If you are in the south, you should also move the potted plants to a sunny place after beginning of winter, which is not only convenient for the potted plants to bask in the sun, but also convenient for avoiding the cold. The indoor temperature should be kept at 15℃ to 20℃ during the day and not lower than 10℃ at night. In the low temperature environment, the plant growth is weak, which is not conducive to flower bud differentiation, little or no flowers, but the environment above 25℃ is also not conducive to its growth and flowering. Geranium likes drought and is afraid of wet, so it should be watered properly every day, especially in winter. Even in dry weather, water is usually poured every five to seven days to keep the soil dry and slightly wet.
Too much watering will cause leaves to turn yellow and fall off, affect flowering, and even cause root rot and death. However, the leaves are often sprayed with clean water to keep them clean, which is beneficial to photosynthesis. In order to make geranium bloom continuously, it is necessary to supply sufficient nutrients. Generally, dilute liquid fertilizer is applied once every 65,438+00 days, which can be mixed with bean cake, hoof slices and fishy water, and then added with water after fermentation. You can also use the compound fertilizer sold by the flower shop, as long as 3 to 5 tablets at a time.
Geranium has many branches. In order to promote it to blossom more, it is necessary to pick the heart of the plant many times to promote it to have more branches and more pregnant buds. After the flowers wither, cut off the residual flowers in time and cut off the branches that are too dense or too thin to avoid consuming nutrients. But in the dead of winter, it is not suitable to cut again.
Geranium is a widely planted flower in the family, which has both flowers and leaves, and is also a good material for arranging flower beds and flower diameters. Because it grows fast, it needs pruning and plastic surgery every year. Generally speaking, plants are pruned at least three times a year. The first time was in March, mainly thinning branches; The second time in May, cut off withered flowers and too dense branches; The third pruning after beginning of autumn was mainly plastic surgery.
How to prune and shape plants?
Generally, after the dog days, the weather turns cold, geraniums gradually resume growth, and dormant plants have sprouted. At this time, it is from late August to early September, that is, the plants are pruned comprehensively by changing pots. According to the growth situation of the plant, generally choose 3-5 main branches that grow well and are evenly distributed near the base, and cut other branches that are too dense and delicate from the base. Then, the main branches and side branches are cut short, and only healthy fairy buds are left in each side branch, so that the branches of the whole plant are evenly distributed and compact, and the plant shape is plump and short.
For plants cultivated for one year, they can be cut short at appropriate positions. It will take some time for the pruned plants to grow again. Generally, after half a month of drying, normal fertilization can be started, so that new buds can sprout and bloom one after another. In order to avoid excessive false growth, we can collect the core to promote multi-lateral branches to bloom more.
