How to care for the Bleeding heart vine? I believe a lot of people do not know, because it is not long in China's planting time. Now let's learn how to care for Bleeding heart vine.
The cultivation soil is fertile, loose and well-drained sandy loam, and the culture soil or the mixture of peat soil and coarse sand is used for pot cultivation. The commonly used soil formula is 4 parts of humic soil, 4 parts of Garden soil and 2 parts of sandy soil.
It is sensitive to Bleeding heart vine, and needs sufficient water in growing periods. Stem and leaf growth period to keep the saline soil moist, but watering can not be excessive. Water is too large, resulting in only long tendrils and not flowering, even leaves yellow, fall, root rot and death. If the branch withered, stop watering, let it recover, germinating new leaves. In the summer high temperature season, it should be fully watered, appropriate shade. In winter, reduce watering, make it dormant, in order to ensure safety over the winter.
Sufficient sunshine in winter and shade in summer when it is too hot, otherwise the leaves will turn yellow. When the light is insufficient, it can cause Bleeding heart vine not blossom. Flower bud differentiation is not affected by photoperiod, but strong light can promote flower bud differentiation and development. It should not be placed in the dark for too long. At the temperature of 21℃ above, more than 24 hours, it will fall.
Fertilizing should not be too much. Apply fertilizer once every half a month, add potassium phosphate fertilizer once or twice in flowering season, high potassium nitrate fertilizer in four seasons for "hui" 20-8-20, or apply rotten thin baking fertilizer water once every 7-10 days for 3 to 4 times. In winter, reduce watering and stop fertilizing. If yellowing phenomenon is found in the process of caring for Bleeding heart vine, the leaf can be gradually changed from yellow to green by applying topdressing (0.2% ferrous sulfate).
When the cuttings or sowing seedlings grow to 15cm after pot planting, the branches are cut 10cm away from the mouth of the pot to promote the germination of strong new branches. During the growth period, strictly control the height of branches, pay attention to the top to pick the heart, in order to branch neatly, the future flowering densely. In half a month after the heart is picked, the application of Bijiu or Xiaozhuang to control the height of the plant, to achieve plant short, leafy, more flowers.
12 ~ 15cm pots are commonly used for Bleeding Heart Vine. Each pot can be planted with 3 plants.Generally every 1 ~ 2 years for a replacement, replacement time in early spring or after the flower. When replacing the pot, first use broken tiles to pad the drainage hole, and then put a small amount of bone powder as base fertilizer, and then load the new culture soil, plant the plant, leaving 2 ~ 3 cm along the mouth, so as to fertilize and water. Change the pot after pouring permeable, put the shade of slow seedlings, slow seedlings moved to the sunny place after maintenance.
In the beginning, it is just a few brown spots, but if not treated in time, it will give rise to large black spots and yellow leaves will die. So once found sick, we should immediately use chlorothalonil 800 times liquid, foliar spray, once every 7 ~ 8 days, 2 ~ 3 consecutive times, and it can be basically cured.
The main pests are scale insects, whitefly, etc., and can be sprayed with 40% oxidized dimethoate solution 1000 to 1500 times. Leaves can not stretch normally caused by alkaline soil, leaves lose green and yellow, and can be irrigated with 0.2% ferrous sulfate solution. For Mosaic disease and mycosis, it is necessary to remove the diseased leaves in time, strengthen ventilation, and keep the leaves dry, which can control the disease.
