Propagation methods for the dawn redwood
There are mainly two propagation methods for the dawn redwood: one is propagation by sowing and the other is propagation by cuttings.
Sowing propagation of the dawn redwood
In sowing propagation, the dawn redwood begins to bear fruit relatively late; generally only large dawn redwood trees over 10 years old begin to produce flower buds, and the seeds the dawn redwood produces are mostly shriveled.
Sowing of the dawn redwood is usually carried out in mid-to-late March, and seeds are mostly obtained from mother dawn redwood trees in the tree's place of origin. The germination rate of dawn redwood seeds is only about 8%. The seedlings are slender and weak, and they fear drought and are afraid of waterlogging, so soil that is level and easy to drain and irrigate should be chosen.
Cutting propagation of the dawn redwood
Because dawn redwood seed sources are scarce and the seed survival rate is low, propagating dawn redwood by cuttings is still relatively common. Dawn redwood cuttings can be taken in spring, summer and autumn, with spring cuttings being the main ones. It is best to choose a mother plant propagated from seed as the mother tree for collecting cuttings. Take cuttings from the current-year branches of 1-3 year old seedlings; these root early and give a high cutting survival rate. Dawn redwood cuttings are further divided into hardwood cuttings and softwood cuttings.
1. For hardwood cuttings of the dawn redwood, early-to-mid March is suitable in the Jiangnan region. Before cutting, it is best to use a substance to promote rooting. After spring cuttings, shade is mostly provided.
2. Softwood cuttings of the dawn redwood are taken from late May to early June and require careful management, with a double-layer shade frame. Autumn cuttings are taken in September, using semi-mature branches; they root in the same year but do not send out shoots, and a single-layer shade frame is needed.
Placement methods for dawn redwood bonsai
1. Dawn redwood bonsai is usually placed at one side of the living room, implying wealth and prosperity. It can also be placed in the study. It is best not to place it in the bedroom, because plants all belong to the yin principle in the five elements.
2. The placement position should not form a straight line with the kitchen. The kitchen belongs to fire in the five elements, while bonsai all belong to the yin principle, so this could very likely cause the bonsai to wither and turn yellow.
3. If you are very particular about feng shui and the five elements, it is best to place the dawn redwood bonsai according to your own five elements, and judge the suitable direction and position for the dawn redwood bonsai according to your five-element zodiac sign.
4. As a plant bonsai, when placing the dawn redwood bonsai avoid placing a single specimen, because this forms the character "" (trapped) within the house, so placing a single tree in the house is not appropriate.
5. If the dawn redwood bonsai you choose is relatively small, then pay attention that its placement does not block the family's activities, and also avoid disorder. At the same time, pay attention to pruning and care for the bonsai, because to a certain extent its feng shui and beautiful leaf shape can affect the family's fortune and prospects.

[Common questions] Propagation methods for the dawn redwood
[Expert answer]
1. Propagation by sowing
Collect the seeds as soon as the cones mature, sun-dry them, sieve out the seeds and store them dry. Sow in March in spring. The sowing rate is 0.75-1.5 kg per mu, using drilling (row spacing 20-25 cm) or broadcasting; after sowing, cover with grass, not too thick, and keep the soil constantly moist.
2. Propagation by cuttings
Either hardwood cuttings or softwood cuttings can be used.
3. Hardwood cuttings
Selection of mother trees for cuttings: cut 1-year-old vigorous branches from 2-3 year old mother trees as cuttings.
Time for collecting cuttings and taking cuttings: collect cuttings in January, and take cuttings around March 10.
Cutting specifications and treatment: cut the cuttings to a length of 10-15 cm, then tie them in bundles of 100 and insert them in sandy soil to soften, keeping them warm and moist and protected from freezing. Before cutting, soak them for 10-20 h in a solution of ABT No. 1 rooting powder at a concentration of 100 mg/L.
Post-cutting management and cutting method: use field cuttings, 20,000-30,000 plants per mu; after cutting, use full-light seedling cultivation, watering, weeding and loosening the soil at the right times.
Results: branches soaked in ABT rooting powder rooted 15-20 days earlier, with more and thicker roots, and a survival rate of over 90%, about 35% higher than others not treated with ABT rooting powder.
4. Softwood cuttings
Carry out from late May to early June. Choose semi-lignified soft branches as cuttings, 14-18 cm long, keep the top shoot and the upper 4-5 pinnate leaves, insert 4-6 cm into the soil, and plant 70,000-80,000 per mu. After cutting, shade and mist 3-5 times a day. After late September the shade frame can be removed. Keep the nursery land constantly moist and ventilated, which can promote the cuttings to root sooner. During the seedling stage, pay attention to controlling damping-off and stem rot.
