Creating the Best Conditions for Worms
Starting a worm farm can be a gratifying business that can bring many rewards. However – before you start thinking about things like profitability, environmental benefits and getting tradesman insurance – the first thing to consider is creating the right conditions for your worms. Earth worms can reproduce at an almighty rate – they begin the reproduction process once every 27 days – and they can also live for up to ten years, so the potential for harvesting productive worms is huge. However, this largely depends on the conditions you create for your worms. There are four things you need to consider when creating ideal conditions, which are outlined below.
Temperature
Number one is temperature. Worms require a temperature of between 60 degrees to 80 degrees F. They also prefer shaded or dark conditions as, although they can’t see, they can sense light and will naturally try to hide if exposed to it. Ensure that you provide enough depth to the soil so that the worms can bury themselves adequately. They do not like warm conditions, so make sure your worm bin is not kept in areas that are exposed directly to sunlight; a shady spot in the garden, or better still under a shelter, would be ideal. Ensure that you regularly check on the temperature of your worm bin (you can use a thermometer to be sure); if the temperature gets to high, carefully move the soil around (being sure not to harm the worms) with a hand-held spade to circulate the air and cool down the top layers. If the worm bin gets too hot you can also add a little water – the best way is to use a spray can so your bin doesn’t get too soggy. When using water, just ensure that you have adequate holes at the bottom of the bin so that excess water can drain away.
Moisture
The second factor you need to consider when creating the perfect environment for worms is moisture. It can be tricky to create the right moisture levels; worms will not survive in a dry environment, yet they will drown if exposed to too much water. The level of moisture you should aim to create is around 30%. To achieve a moisture of this level, you first need to ensure your worm bin is a) not in direct sunlight and b) not exposed to rain or other natural elements. Then, you need to regularly spray the farm with water. As mentioned above, make sure you have an adequate drainage system in the bottom of the bin so that water can flow away rather than clog and pose a drowning threat to your worms.
Oxygen
The third factor is oxygen. Like most living organisms, worms need adequate amounts of oxygen in order to survive. They “breathe” oxygen through their skin. In order to ensure you are giving your worms enough oxygen, make sure you pierce holes in your worm bin. Don’t make your holes too large – you don’t want soil to seep through them. Worms need a constant flow of fresh air, so position your worm bin in a place that has a good flow of natural air. You can also help by gently turning the soil – as mentioned in the first point above – to aid the flow of oxygen within the bin.
PH Levels
Last, but not least, ensure that your bin has the right PH levels. If conditions are too acidic for your worms, it will affect their ability to breathe properly; worms breathe through their skin and too much acid burns the skin. If conditions are kept too acidic for long enough, the worms will die. The correct PH level for an ideal worm farming environment is 7 (neutral). Invest in some litmus paper strips to help you measure acid levels and make sure you monitor this regularly (weekly). As a general rule, do not feed your worms any foods that have a high acid content, such as fruit or anything else containing sugar. These foods will increase the acid levels in your soil, taking the PH level below 7. If your PH rating dips below 7, you can add products such as garden lime or others that are high in magnesium to add alkaline and bring the PH level back to neutral.
