When does zinnia bloom (brief introduction of zinnia flowering period)

The so-called Centennial Red, also known as Wei Zihua, didn't know that Wei Zi was a flower and a long-lived tree species until I watched TV dramas as a child. It has a very long history in China, and has gone international with its beautiful flowers. Its trunk is smooth and clean, and its flowers are more beautiful. It usually blooms in early summer and lasts for half a year. It's called "Hundred Days Red".

In winter, it is a "little bachelor", and all the leaves on the branches are lost, and it is not until spring that the young leaves are restored. One month is enough time for the leaves to grow. For flowering arbor plants, the focus of daily management should be sunshine. Spring sunshine and air humidity can make new leaves mature and grow. The sunshine in summer is really strong, but Osmunda japonica can still resist, but if conditions permit, it can properly block the sunshine and have a certain protective effect on the formation of flower buds.

Pruning and shaping in spring is also the most important. It is best to deal with some old branches in early spring before the plants fully wake up. Most of its flowers are in full bloom on the new branches born that year, so it is necessary to dispose of the nutrients on the old branches before returning to the growth of the new branches. For example, don't keep these branches densely packed and crossed, and try to ensure that they don't consume nutrients.

If it grows normally in spring, many new branches will grow in half a month, and adventitious buds will appear at the roots, which should be removed. At the same time, observe the growth intensity of branches. Some branches can grow quickly, so just cut them short and keep them more than ten centimeters long. One is to prevent them from growing in vain, and the other is to balance the absorption of nutrients by each branch.

Generally speaking, pruning is divided into two levels, one is pruning on the main branch, and the other is layered treatment. The former is mainly aimed at those big branches. It is enough to leave three to five branches on the plant, and the rest can be pruned in large quantities, and the selected ones should also be treated. Proper truncation will greatly promote future growth and modeling. It can also be trimmed into an umbrella-shaped crown shape, which will look more atmospheric when it blooms.

The second is to prune the crown that has been formed, observe the lateral branches of plants with different growth heights, and prune them appropriately according to their growth trends. Shorten the strong ones slightly and remove the bad ones completely. It is enough to leave three to five leaf buds on each selected branch. That's not all. There are secondary side branches, but the method is the same, and the retention of leaf buds is the same. Through this pruning, the shape of plants will develop into a cloud-like shape, which will make the growth of plants more multifaceted.

The pruning of plants is mainly to maintain the appearance, and secondly it can play a certain role in promoting. For different growth stages of Osmunda japonica, the methods adopted are somewhat different, but the purpose is the same, and the specific operation is not difficult. What is more testing is your observation and treatment of plant morphology.

Before flowering in early summer, we should seize the growing period of spring, get more sunshine, and don't leave any branches that should be cut off. Do these two things, and you can do it. Xiaohua believes that after this May, Ziwei will be different.
