How to grow sunflowers with water so that they don't rot? What to do if the sunflowers don't adapt to the pot

Sunflowers are also called sun-invulnerable plants. They are easy to grow and can grow well without too much intervention. They are common in many families. Sunflowers are usually planted in the soil, but they can easily grow well and have extra branches. In this case, you can use hydroponics.

How to keep sunflowers from rotting when growing them with water

1. During hydroponics in summer and autumn, the branches are slightly longer, about 20 cm, and then the leaves at the bottom are removed to prevent rot. Then the cuttings are planted in water. Do not soak them in water too much. Change the water frequently before roots grow, and change the water less frequently after roots grow.

2. When hydroponically growing sunflowers, do not place them under the sun. They are different from those in potting soil. Just place them in a place with diffused light and good ventilation. Generally, as long as the temperature is suitable, white roots will begin to grow in more than a week. Hydroponics is very simple and they can also bloom. In addition, in autumn and winter, if you are worried that sunflowers cannot withstand frost, you can cut some branches and hydroponically grow them. Put them at home and continue to grow them.

3. After the hydroponic sunflowers have grown roots, they can also be planted in pots. However, due to limited nutrients, hydroponic sunflowers will definitely not grow faster or bloom more than the sunflowers grown in soil.

What to do if the sunflower does not adapt to the pot

Water thoroughly

The growth of sunflowers cannot be separated from water. In summer, the temperature is high and the water evaporates a lot. If the pot soil is dry, it needs to be watered. If it is not watered in time, the capillary roots that have just grown will dry up, and then it will dry up, and the branches will also dry up, not to mention growth.

Avoid strong sunlight

Newly planted sunflower seedlings should avoid strong sunlight. If the sun is too strong and the temperature is too high, the seedlings will become stiff. Even if they can barely bloom for a long time, they will bloom small and cannot bloom into flower balls like others. Before the sunflowers show vigorous growth momentum, they should be placed in scattered light, or exposed to the sun in the morning and afternoon when the sunlight is weak, avoiding strong light at noon. Scattered light maintenance helps the root system grow, more developed capillary roots, and luxuriant growth. If the branches do not grow, the roots will not grow well.

More ventilation

On the one hand, avoid direct sunlight at noon, on the other hand, ventilate more, and sprinkle water on the leaves and around in the morning and afternoon. Ventilation is one of the important strategies to promote growth, and it is best to have 24-hour ventilation conditions.

Fertilization

Place the newly planted sunflowers in a cool and ventilated place, keep the soil moist, and they will grow vigorously in four or five days. When you see that the stems of the sunflowers have begun to grow and the leaves have become vigorous, apply a small amount of fertilizer appropriately, and they will grow quickly. The fertilizer must be thin, and only five or six grains of inorganic compound fertilizer are needed, and it can be applied once every half a month.

How to care for hydroponic sunflowers

Shade the roots of sunflowers. We all know that sunflowers are the most sunlight-loving flowers, hence the name. However, since the roots of hydroponic sunflowers are in the water, they cannot be directly exposed to the sun. So what should we do? This requires sunshade for the sunflower basins, otherwise the water temperature will be too high and the roots of the sunflowers will be killed. Sunflowers need sunlight to bloom more.

Fertilization. When hydroponically growing sunflowers, you need to add a few drops of nutrient solution to the water every 7 days or so to ensure that the sunflowers grow normally and bloom. When there are flower buds, you need to apply some aqueous solution of phosphorus and potassium fertilizers to the sunflowers every 15 to 20 days, so that the flowers will be more numerous and brighter.

Change the water. Hydroponic sunflowers need to change the water regularly because the nutrient solution in the water can easily breed mosquitoes and bacteria. Change the water for sunflowers every other week in spring and autumn, and twice a week in hot summer. Generally, changing the water is done at the same time as fertilizing.
