From your favorite little worm farm--Love flourishing healthy plants?  So do we!  Give your plants the best chance at optimal growth by using our Work Hard Worms' worm castings, aka vermicompost, aka worm poop, mixed with your soil.  For the plant world, these castings are like vitamins and yogurt in one product as they contain the minerals plants need along with doses of healthy soil bacteria.  You will not have need of mixing up bright blue fertilizer ever again.  (Read all about how organic fertilizers are far superior to manufactured fertilizers in our Education/FAQ page.)

(**ask for new customer discount on 150-lbs plus)   

Instructions for suggested mixing the vermicompost will be included with your order.

For this product, you will receive almost 100% worm castings.   What does the "almost 100%" claim mean?  We harvest our worm bins using a 1/8" screener without diluting them; however, the screening process does allow occasional 1/8" size bits of wood chips through.  However, the "other stuff" that gets through is organic compost, so, no worries, it will not harm your plants. 

Measure your pot and find out how much soil you will need with the calculator below:  

**Please note:  

Quantities using the below calculator will show you total volume of soil needed to fill a certain pot size.  For best results, we recommend that you mix the vermicompost with another soil base at a 70% base/30% vermicompost mix.)

We regularly monitor and maintain the moisture content in our castings.  For more information on this process, visit our Education/Frequetly Asked Questions Page here.
