We humans can rug up against whatever the season brings, but worm farms and compost bins are more exposed to the elements and vulnerable to cold temperatures, wind, and rain. Worms and other compost critters love warmth just like we do, so how do they deal with the wetter, chillier months?
The ideal temperature for worms is between 55 and 77 degrees Fahrenheit. Adding worms to bedding: When bedding is ready for the worms place the worms on top. They will disappear in a short time in the bedding.
Temperatures of about 60 to 80 degrees F. are ideal, but the worms will tolerate temperatures from 40 to 90 degrees F. You'll want the location convenient to your kitchen to make disposal quick and easy.
Worm activity slows down as the temperature drops. Below 40 degrees Fahrenheit, the worms will be at risk of succumbing to the cold. They will burrow toward the warmest part of the bin: the bottom and center. Any organic scraps that you add will increase the temperature slightly.
Worms cannot survive at temperatures above 35°C / 95°F.
Most composting worms are best kept in the 72°-80°F range. And the accepted conventional wisdom is that worms will be fine between 55°F and 90°F.
To keep your worms happy ensure that you provide them with the right amount of these 3 key elements: food, moisture and oxygen. 1. Feed them regularly or whenever they are running out of food. You will figure out how often you need to feed them by observing your worm farm (once or twice a week).
Want to give your worms a treat? Add ice. Place plain ice on top of the bedding or buried in the center of the bin. You can cool and feed the worms all at once by freezing scraps and water together.
Although worms can't survive freezing temperatures, they lay eggs that are encased and protected by very small cocoons. They can survive through winter to emerge as tiny baby worms, once temperatures warm up again.
Light — Worms will always quickly burrow away from sunlight as light is lethal to them. A worm farm needs a lid or cover to ensure that the conditions are dark.
Compost worms will live comfortably bedding temperatures (as opposed to air temperature) of around 16 – 27°C, give or take. Your worms will tolerate ranges of 4 – 32°C, however, they may become less productive at the temperature extremes.
Compost worms can adjust to a wide temperature range, however bed temperatures much over 30C worms become stressed and can die if the temperature remains high for sustained periods. Your worm farm has thermal mass making it slower than the surrounding air to heat up (but also slower to cool down).
Unfortunately, if the bin temperature gets too high, the composting worms will overheat, dry out and die. There are many things you can do to keep your worm population cool enough to survive. Placing the worm bin in the right location is the most important way to control the internal temperature.
During winter most worms stay in their burrows, prisoners below soil frozen hard as rock and topped by ice and snow. They are coiled into a slime-coated ball and go into a sleep-like state called estivation, which is similar to hibernation for bears. (The mucous, or slime, keeps the worms from drying out.)
Because earthworms breathe through their skin, it must be kept moist in order to work. Dry skin stops the diffusion process, effectively preventing earthworms from getting oxygen. That is why worms are so commonly spotted above ground when it is rainy and at night, when air is wetter.
To survive freezing cold temperatures, worms must burrow to an area below the frost line wherever they live. Night crawlers, for example, can burrow to depths of six feet or more.
Banana peels are an excellent worm food.
Earthworms are safe and fun to touch, as this Discovery Garden visitor proves.
Once every week, pour about five litres of fresh water into the Top Working Tray, which will flood down through the lower trays, ensuring the entire worm farm remains very moist. The sudden 'flood' will not harm the worms.
The salt absorbs all the water volume from the earthworm. The loss of water is caused by the high concentration of salt outside the earthworms cells. The organism becomes dehydrated and finally dies.
OSLO (Reuters) - Worms squirming on a fishhook feel no pain -- nor do lobsters and crabs cooked in boiling water, a scientific study funded by the Norwegian government has found.
According to new research studying neurons within microscopic roundworms, the answer is an emphatic 'yes'. They found that worms would choose to respond to a nearby odour depending on what they were 'thinking' about - suggesting they have free will just like humans.
