这么薄薄铺几粒就是刚铺上好看吧,明年也许都找不见了。不能小袋小袋买,去专门卖石子的地方订上几个yard,厚厚地铺上才起作用。
今天又铺了3包。15-20包估计够了

Why People Use Marble Rocks Under Trees
Aesthetic appeal: Clean, bright look that contrasts well with dark soil and tree bark.
Weed control: Helps reduce weed growth, especially with landscape fabric underneath.
Low maintenance: Doesn’t break down like mulch.
Improves drainage: Prevents water from pooling at the base of the tree.

Potential Concerns
Heat stress
Light-colored rocks (like white marble) reflect sunlight and can raise the temperature around tree roots and trunk, potentially stressing the tree—especially in hot climates.
Soil compaction & root stress
Heavy rocks don’t insulate or breathe like organic mulch, which could limit air and moisture movement into the soil.
Nutrient loss
Unlike mulch, rocks don’t decompose, so they don’t add nutrients to the soil.
Trunk damage risk
Avoid piling rocks against the tree trunk. Leave a few inches of clear space to prevent moisture buildup and rot.

Best Practices for Using Marble Rocks Under a Tree
Lay landscape fabric on the soil first (optional but helps suppress weeds).
Use 1–2 inches of rock, not a thick layer.
Leave a 6–12 inch gap between the tree trunk and the start of the rock layer.
Water deeply as needed, since the rocks may slightly reduce soil moisture retention.
