How does Spiraea cantonensis propagate? Introduction to common propagation methods
Spiraea cantonensis is not difficult to cultivate and is very suitable for ornamental use in gardens. During its full blooming period, the profusion of small white flowers covers the branches, making it very beautiful. Artificial propagation of Spiraea cantonensis can be done by sowing, cuttings and division. Here is a brief introduction to the propagation methods of Spiraea cantonensis.
Spiraea cantonensis
Sowing:Can be sown in spring or autumn. After the seeds are harvested, store them in sand over winter, sow in March to April in spring, and they will germinate after 25 to 30 days.
Cuttings:Carry out in June to July during the plum rain season. Cut semi-lignified branches, 8 to 10 cm long, keep 2 to 3 leaves at the upper end, insert into a sand bed, and they will root in 25 to 30 days; cuttings from dormant branches are taken in mid to late February.
Division:In early spring from February to March, carry out division together with transplanting. Cut apart the suckering shoots growing beside the mother plant, shorten them appropriately, and replant separately.
Spiraea cantonensis cultivation methods and Spiraea cantonensis propagation methods
Spiraea cantonensis has dense inflorescences and pure white flowers, and is very beautiful. Because its flowers are delicate and eye-catching, Spiraea can also be used for cut flower production. So how do you grow Spiraea cantonensis? What propagation methods are there? Let's learn about it together with Xiao Qi.
I. Spiraea cantonensis cultivation methods
1. Planting: Can be done in both spring and autumn. Generally, ground planting for ornamental purposes is the main method. Choose a spot with sufficient sunlight and good ventilation; digging a hole and dipping the roots in slurry before planting gives a higher survival rate. It grows poorly in shady environments.
2. Light and temperature: It can overwinter in the open field. It grows and develops well under conditions of sufficient light and a temperature of 20-25°C. When the winter temperature drops below -25°C, frost damage will occur, and it may even die.
3. Watering and fertilizing: Apply sufficient base fertilizer before planting, generally decomposed manure; dig the planting hole deeply. Apply phosphorus and potassium fertilizer (monopotassium phosphate) 2-3 times during the flowering period, and apply 1 wintering fertilizer at the end of autumn, preferably decomposed manure or barnyard manure. Stop fertilizing in winter and reduce watering.
4. Shaping and pruning: Best done in spring. Before budding in early spring, cut off dead branches, overly dense branches, diseased and weak branches, and aged branches, so that the plant shape is attractive, with abundant flowers and lush leaves, and the plant grows vigorously.
5. Pest and disease control: When Spiraea is cultivated in nursery fields, it has strong resistance and few pests and diseases, and no serious diseases have occurred. However, after heavy rain, if there is too much standing water on the ground and the roots are waterlogged for a long time, root rot is easily caused. Drain promptly, and for diseased plants, use 1000 times mancozeb or 800 times chlorothalonil to drench the roots and spray the leaves three times, after which the symptoms will disappear.

1. Propagation by sowing: Soak the seeds in warm water (30°C) for 1 day and night, take them out and place them in a petri dish lined with moist filter paper. In a room at 18-20°C, they will begin to germinate in 8-10 days, and germination will finish in about 10 days, with a germination rate of 80%-95%. When the seeds mature in early summer and the weather is relatively dry, they can be sown immediately after collection, either in pots or in the open field. Sowing Spiraea under the mother tree to create moderate shade is beneficial for seed germination and faster initial seedling growth, and can increase the seedling emergence rate and the rate of seedlings reaching plantable size.
2. Propagation by cuttings: Use hardwood cuttings in spring, and softwood cuttings in summer. Use pruning shears to cut 1-2 day old cuttings, 10-15 cm long, soak them in TianBT rooting powder for 1 day and night, and after inserting them, shade with a sunshade net and mist to keep the seedbed moist, with a survival rate of over 95%. Spiraea plants have strong suckering ability, so they can also be propagated by division, preferably carried out from October to December each year.
