Four Year Old and I started our fairy garden in a large pot today.
No photos yet as its just dirt with a saucer (pond) and upturned terracotta pot (house). We've sown some chive seeds to make big 'grass' and cress (for little grass).
Ideas include painting some large pebbles, adding a courgette plant (will give a thick 'trunk' and big shady leaves), a bean plant (beanstalk), paint the terracotta pot and add a flowering plant (not sure which one... how big do petunias grow?).
A little wooden bench would be good too.... and some bunting...
