Culture methods and points for attention of hibiscus flower

Soil: River sand, perlite, rotten leaf soil and peat soil can be used in equal proportion. Lighting: hibiscus flowers need to ensure more than 4 hours of light every day, proper shade in summer. Temperature: the suitable temperature for growth is 18-28 ℃. Watering: keep the soil moist during the growth period, watering every 3 days in spring and autumn, watering every day in summer, and spraying water to the leaves. Fertilization: fertilization is needed in germination stage, budding stage and flowering stage. Pruning: spring and autumn.

I. Culture methods of hibiscus flower

1. Select soil

Like to cultivate in loose, fertile slightly acidic soil, you can use river sand, perlite, rotten leaf soil, peat soil, according to the proportion of 1 to 4, if not, you can directly use sandy loam for culture.

2. Sufficient light

In the growth process of hibiscus flowers, it is necessary to ensure at least 4 hours of light every day. Sufficient light is beneficial to the lasting flowering and colorful flowers of hibiscus flowers. Due to the strong light in summer, proper shading is needed to avoid the withering of plants due to lack of water. Generally, hibiscus flowers can be cultured in places with sufficient scattered light.

3. Suitable temperature

Hibiscus is relatively hardy, but it likes to grow in a warm environment, and the suitable growth temperature is 18-28 ℃. In summer, when the temperature exceeds 35 ℃, the plant will begin to enter a semi-dormant state, which needs shade and cooling and proper ventilation.

4. Timely watering

The main results are as follows: (1) the watering times and water quantity of hibiscus flowers need to be determined according to different seasons, the temperature and humidity of different seasons are quite different, and the soil needs to be kept moist during the growth period.

(2) the amount of water watering in spring can be increased appropriately, and it is necessary to keep the basin soil moist during this period. The temperature in spring and autumn is more suitable for plant growth. Generally, the water can be watered once every 2-3 days, and the hot weather in summer can be watered once a day. It can spray water to the ground and leaves, which is helpful to increase air humidity and promote the leaves to grow green.

5. Appropriate amount of fertilizer

Hibiscus flowers according to different growth periods, appropriate application of phosphorus fertilizer, potassium fertilizer, nitrogen fertilizer, is conducive to promote the robust growth of plants, the general fertilization stage is germination stage, budding stage, flowering stage.

6. Pruning in time

We can choose to prune the plants in spring and autumn, cut the plants short in April, and strengthen fertilizer and water management, which is conducive to promoting new shoots and making flowers and leaves grow luxuriantly.

II. Matters needing attention in the culture of hibiscus flower

1. Pay attention to humidity

Hibiscus likes to grow in a humid environment, so it is not resistant to dryness. during its growth, it needs to maintain a humidity of about 60% Murray 70%, which is conducive to dark green and glossy leaves. It should not be placed in a place accessible to heating and air conditioning in winter to avoid wilting and withering of plants caused by air drying, and should not be sprayed on flowers when spraying water, so as to prevent flowers from withering ahead of time. The water temperature should be the same as room temperature.

2. Pay attention to the temperature

Hibiscus flowers are not resistant to severe cold or high temperature, so it is necessary to strengthen conservation in summer and winter, plants can be moved into indoor breeding in summer and winter, proper water spray and ventilation are needed in summer, and timely ventilation and cold protection are needed in winter.

3. Pay attention to watering

Hibiscus flowers in summer, to regularly spray water around the plant to cool down, and pay attention to the amount of water, hibiscus flowers are more drought-resistant, generally can be watered every 10 days or so.

4. Pay attention to fertilization

After the Beginning of Autumn, hibiscus flowers began to enter the vigorous growth period, during which appropriate amount of phosphate fertilizer and potassium fertilizer can be applied. If overgrown plants are found, calcium superphosphate or plant ash extract can be used instead, which is beneficial to inhibit plant overgrowth and promote flower bud differentiation. Bud pregnancy and flowering.

5. prevention and control of diseases and insect pests

The common diseases and insect pests of hibiscus flowers are powdery mildew, which mainly harms plant flowers, fruits, leaves and other organs. You can choose to spray 1000-fold solution of 70% methyl topiramate or 1000-fold solution of 50% carbendazim in the early stage of the disease.
