For plants with blue flowers, people who like to raise flowers are not strangers, especially blue snowflakes that bloom a lot and bloom continuously, which are almost flowering machines. The blooming period of blue snowflakes is different from many plants, and it chooses a hot summer. Its blue flowers bring a hint of coolness to people who endure the hot summer. Therefore, many people have its presence on the balcony or in the courtyard.
Growth habits
Blue snowflakes are a genus of perennial upright herbs in the family Lamiaceae. It also has a longer flowering period, generally from May to September. Blue snowflakes like a warm environment, have a strong heat resistance, like light, but can not be exposed to strong light, after long-term exposure, the leaves will be sunburned and scorched. It can also tolerate shade, especially in the hot summer, proper shade, there is better astigmatism will grow better, and more flowers will bloom.
What conditions are needed for flowering?
1. Lighting
Blue snowflakes blossom more is the most attractive place, if you raise their own blue snowflakes, less flowering, should be some conditions are not met. The first is the problem of light, if you want it to blossom more, you must meet sufficient light requirements. If it is planted on the balcony, it can be placed in a position with good light, and if it is planted in the south, it can be properly planted in a better astigmatism position. Although it can accept strong light, it cannot be exposed to strong light for a long time, especially in the southern summer, the weather is hot, the high temperature is often more than 35, and the autumn "autumn tiger". Strong light exposure can easily lead to sunburn of leaves and flowers, coupled with exposure to sometimes heavy rain, it is easy to cause black rot of flowers. Black rot can easily spread throughout the plant if not treated in time.
2. Water
In terms of watering, we should also pay attention to it, and try to choose sunny days to water. Blue snowflakes in full bloom, flower buds and flowers are more, if the weather is not good, or the water stays on the flowers for too long, it is easy to cause black rot, at this time it is necessary to clean up the black rot part in time, if it spreads to part of the plant, it is also necessary to prune it in time.
3. Ventilation
Another important thing is that ventilation should be good, and it is difficult to raise blue snowflakes without ventilation. So if it is maintained on the balcony, it is necessary to put it in a better position of light, but also to ensure ventilation, otherwise the buds of blue snowflakes are easy to fall, and the leaves will also appear yellow, which may be contrary to your original intention of maintaining it.
4. Fertilize
Blue snowflakes have another to keep up with, and that is fertilizer. There are a lot of people who say how to fertilize? Which fertilizers to apply. If you really don't understand, you can buy some organic fertilizer, it contains more elements, and there is another is to buy some compound fertilizer, added every ten days and half a month, nutrients are enough, equivalent to its cornerstone is stable, flowering will naturally become more.
5. Trim
Blue snowflakes should be pruned appropriately to a certain extent, because the flower bulbs of blue snowflakes are mainly concentrated at the top of new branches. Long-term non-pruning, are some old branches, it is not very fond of flowering, so it is very necessary to prune it, especially after flowering, after pruning will germinate new branches from the side of the old branches, which will make the blue snowflakes flowering ability doubled. At the same time, a pot should not be planted with too many blue snowflakes, if too much, the pot should be changed in the later stage, or the seedlings should be transferred to increase its growth space.
