How to propagate marigolds

Seed propagation

Marigolds are generally propagated by sowing.

Marigold seeds are easy to germinate and are generally sown in late March to early April in spring. Plant the marigold seeds in the culture soil, you can choose to use a sowing pot. After sowing, ensure the temperature is between 15 and 20 degrees Celsius, and seedlings will generally emerge in a week.

Allow the marigold seedlings to continue growing after they emerge. When the marigold seedlings grow to 5 cm and have 7 to 8 leaves, they can be transplanted and planted.

When sowing and propagating marigolds, a certain temperature must be maintained. After sowing, the soil must be covered and watered to ensure sufficient moisture. It takes about 50 days from sowing to flowering. If it is propagated by sowing in summer, it will take 60 days for it to bloom. When selecting seeds, choose the fruits that are produced after flowering in autumn, which should be fresh and shiny. Because the germination rate of seeds produced by summer flowering is low.

Cutting propagation

The cutting propagation of marigold is carried out in summer from May to June.

Take young branches about 10 cm long as cuttings, cut them, remove the lower leaves, and insert them into sand or vermiculite. After marigold cuttings, water it sufficiently and provide shade. It will generally take about 10 days for it to take root and can be transplanted after taking root.

Marigold is relatively easy to manage after transplanting. Generally, after transplanting, the marigold should be gradually moved to a sunny place for daily management, and it will bloom after about 1 month. During the period from planting to flowering of marigolds, you can fertilize them once every 20 days. You need to apply thin and well-rotted liquid fertilizer to ensure that the soil is fertile. Water appropriately to keep the soil slightly moist. You can pinch the tops several times to increase branches and encourage more marigolds to bloom.
