When and how to change the soil of sunflowers

Sunflower soil changing time

It is best to change the soil for sunflowers in spring and autumn. The temperature and humidity are suitable at this time, and the plants begin to resume growth. If the soil is changed, the survival rate will be higher and the growth will be better.

How to repot and change the soil of sunflower

1. When changing the soil of sunflowers, it is generally recommended to do so with the soil. At the same time, it is necessary to cut off the yellowed, wilted and other bad leaves on the lower part of the plant. This will make it easier for it to adapt to the pot and avoid unnecessary nutrient waste.

2. Next, build a drainage layer at the bottom of the larger new pot, and then fill the bottom of the pot with a layer of fertile and soft nutrient soil, about 3-5 cm thick. Then place the sunflower potted plant and the soil in the center of the pot, and fill the soil until the gaps inside are filled.

3. But do not fill the soil too full. Generally, it is enough to occupy 70% to 80% of the space in the flowerpot. Then compact the soil on the surface of the pot with your hands and water it thoroughly as rooting water until water flows out of the outlet at the bottom of the pot. It is best to put a tray filled with water at the bottom of the flowerpot, pour out the excess water in the tray, and then put the flowerpot into the tray.

Sunflower soil replacement precautions

1. After changing the soil of the sunflower, you can water it thoroughly once to keep the substrate moist. Then control the watering and wait until the soil is completely dry before watering again. The sun should not be seen at this time. It needs to be maintained in a semi-shaded environment. After the plant has adapted to the pot, it can be watered and fertilized normally.

2. Sunflowers like fertile soil with good air permeability. The substrate can be prepared by mixing peat, vermiculite and sand in a ratio of 2:1:1. A small amount of organic fertilizer can be added to improve the soil fertility and promote the plant's acclimatization.

Maintenance method of sunflower after soil change

Sunflowers cannot be exposed to the sun immediately after the soil is changed. There is a period of seedling acclimatization at this time. It is necessary to wait until it adapts to the pot before providing sufficient light. It is also necessary to water it in time to keep the substrate moist. No water accumulation should occur. In addition, a thin liquid fertilizer needs to be applied once every half a month during the growth period.

Watering after soil replacement

After changing the soil of the sunflower, you can water it thoroughly once, and then you need to wait until the soil is completely dry before watering again. The sunlight at noon in summer is relatively strong, so you cannot water it at this time. You can only water it in the morning or evening.

See the sun after changing the soil

After changing the soil of the sunflower, it is best to place it on a balcony with scattered light and ventilation conditions for maintenance. Wait until the roots take root in the new soil and the stems and leaves of the plant regain growth vitality, especially after its leaves unfold, we can let it bask in the sun.

Leaves turn yellow after changing soil

The yellowing of sunflower leaves after changing the soil may be caused by improper watering, improper fertilization, too strong light, and poor ventilation. Remedial measures need to be taken according to the actual situation. It may also be that the plant has not yet adapted to the new environment, which can be alleviated by careful care for a period of time.
