It’s that time of year when green-fingered folk roll their sleeves up
and start digging in their quest for garden glory. With many of us
leading busy and stressful lives, gardening can also be a relaxing
way of changing pace. The BBC does a great job explaining garden
basics at this website, and offers practical advice and tips. There is
an exhaustive flower and plant database, and for each of them you’ll
find a profile, growing information and a problem solver. The best bit
is the planting section, which gathers useful tips ranging from ‘plant
a climber’ to ‘plant a tree’.
