All Worm Farming

Self-sustainability is a goal we should all work towards in some capacity. In regards to this aim for self-sufficiency, seasonal changes can often be overlooked when overseeing your worm farm. Building an in ground worm bin can help rectify this oversight.

Why Build an In Ground Worm Bin

Like I said - seasons change. While easy to ignore because they are so small, a successful worm farm is reliant on the care of your worms. This means maintaining the worm bins, keeping ideal temperatures, and making sure they get food they like to eat.

In ground worm bins are wonderful homes for worms to help them have healthy moisture levels and stay warm - even during colder months.

Worms prefer temperatures warmer than 10°C (50°F) and worm farms often face challenges during the colder months. During these times, households continue producing the same quantity of veggie scraps, but worms consume less.

Underground temperatures tend to be much warmer than surface temperatures, maintaining around 12°C (53.6°F) to 15°C (59°F) throughout the year. When combined with using more than one in ground worm bin to keep on rotation, you considerably lower the risk of overfeeding the worms and harming them.

How to Build an In Ground Worm Bin

Items You Need

  • (2-3) 20 Gallon Bucket
  • A Drill
  • 10mm drill bit
  • 1/8 drill bit

Yes, it’s that simple.

Instructions

  • Drill the Bucket:
    • The first thing we’re going to do is take each bucket and, using the 10mm drill bit, drill holes all around the bucket. We’re also going to drill 10 to 12 holes around the bottom of each bucket for drainage.
    • Using a 1/8 drill bit, drill holes just under the rim of the top of the bucket. We need to do this to allow the worms to “breathe” without letting in mice and other critters we don’t want in.
  • Plant the Buckets:
    • After you have determined where you want to place your buckets, it’s time to plant them. Dig a hole slightly bigger than the bucket so it’s easier to take in and out of the ground. Then, just plant the bucket.
    • To keep the bucket in place, fill back the edges of the bucket with the dirt you just dug out.
    • Tip: Ideal placement is near the center of a patch of your garden, such as the vegetable garden, in order to help them flourish without much obstacle.
    • Keep your bucket away from any areas that overflow with water. You don’t want to flood your worms.
  • Plant the Worms:
    • Once the bucket is in place, it’s time to make this a habitable home for your worms. Start with creating bedding for them with scraps of cardboard or other compostable material, such as egg cartons.
    • After the bed has been made, add your worms! You’ll need to split about 2-5 pounds of worms between the buckets. You can purchase red wiggler worms from us to get started.
    • Start feeding your worms. If you aren’t sure what to feed them, refer to this article about what worms eat

You’ve done it! You’ve started your worm farm with an in ground system that will help them stay warmer year round. During the winter months, you may find it helpful to insulate your worm bins using straw or even a potato sack.
