Marigold French Bonita Mix
Tagetes patula 'Bonita Mix'
These compact French marigolds are garden workhorses, producing masses of 2-inch ruffled blooms in warm shades of yellow, orange, and red-bronze throughout the growing season. Beyond their cheerful appearance, they're prized by organic gardeners for their natural pest-repelling properties, helping to deter nematodes, aphids, and other unwanted insects. Their neat 8-10 inch height makes them perfect for borders, containers, and companion planting with vegetables.

Succession Planting
Bonita Mix blooms continuously once it gets going, and a single planting will carry you 8-10 weeks before it starts looking ragged. If you want a fresh-looking border all season, start a second round indoors about 6 weeks after your first, or direct sow a second batch in late May or early June. In zone 7, stop direct sowing by late June — plants started after that won't hit their stride before heat and humidity invite Botrytis, and they'll barely bloom before frost shuts things down.
There's no need for tight 14-day successions the way you'd run with lettuce or radishes. Two rounds — one transplanted in April and a second started in late May for a June transplant — covers most situations. Deadhead consistently and the first planting will overlap cleanly with the second.

Drainage: Good Drainage, Occasionally Dry. Height: 0 ft. 6 in. - 1 ft. 0 in.. Spread: 0 ft. 6 in. - 1 ft. 6 in.. Spacing: Less than 12 inches. Growth rate: Medium. Maintenance: Low. Regions: Coastal, Mountains, Piedmont.
Harvesting
Edibility: Flowers are used to make refreshing drinks and the leaves are used for flavoring.
Storage & Preservation
Fresh marigold flowers keep best stored loosely in plastic bags in the refrigerator, lasting 3-5 days. For longer storage, gently separate petals from flower heads and store in airtight containers in the fridge for up to one week.
To dry marigold petals for year-round use, spread them on screens in a warm, dry area away from direct sunlight. Properly dried petals will be papery and retain good color. Store dried petals in airtight jars for up to one year—they make an excellent saffron substitute for coloring rice and other dishes.
You can also freeze whole flowers in ice cube trays with water for decorative drink garnishes, or preserve petals in vinegar for 2-3 weeks to create a colorful, mildly flavored cooking vinegar. Oil infusions work well too—cover fresh petals with olive oil and let steep for several weeks, then strain.

Companion Plants
French marigolds have a well-documented chemical relationship with root-knot nematodes (Meloidogyne spp.) — Tagetes patula roots exude alpha-terthienyl, a compound that's toxic to nematode larvae in the soil. That's why they're planted alongside tomatoes, peppers, and cucumbers: those crops draw heavy nematode pressure, and a dense border of marigolds set about 12 inches out from the crop row can suppress populations meaningfully over a full season. NC State Extension recommends leaving the plants in the ground after flowering rather than pulling them, so the roots keep releasing that compound into late fall. Carrots and lettuce benefit from the same arrangement — both are shallow-rooted and nematode-susceptible, and a 6-12 inch marigold won't shade them out. Zinnias and nasturtiums work as neighbors mostly because they pull in parasitic wasps and hoverflies without competing for the same resources.
Beans are the one to keep well clear of. Tagetes patula produces allelopathic compounds that inhibit bean germination and stunt early root development — you'll see reduced stands and seedlings that never quite take off. It's not a subtle effect. Fennel brings its own allelopathic reputation and tends to suppress whatever's nearby, so pairing it with marigolds just creates a competition neither plant wins. Cabbage family crops don't have a sharp chemical conflict with marigolds, but they're cool-season feeders that want different timing and heavier nitrogen than a warm-season annual flower needs, so the practical overlap is limited.
Plant Together
Tomatoes
Marigolds repel nematodes, aphids, and whiteflies that commonly attack tomatoes
Basil
Both plants repel similar pests and basil benefits from marigold's pest-deterrent properties
Peppers
Marigolds deter aphids, spider mites, and other pests that damage pepper plants
Cucumbers
Marigolds repel cucumber beetles and other harmful insects
Carrots
Marigolds help repel carrot flies and other root pests
Lettuce
Marigolds deter aphids and provide light shade for cool-season lettuce
Zinnias
Both attract beneficial pollinators and have similar growing requirements
Nasturtiums
Both serve as trap crops for aphids and attract beneficial insects
Keep Apart
Beans
Marigolds can inhibit bean growth through root secretions and allelopathic compounds
Cabbage Family Plants
French marigolds may stunt growth of brassicas like cabbage, broccoli, and kale
Fennel
Strong allelopathic properties inhibit marigold growth and most other garden plants
Pests & Disease Resistance
Resistance
Good resistance to most diseases
Common Pests
Spider mites, aphids (though they repel many other pests)
Diseases
Root rot from overwatering, gray mold in humid conditions
Troubleshooting Marigold French Bonita Mix
What you'll see, why it happens, and what to do about it.
Tiny webbing on the undersides of leaves, with stippled or bronzed foliage — usually shows up during a dry stretch
Likely Causes
- Two-spotted spider mite (Tetranychus urticae) — thrives when temps climb above 85°F and humidity drops
- Dusty conditions, which accelerate mite reproduction
What to Do
- 1.Blast the undersides of leaves with a strong stream of water every 2-3 days to knock the population down
- 2.Apply insecticidal soap or neem oil at dusk — repeat every 5-7 days for at least two applications
- 3.Keep soil evenly moist; water-stressed plants get hit harder and recover slower
Stems turning black or brown at the soil line, plant wilting even when the soil is wet
Likely Causes
- Pythium root rot — a water mold pathogen that moves in fast when drainage is poor
- Overwatering or planting in heavy clay that doesn't drain between rains
What to Do
- 1.Pull affected plants — they won't recover once the crown is gone
- 2.Let the bed dry out for 7-10 days before replanting, and amend with perlite or coarse compost to open up the soil structure
- 3.Plant into raised beds or mounded rows; Bonita Mix sits only 6-12 inches tall and doesn't need much root depth, so drainage matters more than depth
Gray fuzzy patches on petals and upper leaves, often after several overcast or rainy days in a row
Likely Causes
- Botrytis cinerea (gray mold) — spreads fast in cool, humid air with poor circulation
- Deadheads left on the plant, which give the fungus an easy entry point
What to Do
- 1.Remove and trash (don't compost) any affected flowers or leaves immediately
- 2.Deadhead every 3-5 days during humid stretches — spent blooms are where Botrytis gets its foothold
- 3.Space plants the full 6-8 inches apart and avoid overhead watering in the evening
