How to grow marigold: planting and care
Sowing thecalendulait can start in spring. The ideal seedbed should consist of three parts of fertile soil and one of coarse sand, but a universal soil for sowing or soft soil will also do.
Since the seeds are extremely small, it will not be possible to bury them individually: once placed on the seedbed, just bury them by pushing them under the ground with a flat piece of wood.
Once the seeds have been added, moisten the soil by spraying the water with a nebulizer (a spray bottle such as that of glass cleaning detergents will suffice) and cover the seedbed with a plastic sheet or a glass plate. The seedbed should be kept indoors, in the shade, in a place where the temperature is constant and around 15 ° C. Every day, open the tray to remove condensation from the plastic.
THE marigold seeds they germinate in about 2 weeks, at the time of germination, remove the cover (plastic or glass) and thin out the shoots by eliminating the most fragile and small ones. Transfer the seedbed to a brighter position (in partial shade) and when the young plants are large enough, transplant them into single pots.
Those who intend to sow marigold directly in the flower bed will have to work the soil well by raking it and making it as soft as possible. Arrange the seeds so that you can get 5 - 8 plants per square meter. If you insert more plants per square meter, thecalendulait will thrive anyway but will give less abundant blooms.
