First, trim
If asparagus grows wildly. The simplest and most effective method is pruning. If you grow too tall and too fast. Its branches will be pulled up. It is also possible that the upper branches have no leaves and are not beautiful.
You can cut it short properly at this time. Cut off the branches at the height you think is appropriate. Retain nutrients and promote the growth of lateral buds from the bottom. Control the height to make its lower part grow more lush and oily green.
Second, apply less chemical fertilizer.
If the temperature, humidity and light are suitable, asparagus grows very fast. If you want a small shape. Reduce fertilization, control watering a little, and often spray water on plants. Let it not have enough fertility and water to grow high.
Third, pruning the root system.
Asparagus has a well-developed root system. If its roots are stretched indefinitely to absorb nutrients. Asparagus grows very fast. When maintaining asparagus or changing pots of asparagus, you can trim its long roots. Change to a slightly smaller flowerpot. In this way, its roots have nowhere to stretch, the nutrients it absorbs are limited, and its natural growth will be very slow.
Fourth, spray chlormequat chloride.
If you think asparagus grows too fast. When the plant is more than ten centimeters, it can be sprayed once every half month. Spray it three times at a time. Can effectively control the growth of leaves and branches. Play a role in dwarfing asparagus.
Of course, if you don't want asparagus to grow too tall and keep it small all the time, you can choose short asparagus when choosing asparagus varieties. Then put it in a beautiful flowerpot to make a bonsai. So you don't have to worry about asparagus growing too fast and too high.
