The marigold has been out of fashion for 150 years. In 1858,
the New England Agricultural Warehouse and Seed Store Catalogue deemed
marigolds “old-fashioned.”
Yet you’d be hard-pressed to find another annual that’s as
covered with bloom for as long a season, let alone one that’s so trouble-free as modern hybrid marigolds. Plus, they're cheap. Any nursery will sell you a six-pack in colors ranging
from yellow to maroon and all sorts of blends for under $5. And the supreme varieties are
available by seed, which you can buy for roughly a dime a piece.
Which varieties to plant?
Garden marigolds are either French of African. French marigolds grow
8-12” tall with 1-2” flowers. Africans are 10”-20” tall with 2-4” flowers. I
prefer Frenchies both because of their more exotic coloration and because their
flowers are less likely to rot in the rain.
Here are highly-rated varieties:

Growing marigolds
Easiest is to buy six-packs or 4" pots in any nursery or even supermarket. Just pop ‘em into average soil in a sunny location. Add
fertilizer and regular water and, voila!
In relatively warm climates, you can
plant them as late as early September and get a month or three of bloom before
cold weather sets in.
You may be less likely to find the above varieties in
pots or six-packs. You’ll more likely see unnamed varieties or, Bonanza Yellow, Gold, or
Orange and the Durango series of Frenchies and Antigua or Inca II Yellow, Gold,
and Orange Africans, which are all just fine although perhaps a notch below
those above.
Fortunately, marigolds are among the easiest plants to grow
from seed. Most experts advise you to simply sow them directly in their
permanent sunny home as soon as frost has passed. Just cover them with ¼” of
soil and keep them moist.
Especially if you live in a humid climate, to prevent or
reduce fungal disease, water just the soil, not the leaves, for example, with
drip irrigation or by watering the soil next to the plant, not the plant
itself.
Not essential. But to maximize rebloom, pull off the dead flowers.
And that’s it!
Of the hundreds of plants I’ve grown, I find marigold to
give the most pleasure for the least cost and effort. I think it’s time for
them to come back into fashion.
