Over the past few months our worm farm has gone from bad to worse. The farm was in an old bath tub (see above) that we bought cheaply at the recycle shop. I set it up a few years ago in the bush-house and since then we've been regularly harvesting worm castings and worm liquid. Then the rats discovered it. They found they could get in under the lid so Hanno attached a more secure lid for me. That worked for a while but they chewed a hole in the side of the tub where it had started to rust. There was no stopping them, and not only did they eat the food put in there for the worms, they ate the worms too! Has anyone else had that problem?
So I bought a smaller plastic worm farm. It’s made from recycled plastic, has four trays and best of all, it’s rat-proof. I set it up yesterday, following the simple instructions that came with it. The few worms the rats didn’t find and a new box full of worms have been installed to do their thing.
I love using worm castings and liquid in the garden and in pots. It’s the most gentle, but effective, fertiliser and adds beneficial microbes to the soil, another big bonus. We also use a lot of comfrey and now rarely have to buy any commercial fertiliser. This is a big saving when you garden almost year round and to have natural fertilisers like these means we can boost plant growth without adding anything we don’t want.
If you haven’t yet discovered how wonderful worm castings are, I encourage you to try them. One of the tricks to long term backyard vegetable production is to produce good quality organic food at the lowest possible cost. Saving seeds every year (as long as they're open pollinated/heirloom seeds) and making your own fertiliser will help you do that.
