Attention

Dahlia, also known as Dahlia, Dahlia, Tianzhu peony and so on, is a perennial herbaceous bulbous plant with various colors and shapes, and is one of the most famous flowers in the world. Dahlia has a long flowering period, large diameter, many flowers, and especially large flowers, so it is liked by many flower friends.

1. Soil: the choice of soil is more important. If the soil is completely suitable for plant growth, the plant growth is relatively healthy and exuberant. Otherwise, the plant will be thin and sickly. Dahlias like a loose soil environment. Personally recommend sand and humus. The nutritious soil after maturity is also good. If it is planted in the ground, it is necessary to dig and set up drainage ditches in time and do a good job of drainage.

2. Duration of light: dahlias should be placed in a sunny place. Dahlia likes light and is not tolerant to shade. If it is placed in a shaded place for a long time, it will have poor growth, weak roots, thin leaves and thin stems, light flowers, and even can not blossom. When the temperature is below 30 degrees, it is best to bask in the sun as much as possible, if you can bask in it all day. In this way, the plants are strong, and the flowers are large and plump; when the temperature is above 35 degrees, you should do a good job of shading in time to avoid exposure, and you can use the sun in the morning or evening.

3. Watering and fertilization: the leaves of Dahlia are hypertrophic and sensitive to water demand. Lack of water will wilt the leaves, and water will rot the roots. Just keep the soil moist. Never let the soil be mushy for a long time. When watering the beam, move it to the cool tuyere in time. For fertilization, keep the balance of nitrogen, phosphorus and potassium fertilizer. The ratio of nitrogen, phosphorus and potassium was adjusted appropriately at seedling stage and flowering stage. I am lazy and use a proportion from beginning to end.

4. Pruning: with the passage of time, the dahlia plant is getting bigger and bigger, we can prune the branches according to the actual situation. Potted friends can consider the "second compound flower". After blooming once in the first half of the year, in September, you can cut off part of the stem, leaving only two or three nodes, so that new buds will sprout in autumn and beautiful and bright flowers will bloom in October. It blossoms twice a year.

When you see such a beautiful dahlia, please plant one if you like.
