Tree and Shrub Care: Essential Weed Control Tips

Mulching For Weed Suppression

• Choose organic mulch, such as wood shredded bark, wood chips, or straw, as it gradually breaks down and adds nutrients to the soil.
• Apply a layer of mulch 2-4 inches deep around the base of trees and shrubs, leaving a small gap around the stem to prevent moisture buildup.
• Mulch acts as a physical barrier, blocking sunlight from reaching weed seeds and preventing their germination.
• Regularly replenish mulch as it decomposes to maintain an effective weed-suppressing layer.

Manual Weed Removal

• Wear gardening gloves to protect your hands while removing weeds.
• Use a handheld garden trowel or fork to loosen the soil around the weed's base, ensuring you remove the entire root system.
• Pull the weed gently and steadily, extracting the roots completely to prevent regrowth.
• Dispose of the pulled weeds properly to prevent reseeding or spreading.

Chemical Weed Control

• Select a herbicide formulated for woody plants and labelled safe for use around trees and shrubs.
• Read and follow the manufacturer's instructions carefully, paying attention to dosage, application timing, and safety precautions.
• Apply herbicides directly to the weed foliage or use a targeted spot treatment method to minimize the impact on desirable plants.
• Avoid spraying on windy days to prevent drift and unintended damage to nearby trees, shrubs, or other vegetation.

Regular Monitoring and Maintenance

• Regularly inspect your landscape for any signs of weed growth, especially around trees and shrubs.
• Address weed growth promptly to prevent them from establishing deep root systems and spreading further.
• Stay vigilant, particularly after rainfall or irrigation, as moisture can encourage weed germination and growth.
• Maintain a healthy tree and shrub environment through proper watering, fertilization, and pruning, as healthy plants are more resistant to weed competition.

Preventive Measures

• Use weed barrier fabrics or geotextiles around trees and shrubs to create a physical barrier against weed emergence.
• Practice spacing between trees and shrubs to limit weed growth and facilitate airflow.
• Avoid overwatering, as excessive moisture can promote weed growth.
• Consider applying pre-emergent herbicides in early spring to prevent weed seeds from germinating.
