Myth 3: Organic Pesticides Are Always Safe
While organic pesticides are derived from natural sources and considered safer than synthetic alternatives, they are not without risks. Some organic pesticides can still be harmful to humans, beneficial insects, and the environment if misused. For example, rotenone, an organic insecticide, is highly toxic to aquatic life and dangerous to other wildlife if not carefully applied.
Gardeners should treat organic pesticides with the same caution as chemical ones, adhering strictly to application guidelines. It’s often more effective to use non-chemical pest management methods, such as introducing beneficial insects that prey on harmful pests or using barriers to prevent pests from reaching plants.
Myth 4: Pruning Back Severely Promotes Growth
Severe pruning is often believed to invigorate plants, encouraging new growth and vitality. While pruning is necessary to remove dead or diseased branches and shape plants, excessive pruning can stress the plant, reducing blooms and fruits. It can also make plants more susceptible to diseases and pests by exposing more plant tissue.
The key to effective pruning is moderation and timing. Many plants should be pruning during the dormant season, and only the necessary branches should be cut back. Always use sharp, clean pruning tools to make clean cuts that heal quickly.
Myth 5: Planting Native Species Requires No Maintenance
Native plants are adapted to their local environment and, thus, generally require less maintenance than non-natives. However, this does not mean they require no maintenance at all. Native plants still need proper siting in the appropriate sun exposure and soil type, regular weeding, and, in some cases, pruning and pest management.
Using native plants in your garden can reduce the need for water and fertilizer and increase the garden’s overall resilience to local conditions. Nevertheless, they still benefit from occasional check-ups and care to ensure they thrive.
