Name: marigold, French marigold (Tagetes patula), Mexican or African marigold (Tagetes erecta), signet marigold (Tagetes tenuifolia)– not to be confused with the calendula genus, which are frequently called marigolds but are actually in the daisy family.
Height: varies according to variety, from 10cm to 1m.
Foliage: pale green feathery leaves.
Climate: all except tropical.
Soil: moderately fertile, well-drained soil.
Position: full sun or part shade.
Flowering: daisy-like or carnation-like flowers in gold, orange or bronze shades in summer, autumn and spring. Remove spent flowers.
Feeding: feed with liquid fertiliser monthly, don't overfeed.
Watering: water well during hot periods.
Marigold comes in a range of varieties, including the tall upright African marigold with big bold flowers (Tagetes erecta), the elegant, eye-catching and quite compact French marigold (Tagetes patula) and the dainty signet marigold (Tagetes tenuifolia), massed in rockeries or containers. All have edible flowers, and in many countries these are often used in garlands and decorations for festivals and religious events.
Marigold is great for massed displays in flower beds, in pots or as an ‘indicator plant' to detect powdery mildew, or repel nematodes in vegetable and herb gardens.
Planting marigold seeds
1. Sow seeds directly into a sunny, well-drained garden bed once the soil is warm in spring, or get a head start and sow into pots in late autumn.
2. Keep them protected, and move them into the sun once the plants have grown.
Planting marigold punnets or pots
1. Remove the plants from the punnets or pots.
2. Separate them if they were in punnets.
3. Plant the marigolds in the garden 20–30cm apart.
4. Water well.
Marigold plants germinate from seeds quickly, so you should see flowers within 8 weeks. They thrive in full sunshine, so all you need to do is give them a sunny spot and let them do their thing!
An added bonus of planting marigolds is that they can be used for companion planting. Marigolds are a natural insect deterrent, so can increase the growth and health of fruits and vegetables such as broccoli, kale, cucumbers, eggplant, melons or tomatoes.
Give your marigolds a deep drink when the top few centimetres of soil are dry. They hate to be wet and soggy, so never overwater, particularly in pots. If they're allowed to stay wet they may develop root rot. Feed them with a liquid fertiliser once a month according to directions, but be careful not to overfeed. If the soil is too rich, your marigolds may become weak and not flower well. Pinch out spent blooms to keep plants bushy and to prolong flowering.
If rust or powdery mildew becomes a problem, treat with an appropriate fungicide. Look out for aphids, too. If the infestation of these sap suckers is small, you can hose them off or squash them, but if there are too many, spray them with an appropriate insecticide. Snails love nearly all seedlings, and marigold plants are no exception, but there are plenty of great deterrents such as snail and slug barrier.

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.
