Dahlia 'Breakout' problems — and how to fix them
Dahlia 'Breakout' (Dahlia 'Breakout') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Petal spotting and rain damage
The pale, soft blooms mark and brown readily in rain or damp. Site with good airflow and deadhead spent or weather-damaged flowers promptly.
Stem flop under bloom weight
The large heads break unstaked stems. Stake firmly at planting and tie in stems regularly as they grow.
Tuber rot
From cold, soggy soil or storing damaged tubers. Plant in free-draining ground, withhold water until shoots emerge, and cure tubers before storage.
Earwigs in blooms
Earwigs lodge in the dense petals and chew them. Trap them overnight in rolled cardboard or straw-filled pots and empty the traps each morning.
