In summer, the temperature is very high, at this time, the plant of Begonia Rieger will be in a state of growth stagnation, dormancy or semi dormancy.
In summer, we should cut off the flowers and dead leaves for Rieger Begonia and shade them in time. In addition, the watering should be controlled to avoid the rotten roots caused by water accumulation in the flowerpot. Fertilization should stop
Autumn will come after summer, when the temperature begins to drop and the plant begins to sprout new branches. When the Begonia grows to a certain height, it can be pruned to cut off the old branches. When the new branches grow to a certain height, keep 3 branches, and the remaining branches can be cut off, so as to make their nutrients more concentrated.
In October, the growth rate of Rieger's Begonia plants will be accelerated. At this time, the soil needs to be kept moist and liquid fertilizer needs to be applied every half month.
In winter, we need to ensure that Rieger Begonia has enough light, and the curing temperature should be kept above 10 ℃.
When breeding Rieger Begonia, it should be noted that during the vegetative growth period of Rieger Begonia, the light needs to be maintained for more than 14 hours, while the time of flower bud differentiation is less than 10 hours, which is conducive to flower bud differentiation. When the plant grows, when there are 4 leaves, the heart can be removed.
