Summer Management of Lily
Lily variety, flower shape large and shaped like a trumpet, but also because of its name implies "a hundred years of good harmony","Pepsi heart" meaning and widely loved by people. Summer is the main florescence and dormancy period of lily, so its conservation and management are very important at this time.
Cool down and avoid the sun. Lily growth temperature is 15℃ to 25℃, in this temperature can maintain good growth and flowering. When flowering, the pot plants can be moved to a cool place, or shade the plants, and strengthen ventilation and cooling, which is conducive to prolonging flowering. Lily bulbs are not resistant to high temperatures. When summer heat comes, try to reduce the temperature of the soil. Sawdust, broken grass, leaves, etc. can be used to cover the surface of the pot to cool down.
Dormancy management. When the temperature is higher than 30℃, lily will gradually enter dormancy, stem and leaf gradually withered. When it enters dormancy completely, the withered stems and leaves on the ground should be cut off to keep the soil dry. If conditions permit, lily bulbs can be dug out, buried in moist dry peat soil, stored at low temperatures, and replanted in autumn.
Water and fertilize. Early summer is the peak season for lily growth and flowering, so more watering should be done to keep the soil moist. At the same time, 10 times of decomposed liquid fertilizer should be applied once every 10 to 15 days, and 1000 times of potassium dihydrogen phosphate solution should be applied once or twice when buds appear. After flowering, 10 times of decomposed liquid fertilizer is applied and 500 times of potassium dihydrogen phosphate solution is mixed for 2 to 3 times. When lily begins to enter dormancy, water supply should be reduced to make the soil slightly wet to promote dormancy.
Set up a frame to prevent folding. Some lilies bloom large and many, stems are relatively thin, bamboo sticks or iron wire can be used to set up a stent fixed to prevent flower stems from breaking.

Leaf blight of lily
Lily is native to the eastern and central regions of China. More hardy, like strong light, not resistant to shade. Lack of light can affect growth and flowering. It is suitable for sandy loam with good drainage and rich organic matter. Poor disease resistance, susceptible to disease in a high-temperature and humid environment. The lily plant is upright and upright, the flower is big and colorful, and there are many varieties, which are suitable to form a piece or cluster dotted with the edge of the grass or form a flower border, which is quiet and harmonious. Lilies are also treasures of potted and cut flowers. Lily leaf blight, also known as lily gray mold, affects plant photosynthesis, hinders growth and reduces ornamental value.
