In the cultivation of iris, the main method of propagation is sowing. When sowing, because the best temperature of seed germination is about 20 ℃, and germination takes about 10 days, about 15 weeks to bloom. So when sowing, we can take the way of batch sowing to meet the needs of viewing.
Basically, butterfly can be sown in spring or autumn. In some areas, the temperature is higher in winter, and cooler in summer, butterfly can be sown all year round
However, the spring sowing of butterfly flowers is not as good as the autumn sowing of butterfly flowers, because butterfly flowers are not heat-resistant, spring sowing needs to go through summer, and autumn sowing does not need. So in some hot summer places, autumn sowing will be adopted.
In general, the spring butterfly will bloom from July to September, the summer butterfly will bloom from September to November, and the autumn butterfly will bloom from February to April of the next year.
When butterfly flowers start to grow, they need to be properly maintained. When the seedlings grow, they can be transplanted. When the plants can be planted, they can choose pot or ground
When sowing, we must be timely, not too early or too late, so as not to affect flowering. When selecting seeds, it is better to first mature those seeds, and then harvest them when the peel of the fruit begins to turn white. In order to maintain the variety characteristics of iris, it is necessary to keep a proper distance between different varieties when breeding.
