Top tips for feeding cooked vegetables to worms

Here are my top tips for safely feeding cooked vegetables to your worms. These tips will help to keep your worm bin in balance, prevent ants and flies and help the worms to digest the vegetables quickly.

1. Add small amounts of cooked vegetables at a time

When adding cooked vegetables to your worm bin it is important to start by adding small amounts at a time. If you have a small worm farm, start with a small handful of cooked vegetables and see how long it takes for your worms to break them down.

After they have broken down the first amount, you can add more. Adding too many cooked vegetables at a time can add too much water to the worm farm and attract ants. You want to add just enough so that the worms can break them down within a week.

Larger worm bins can break down large amounts of cooked vegetables when they are working well. Remember to start with small amounts and layer them thinly on the surface. This will give the worms more room to move and more surface area to break the vegetables down quicker.

2. Avoid adding cooked vegetables with added salt

Avoid adding cooked vegetables to worm bins that have lots of added salt. Salt can harm the worm and end up in the worm castings. This salt can damage your soil if you mix it through. It is always best to avoid adding any extra salt to your worm bin to keep it healthy.

3. Cut cooked vegetables into small pieces

To help worms to break down cooked vegetables quicker it is important to cut them up into small pieces. Cut them up into pieces that are 1/3 of an inch or less to give the worms more surface area to eat from.

This will also increase the amount of soil bacteria that start to break down the vegetables. The worms will eat the soil bacteria as well as the vegetables breaking it down even quicker.

Helping worms to break down the cooked vegetables fast will mean that you can make worm castings quicker and have them ready sooner for your garden.

4. Cover the cooked vegetables with dry, brown materials

After adding cooked vegetables to your worm bin, cover them with some dry, brown material. This could be dry fall leaves, straw, tree mulch, hay or sugar cane mulch. This will help to absorb the extra water from the vegetables to stop your worm farm from becoming too wet.

This layer will also help to prevent ants and flies from coming into your worm bin. Sweet, cooked vegetables including carrots and squash can attract ants so remember to cover them every time. The worms will eventually eat the brown material too, turning them into worm castings.

5. Wait for cooked vegetables to cool before adding them

Always wait for cooked vegetables to cool completely before putting them in your worm bin. Allow them to cool on your kitchen bench until they reach room temperature. They can then then be added to your worm farm.

Adding hot, cooked vegetables to worm bins can harm your worms. They are sensitive to heat and even can be burnt by the hot vegetables. Hot vegetables can also kill soil bacteria in the worm farm so always make sure they are at room temperature first.

6. Use a tight fitting lid for your worm bin

Always make sure you have a tight fitting lid on your worm bin if you are adding cooked vegetables. Rats and mice love to eat cooked vegetables so keep them out with a good lid. Worm bins will usually come with a good lid which only has small holes to allow air movement.

Make sure the lid is sitting on the worm bin straight to block any gaps that could allow rats and mice to enter.

7. Cover with a worm blanket

Always cover the top of the worm bin contents including cooked vegetables with a worm blanket or an alternative. Worm blankets can be purchased to fit most worm bins or make one yourself. You can use recycled materials like cardboard, newspaper, old t-shirts, hessian or sheets to cover the surface of your worm bin.
