Make your own Worm Compost – at home…

Whilst we are in lockdown today I’ve been adding some really good quality compost (well-rotted horse manure) into two raised beds here at the farm as I hope to plant lots of beans :) On this week’s Wiggly Podcast (back for lockdown!) I talk to Terry Walton about making our own potting compost so tune in for that recipe here:

My next task is to make my own compost and so I am going to base my own recipe on coir and worm castings with a sprinkling of rock dust.



I like Coir blocks on a practical level as it means we are not shipping lots of water around the country – the blocks are easy to use and don’t take up much space. Coir is a good alternative to peat and the other benefits include:

  • High water holding capacity.
  • Acceptable pH & EC.
  • Excellent wettability, superior to peat.
  • Ability to retain nutrients against leaching
  • Good drainage / aeration


Worm Casts

Easy to make in your worm composter – worm casts are packed with a lot of nutrients and minerals. Worm castings contain minerals such as concentrated nitrates, potassium, magnesium, calcium, and phosphorus. Worm castings are also a 100% organic fertiliser that can increase a plant’s yield, protect both soils around plants from diseases, and help the soil retain moisture.


Rock Dust

Volcanic rock dust is a fantastic natural source of minerals which helps to rejuvenate soils, helping boost soil fertility and plant growth


The recipe

Soak your coir and mix four parts coir with one part worm casts and a handful of rock dust each bucket full of compost. If you have sand add one part sand as well. 

This will make a really good all round compost and cost very little indeed. Get Growing all x
