Wally Richards – The Beautiful Worm Farm

Worms are the most efficient method of recycling household waste into high value nutrients for the garden.

Having your own worm farm is a great way to turn your kitchen scraps into liquid plant food and worm casts (virmicasts) which can then be incorporated into your gardens or containers.

There are about 3000 types of worm species but of these, only about a six or so are important to cultivation.

Eisenia foetida, commonly known as the Manure Worm, Red Wiggler or Tiger worm, has alternative bands of yellow and maroon down the length of its body. You know you have one when you pick it up, it thrashes about wriggling and squirming. The amazing attributes of the Tiger worm include being able to consume their own body weight in food each day. The daily food intake of organic material results in a wonderful, organic material called vermi-cast. They also produce 60% of their body weight in urine each day which is referred to as leachate. This leachate is very high in nitrogen and can be diluted 1:10 parts water for use as a highly nutritious plant food.

Tiger worms are surface feeders and they thrive in organic materials such as manure and kitchen scraps when these materials are mulched on top of the soil. Another interesting aspect is that they are a little like the Monarch Butterfly’s caterpillars in so much as they are distasteful to predators such as birds. Thus many birds will leave them alone and being surface eaters this is most important as they are otherwise easy prey.

These wonderful worms are the best compositors in the world, turning waste material into high value nutrients for plants to use.

Every day you probably throw out kitchen waste which clog up our tips and sewer systems.

Such a waste of wastes!

What if you could convert your wastes into top quality plant food (leachate) plus highly nutritious soil for gardens and containers (vermicast) and be able to collect these valuable products cleanly and simply?

Well now you can with a worm farm such as the “Worm-a-Round”.

The Worm-a Round is a special double bin that allows you to run your own Vermi-composting unit and collect the valuable plant nutrients. Simple to use, you start off with newspaper and kitchen wastes to which is added 250 grams of Tiger Worms. (These are available from worm farmers through out NZ). Each day you simply add your kitchen wastes for that day and once in full operation your Worm-A-Round bin can cope with 2kg of kitchen waste per day. A tap is on the lower, collector bin and each week you can collect about a litre of leachate. This can be stored for use as required.

If you think about it, that’s about $20.00 worth of top quality plant food a week!

Over the following weeks and months the worm population will increase until it reaches its optimum level (worms are self regulating in this aspect).

At this time you could remove some of the worms and place them in the garden under a layer of organic mulch. Mushroom compost would be ideal for this along with newspaper and kitchen scraps. You may like to add them to your own compost heap to get more action from it. If you don’t remove any worms it doesn’t matter as they will not overcrowd their home. It takes between 3 to 6 months to reach this point.

After a period of time vermicast will reach the top of the first tray and then the second tray should be added to the bin. Food scraps can then be placed in this top tray daily.
Once this top tray is three quarters full of vermicast most of the worms will have moved up into it. At this time you can remove the bottom tray (full of vermicast) for use with your potting mixes, as seed raising mix, mulch around plants, or for use under plants at planting time. It also can be added to non chlorinated water as an additional liquid additive in the garden.

Vermicast, like ordinary worm casts is a beautiful crumbly material just busting with plant nutrients. Each harvest will save you many dollars in potting mixes and other plant foods. Except for your initial outlay for the bin, instructions and worms the whole process will not cost you a penny in the future but will return you many dollars worth of products every week for years.

Vermicomposting is an interesting aspect of gardening and of great value to your plants as well as the important principals of recycling. It is an activity that the younger members of the family can enjoy and participate in giving them a better concept of nature and the world around them.

I currently throw my kitchen wastes into my plastic composter but have found that it has encouraged rats and mice this winter (mind you they do a fine job digging through the compost and aerating it). The Worm-a-Round is rat and mice proof so you wont have that problem.

Worm-a-Rounds are available through some retail outlets, worm farmers or by mail order. See

Vermicomposting is very popular overseas and is highly valued by people conscious of the need to recycle as well as gardeners both organically minded and otherwise.

Instead of taking out the kitchen scraps every day I have a plastic lidded box where the scraps are stored till full and then placed into either of my two Worm-a-Rounds.

A sound investment for the new year.

    worm farms are great – i live alone in a3rd floor apartment and its perfect om my balcony.

    no smell and I use the results for my tiny, v tiny but productive, space in the grounds below.

    Some of my neighbors laugh at my farm of 1000s and call me ‘the rich farmer with heaps of animals’
