefit from spraying sugar water. Do not spray the blossoms themselves; spray the vines and the foliage to attract bees to the blossoms.

Watch the plants over the next day to observe whether the sugar water is attracting more bees to your garden. Apply the sugar water again after several days as long as there are new blossoms.

Spray the sugar water onto plants that are showing signs of a nematode infestation. Some common plants that frequently have nematode infestations are grapes, strawberries, raspberries, blackberries, beans, carrots, corn, cucumbers, lettuce, peas, peppers, tomatoes, squash, spinach and turnips. Plants that are turning yellow, wilting and not growing properly may have a nematode infestation.

Repeat the spraying process once or twice a week to attract bees and eradicate nematodes.
