When does butterfly plum blossom? What if it doesn't blossom?

Butterfly plum belongs to the family Viola, which is a common perennial herbaceous flower, which is mostly cultivated for 2 years. Usually each flower is (or purple), yellow and white, so its scientific name is pansy. The flowers of butterfly plum are symmetrical on both sides, and the petals below have a distance stretching backwards. The whole flower resembles a butterfly that spreads its wings. Potted plants are placed indoors, with cold spring outside, colorful butterflies flying indoors, and infinite spring light, which can not help reminiscent of plum blossoms in the wind and snow. Hence the beautiful name of butterfly plum.

Butterfly plum likes loose and fertile sandy loam with good growth and development, leaves and flowers are numerous, such as planted in barren or poorly drained soil, the plant is short and thin, underdeveloped, and the variety is degraded. Therefore, no matter sowing or cultivating, it is declared to use loose and fertile garden soil as basin soil. So, what if the butterfly plum does not blossom in the process of pot conservation?

When does butterfly plum blossom?

Butterfly plum blossoms early, the florescence is long, when the flowers are in full bloom, bright colors, shaped like butterflies, is the main decorative material of the flower bed in spring and autumn. The time depends on the time of flowering, sowing in March-April in spring, flowering in June-October, poor development, small flowers and sparse flowers. Sowing from September to October in autumn, flowering from February to March in the second year, with long flowering period, large flowers and many flowers.

Why doesn't butterfly plum blossom?

People who cultivate ornamental flowers and trees all look forward to many flowers, big flowers and beautiful colors. But in practice, some flowers and plants grow luxuriantly but do not blossom, some blossom but the flowers are small and light, and some even always fall flowers, buds and flowers wither before they bloom. The author believes that these phenomena are mainly related to the following five factors.

1. Physiological factors

Butterfly plum belongs to the type of flower bud differentiation in winter and spring, which is carried out once a year when the temperature is low in winter and spring, and its flowering period is short and continuous. In the period of flower bud differentiation, the conditions of its growth and development should be met to ensure the smooth progress of flower bud differentiation in order to make the flowers colorful.

2. Water and fertilizer factors

During the period of flower growth, excessive water and fertilizer can easily cause branches and leaves to grow, and nutrients are mostly used for the growth of roots, stems and leaves, which affect the formation of flower buds, resulting in non-flowering or few flowering, even if they can blossom.

If partial application of nitrogen fertilizer, lack of phosphorus and potassium fertilizer, but also affect flower bud formation. Therefore, in the period of flower bud differentiation, attention should be paid to the application of fertilizer containing phosphorus and potassium, or spraying 0.3% potassium dihydrogen phosphate solution, which is beneficial to flower bud formation and bud formation. Excessive fertilization during pregnancy, watering suddenly more and less, it is very easy to cause falling flowers and buds. During the flower growing period, lack of fertilizer and water and poor plant growth can easily lead to less flowering or poor flower quality.

3. Temperature factor

The leaf bud of Prunus mume is very sensitive to the environment before it changes to flower bud. As it is a winter flower, it requires a low temperature of 0 ℃ ~ 10 ℃ and 30 ~ 70 days to complete induction, such as biennial grass flowers and perennial flowers that bloom in early spring. In flower cultivation, the conditions of flower induction should be satisfied as far as possible to promote the transformation from leaf bud to flower bud.

4. Soil factors

Most flowers like acid soil or neutral soil, afraid of salt and alkali, even if it is alkali-tolerant soil, the ph value of flower soil can only be about 7.5. If the alkalinity of planting butterfly plum is too high, their development and flowering will be affected.

5. Insertion factor

The choice of branches for cuttings is also the key to flowering. Cuttings for asexual reproduction, grafting or air crimping must be intercepted from the tree-carrying parts of adult mother trees that enter the reproductive stage. These branches are reproductive branches, and such cuttings are used to propagate new seedlings and seedlings can blossom in the same year. If the vegetative growth branch cuttage is used, although the new plant grows healthily, there is no flower to bloom in that year, because it does not have reproductive genes and cannot differentiate flower buds.
