FAQS

What temperature is too hot for a worm farm?

From hands-on experience, worms can tolerate a surprisingly wide temperature range, roughly about 10°–30°C (50°–90°F), but anything hotter than this quickly becomes too hot for a worm farm. To make sure conditions stay safe, I follow the same principles recommended for systems like the Tumbleweed Worm Farm by focusing on farm positioning in a shady, cool position with plenty of shade. During heat spikes, simple cooling action helps: take lid off, hose the whole unit, and hose down the exterior while keeping the bottom drainage tap tap open to release excess water. This supports moisture release, proper water drainage, stable temperature control, and effective heat management, maintaining a cool environment that improves heat tolerance, ensures worm safety, and protects long-term health in a consistently shaded location.

How to keep worm farm cool in summer?

To keep worm farm cool in summer, I rely on simple, proven techniques that work even during hot weather and sudden summer heat. When there’s advanced warning of a heat wave, I drape hessian or an old beach towel over the worm farm and keep moist using a sprinkler or dripper. As the moisture evaporates, evaporation cooling occurs, helping cool the worm farm on the similar principle used in the Australian invention called the Coolgardie safe. This cooling method supports effective heat management, improves moisture retention, and enables natural evaporative cooling. Combined with a breathable shade cover, it provides reliable farm protection, acts as a practical cooling strategy, and delivers steady temperature reduction during peak summer conditions.

Should worm farms be in sun or shade?

From practical experience, a worm farm should be kept in shade, not sun, because direct sunlight quickly overheats bedding and stresses worms, so I always keep out of sunlight and keep covered while ensuring the system stays well drained with proper drainage. Occasional sprinkling helps with moisture control, and every few weeks I add small amounts of wood ash, dolomite, or lime as soil amendments and mineral additives to prevent acidity, stop bedding from becoming too acidic, and maintain proper pH balance. Careful farm placement and shade placement reduce harmful sunlight exposure, while consistent acid control supports long-term worm health and system stability.

What to avoid putting in a worm farm?

From experience, it’s best to avoid putting problem items into a worm farm to keep conditions stable. I never include onion parts, leek parts, or shallot parts, and I limit orange skins, lemon skins, lime skins, grapefruit skins, and excess pulp, since too much citrus waste disrupts decomposition control. You should not add too much material in one go, and I never add more until the previous lot consumed, which helps with feeding control and overfeeding prevention. Any material added needs to be covered using hessian, felt, carpet, or underlay as covering materials, supporting clean waste management while respecting key food restrictions.

What time of day are worms most active?

From observing my bins closely, worms are most active during night-time, as they are generally active at night-time, which is when a lot of pooing happens and most pooing happens overall. Worms have no daily sleeping routine and no waking routine because it is always dark where they live, so their activity levels are guided by darkness rather than a clock. There are certain times when they are less active, and therefore doing less poo, reflecting natural shifts in worm behavior, feeding activity, and waste production shaped by their natural habitat and continuous activity cycle.
