My dahlias.....mostly now all over 5', except for dwarf varieties......are staked in mid spring when growth is vigorous. Three 6' strong bamboo canes...topped with eye protectors.....and string provide (hidden) support all summer .
Melanie, cut off all broken stems and clear them away. Scatter some fish blood and bone around them and they should regrow at this time of year. Or, dig up the tubers and pot them....they will for sure be ok for next year. Hiw about planting a helenium there? Should be some sizeable ones in gc now. Or some cosmos plants....they will be growing fast now and give you plenty of colour. Or,,how about a tall grass there instead? Miscanthus will fill in well
