As a common indoor foliage plant, Sunflower is loved by people for its elegant form and unique leaf texture. However, as it grows, repotting becomes an inevitable task. Repotting can not only provide more space for the sunflower to grow, but also renew the soil and inject new vitality. However, repotting is also a technical job, and there are some key details that need to be paid attention to. Next, let's take a look at the key points and precautions for repotting of sunflowers.
1. Choose the right pot
Choosing a new pot that is suitable for sunflower is crucial. The size of the new pot should be determined according to the root system of the sunflower, both to ensure that the root system has enough space to grow, but not too large to make the soil too wet. In terms of material, ceramic or plastic basins with good air permeability are good choices.
2. Prepare new soil
At the same time as repotting, it is also necessary to prepare new soil for the sunflower. Choosing well-drained, organic-rich soils can provide a better environment for them to grow. Consider adding some humus or perlite to enhance the permeability of the soil.
3. Keep the root system intact
When removing sunflower from old pots, special care should be taken to avoid damaging its root system. You can gently pat the sides of the old pot with your hands to help the soil separate from the wall of the pot, and then gently remove the plants.
Fourth, prune properly
After removing the sunflower from the old pot, its root system can be pruned appropriately. Removing old, diseased roots can promote the growth of new roots. After pruning, the roots can be soaked in carbendazim solution for disinfection.
5. Correct planting
Spread a layer of drainage at the bottom of the new pot, then place the sunflower in the new pot and fill the pot with new soil. Make sure that the root system of the sunflower spreads out and is tightly bound to the soil. Gently compact the soil to avoid leaving voids.
6. Maintenance after repotting
Repotting sunflower requires special care. First, place it in a cool, ventilated place away from direct sunlight. Second, keep the soil moist but avoid overwatering that can lead to water accumulation. Foliar water can be sprayed appropriately to help plants rejuvenate.
7. Precautions
Avoid repotting during the peak growth or flowering period of the plant, which may adversely affect its growth.
Make sure the soil is dry before repotting, which makes it easier to get the plant out of the old pot.
New pots are cleaned and disinfectedto avoid the invasion of germs and pests.
Can you fertilize after repotting?The answer is yes, but choose the right fertilizer and concentration to avoid burning the plant. It is recommended to supplement with organic fertilizers.
Pay attention to the state of the plant after repottingOnce an abnormal situation is found, it should be dealt with in a timely manner.
Although the repotting of sunflower may seem simple, it actually involves many details and techniques. Only by mastering these points and precautions can we ensure the success of repotting and allow the sunflower to continue to grow healthily and vigorously in the new environment. Through the above introduction, I hope to provide you with some useful reference and help in actual operation.
