What fertilizer should be applied to sunflowers? What should I do if the sunflowers with multiple flowers keep refusing to adapt to the pot?

Sunflowers are a very common flower, and they bloom as long as they see the sun, so they are called sunflowers. Sunflowers are brightly colored, red and yellow, and it is very beautiful if there are several flowers in a pot. So what kind of fertilizer can make sunflowers bloom more?

What fertilizer should be applied to sunflowers to make them bloom more

When planting sunflowers, you should choose soil with good air permeability, because sunflowers are most afraid of water accumulation. Once water accumulates, the roots will rot. Then mix the soil with good air permeability with well-rotted chicken manure and sheep manure, put a layer of soil with good air permeability on top, sow the seeds, and finally sprinkle one centimeter of soil on top, and then water it thoroughly.

Then, apply a diluted solution of potassium dihydrogen phosphate when the sunflowers are growing buds. Because if potassium dihydrogen phosphate is sprayed when the sunflowers are blooming, it is easy to cause the sunflowers to rot. Applying a diluted solution of potassium dihydrogen phosphate can avoid this problem. And the final effect is the same.

What should I do if the sunflowers I planted don’t adapt to the pot?

1. Water thoroughly

Sunflowers cannot grow without water. In summer, the temperature is high and the amount of water evaporates greatly. Watering is necessary when the soil in the pot is dry. If watering is not timely, the newly grown capillary roots will dry out again. If this happens repeatedly, the branches will become yellow and dry, not to mention growth. The flower pot you have seems to be relatively shallow. If the soil in the pot is breathable, water it thoroughly when it is dry.

2. Avoid strong sunlight exposure

Although sunflowers are also known as sun-invulnerable, newly planted seedlings should be protected from strong sunlight. If the sun is too strong and the temperature is too high, the seedlings will become stunted and will not grow for a long time. Even if they can barely bloom, they will bloom in small and few flowers, and will not bloom into flower balls like others. Before the sunflowers show vigorous growth, they should be kept in diffuse light, or exposed to the sun in the morning and afternoon when the sunlight is weak, avoiding strong sunlight at noon. Maintenance in diffuse light is conducive to root growth. The more developed the capillary roots, the more luxuriant the branches and trunks will grow. If the branches and trunks are sick and do not grow, the roots will not grow well. The sunflowers in your pot are currently a bit stunted, and the seedlings and roots are not growing. Don't expose them to the sun too strongly, nourish the roots and seedlings, and then gradually expose them to the sun when the roots and seedlings begin to grow.

3. Provide more ventilation

In summer, the temperature is high, and most potted flowers do not grow well due to the heat, and the sunflowers with underdeveloped root systems are also like this. So we need to find ways to cool down, on the one hand, avoid strong sunlight exposure at noon, and on the other hand, ventilate more, and sprinkle some water on the leaves and around in the morning and afternoon. Good ventilation is the most important strategy to promote growth, and if conditions permit, ventilate 24 hours a day.

4. Fertilization

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

How to propagate perennial sunflowers by cuttings

First, the sunflower cuttings taken from the mother plant must be dried in the sun for about a day or two. After the wounds heal, the cuttings will be more likely to survive. This is the opposite of the cuttings of other flowers.

Second, the substrate for cuttings can be fine river sand or garden soil without fertilizer. Everyone must remember that there must not be any fertilizer in the soil, as the cuttings will rot easily if there is fertilizer.

Third, the main reason why sunflower cuttings cannot survive is that the soil is too wet. In order to prevent the soil from being too wet for a long time, we can water the soil thoroughly a few days before cutting, and wait until the surface of the soil is slightly dry before cutting the sunflowers. After the cuttings are completed, watering is not allowed. Sunflower cuttings must be watered less, and the topsoil can be sprayed with a watering can every few days, but never watered thoroughly. The failure of sunflower cuttings is mostly caused by excessively wet soil. Remember to keep the soil slightly moist.

Fourth, maintaining a temperature of 20-30 degrees is best for the roots of sun peanuts.

The leaves of sunflowers will wilt three or four days after cuttings. This is normal and there is no need to worry. Do not water them at this time. If the soil is too dry, you can use a spray bottle to wet the topsoil. After about a week, the leaves of the sunflowers will slowly become emerald green and shiny, which proves that the sunflowers have grown new roots and are alive.

The key points of sunflower management after survival are warm and ventilated environment, sufficient light, and strict control of watering. The cause of sunflower death is basically too much water.
