I’ve got worms!
The last time I made that announcement, our family doctor curled his lip and said, “How very distasteful!” But I was five and I had been eating dirt.
This time, I am delighted with the news because the worms are back where they belong – in the dirt in Bournac.
When we first started planting (see Chapter 7: Help, there’s a house in our garden), we discovered that the earth around here is made of clay with a lot of limestone and some house debris thrown in just to make life interesting. And not a worm in sight.
I am a big fan of worms. I am happy to pick them up with in my fingers; I always cover them over when I find them in the garden and I am distraught if I find I have skewered one on a garden implement by mistake.
(There now follow scenes of worm violence that may upset some readers…)
My interest in worms started in biology class when I was 13. We had been instructed by our science teacher Mrs Aidley each to bring a worm for dissection, causing much squealing and murmuring in class. Since she had mastered the one-line put-down of pubescent females, no one dared arrive sans worm and Mrs Aidley then proceeded to pick them out of various jam jars and sandwich boxes and place them in a glass beaker.
What ensued has stayed with me ever since. She poured alcohol on the little pile of creatures and I can still see them thrashing about in their death-throes. A dead worm was then distributed to each girl – I was pretty miffed because I’d dug around for a good 20 minutes looking for a big, fat specimen and was handed back a spindly character, probably just entering worm teenage. We then had to cut them open lengthways with scissors and rummage around for worm brains and organs. Imagine the sights and sounds of 30 scalpel-wielding schoolgirls hacking their way through a head the size of cotton bud.You can tell that this particular biology lesson scarred me, not just the worms. I blame Mrs Aidley – I can still her standing on the platform at the front of class, holding up the voice box and wind pipe of a cow that she had managed to wrestle off a farmer. Unfortunately, the wind pipe was still attached to two massive lungs.
But I digress…
Worms are vital to the health and structure of soil so when they’re not there, it’s a sure sign that something is wrong. Unfortunately, there’s no missing worm hotline so it was up to us to encourage them back.
Worms burrow away happily, depositing worm poo through the soil and creating tunnels lined with worm goo which is high in nitrogen. Plant roots seek out these tunnels and grow through them, sucking up the nutrients left behind by the slitherers.
There are different steps you can take to make your garden an earthworm mecca:
- Keep the ground covered in organic matter – in another words, mulch with leaves or compost, rather than stones. The worms will pull the mulch down into the soil to eat it. Next autumn, notice how fallen leaves start poking up out of the soil – an earthworm party will be going on somewhere nearby.
- Keep the soil moist – the best way is by mulching, but watering also help if there is no rain for a while.
- Only use organic products in your garden – above or below the soil line. Are you more likely to want to swim in water that is clean and pure, or splash about in a load of toxins?
- Avoid digging the ground – even a quick turn of the soil will kill the micro-organisms (mycelium) that help with the decomposition of organic matter in the soil, thereby ensuring a constant supply of readily available nutrients for plants and soil-dwelling animals, such as earthworms. You will also disturb the worms’ network of tunnels which can take years to establish. If you want to aerate compacted soil, stick a fork in and wiggle it about gently.
- Feed them – bury kitchen waste (raw, not cooked) in the ground at intervals. The worms will travel between them to snack on the food and drag nutrients along in their wake, as well as mixing the rotting matter through the soil for you.
We did numbers 1 to 4 and within a few months, I found that the beds where we had mulched were teeming with worms. It will still take time for the worm action on the mulch to improve the soil, but we’re off to wriggling start.
To paraphrase Kevin Costner, “Feed them and they will come.”
