Growing marigolds from seeds is a fairly easy process, they can be sown right into your containers! Seeds should be sown when the weather has officially warmed up for the year. Sow the seeds into your container when night temperatures are fairly warm. If night temperatures dip below 50, your seeds will take longer to germinate or may not ever germinate. Seeds will take a couple of weeks to germinate, so keep this in mind if you are wanting to add other flowers to the same pot.

If you live in a climate where a chance of frost is still possible in the spring, be sure to bring your pots in overnight or cover them with a frost cloth to protect them from freezing temperatures.

To transplant, create a hole in your container where the marigold will go. Simply remove the nursery container from the plant and set it aside. Gently loosen the roots up on the plant, this will help it establish once planted. Set the plant into the hole, and fill around the root ball – the soil line should be level with the container when it’s all said and done. You don’t want to plant too deeply, as this could cause the stem to rot. Planting not deep enough may hinder the roots from adapting to the new soil.

Choosing a Location – Marigolds grow best in full sun and being in a location that receives shade can hinder them from blooming or make your plants leggy.
Maintenance

Marigolds are low-maintenance plants once established. They will benefit from frequent deadheading and a consistent watering routine.
