Our take on the Groundwork 40 lb. 4,000 12-12-12 All-Purpose Fertilizer

Groundwork's all-purpose fertilizer is a 40 lb. bag of balanced 12-12-12 granular feed, meaning 12% each of nitrogen, phosphorus and potassium. The even ratio suits vegetable gardens, trees, shrubs and flowers, and it can be applied year-round as needed. One bag covers up to 4,000 sq. ft., so it fits large beds and lawns better than small garden boxes. Against single-nutrient or high-nitrogen lawn feeds, the balanced blend is more versatile but less targeted; against premium slow-release brands, it is a plain granular product you apply and water in.

Questions and answers

What do the three numbers 12-12-12 mean?
They are the percentages of nitrogen, phosphorus and potassium by weight. Each is 12%, so the blend is balanced rather than aimed at one plant need.
How much area does one bag cover?
Up to 4,000 sq. ft. at the label rate. Smaller gardens use proportionally less, so a single bag lasts several seasons.
Can I use it on vegetables I will eat?
Yes. It is labeled for vegetable gardens as well as trees, shrubs and flowers. Apply to the soil and water it in thoroughly.
When should I apply it?
It can be applied year-round as needed. Many gardeners feed at planting and again during the growing season.
Is it a slow-release fertilizer?
No. It is a standard granular all-purpose feed, so plan on reapplying through the season rather than relying on one application.
How do I apply it?
Spread the granules over the soil at the label rate, then water thoroughly so they dissolve into the root zone.
