As a soil amendment, topdressing can improve soil biology by adding organic matter and the beneficial microorganisms of compost. Soil structure and drainage can be modified by topdressing with sand or other corrective materials. Topdressing regularly can smooth out bumps caused by worm castings and encourages a dense, lush lawn.
Topdressing reduces lawn stresses, helps keep thatch under control and acts as a long-term natural fertilizer. Adding organic matter to a lawn by topdressing with compost is the most beneficial cultural practice lawn care has to offer.
The Best Material for Topdressing should be dark and rich and made with a variety of organic material with few fillers like sawdust or loam. In some cases, compost is blended with soil or sand to make it more affordable, just be sure the added soil is compatible with the soil of the lawn.
We always recommend one time every year on Spring or Fall.
铺肥料土作为土壤改良剂，可以通过增加有机质和有益的微生物来改善土壤生物学。土壤结构和排水可采用砂或其他改良材料进行改良。定期的铺肥料土可以抚平蠕虫铸件引起的突起，并鼓励浓密茂盛的草坪。
铺肥料土减少草坪的压力，有助于保持杂草控制，作为一种长期的天然肥料。将有机物添加到草坪上，用肥料土追肥是草坪养护最有益的文化实践。
铺肥料土的最佳材料应是深色、丰富的，用各种有机材料制成，不含锯末或壤土等填料。在某些情况下，堆肥与土壤或沙子混合，以使其更容易负担，只是要确保添加的土壤与草坪的土壤相容。
我们总是建议在每年春季或者秋季做一次。
