How to raise Iron Begonia what is the reason why the leaves of Iron Begonia turn yellow

Iron Begonia is a plant with beautiful flowers and eye-catching colors, which can be placed at home to beautify the room and purify the air. Let's take a look at how it can grow healthily.

The Culture method of Iron Begonia

1. Soil: potted plants are required to use sandy loam, which can be made of rotten leaf soil or peat soil plus sandy soil and a small amount of fertilizer.

2. Watering: iron begonia is resistant to drought, and watering in spring and autumn should be dry and wet. Can be watered once a day in summer, waterproof in rainy season, not dry and watered in winter, the basin should not be moist for a long time; the flowering period should also be controlled, the water is easy to cause falling flowers and rotting roots.

3. Sunshine: iron begonia likes plenty of sunshine and should be given more light all the year round. During flowering, if there is plenty of sunshine, the bracts will be colorful and the flowering period will be long; if the sun is insufficient, the flowers will be dim, and if they are cultured in shade for a long time, they will not blossom or rarely bloom. Iron begonia likes warmth and is not resistant to cold. The northern area generally leaves the room in early May, puts it in the sunny place, and enters the room in early October, where there is sunshine in the room.

4. Temperature: iron crabapple likes warmth and is not resistant to cold. It grows best at about 22 ℃ in daytime and 15 ℃ at night. It keeps 15 ℃ to 20 ℃ in greenhouse and blossoms all the year round. If it falls to 10 ℃, the deciduous leaves turn to semi-dormancy.

5. Fertilization: prickly plum does not like thick fertilizer. When planting, you can choose some cultivated soil to pad the hoof horn as the base fertilizer. In its growing period, usually apply mature thin cake fertilizer and water once in 3-4 weeks, fertilizing too much, especially too much nitrogen fertilizer, branches grow too long, only long leaves do not blossom. In general, the Beginning of Autumn can stop fertilizing, while iron begonia can not use fertilizer with oil. If the phosphorus and potassium fertilizer is applied 1-2 times during the bud period, the flowers will be more and the color will be bright.

6. Insect pests: stem blight and rot mainly occur. 50% carbendan 800 times solution is sprayed once every semimonthly. Insect pests are harmful to whiteflies and scale insects, which are sprayed with 1500 times of 50% fenitrothion EC.

7. Pruning: the flowers of iron begonia blossom at the top of the new branch. if you want them to blossom more, they must be pruned properly. Because the main branch is too long, it blossoms less. Therefore, the overlong and irregular branches should be cut short after flowering. Generally, two new branches grow under the cut mouth of the branches, and when the new branches grow to 5 to 6 meters, they can blossom. Prune once a year, and after a few years, the whole plant will be full of bright little red flowers. As the branches are slender and soft, as the plant grows, bamboo sticks or wire can be used to tie the branches into different shapes to tie them into a style, which can show the beauty of safflower and green leaves when flowering. If it is not pruned in time and let it grow naturally, the main branch will grow longer and longer, not only blossom less, but also the plant shape is not beautiful.
