Sunflower is a common houseplant with beautiful leaves and flowers, as well as purifying the air. However, sunflower also needs to be repotted regularly to maintain healthy growth. This article will introduce the timing, methods and precautions for repotting of sunflower to help you provide the best growing environment for sunflower.
There are generally two situations when to repot a sunflower:
One is that the root system of the sunflower has occupied the potting soil, and even protrudes from the bottom of the pot, at this time it is necessary to change to a larger pot so that the root system has enough space to grow.
The second is that the potting soil of the sunflower has aged and lost its air permeability and nutrients, so it is necessary to change some fresh potting soil at this time so that the root system can absorb water and nutrients.
Generally speaking, the repotting cycle of sunflower is 1-2 years, depending on the growth of sunflower and the condition of the potting soil. The best season for repotting is spring or autumn to avoid damage from high or low temperatures.
The repotting method of the sunflower is as follows:
First of all, prepare a suitable new pot, which is generally one size larger than the old pot, and the bottom of the pot should have drainage holes. The new pot should be rinsed with clean water, disinfected, and then spread a layer of ceramsite or broken bricks at the bottom of the pot to increase drainage.
Secondly, remove the sunflower from the old pot and gently pat off the old soil from the roots with your hands, taking care not to damage the root system. If the root system is too dense, some old roots can be pruned with scissors to promote the growth of new roots.
Again, put the sunflower into a new pot, adjust the position, and then fill the pot with fresh potting soil, the potting soil should be loose and not too tight. The composition of potting soil can be a mixture of humus, garden soil and sandy soil in a ratio of 3:2:1, and some organic fertilizers can also be added to increase nutrients.
Finally, pour the potting soil thoroughly with clean water to allow the water to flow out of the bottom of the pot to remove excess air and moisture. Then place the sunflower in a ventilated, shady place, away from direct sunlight, to allow the sunflower to adapt to the new environment.
Pay attention to the following points after repotting:
Do not apply fertilizer immediately to avoid irritating the root system and causing root burning. Generally, it is necessary to wait for the normal growth of the sunflower to resume normal growth, and then apply fertilizer appropriately, once a month.
Do not overwater as it may cause root rot. Generally, it is advisable to wait for the surface of the potting soil to dry before watering, about once a week.
Do not move the position so as not to affect the adaptability of the sunflower. Generally, it is necessary to wait for the stable growth of sunflower, and then adjust the position appropriately according to the changes in light and temperature.
Sunflower is a beautiful and practical plant, and repotting is an important step in maintaining its healthy growth. As long as you master the timing, method and precautions for repotting, you can provide the best growth environment for the sunflower, let it bloom more flowers, and add a touch of green to your life.
