Worms love to eat coffee grounds, and that's great news for your garden. Add coffee grounds to your compost pile to help attract worms, which help speed up the process of turning food scraps into compost. You can also add coffee grounds directly to the soil, but you'll have to be careful not to overdo it.
Earthworms consume coffee grounds and deposit them deep in soil. This may account for noted improvements in soil structure such as increased aggregation.
So, coffee grounds should be added in moderation, as the acid in coffee beans can lower the pH level of the compost, making it inhospitable to some types of worms and harming them.
Pre-compost your coffee grounds to promote microbial activity. Limit the amount of coffee grounds added to 25% – 50% of a worms diet. It's a good idea to add small amounts first to see if your worms like it or not. And to use pocket feeding so that your worms can choose to feed on it as they please.
Coffee grounds have about the same amount of nitrogen as grass clippings – 2% or so, meaning they heat up quickly when added to compost and help turn the entire pile into a beautiful dark rich soil. They are also very suitable for the worm farm, with those little guys loving used coffee grounds.
Items you cannot compost in a worm bin:
Lemon, lime, orange or other citrus peels and juice (in excess this will make the soil too acidic) Onions and garlic (a good rule of thumb is if it makes you smell, it makes your worm bin smell) Meat, fats, grease, bones or oils (no butter, lard, stocks, soups, etc)
Banana peels are an excellent worm food.
Worms hate: meat or fish, cheese, butter, greasy food, animal waste, spicy and salty foods, citrus.” The food-to-worm ratio is not precise, nor is the amount of castings they will produce. The rule of thumb is that a pound of worms will eat one to two pounds of food in a week.
She recommends that grounds make up no more than 15 to 20% of the total compost volume. Because they are acidic, coffee grounds make good acid mulch. Of course, too much of anything is just too much, so apply coffee grounds in limited amounts. Kit recommends a layer no thicker than half an inch.
Coffee, cola and other caffeine based drinks act as stimulants. Studies have found that the effects of a cup of coffee or a glass of cola are noticeable after just 10 minutes, but the peak caffeine concentration in the blood occurs after 45 minutes.
Coffee grounds, as an organic material, can be added to your compost pile. Worms like coffee grounds, so you may want to put a layer of coffee on the bottom of your pile to attract worms.
Yes, caffeine can be toxic to small animals (like worms) if the dosage is high enough.
Worms will eat anything that was once living, Leftover vegetable scraps, fruit and vegetable peelings. Tea leaves / bags and coffee grounds.
Earthworms eat soil! Their nutrition comes from things in soil, such as decaying roots and leaves. Animal manures are an important food source for earthworms. They eat living organisms such as nematodes, protozoans, rotifers, bacteria, fungi in soil.
Coffee grounds are highly acidic, they note, so they should be reserved for acid-loving plants like azaleas and blueberries. And if your soil is already high in nitrogen, the extra boost from coffee grounds could stunt the growth of fruits and flowers.
For example, peanuts, soy, milk, and eggs. These contain deadly toxins for some, while others safely consume them daily. Compost worms, however, seem able to stomach nearly anything grown from the ground.
Eggshells provide calcium, which reduces acidity in the bin. This prevents high acid conditions that can harm your worms. Also, crushed eggshells provide grit to aid the worms' digestion. And, it is believed that eggshells help worms in the reproductive process.
Composting worms can absolutely be fed with crushed shells from eggs. You should know that compost worms will eat just about anything that's organic (all except meat, seafood, poultry, dairy, oily, or spicy stuff).
Yes, in moderation, bread, and in fact, all grain based foods, are worthy of your worms' processing power. Stale bread remains just as full of nutrients and building blocks for worm growth as the fresh stuff. However, these starchy foods can end up a gooey mess.
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. Adding water is especially important in the hotter months of the year.
Yes! You can add dry grass clippings and deciduous leaves to your worm farm, as long as you keep food scraps and dry waste balanced. Avoid adding fresh lawn clippings, evergreen or native leaves, and sticks or woody stems.
The molds that form on most vegetables are usually OK, but the molds on some fruit and bread can be problematic. If you're in doubt, try a small amount first and see if the worms are bothered by it. If not, then it's probably OK to use it, otherwise, you should put them into your backyard bin instead.
