What are the cutting propagation methods and precautions for marigolds?

Marigold symbolizes longevity, and its flower language is sweet love, health and longevity, and so on. Many friends can clearly identify marigolds, and now quite a few friends also grow potted marigolds for ornamental purposes. Generally, marigolds are propagated by cuttings, so the editor will introduce the precautions for marigold cutting propagation.

Marigold

1. Prepare the soil. The substrate used for marigolds is 40% rice husk ash and 60% river sand. Rice husk ash is not only loose and well-draining, but also effectively prevents the cuttings from rotting. After mixing the substrate well, spray an appropriate amount of water so that the substrate moisture content reaches about 60%, and use it 1 hour after spraying.

2. Cuttings. Marigold cuttings generally keep 3 to 5 nodes, with or without terminal buds. The leaves at the base of the cuttings must be trimmed clean to avoid excessive water loss. When trimming, the wound must be smooth; cut the lower wound of the cutting at a 45-degree angle and cut the upper wound straight across.

3. Cutting insertion. First use a small wooden stick the size of the cutting to make holes in the substrate, with a plant spacing of 3 cm and a row spacing of 5 cm. Gently insert the cutting into the pre-made hole to a depth of 1/3 of the cutting, and use your index finger and thumb to lightly press the sand around the cutting firm.

4. Management. After inserting the cuttings, use a sprayer to moisten the leaves; too much water can easily cause the cuttings to rot. Then cover with a shade net at a height of 80 cm above. After that, spray mist once each day at around 10 a.m. and 5 p.m., just enough to moisten the leaves. The place where the cutting tray is placed must not be exposed to rain or the western sun, otherwise all previous efforts will be wasted. If the density of the shade net is not too high, it is best to cover with two layers of shade net.

How to propagate marigolds: sowing and cutting propagation methods

Marigold sowing is generally carried out from late March to early April each year.

The soil for sowing marigolds is generally vermiculite or a prepared nutrient soil, and the soil must be disinfected.

Scatter the seeds on the soil, and after sowing cover the seeds with vermiculite. Be sure to maintain substrate moisture, and at the same time carry out short-day treatment for 14 days. The optimal temperature for seed germination is 17-20 degrees Celsius, and all seedlings emerge within 5-8 days.

After the seeds emerge, gradually increase light, spray with a fine-nozzle watering can, and ensure substrate moisture. When the seedlings produce 3 true leaves, transplant them once, moving the seedlings into bull's-eye pots filled with No. 1 culture soil, 1 seedling per pot. After potting, water thoroughly, allow about 5 days for seedling recovery, gradually increase light, and carry out normal seedling management.

Cutting propagation is best carried out from May to June each year. It roots very easily. Choose tender branches as cuttings, about 10 cm in length is sufficient. Insert them into a sand bed or peat soil, keeping the room temperature at about 19 degrees Celsius to 21 degrees Celsius. After insertion, they generally root in 10-15 days, and cutting seedlings generally bloom in 30-40 days.

Is marigold poisonous? Marigold propagation methods

Marigold, which carries an auspicious meaning, has long been regarded as the flower of respect for the elderly. Many friends worry that marigold is poisonous, so is marigold actually poisonous? Let's take a look at the answer below, as well as the propagation methods of marigold.

Is marigold poisonous?

Marigold is non-toxic. Marigold is not only non-toxic, but can also detoxify. In particular, it is rich in lutein, which can both provide antioxidant effects and supply beneficial pigment to the macular area of the eyes, filter blue light, and help improve eyesight and clear heat.

Marigold propagation methods:

Marigold propagation methods mainly include sowing and cutting propagation.

(1) Sowing propagation: the sowing time is generally chosen between March and April for hotbed sowing. Before sowing, soak the seeds in warm water (water temperature 35-40 degrees C) for 3-4 hours, then remove them and rinse once with clean water. Drain the water and they are ready for sowing. Sowing should be carried out on a windless, sunny day. Level the soil surface of the seedbed and water it thoroughly once; sow after the water has seeped in, then cover with a very thin layer of fine soil. The suitable germination temperature for marigold seeds is about 20 degrees C. After sowing, they can germinate in 4-5 days, and the seedlings emerge quickly from the soil. When the number of true leaves reaches 2-3, 1 transplanting is needed, and in late May they can be planted out in the open field. Generally, they can bloom 70-80 days after sowing. Summer sowing can also be carried out to meet needs during the National Day period; summer-sown marigolds generally bloom in 50-60 days.

(2) Cutting propagation: marigold cutting propagation can be carried out between May and June. Choose tender branches from robust plants free of pests and diseases as cuttings. Cut about 10 cm of tender shoots from the tips of the branches, make holes with a thin wooden stick, insert them into an open-field cutting bed, firm the soil, and build a shade shed for shading. Maintain soil and air humidity; they can root in about 2 weeks, be ready to leave the nursery in 3 weeks, and bloom in about 35-42 days. Because cutting seedlings have a short growth period, they can bloom while the plants are still relatively short. Their flowering period is easy to control, making them especially suitable for applications such as flowerbed arrangement.
