Overview
At this time of year dahlias are producing stunning showy flowers, but they lose impact if the stems flop forward under the weight of the flowers. To get the best dahlia floral display, tie their stems to canes as they grow to give them some support.
Do it:
June - August
At its best:
July - September
Takes just:

How to do it
-
Check dahlias each week; if they're starting to flop tie the main stem to a supporting cane or stick with garden string. Don't tie the string too loosely, but allow a little room for growth.
"Tie the stem to the cane in one or more places to give the plant maximum support."
