In the Autumn l planted a patch of mustard 5x3m. Recently I turned it over and dug it in a full shovel deep but did not see any worms, and have not over the years. I’ve put in compost and horse manure and I have plenty of weeds. Should I be worried?
The success to getting worms in your garden is by adding copious amounts of organic matter into your soil. This can be achieved through the addition of Daltons Compost and or by growing green manure crops like mustard or lupins and digging them into the soil. This organic matter is the source of food for worms. However, if your garden shows no signs of a worm population over a period of time as you’ve described, it may be necessary to import some worms into your garden. You can do this by borrowing some from a friend’s compost bin that is heavily populated with worms. Alternatively source them from a worm farm.
In order to maintain the worm population it is essential to keep adding organic matter to your garden. If you have a compost bin which also doesn’t have a large worm population, it maybe beneficial to introduce some new worms to this as well. One important thing to note when emptying your compost bin is to retain the bottom 20-30cm of compost before refilling your bin. This means the worms will repopulate the new compost.
Ensure your compost bin is not placed on a hard surface eg: concrete, as this stops any movement of worms and beneficial microorganisms into your compost. The key to successful composting is not to let the compost become too wet in Winter months, nor too dry during the Summer months.
