Though Marigold represent a single type of flower their variety is endless. They can be single or double and come in many colours which can range from orange, yellow, bi-colour even white.
The best thing about growing marigold is you don't need to think much about the soil. They generally grow in any kind of soil, provided it is well drained and has some nutrients in it. Plant them in a place which receives sufficient amount of Sunlight and chances are that you will get a good amount of yield.
Like most other plants Marigold can be grown both from transplants and from seeds. Although you can easily buy seedlings from your local nursery shops, you can use a much cheaper option of starting from seeds.
If you are growing from seeds try planting 2 months prior to frosting date. Use soil-less media to fill seedling trays. Put the seeds and cover them with the mixture. Then cover the tray with plastic wrap keep the tray in a worm place. You don't require any sunlight for seed germination.
It generally takes 3-4 days for germination but you should check the tray everyday to see any sign of germination. Once you see the germination remove the plastic cover and move the tray in the sunlight.
Once they develop two sets of true leaves you can transplant them to their permanant pots or in the garden.
Marigold is a plant which requires very little care. You just need to provide them water regularly so that the soil doesn’t go dry. Depending on the variety you may need to put some support to protect them from strong winds.
While growing the plant you need to remove the dead stems and leaves from the plant so that seeds and flowers can grow easily. Unlike Tomato or Roses the pruning is not that essential.
Pest and prevention:
Marigold plants have a pungent odour which help them repel pests. So in most cases you probably would not need any pest preventive system from outside. Besides, the roots of the plant help in reducing nematode population beneath the soil.Due to this unique property marigold plants are used in companion planting. You can find more about that in this article.
Additional point:The petals of the Marigold flower are used to add colour and flavour in many dishes across many cultures. It is also an good alternative to the expensive saffron, and used in many rice preparation (like Biriyani). More on edible flowers in this article.
