Growth habit of begonia americana

American Begonia has strong stress resistance, extremely thin tolerance, strong cold tolerance, sun-loving, drought-tolerant, hydrophobic, grows well in arid areas and is easy to manage. After late autumn, the temperature gradually dropped, and the growth of begonia pendula was also inhibited. After entering the semi-dormancy state, new branches and leaves do not grow, and flowers are scarce. The temperature in northern China is low in January and February, and sometimes it is frozen continuously. American begonia families may freeze to death if they don't pay attention to keep warm. Therefore, potted plants should be moved to a sunny place indoors before frost.

Air humidity and soil pH regulate the concentration and brightness of autumn leaves, and the leaves are more vivid when there is enough rainfall. Use colorful begonia in the yard, give enough irrigation in summer to fatten the leaves, and don't dry it in autumn.

May is the most attractive time for fresh leaves of begonia in America. The colors of the first leaves are getting brighter and brighter, and the new leaf tips are brighter and more beautiful than the first leaves in April. The colorful leaves penetrated by sunlight are as bright and soft as flowers, and the viewing period of new leaves appears constantly during the growth period of plants. For example, Happy Sunshine is frosty red, Liszt is wine-like red, and Beibei from the Thunderbolt is purple. This makes the company of green Chun Xue, dark green Adam and dark green red Barron even more charming. From mid-May to mid-June, the leaves of Malus americana showed outstanding performance.

From July to August, due to the high temperature, most begonias no longer sprout, and their colors gradually stabilize, which can be divided into green leaf group, red leaf group and red and green leaf group, with different color differences in each group. For example, among the varieties of red leaves, "Thunderbird" is brighter than "Royal Family"; Among the green varieties, "Donna" is stronger than "Chun Xue"; "Pink Roof" is dark green and reddish brown, while "Liszt" is olive green and bright red. The degree of red is also very different. Midsummer is the darkest season of begonia leaves, and the bright red color of the "royal family" in spring becomes dull at this time, giving people a dark feeling.

The mature leaves of some begonia trees will appear autumn colors in autumn, such as the leaves of "Indian magic" are orange; Donna will have green, orange and lemon yellow trees; "Feng" autumn leaves turn purple to orange and so on. Begonia is located as a northern tree species, and the area suitable for begonia growth has four distinct seasons. When the temperature difference between day and night is large in autumn, the color of many begonia leaves changes obviously. Although there will be no bright red of red maple, it is bright orange or golden yellow.

The fruit of Begonia americana can expand rapidly after flowering, and the time of hiding behind the leaves is only 2 to 4 weeks. Many varieties have different degrees of red when they are young. With the constant change of seasons, the longer they are, the brighter they will be. July to August is the best season to see Xia Guo. At this time, the leaves are dignified and steady, setting off the red and transparent branches and the ripe fruits of Huang Chengcheng. The edible big fruit "Doug" is gorgeous and amazing, with a fragrant smell; The fresh and tender color of "beaming" in spring has also changed into emerald green, setting off a string of beautiful fruits full of lantern-shaped magenta, which looks like safflower from a distance; The fruit of "Redjade" is flushed after the plain apple green in June and the white green in July, and it is red in late summer, like a string of rubies hanging on the elegant and soft branches. "Shengfeng", "Indian Magic" and "Snowdrop" are very different in color, and the amount of fruit hanging is incredible.

The storage period of begonia fruit varies greatly among different varieties, even as long as several months. In the mature season, apples will naturally mature and fall off. Longevity fruits are mostly small fruits, which are generally edible large fruit varieties. Fruits fall into two categories. First, the pulp and fruit in autumn and winter will not fall naturally, but most of them will become delicious for birds. The other kind is hard fruit without pulp, which can stay on the tree until it is completely dry in winter, such as Donna, Red Barron, Adam and Ruby. When it blooms again the next year, the begonia still hangs firmly on the tree.

The ornamental period of the persistent fruit can last until March to April of the following year in a humid environment. In the environment of dry air in winter, although the fruit hangs on the tree, the dry wind in early February and spring will make its peel dry and wrinkle, just like dried red dates, which greatly reduces the landscape effect. The best fruit viewing period of American Begonia is generally from July to 65438+ 10 in the following year, and the fruits with ice and snow are the most vivid.
