Q. How do I look after my worms during hot weather?
A. Your worms are living creatures, treat them as you would your family pets.
There are some simple steps you can take to ensure your worms can cope with the summer heat & continue to work for you recycling that waste & producing the good stuff for your garden.
Make sure your worm farm is located in the coolest possible spot.
Don’t allow any sun to shine on it at all. Even morning sun for a short amount of time can be very hot. Worm farms made from black plastic can heat up extremely quickly.
Also be mindful that hot air blowing around the worm farm can also heat it.
- Limit feeding.
As food waste generates heat as it’s breaking down, be very careful not to have a build-up of uneaten waste. On the hot days, we also recommend reducing the amount you normally feed. Even not putting in any food is fine. Don’t worry the worms will not starve.
- Keep them cool.
Have ready in the freezer a collection of ice packs. Solid ice blocks, as large as possible are best. Ice cubes are too small & defrost too quickly. You can use frozen 600ml water or cooldrink bottles, esky cool bricks, ice packs or takeaway containers full of ice. Keep the ice in their containers & place under the blanket in the worm farm.
On hot days, place a couple of ice packs in the worm farm first thing in the morning & swap them over as they defrost throughout the day.
Even if you are not sure if it’s going to get very hot that day, it won’t do any harm putting the ice packs in. Think of it as a good insurance policy to safe guard your worms.
The aim is to create a COOL environment inside the worm farm.
Make sure the blanket & their bedding is moist at all times. But do be careful when watering, if the bedding has already got warm/hot then it will heat the water & potentially boil your worms.
If the bedding has already got hot, put in the ice packs rather than watering. Remember you want to create COOL.
- Prop the lid open.
By leaving the lid slightly ajar or propped open creates air flow & allows any hot air to escape.
- Put them in the garden.
If you are struggling with finding a good location or keeping them cool, you can place the trays of the worm farm with the worms out into the garden. Place them in a reticulated area, so they are getting watered. You can continue to feed the worms in the trays as per usual. If it gets too hot, the worms can move down into the soil where it is cool. They will come back up to feed when it’s suitable.
When the weather is cooler, you can collect the trays along with the worms & reassemble it.
