How to raise potted butterfly flowers

Butterfly, also known as pansy and grimace, is one of the three main grass flowers in spring flower beds in northern China. Butterfly is native to northern Europe and is a kind of violaceae flower like the wild flower Viola in early spring in China. Nowadays, all the popular varieties are artificial hybrids. The butterfly flower was originally a perennial perennial grass flower, but it has become an annual or biennial grass flower after artificial cultivation, which needs to be sowed every year. In the Yangtze River basin, seeds can be sown all the year round and flowers can be used all year round, but they do not grow well in the hot summer.

Butterfly is a common wildflower species in Europe and is often cultivated in parks. It is the national flower of Iceland and Poland. Each flower usually has purple, white and yellow colors, also known as pansy. This species is hardy and likes to be cool, and its flowering is greatly affected by light.

[soil]

The potted soil should be rich in organic matter, or mixed with 30% peat soil, 20% serpent sawdust, 40% loam soil and 10% rotten compost. It is not strict with the soil and can bear poor soil. It is suitable for growing in the soil with loose fertility and rich organic matter, but it is difficult to grow well in the soil with moist and poor drainage.

[temperature]

Butterfly flowers like cold or warm, avoid high temperature and humidity, and the suitable temperature for childbearing is 5-23C. If there is hot and high temperature above 28C, good ventilation should be made to reduce the temperature so as to prevent wilting and death. The temperature is 16 ℃ to 18 ℃ at night and 18 ℃ to 24 ℃ in daytime. It is difficult to maintain the optimal growth conditions when the plant is placed outdoors. The negative temperature difference between day and night helps to make the plant shorter and of high quality. Be careful not to have a high temperature.

[light]

Butterfly flowers like sufficient sunlight, light is an important limiting factor of flowering, sunshine length has a greater effect on flowering than light intensity, poor sunshine, poor flowering, in the process of cultivation, plants should be guaranteed to receive direct sunlight of not less than 4 hours a day. It is sensitive to light, if the light is sufficient and the sunshine time is long, the stem and leaf of butterfly flower will grow luxuriantly and blossom earlier; if the light is insufficient and the sunshine time is short, the flowering of pansy is poor or delayed.

[watering]

Butterfly flowers prefer the soil environment of micro-tide and are not tolerant to drought. Keep the soil moist during the growing period, dry in winter, and see wet every time you are watered. When plants bloom, it is necessary to maintain sufficient water for the increase of flowers and the increase of the number of flowers. We should pay attention to timely watering in the season with high temperature and strong light. Keeping enough water is necessary for the increase of flowers and the number of flowers. But do not water too much, because butterfly flowers grow in cool areas, the water will not give off very quickly, do not need much water.

[fertilization]

During the growth period, topdressing once every 20-30 days, all kinds of organic fertilizers or nitrogen, phosphorus and potassium are good. During the growing period, it is necessary to apply thin fertilizer frequently, loosen the soil, pick the heart, and water normally. On the other hand, in the growing period, fertilizer and water should be applied once every 2 to 3 times, and the concentration is 100~150ppm, mainly compound fertilizer containing calcium. Nitrogen fertilizer is the main fertilizer in the early stage, and phosphorus fertilizer can be increased near flowering stage.

In addition, if there is sufficient light and cool environment during the flowering period, it can continue for a month or two. Picking off the residual flowers in time can prolong the florescence. When the temperature is more than 30 ℃ for several days, it no longer blossoms.

[pruning]

In the growing period, it is necessary to remove the residual branches and flowers in time, control the growth of the overgrown branches by picking the heart, promote the new branches, make the plant complete, have a good crown shape, and prolong the flowering period. Cut off the residual flowers immediately after the flower fade, which can promote the re-flowering, and the temperature is higher after the end of spring, and the flowering is getting smaller and smaller.

[diseases and insect pests]

The main diseases that harm the stem, leaf, flower and root of butterfly are charcoal jaundice, rust, gray mold, root rot and so on. Once the disease occurs, you can spray 500 times 600 times more than 50% carbendazim or 800 times 75% chlorothalonil diluent.
