Micro bark is a popular organic material used in gardening and landscaping. It offers a refined aesthetic and practical benefits for various outdoor spaces. As a type of mulch, it helps maintain soil health and contributes to a tidy appearance.
Understanding Micro Bark
Micro bark is a finely textured ground cover derived from the outer layer of trees, typically fir or pine. It has a small, consistent particle size, often double-screened for uniformity. This processing gives it a smooth, polished appearance, distinguishing it from coarser shredded bark. Its small size allows for an even spread and a refined finish in garden beds.
Key Uses of Micro Bark
Micro bark is widely used as a decorative ground cover, enhancing the visual appeal of flower beds, ornamental gardens, and around trees and shrubs. Its fine texture makes it suitable for creating pathways and walkways, providing a softer surface than gravel. It can also be applied in planter boxes, driveways, pet runs, and play areas.
Advantages of Micro Bark in Landscaping
A layer of micro bark effectively suppresses weed growth by blocking sunlight, which prevents weed seeds from germinating. This reduces manual weeding and helps plants thrive without competition for nutrients. Micro bark also conserves soil moisture by reducing evaporation, which means less frequent watering is needed, especially during warmer periods.
It helps regulate soil temperature, insulating plant roots from extreme heat in summer and cold in winter. This creates a more stable environment for root systems, promoting healthier plant growth. As it decomposes, micro bark enriches the soil with organic matter, improving soil structure and fertility. This decomposition also encourages beneficial microbial activity, contributing to overall soil health and reducing soil compaction.
Selecting and Applying Micro Bark
When choosing micro bark, consider the type of wood, as most varieties are derived from fir or pine, offering natural brown tones. Consistency in particle size, often achieved through double-screening, indicates a higher quality product and provides a more uniform appearance. For application, prepare the area by removing existing weeds and debris.
Spread the micro bark evenly across the desired area, aiming for a depth of 1 to 3 inches. Avoid piling bark directly against tree trunks or house foundations, leaving a few inches of space to ensure proper air circulation and prevent moisture buildup. Although micro bark helps suppress weeds, laying a permeable landscaping fabric underneath can provide an additional barrier, especially in areas with significant weed problems or high foot traffic. Regular replenishment may be needed as the bark slowly decomposes and integrates into the soil.
