How to grow a Knockout Flower into an old trunk
In detail for netizens on how to grow a Knockout Flower into an old trunk and the cultivation techniques of Knockout Flower, let's take a look together.
Usually, the Knockout Flowers we buy are in a pot with multiple plants, short in height, and with flowers at the top. However, after this kind of Knockout Flower blooms, pruning the flowers makes them look unattractive, and many people want to grow a single seedling into an old trunk, as a cluster bloom is the most beautiful. So how should we cultivate the "old trunk" of Knockout Flower? Today, Xiaoqi will tell you about the cultivation methods. Only by strictly following four steps can the flowers bloom beautifully and turn into a small flowering tree.
1, Pruning
If you want the old trunk of Knockout Flower to become thicker and older, pruning is essential because pruning can control the plant's top to branch out more, resulting in more flowers. During the pruning process, the bottom leaves will fall off, and the main stem will gradually become thicker. So, we separate the multiple seedlings we buy and plant them individually in a flower pot. Use well-draining soil and avoid using too large a pot. After the roots have grown well, ensure proper pruning. Generally, only one main stem at the bottom is retained, with a height of more than five centimeters, then allow it to grow new branches and cut off the top.
After cutting off the top, multiple branches will grow from the top. Do not rush to prune these branches; let them grow first. When they have grown about six leaves, pinch off the two small top leaves. After pinching, each branch will grow two to four buds. When these buds grow taller, retain two to four leaves at the top and pinch off the rest. Continue this process until the top has many side branches and the canopy is full. When you stop pruning, you will find that the bottom main stem becomes very thick and gradually ages, which is the old trunk of Knockout Flower.
2, Sunlight
During the process of pruning and topping, it is crucial to ensure adequate sunlight. If there is insufficient light, the new buds will be thin and weak, with a large spacing between the leaves, and this will be the case even if new buds grow. The entire plant may later become droopy, bending, or breaking. Therefore, during the entire pruning process, sunlight must be sufficient. Sufficient sunlight allows the main stem to grow thicker, the leaves to become more robust, and the internode spacing to be shorter.

3, Fertilizing
If you want Knockout Flower to grow quickly, fertilizer is indispensable. If you do not fertilize, even after pruning, the side buds will not grow much, possibly only one, or may not grow at all after pruning. So, during the entire process, fertilizer cannot be stopped, and the right fertilizer must be chosen. It is generally recommended to use a balanced nitrogen, phosphorus, and potassium fertilizer, which provides balanced nutrients and promotes root development, allowing for normal growth. Common general-purpose nutrient solutions and compound fertilizers are all suitable, applied two to three times a month, with a moderate concentration to ensure nutrient supply for rapid growth.
4, Proper watering
Knockout Flower has thick leaves and a robust main stem, making it relatively drought-tolerant. However, water is essential during the entire growth process. If it lacks water, it will damage the roots, and since it has many fine roots, new roots will grow, stopping growth during this process. Moreover, after the roots dry out, watering again can easily cause rot, possibly leading to complete decay from the bottom. The correct watering method is to water thoroughly when the potting soil is half-dry, under the conditions of good soil drainage and ventilation. If ventilation is not good, wait until the soil is completely dry before watering.
Knockout Flower is very easy to care for and is also very affordable, with many colors and varieties. If you want to grow an old trunk, follow Xiaoqi's instructions and strictly follow these four steps, prune regularly to grow it into an old trunk, ensure adequate sunlight, and fertilize and water it regularly, which will promote rapid growth. Generally, seedlings bought in spring can be grown into an old trunk by winter, and the flowers will be absolutely beautiful. Many people have tried it, and you can try it too.
