Green-finger tips
In his handbook, On Guerilla Gardening, Richard Reynolds outlines campaign tactics. Here's a list of essential items in any would-be guerilla gardener's arsenal:
Seed bombs
In its purest and simplest form, guerilla gardening is little more than scattering seeds in places where, with time, they will sprout to fill the air with colour and scent. Some veterans have even fashioned gun- or grenade-shaped 'bombs' of damp compost mixed with seeds.
Tough plants
The cheaper and hardier, the better. Choose varieties that can withstand cold, drought, neglect and abuse by pedestrians, road users and dogs.
Bulbs
Hidden time bombs whose impact returns year after year. Guerilla gardeners often fill their pockets with daffodil bulbs and pop them into neglected pots or around the base of trees on grassland as they pass.
