Petunia, officially known as bidong eggplant. Solanaceae is a perennial herb, often cultivated for one or two years. I believe many flower friends have planted or have planted petunias in their families, but some flower friends are not very attentive to the pruning of petunias and let them grow. Xiaobian wants to tell these flower friends that this kind of management method is harmful to petunias but not beneficial. Why do you say that? Look down and you'll see.

Why to prune Petunia? Why to prune Petunia regularly? Because Petunia grows very fast, fast growth means that it decays fast, and the only way to keep it blooming is strong cutting, so the pruning of Petunia is also very important.
Petunia's vigorous growth period is in June, July, August and September. I will forcefully cut it once in about three weeks, and it will be full of flowers about 10 days after the forceful cutting. Some friends often exclaim when they see my forceful cutting of Petunia: "what a pity, there are still many flowers to be cut!"
In fact, after planting for a long time, you will find that the growth cycle of dwarf cattle is the same as that of many plants.
The first is the introduction period, during which the seedlings bought (or sown by themselves) begin to breed a large number of flower buds after artificial planting, pinching and shaping;
Then there is the growing period, during which the flowers begin to bloom, and many buds gush out and continue to open;
The next stage is the mature stage, during which the whole pot of flowers is in full bloom and each bud is in full bloom;
Finally, there is the decline period. In this period, more flowers fail than the buds grow. The longer the plants grow, the more scattered they become. Although they seem to be prosperous on the surface, they are actually dead in name. In this period, we should not hesitate to cut the dwarf cow. The harder we cut it, the better the flowers will bloom. If we wait until this period is over, the flowers fail completely, and the plants wither, we can cut the dwarf cow Most of them will die.
I usually buy seedlings around May Day and plant them in pots for about three weeks. Next, before the cold wave strikes on October 20, I will cut them 3-4 times, mainly in July, August and September. Dwarf cattle can be used as a biennial herb if they are cut and managed well.
Why to prune Petunia? How to maintain Petunia? 1. Potted flowers placed in sunny place, grow luxuriantly, bloom more and bloom longer.
2. Pruning and pruning should be carried out at any time, and the residual flowers or branches should be cut off in time, which can not only prevent excessive growth, but also promote more lateral branches, more pregnant buds and more flowering.
3. In the whole flowering period, the thin fertilizer with nitrogen and phosphorus should be applied 1-2 times. When fertilizing, we should pay attention to not too much nitrogen fertilizer, otherwise it is easy to cause plant lodging and affect the ornamental and flowering. Usually should pay attention to watering to prevent dry, but avoid water, in order to prevent rotten roots.
