Worm castings plus live worms are the best – and easiest
– fertilizer for container gardens. Worms
continually aerate your soil as well as adding more nutrients. As
you’ll notice, you need only 25 worms for two window boxes, so for a very
small added expense you start your plants out twice as well.
Worm casting will fertilize immediately while your worms get organized.
You won’t need to add any additional fertilizer until next spring! In warmer
climates, worms will last as long as four years.
castings and worms for all your containers just takes a few moments:
Each of our 36-inch window boxes is 2,304 cubic inches, so an
order is 4,608 cubic inches.
Just multiply the length, width and height of a container all
together, and compare them to 4,608 for the popular give pounds per every two
Example: a container 14 inches long, 14 inches
wide and 18 inches deep has 3,528 cubic inches.
So you’ll need about ¾ of an order for each planter that size.
If you don’t want to estimate, divide 4,608 by your cubic inches –
the result will be how many bags of our worm castings you’ll need.
Figuring the number
of worms needed for all your containers is just one more easy step:
Just calculate your cubic inches as you do for worm castings.
Use your cubic inches, as you did for worm castings. So your container
that is 14” x 14” x18” will ideally get ¾ of an order, or at least 16
worms. A few more or a few less worms will be fine, too.
Or be a great friend or neighbor and share your extras!
If your ratio was 1.5, you’d need about 36 worms.
Just use the 25 worms in your Hooks and Lattice order as your reference
point when figuring the number of worms.
