Marigolds can also be sown in the vegetable garden as an edible flower

Sow seeds in spring

Calendula officinalis

Common Name

Zingy yellows and oranges will brighten up your garden in the summer if you sow some marigolds in spring.

Growing Tips

Growing conditions

Marigolds like to grow in well-drained soil in full sun.

When to grow

Sow from March to May and they will flower from summer to autumn.

What you need

  • A packet of Calendula seeds (varieties that can be sown from March include ‘Fiesta Gitana’, ‘Daisy Mixed’, ‘Greenheart Orange’ and ‘Lemon Zest’)
  • Gardening gloves
  • Rake
  • Trowel
  • Plant label

How to grow

  1. Marigolds can be sown straight in the ground where they are going to flower, so make sure the soil you sow is weed free by using a trowel to remove the weeds.
  2. Rake the soil to a fine tilth (a fine, crumbly texture) and make some drills 12mm deep. The rows should be spaced about 30cm apart. If you made a measuring stick from last month’s activities you could use this to help you.
  3. Sprinkle the seed in carefully and cover them up with soil. If the plants are crowded as they grow, thin them out to about 30 cm apart.
  4. The petals from marigolds are edible and can be added to salads – why don’t you try them?
