Easy-Water Compost

If you don't like the idea of sterilizing soil in your microwave (and who can blame you?) and you find multi-purpose compost difficult to water, then you can lighten it with perlite/vermiculite. Perlite is especially good, since it is stable and holds on to moisture whilst allowing the compost to breathe.

Perlite/Compost Mix

• 1 part perlite
  
• 3 parts multi-purpose compost
  

For something with a little more weight, try:

Perlite/Sharp Sand/Compost Mix

• 1 part perlite
  
• 1 part sharp sand
  
• 6 parts multi-purpose compost
  

These mixtures should make watering much less hazardous. Perlite can be purchased in most garden centres/gardening stores. It's not expensive and is easy to use.
