We entered the glasshouses via the potting house, which contains a whole range of pots, growing media and tools for propagation.

The growing substrate typically used for most seed germinated at the Botanic Garden is a neutral peat-free compost composed mainly of composted bark, coir and composted green material. 
Penny explained the finer details of the growing media used, “This compost can be altered by sieving out larger chunks f…

Even more recent examples include the siege warfare occurring in many parts of Syria where the act of starvation is used to make opposing sides submit. The devastation and suffering as a result of food shortages to humans is untold during …
