FAQs

Are the flowers truly edible?

Yes, 'Discovery Yellow' marigold petals are edible and have a distinct citrus taste, making them a great addition to salads and seafood.

How far apart should I plant them?

Plant these marigolds 30cm apart to allow enough room for their 35cm mature spread.

Can I grow these in pots?

Absolutely. Their tidy, dwarf habit makes them an excellent choice for containers and patio pots.

When is the best time to sow these seeds?

Sow in early spring indoors to get a head start before planting them outside once the frost risk has passed.

Do these require full sun?

Yes, for the best bloom production and plant health, they should be placed in a position that receives full sun.

How long will they bloom?

You can expect continuous flowering from July through September.

Troubleshooting

Seeds failing to germinate

Ensure the temperature is maintained between 21-24C and check that the compost is moist but not waterlogged.

Leggy or weak seedlings

The plants likely need more light; move them to a brighter location after the initial germination period.

Stunted growth after transplanting

Ensure the plants were properly acclimatized over 10-15 days before placing them in full, outdoor sun.

Pros and Cons

Pros

  • Excellent heat and weather tolerance
  • Compact, tidy plant habit ideal for containers
  • Striking 6-7cm fully double yellow flowers
  • Edible flowers offer culinary versatility
  • Highly reliable F1 hybrid genetics

Cons

  • Requires frost-free conditions for outdoor planting
  • Sensitive to overwatering during the seed germination phase
  • Limited to sunny positions for optimal flowering

Setup, Compatibility & Care

Start your seeds in early spring using a high-quality seed compost. Lightly cover the seeds and maintain moisture without saturation, sealing the tray in a polythene bag to create a greenhouse effect until germination occurs (typically 5-10 days at 21-24C). Once seedlings are large enough, transplant them into 7.5cm pots and move them to a cooler environment. Always harden off your plants for 10-15 days before transitioning them outdoors. Ensure they are planted in a sunny spot only after the last risk of frost has vanished.
