RHS site for plants and their cultivation needs and if that doesn't answer then a wider search.
Also for finding plants and good nurseries for stocking this new garden with very different soil and weather from the last.
Finding a polytunnel, new garden group, man with a mini digger, bulk supplies of chipped bark, local weather, plant fairs, hard landscaping supplies etc.
This site for friendly chat and advice based on personal experience.
Seed packets for sowing and planting times.
