How to Control Pests

There are a number of ways to control pests on bougainvillea. The best approach will vary depending on the type of pest, the severity of the infestation, and the preferences of the gardener.

Hand-picking insects

One of the simplest ways to control pests on bougainvillea is to hand-pick them. This is a good option for small infestations of aphids, mealybugs, scale insects, and whiteflies. To hand-pick insects, simply inspect the plant regularly and remove any pests that you see.

Using insecticidal soap or horticultural oil

Insecticidal soap and horticultural oil are both effective at killing a variety of pests on bougainvillea. Insecticidal soap is a mild soap that is designed to suffocate insects. Horticultural oil is a type of oil that coats the insects and prevents them from breathing.

To use insecticidal soap or horticultural oil, simply spray the plant according to the package directions. Be sure to read the label carefully and follow all safety precautions.

Applying a systemic insecticide

Systemic insecticides are absorbed by the plant and then distributed throughout the plant’s tissues. This makes them effective at killing pests that feed on the leaves, stems, and roots of the plant.

To apply a systemic insecticide, simply mix the insecticide according to the package directions and then water the plant with the solution. Be sure to read the label carefully and follow all safety precautions.

Releasing beneficial insects

Beneficial insects are predators of pests and can help to control their populations. Some of the most common beneficial insects that are used to control pests on bougainvillea include:

• Ladybugs
• Lacewings
• Praying mantises
• Parasitic wasps

To release beneficial insects, simply purchase them from a garden center or online retailer and then release them near the infested plant. Be sure to read the label carefully and follow all safety precautions.

Pruning infested branches

If a bougainvillea plant is heavily infested with pests, it may be necessary to prune the infested branches. This will help to reduce the number of pests on the plant and prevent them from spreading to other plants.

To prune infested branches, simply cut them off at the base of the plant. Be sure to wear gloves to protect your hands from the sap.

Applying mulch around the base of the plant

Placing mulch around the base of the bougainvillea plant can help to deter pests. Mulch helps to create a barrier between the plant and the ground, which makes it more difficult for pests to reach the plant.

To apply mulch around the base of the plant, simply spread a layer of mulch around the plant, starting about 6 inches from the stem. Be sure to keep the mulch away from the stem of the plant.

Preventing Pest Infestation

The best way to prevent pests from infesting bougainvillea is to take steps to protect the plant. Here are a few tips for preventing pest infestation:

• Plant bougainvillea in a location that is protected from pests. This could include planting it in a sunny spot with good air circulation, or planting it under a tree or other structure that will provide some shelter from the wind.
• Water the plant regularly and fertilize it according to the package directions. This will help to keep the plant healthy and strong, which makes it less likely to be susceptible to pests.
• Prune the plant regularly to remove dead or diseased branches. This will help to keep the plant healthy and free of pests.
• Inspect the plant regularly for signs of pests. This will allow you to catch any infestations early on, when they are easier to control.
