If you want to raise a potted flower that is easy to take care of, has many flowers and long flowering periods, then Blue Demon recommends you to raise petunias. Petunia is a flower that is very easy to bloom and has a variety of colors, which is very suitable for potted plants. So how can we maintain petunia to bloom? Today, Blue Demon will share with you the method of petunia . I hope it will be helpful to you.
Methods for popping petunia
Petunia is a flower that can be planted all seasons, but if you want to easily achieve the pillow effect of petunia, then Blue Demon recommends that you choose to sow seedlings in autumn, or buy seedlings in autumn to cultivate them. Because in autumn and winter, the temperature gradually decreases, the growth rate of petunia will slow down, which is more conducive to nutrient accumulation. Because of the slow growth, the joints of petunia branches are relatively short, and the entire plant will grow more compactly.
Therefore, it is very important to choose the appropriate time for seedling cultivation. If the seedlings are raised in spring, the petunia will grow faster, the branches will grow longer, and the entire plant will appear looser.
Of course, it is unrealistic to rely solely on adjusting the seedling cultivation time to achieve the effect of bursting the pot. If we want petunia to open the burst pot, we need to meet the following three conditions.
1. Keep enough light
Petunia is a sun-loving flower. If you want petunia to grow strong and have many branches, you must keep enough light. Just keep full sunshine as much as possible in autumn, winter and spring. If the light is insufficient, the branches of petunia will grow weaker, and the internodes will become, and the compactness of the natural plant will become worse and the later flowering will become less.
2. Keep enough fertilizer
If petunia bloom a large pot in spring, then fertilization is essential. From the growth of 5-6 real leaves in petunia seedlings, you should insist on top dressing. Throughout the autumn and winter seasons, Blue Yao recommends that you apply compound fertilizer water or fermented bean cake fertilizer water every 10 days. Huaduoduo No. 1 is fine.
The watering interval in autumn and winter is long, so you can bring some fertilizer every time you water. If the temperature is above 5 degrees in autumn and winter, the petunia is in a slow growth stage, so you should continue to top dressing. If the temperature is too low, it is recommended to put it in an indoor balcony for maintenance, which can grow faster and the crown will be larger when it blooms in spring.
3. Appropriate topping and stimulating branches
Generally speaking, if you want the petunia plant to have a compact and full shape and bloom, it is necessary to stimulate branches. However, the methods of topping petunia of different categories are completely different. Here, the blue monster uses common petunia standing and hanging petunia as an example.
The branches of upright petunia grow upright. If this type of petunia species does not top during the growth period, they often have fewer branches and higher plant heights, and may easily fall when they bloom.
So, when the seedlings grow to about 5cm tall, the branches should be topped and promoted when they do not see the side branches. If many branches have already grown, you can do not top it at this time. First observe the growth, because some petunia varieties have very good natural branching properties. If they do not top it in autumn and winter, many branches can naturally grow without top it.
Upright petunia will generally top 2-4 times in autumn and winter. Depending on the growth of the seedlings, the first time is to top the main branch, and the second time is to top the growing side branches. Generally, the side branches can be topped again when they grow to 3-5cm tall, and stop topping after the plant is full. Sometimes the plant shape is not full enough and there are already buds. At this time, you can pinch off the buds together.
The hanging petunia has different growth directions and different tops. Generally, the hanging petunia branches are grown close to the basin surface and are in a creeping state. It usually takes a wait to top the hanging petunia. The side branches grow to the edge of the pot before topping. Of course, it is also OK to top it earlier. It depends on your requirements for plant shape.
When topping, remove the top buds of the side branches and let the side branches grow new side branches. However, be careful not to pinch the top buds of the main branch in the middle, otherwise it will become the Mediterranean when the petunia blooms.The hanging petunia can also top the side branches many times. When the crown is full, it can stop topping, and it will naturally explode in spring.
