How to Grow Marigold Flowers:
Marigold plants like rich, well drained soil, but are very tolerant of average to slightly poor soils. Improving your soil quality will produce much healthier plants and flowers, so add plenty of compost. Add a general purpose fertilizer once a month.
Once your Marigolds are established, they should grow well, even if left unattended. Soil should be moist, but not wet. Water them during dry periods, once or twice per week.
Add mulch around the plants for appearance and to keep weeds down.
Around mid-summer, your plants will begin to produce flowers and will continue to do so up to the first frost. You do not need remove dead flower blooms, except for appearance.
Marigolds are annuals and susceptible to frost. They may survive the first light frost with only a little damage. They will not survive a hard frost or freeze
Insect and Disease:
Insects largely avoid Marigolds. Insects do not like it's pungent odor. This is why Marigolds make good companion plants. You can even make an insect repellent spray from these plants.
While insects avoid Marigolds, slugs can do major damage. Slugs like to slither up the stem and chew on the leaves. They can destroy an entire flower garden of Marigolds. They can be seen on the plants overnight, in wet weather and early morning. If an infestation occurs, treat quickly to avoid major damage.
