How to plant marigolds
Sharing with everyone the related content about how to plant marigolds and the planting methods and timing of marigold seeds in the field of green plants. Next, the editor will introduce.
Marigold seedling propagation
1. Sowing time: The end of September is suitable for sowing marigold seeds. Preparing the soil by sunbathing for a few days in advance can help kill germs and is more conducive to the growth of marigolds.
2. Seed treatment: Soak seeds in warm water for 3 to 10 hours to promote germination until the seeds absorb water and expand, which helps germination.
3. Sowing method: Marigold seeds are too small and can be planted with the help of a toothpick. Wet one end of the toothpick with water and plant the seeds one by one in the matrix. Do not plant too deep; slightly cover with soil.
4. Soaking pot: Place the pot with planted flower seeds in water, filling it to 1/2 to 2/3 of the pot's height, allowing the water to slowly rise.
5. Maintenance: Before the cold wave and low temperature arrive, wrap the pot with a plastic bag to keep it warm and moist. After the seedlings emerge, uncover the film. After sowing in autumn, to avoid attacks from cold waves and low temperatures, you can wrap the pot with a plastic bag to keep it warm and moist. After the seedlings emerge, uncover the film and expose them to sunlight before 9 a.m. or after 3 p.m.
6. Seedling propagation: After the seeds have fully germinated, remove the weak seedlings and maintain the same spacing between each plant. When the seedlings have grown more than three leaves, they can be transplanted.
Marigold cultivation methods
1. Shading in spring, summer, and autumn: Marigolds cannot be exposed to strong sunlight and need timely shading in the three seasons. When the outdoor temperature exceeds 25°C, keep it indoors or shaded.
2. Sufficient light in winter: In winter, because the temperature is not high, direct sunlight can promote photosynthesis, which is beneficial for marigolds to form flower buds, bloom, and bear fruit.
3. Shading after flowering: After flowering, place the plant indoors for 10 to 15 days, then move it to a shaded outdoor environment for one month. This alternating care helps accumulate nutrients in the plant, extending the blooming period.
4. Marigolds prefer warm climates and are afraid of extreme heat. Growth may be poor when the temperature exceeds 34°C in summer.
5. Not frost-tolerant, marigolds may enter dormancy or even die when the temperature is below 4°C in winter.
6. Pinching and pruning: Cut off branches with old and yellow leaves every two months. As long as the temperature is suitable, they can bloom all year round.
7. Humidity: Water 1 to 3 times a day, increase the number of waterings on sunny days, and reduce them on rainy and cold days. Do not overwater and ensure the water is clean.
Marigold cutting methods
1. Branch selection: Usually combined with pinching work, cut off the thicker, disease-free top branches as cuttings and plant them directly.
2. Cutting matrix selection: Choose materials such as nutrient soil, river sand, or peat soil. Due to the limitations of home conditions, it is difficult to get ideal soil, so slightly coarser sand can be used, but it should be rinsed with clean water before use to avoid germs.
3. Cutting: When the branches and soil are ready, insert the branches directly into the soil.
4. Management after cutting: Control the temperature at 18 to 25°C after cutting and spray water 1 to 3 times a day. During maintenance, block 50% to 80% of the sunlight until the roots grow, then move them to a shaded area.
5. Transplanting: When potting the seedlings, first place a 2 to 2 cm thick layer of coarse particle matrix at the bottom of the pot, then sprinkle a layer of organic fertilizer, followed by a layer of matrix, and then place the plant.
Marigold pinching methods
1. Generally, two pinching operations are performed before flowering to promote the growth of more flowering branches.
2. One to two weeks after potting, remove the top and retain 3 to 4 leaves at the bottom to promote branching.
3. Three to five weeks after pinching, you can perform the second pinching. Remove the top of the lateral branches and retain 4 leaves below.
4. After two pinching operations, the plant shape will be more ideal, and the number of flowers will also increase.
