How to grow calendula?
Growing calendula is a very easy job. As it is a herb that’s why it doesn’t require much care to grow and prosper. But you need to know few points. Such as growing season, potting mix, pot selection, propagation, transplantation, sunlight, watering, fertilizers, pest and disease management, etc.
You can germinate calendula from seeds in late summer or fall in tropical to sub tropical countries like India, and during early spring in hilly or temperate regions that have colder climate. In temperate regions it grows as short lived perennials.
But if you are living in tropical regions then you can grow calendula as winter flowering plants. The best sowing time is from September to November.
Best sowing temperature is in the range of 16 to 18 degrees celsius, above this temperature germination rate decreases.
Potting mix is a necessary factor to grow a plant successfully if you want to grow them in pots. This alluring flowering plant loves well drained soil that is rich in organic matter.
To germinate seeds, you can prepare germination potting mix with 60% normal garden soil + 20% river sand + 10% any organic compost + 10% neem cake fertilizer, mix them together.

You can grow this flowering plant even in very small pot ranging from 6 inches to 10 inches pot, you can select earthen, cemented or plastic pots depending on your choice, make sure that the selected pot has at least three to four drainage holes at the bottom.
Calendula do not loves wet soil, hence, drainage in the pot should be good to remove excess water, if you want to grow them directly in the ground then choose a spot that is not constantly wet.
You can grow calendulas directly from healthy and disease resistant seeds purchased from the nearest seed house, or you can purchase healthy seedlings from the nearest plant nursery and transplant them in your garden to make it more beautiful.

- Fill this container with germination potting mix and leave some space at the top for watering purposes.
- Water gently before sowing of the seeds, and after watering broadcast the seeds in the growing container. In germination tray sow 2 to 3 seeds in each case.
- Cover seeds with very thin layer of potting mix, and apply water gently so that the seeds do not gets disturbed. Place the germination container in semi-shade, and keep checking for the moisture in the soil regularly.
- Whenever you notice that the top layer of the soil is dry then apply a little amount of water that is enough to moist the soil. Do not overwater!
Within 5 to 7 days you will notice seeds sprouting and new baby seedlings coming out of the soil. You can now place your germination pot under direct sunlight.
You can transplant your calendula plant once it has reached 4 to 5 true leaved stage. It will take near about one month time to reach that stage. Once your plants are ready, its transplantation time.
Fill the growing pots with growing potting mix, make sure that drainage holes doesn’t gets blocked and leave one to two inch space at the top for watering and fertilizer application purposes.
With the help of a gardening tool like trovel or with your hands take out seedlings from the germination pot very carefully without damaging the plant and the roots, dig a hole in the centre of the growing pot that is enough to hold the roots.
Place the roots in the hole, and cover around the base with soil. Gently apply pressure around the base of the plant to fix it properly in the pot. Apply water gently and place your pot in semi shade for 2 to 4 days.

Calendula can grow well if you will place your pot in the region that receives 4 to 6 hours of direct bright sunlight daily, but this plant doesn’t love hot weather or temperature. So prevent your plant during hotter days by placing it under shade.
You need to water this plant frequently whenever you notice that the top layer of the soil is dry during very early stages of the growth for this plant. Once your plant gets very well established then you will not need to worry about watering much.

You should not add inorganic or nitrogen rich fertilizers in this plant as it doesn’t require much care to grow and prosper. Adding heavy amount of fertilizer can seriously damage this plant.
