How to propagate Michaelmas daisy? Detailed explanation of propagation methods and precautions
Michaelmas daisy is a perennial flower of the genus Aster in the Asteraceae family. It is a relatively common ornamental plant for laying out flower beds and flower borders, and many flower enthusiasts also like to grow Michaelmas daisy as potted plants. After growing Michaelmas daisy, some flower enthusiasts want to propagate it themselves. So which methods should actually be used to propagate Michaelmas daisy, and what should be noted?
Michaelmas daisy
I. Seed propagation
The sowing period is around early March. Sow in pots or in beds in a warm, sunny place in a greenhouse. Under conditions where the room temperature is not lower than about 15°C, complete germination can occur in about 7 days. When the seedlings are about 5 cm tall, transplant them promptly for the first time to prevent leggy growth. You can choose small pots with a diameter of 12 cm or transplant them into beds. In early May, carry out the second transplanting and final planting, planting them into large pots or directly into the ground as needed. For ground planting, control the plant spacing at about 40 cm to facilitate further tillering and proliferation.
II. Tillering propagation
Michaelmas daisy has a very strong tillering ability, and tillered plants can be separated and planted individually. The time for separate planting is generally chosen in early spring after the soil thaws, after the mother plant has just grown clustered leaves. Dig out the overwintered underground roots, cut the original clump into several pieces with a knife, and plant them separately. The survival rate of the tillered seedlings is extremely high. This method can be used to propagate perennial plants in large quantities.
III. Cutting propagation
Perennial plants grow a large number of tiller seedlings after the beginning of spring. You can use a knife to cut off the young tiller seedlings for cuttings. Use plain sand soil or perlite and vermiculite as the substrate, keep the temperature above 20°C, and provide shade or use a full-light misting system to maintain air humidity. Roots can form in about half a month. Rooted plants can be directly planted into pots or beds.
IV. Grafting cultivation
Using wild yellow wormwood as rootstock for grafting cultivation gives relatively good results. The specific method is as follows: At the end of November or the beginning of December, remove the faded flowers from the Michaelmas daisy and repot it with fresh soil. When the outdoor temperature drops to about 5°C, move the pot into a low-temperature greenhouse. It must not be placed in a medium- or high-temperature room, so as to avoid sprouting and stretching, which would make the chrysanthemum seedlings weak and unable to withstand wind. After the Beginning of Spring the following year, move the potted chrysanthemum to a sheltered outdoor place, and around Qingming Festival apply an appropriate amount of thin fertilizer water such as human waste. From the end of April to the end of June, dig up yellow wormwood seedlings from the wild and plant them in clay pots with a diameter of 5 cun or 7 cun. In June and July, depending on the growth size of the yellow wormwood plants, transfer them to 8-10 cun clay pots, and apply thin fertilizer water once every 5 days. When the yellow wormwood stem height reaches 15 cm, Michaelmas daisy can be grafted onto it using the cleft grafting method. After grafting, cover with a small plastic bag to retain moisture, and it can survive in about 7 days. It should be noted that the height of the rootstock is preferably about 15 cm. If it exceeds 20 cm, the Michaelmas daisy will later feel top-heavy and the stem will be unstable. Secondly, if the inner core of the grafting wound on the yellow wormwood rootstock has already turned white and aged, it is not suitable for grafting, because it is not easy to survive after grafting, and even if it survives, the scion will become rigid and not grow. After the Michaelmas daisy graft survives, thin fertilizer water can be applied frequently, and management is the same as cultivating autumn chrysanthemums. Normally, Michaelmas daisy can be pinched in a targeted way into shapes such as spherical or flat steamed-bun shape, but the last pinching needs to be done simultaneously for each head. If flowering is desired for National Day, the last pinching can be done at Minor Heat (early July). If flowering is desired during the autumn chrysanthemum exhibition, the last pinching can be done in late July.

The propagation methods of Michaelmas daisy are mainly seed propagation, cutting propagation, grafting propagation and tillering propagation. The commonly used methods are seed propagation and tillering propagation.
Precautions for cultivating Michaelmas daisy
Pests and diseases
During growth, Michaelmas daisy can be infected by many pests and diseases, including powdery mildew, mosaic disease and rust, and can also be damaged by pests such as aphids. Once Michaelmas daisy is found to be infected by pests or diseases, timely treatment is needed, spraying pesticides, and during cultivation attention should be paid to ventilation and humidity control.
Pruning
Michaelmas daisy is relatively tolerant of pruning. During growth, timely pruning can make Michaelmas daisy branch more and bloom more.
Leggy growth
In order to make Michaelmas daisy bloom more and grow vigorously, the supply of water and fertilizer needs to be maintained, but if there is too much water and fertilizer, leggy growth may occur, so watering and fertilizing should be reasonable.
