Organic Fertilizer


A natural substance derived from plant, animal, or mineral matter that is added to soil in order to make it more fertile.

Things you need to know

In addition to fertilizing your plants, organic fertilizers feed the soil, improving its condition over time. Their nutrients are also released more slowly, giving plants a steady source of nutrition over longer time period. Using only synthetic chemical fertilizers causes the soil's structure and water-bearing capacity to deteriorate.

Also known as

Mulch, Compost, Manure

Cost Considerations

Due to the fact that organic fertilizers are less concentrated than synthetic fertilizers, their cost per square footage will generally be higher. However, this cost may eventually be outweighed since organic fertilizers improve the soil over time.

Costs vary greatly by region (and even by zip code). To get free estimates from local contractors, please indicate yours.
