The planting methods of Begonia are: germination treatment, sowing seeds, and post-sowing management. Begonia care methods are: temperature, light, water, fertilizer, changing pots.
A, begonia planting method
1, germination treatment
In order to improve the germination rate of begonia seeds, you need to germinate the seeds before planting. Specific steps are: first soak the seeds, selected floating bad seeds and empty seeds, and then choose absorbent cotton gauze to cover the seeds, placed in about 15-25 degrees Celsius indoor, in this process need to give the seeds every day to change the water to clean, so as to avoid seed mold, until the seeds reveal the white part of the seed will be sown.
2, sowing
Sow the seeds after germination, cover the soil and water, remember to sow each seed 30 centimeters apart, the white part of the upward, the soil can not be covered too thick, probably cover a centimeter or so can be.
3, after sowing management
Begonia seeds need a lot of water to germinate, so after sowing, watering in time, always ensure that the soil is moist. However, watering should not be overwatered, otherwise it will affect the germination rate and survival rate.
Two, the care of begonias
1, temperature
The most suitable temperature for the growth of begonias in the 15-25 between, the temperature is too low will make the growth of begonias is too slow, and now many places in the temperature is almost all kept at 10 ° or so, can not reach the temperature of the growth of begonias. Begonia growth temperature, even if the temperature is relatively low, but the growth of begonias does not have much impact, long is still long, is slower, with the increase in temperature, the growth of begonias is the more robust, the temperature should not be higher than 28 °, otherwise it is easy to occur disease.
2, light
Begonia is more like the light of the plant, in the spring at noon when the weather is warm, the need to move begonias to the outdoor sun, to the evening when the sun goes down on the need to move begonias indoors, because the night temperature will drop, the spring outdoor temperature is relatively high when the diffused light is certainly also high. So it's important to shade properly when supplementing sunlight outdoors.
3, water
Begonia in the growing process of water requirements are not high, usually watering some of the appropriate watering can be, can not appear the phenomenon of stagnant water, watering to grasp the bad can look at the soil watering, the soil is wet, do not need to water, in the spring there is a cloudy and rainy weather do not try to water, to avoid the loss of water is too slow to lead to root rot. Root rot.
4, fertilizer
Begonia and other flowers of the fertilization method are similar, and in the spring is the peak season of growth of begonias, that fertilizer is certainly essential, not only the peak season of growth, but also during the flowering period should not forget to supplement the fertilizer, if you do not give enough nutrients, even if you hit the buds may not be able to bloom in the peak season of growth needs to be two weeks on a weekly basis, and the blooming period should not be forgotten to add fertilizer, if not given sufficient nutrients, even if you hit the buds can not necessarily bloom. The peak growing season needs to be fertilizer once every two weeks, try not to pour all over the roots, you can dig a circle of pits around the flower roots and bury the fertilizer in it.
5, change the pot
Breeding begonias need to change the pot once a year, the first root growth is too fast, the original pot can not accommodate. Secondly, the soil in the original pot is not enough nutrients to meet the growth of begonias. In the spring can also be given to the begonia pot, pots try to choose a little larger, in the pot before the need to give the begonia pruning, begonia roots and branches are to be pruned, the roots need to cut off the rotten, the leaves to be cut more, diseased branches, dead branches, overlapping branches are to be pruned.
