How do azaleas sow and reproduce?

Sowing is sexual reproduction. As the seed setting rate of natural hybridization is very low, artificial pollination is generally needed to improve the seed setting rate of rhododendron and obtain more seeds. Its main method is when the azaleas are in full bloom, choose strong female parents with good growth and beautiful colors, move to the greenhouse, leave 3-4 flowers with large flowers and early flowering in each pot, pick the stamens and new buds near the flowers, and concentrate nutrients. When mucus appears on the head of the style, just use a new brush to dip the pollen of the male parent and apply it for a few times. A week after pollination, the flowerpot was moved outdoors to strengthen the management of water and fertilizer. After about 5-6 months of growth and development, the fruit gradually changed from cyan to brown and the seeds matured in 11-12 months. Immediately pick it, let it dry, clean, and put it in a cool and ventilated place.

Rhododendron seeds are very small and should not be stored for a long time, otherwise the germination rate is low. If evergreen cuckoo seeds should be sown with picking and sowing in pots in the greenhouse, deciduous rhododendron seeds can be sown until next spring.

The sowing basin should be a shallow tile basin, sowing soil, you can dig the loose topsoil with moss on the surface of the sunny hillside, pick up the stone grains, spray it with 40% formalin and 100 times water diluent, disinfect it, and then dry it. It can also be steamed in steam for 15-25 minutes for disinfection, then bask in the sun until half dry and ready for use. Before sowing, first pour the tide in the shallow basin, put a layer of charcoal shavings of about 2 centimeters at the bottom, and then spread a layer of sterilized soil 5-6 centimeters thick, scrape flat, slightly compact, and then evenly divide the seeds above, gently press them, and do not spray water with a spray pot. It is best to use the method of soaking the basin and sitting on water. Cover it with a piece of glass and move it to the greenhouse. When the surface of the basin soil is dry, you can spray some water foggy, but do not spray too much, always keep the basin soil moist.

After sowing, it can germinate after 5-6 weeks. When the seedlings grow out of 2-3 true leaves, they can be gently sandwiched out with small bamboo slices and planted in another pot. Do not plant too densely, but sparsely. After planting, use Reed mats and other shade. Do not let the sun shine directly or let Rain Water get drenched. When the seedlings are young and tender, do not apply fertilizer, wait until the next year when the seedlings grow to nearly 10 cm high, and then begin to apply thin fertilizer; generally, from the end of the second spring to early autumn, individual plants can be planted separately. By the third year, when the seedlings grow to 20 cm high, if they sprout well, a few seedlings will be able to produce flowers.
