Planting marigolds for seedlings

Marigolds are herbaceous plants. There are approximately 30 types marigolds. However, all species are unpretentious in care, grow quite quickly, can easily withstand drought, and love warmth and light.
Marigold reproduce by seeds, which can be sown directly into open ground in early summer. But it is best to grow seedlings in greenhouse conditions, and only then plant them in open ground.
Planting marigolds for seedlings at home should be carried out in early or mid-spring. For any type of marigold it is necessary nutritious soil, constant temperature ranging from 18 to 20 degrees, as well as moderate watering especially at the initial stage of growing seedlings.
For indoor growing, pots or boxes with several holes are suitable. Must be at the bottom drainage about three centimeters thick. The top layer of soil must be made loose for air supply.
It is best to sow sprouted seeds, carefully placing them in prepared grooves at a distance of about one centimeter and covering them with a layer of earth about one and a half centimeters thick. Planting marigold seedlings does not end there. The necessary conditions are sufficient light and moisture, and maintaining moderate temperature conditions.
Marigold sprouts should appear after 3-5 days. If the seedlings are sitting too densely, then it is necessary to picking.
Ready seedlings are planted in an open area only late May - early June.
