TAGRO Potting Soil

House plants in a slump? The root of the problem could be your soil. Try TAGRO Potting Soil especially designed for container-grown plants.

TAGRO Potting Soil is a nutrient-rich blend of 20 percent Tacoma biosolids, 20 percent high-quality maple sawdust and 60 percent clean, aged bark. TAGRO Potting Soil is safe for indoor and outdoor use, and works in both flower and vegetable gardens. It is perfect for outdoor raised planting beds. 

TAGRO Potting Soil also contains some small stone and some larger pieces of aged black bark which aids in porosity, structure and overall soil tilth.

Using TAGRO Potting Soil

Use TAGRO Potting Soil in indoor and outdoor container gardens, in the greenhouse, or in pots of any size.


TAGRO Potting Soil is a “soil-less” mixture of aged, screened, black-fir bark; sawdust and Tacoma’s Class A biosolids. It’s a high quality, nutrient-rich potting soil without traditional ingredients like peat moss, vermiculite, perlite, coconut fiber, pumice, compost, sand and chemical “tiny time pills.”

Benefits of TAGRO Potting Soil

It contains a balance of readily available and slow-release plant nutrients. TAGRO Potting Soil has a very high nutrient content, but won’t burn sensitive plant tissues.

  • The structure is perfect for potted plants to develop strong root systems, which is vital to the performance of containerized plants.

  • TAGRO Potting Soil has excellent water-holding capacity and necessary nutrients.

  • Eliminates the need for additional fertilizing for several months.  

Tested at Washington State University’s Puyallup Cooperative Extension, TAGRO Potting Soil outperformed traditional potting mixes.

With no odd white specks, TAGRO Potting Soil retains a natural, freshly bought look for many months.  



TAGRO Potting Soil is best with containers of 8 inches in diameter and larger. Carefully water plants in smaller containers. Seeds sprout in it very well, but again, water carefully. Because the potting soil tends to dry out in small pots (eight inches in diameter or less), make sure to check it carefully and apply water when necessary.



All the things you want in a container garden, you also need in a raised bed. Because of its excellent drainage and nutrient-rich properties, TAGRO Potting Soil is perfect for raised beds. And, it has a convenient “self-mulching” feature. Since TAGRO Potting Soil is made of a screened-bark material, its loose structure essentially self-mulches to assure even temperatures and water content in your planted bed. This is especially noticeable during the dry summer months when it provides superior water conservation.

Raise a bed eight to ten inches or more using TAGRO Potting Soil, and you are ready to plant whatever you want. Or, for a tall bed (three feet or more), you could use a sandy mixture in the bottom third, and TAGRO Potting Soil in the remainder of the bed.

TAGRO Potting Soil is economical for densely planted urban beds, planters or larger containers. It meets and exceeds standards for use on any type of vegetable or fruit.



Use TAGRO Mix for new or existing lawns and as a soil amendment for flower and garden beds.


General Tips

  • As with other gardening products, wash your hands after using TAGRO.
  • As with any product containing nitrogen, do not introduce TAGRO products into any body of water. Use all soil amendments conservatively to help protect groundwater from nitrates. Please be especially cautious when using it in low valleys, and keep it away from water runoff areas.

TAGRO Topsoil   

TAGRO Topsoil is a four-way mix ideal for refreshing gardens and flower beds. It is an intermediary between native nutrient-barren soils and nutrient-rich manufactured soils such as TAGRO Potting Soil. TAGRO Topsoil adds organic matter and nutrients without decreasing porosity. TAGRO Topsoil meets the Type IV topsoil specifications of the Washington State Department of Transportation and the City of Tacoma.  


Aged Black Bark

Aged Black Bark serves as a low-nutrient ground cover similar to traditional beauty bark – except that it’s black. TAGRO’s Aged Black Bark is ground finer than traditional beauty bark making it more visually pleasing to most gardeners.

Aged Black Bark contains no TAGRO biosolids.

Aged Black Bark will add both structure and organic matter to soils, improving the rooting of plants. The best uses for Aged Black Bark are:

  • As a ground cover and weed barrier in flower beds and gardens
  • Mixed into soil to increase the amount of organic matter
  • Added to older beds that have sunk over time

As with any surface layer that is high in organic content, Aged Black Bark helps keep moisture in the soil and moderates temperature swings. TAGRO’s Aged Black Bark captures the sun’s rays and helps plant roots warm up a few degrees earlier, which helps in early planting of both vegetables and flowers.

TAGRO’s Aged Black Bark is a weed-free mixture that helps keep weeds out of your garden and flower beds. If weeds sprout from seeds that may have blown in, the loose structure of the product makes weeding easier.
