But raising it well is also an issue that flower friends are very concerned about, and watering is a very important point in breeding.

How to water loose-tailed sunflower (how often)

1. Spring and autumn: the two stages are similar. The temperature is also similar, and the growth rate is also similar. Therefore, the frequency can be controlled at about once a day.

2. Summer: this season is the time to grow most vigorously, evaporate quickly, and need the most water. So sometimes it needs to be watered twice a day. However, although there are many times, the amount of water should not be too much. As we said above, do not accumulate water.

Winter: this is the time when the least water is needed. At this time, there is generally no certain frequency of water supply. It can not be watered, or it can be judged according to the dry and wet state of the soil. If the soil is really dry, it can be watered a little.

What if the leaves of sunflower turn yellow?

1. Soil discomfort

Indoor potted sunflower should be planted in acidic soil and sandy loam. The absorption function of the root system of loose-tailed sunflower is not good, resulting in yellow leaves.

2. Improper transplantation

When potting, it is necessary to remove the outer part of the root system, but the outer root system is the main root system of root respiration. if it is damaged by improper operation, the plant nutrition supply can not be supplied, and the plant will gradually gaunt and die. And the sign of death is that the leaves turn yellow and droop.

3. Improper watering

Loose-tailed sunflower is higher, and the nutrients needed by leaves depend on root transport. Proper watering can quickly absorb the roots and keep the leaves green, but if the basin soil is too wet, it will affect the root respiration, affect the root water absorption, and directly cause the leaves to yellowing.

4. Humidity discomfort

The growth of loose-tailed sunflower needs higher air humidity, and when the air is too dry, the leaves will slowly turn yellow. Water should be sprayed on the leaf surface and the surrounding environment 3-4 times a day throughout the growth period to increase air humidity. However, watering should be stopped after dormancy (after winter).

5. The sun is too strong

The growth of sunflower needs plenty of sunlight, but it needs proper shade from May to September. During this period, excessive light can easily lead to plant leaf burns, which is what we often call sunburn. The leaves appear yellow spots and become scorched and yellowed. Over time, the whole plant will wilt. So in summer, the plants should be kept under shade sheds or big trees to avoid direct sunlight.

What if the root of the sunflower is rotten?

1. Overwatering

In the cultivation of loose-tailed sunflower, watering must be appropriate, to meet the needs of loose-tailed sunflower growth, watering to keep the basin soil moist, but do not have stagnant water, this can prevent the phenomenon of rotting roots.

2. Excessive fertilization

Too much fertilization is also one of the reasons leading to rotten roots of plants, too much fertilizer, it is easy to lead to soil problems, when breeding loose-tailed sunflower, we must pay attention to the growth habits of loose-tailed sunflower, fertilization is not too much, too much will not promote the growth of loose-tailed sunflower, but will have the opposite effect.

3. Disease

Sunflower has rotten roots, which may be due to root rot. Therefore, when raising loose-tailed sunflower, we should pay attention to destroy the withered leaves of loose-tailed sunflower in time in winter, so as to avoid germs overwintering and make loose-tailed sunflower rot.

What if the leaves of sunflower droop?

1. Replenishing light and watering

Move the loose-tailed sunflower to the ideal place for maintenance, and if you encounter continuous rainy days, you can make up the light manually to ensure sufficient sunshine.

Timely watering, loose-tailed sunflower leaves drooping after watering can restore the original state.

2. Increase temperature and control fertilizer

Move the sunflower to a warm place, which can appropriately increase the indoor temperature in winter. Control the amount of nitrogen fertilizer application, and appropriately increase the application of phosphorus and potassium fertilizer to ensure adequate nutrients.

In fact, watering times and watering measurements can not be generalized, not only according to its own growth habits, but also combined with the specific season and the actual environment around it, so florists need to make some efforts to raise it well.
