Lime-free grit sand is included to allow excess water to drain from the compost and so prevent water-logging. It also adds weight and provides stability for pot grown plants The institution made the formulae generally available, but never manufactured the composts for sale nor benefited financially from their production. [3] Original formulae [ edit ]Multi-purpose compost was traditionally peat-based but for a number of years there has been a desire to reduce the use of these composts due to the devastating environmental effects of peat extraction. A number of different peat-free composts are now available, involving different base materials such as coir, wood-fibre or composted bark. Since these composts may differ significantly in their structure and composition, their effect on plant growth and flowering may also vary.

The mixes Container herbs are very easy to look after - they don't need fertiliser, and actually benefit from being planted in quite poor soil. Many varieties also do not need much watering, particularly Mediterannean herbs such as sage, rosemary and thyme. Read our guide to growing Mediterranean herbs.
