Is it Necessary to Deadhead Marigolds?
Marigolds are self-seeding annuals, growing, blooming, and seeding throughout spring and summer.
They die back, all before the first frost of winter but drop their seeds in the soil before perishing to grow back again.
Their flowering spell lasts around 5-6 months, during which you can deadhead the spent flowers off the plant.
Additionally, deadheading offers specific benefits to Marigolds. Let’s see some below!
- Deadheading Marigold helps conserve energy which in turn encourages a longer blooming period.
- It gives the plant a well-groomed look, contributing to much cleaner garden beds.
- Also, it discourages random self-seed sowing of the plant.
- It makes the plant more robust and bushier, with more stems and leaves to protect the buds.
- Deadheading spent flowers means the excuse to harvest Marigold seeds for growing the next batch of seedlings.
Mexican Tarragon, Lemmon’s Marigolds, and Mountain Marigolds are perennial Marigold varieties growing throughout hardiness zones 9 and above.
When to Deadhead Marigold?
Normally, the flowering spells for most Marigold varieties last 5-6 months.
Each yellowish-orangey bloom in the Marigold plant lasts only 1-2 weeks, after which their petals droop and turn brown, papery, and crisp.
Afterward, you can selectively continue to deadhead the spent Marigold flowers throughout the summer and fall until the first hard frost.
If you are growing Marigolds in large planters or garden beds, deadhead them every 3 weeks.
However, remove the spent blooms weekly to deadhead the Marigolds in small pots.
How to Deadhead Marigolds?
