Basic Worm Selection Criteria

Basic Worm Selection Criteria

There are around one million species of worm that inhabit the earth. These different worm species are divided into three categories: the compost worm, the earthworker worm, and the root dwelling worm. Not all worms will be suitable for the Garden Tower® 2 system. 

We recommend these worm species for the Garden Tower® 2 system:

  • Red Wigglers -- popular compost worms known for their voracious appetites
  • Nightcrawlers and other garden worms -- these worms will dwell and tunnel deeper into the soil than most composting worms 

Worms will reproduce quickly in the Garden Tower® 2 system, so you only need to add a small number of them to it. In many climates, worms can even survive over winter without additional protection in a Garden Tower® 2 vertical planting system. 

Where to Buy Worms

Where to Buy Worms

Worms can be purchased at almost any local store situated near a body of water, such as a lake or stream. Bait shops usually serve as the go-to store for worms. Sporting goods chains and even department stores and some gas stations stock red wigglers and nightcrawlers for bait. There are numerous mail-order worm sources and ample information on vermiculture available online as well.
