The culture method of dahlia and the matters needing attention in dahlia culture

Pruning dahlias need to be pruned in time during the growing season, retain their top buds, and then cut off other axillary buds to make nutrients more concentrated. Matters needing attention in dahlia culture, dahlias need to avoid strong light in summer, stagnant water in the rainy season, and a good ventilated environment during maintenance. this can avoid the occurrence of diseases and insect pests to a certain extent.

Temperature: it is best to keep the temperature between 20 and 25 ℃ for raising dahlias. Light: it is not shady, usually it should be placed in a position with enough light to maintain. Watering: when raising it, we should pay attention to timely replenishment of water, do not let it lack of water. Fertilization: when it is growing, you should fertilize it in time, but do not apply thick fertilizer.

It is suitable to cultivate dahlias at a growth temperature of about 20: 25 ℃, so that dahlias can grow better in a suitable environment, and pay attention to the fact that dahlias prefer light to shade, and sufficient scattered light should be ensured during culture, so that they can germinate flower buds and blossom better.

How to raise dahlias

Soil dahlia in breeding should fully meet its environmental requirements, sandy loam with good drainage is generally allocated to it to meet the needs of nutrient soil, usually using five parts of garden soil, two parts of rotten leaf soil, two parts of sand plus one part of mature organic fertilizer, to meet its soil requirements.

Aquaculture environment: the temperature is controlled between 5-35 ℃ and receives 6 hours of light every day. Water and fertilizer management: water every 3-4 days in spring and autumn. Pruning branches and leaves: when the dahlia is in florescence, trim the lateral buds around the stem and keep only 2-3 buds at the top. Disease prevention: spray carbendazim solution every one month.

Soil selection Dahlia is suitable to grow in loose, humus-rich and well-drained sandy soil. The soil of potted dahlias should be mixed with vegetable garden soil, rotten leaf soil and sandy soil, and an appropriate amount of fertilizer should be added as base fertilizer. Avoid using sticky hardened soil to prevent stagnant water from rotting the roots. Watering method Dahlia likes water but avoids stagnant water, because it has fleshy roots, too much water can easily lead to root rot.

Culture methods and matters needing attention of Dahlia

1. Soil: sandy soil, vegetable garden soil and rotten leaf soil are used as cultivation substrates, and clayey soil should not be used. Lighting: after potting, put the flowerpot in a place with plenty of light to ensure that the light lasts for more than 6 hours every day. Watering: the amount of water should be increased during the growing period, once a day when the temperature is high, and the water should be properly controlled at the seedling stage to avoid dwarfing of the plant.

2. The cultivation methods and matters needing attention of dahlias are as follows: soil dahlias should fully meet its environmental requirements when raising dahlias, sandy loam with good drainage, and generally equipped with nutritious soil to meet the needs. usually use five parts of garden soil, two parts of rotten leaf soil, two parts of sand plus one part of mature organic fertilizer to meet its soil requirements.

3. If it is spring, the weather changes greatly, so keep the soil moist. If it is summer, in order to lower the temperature and increase air humidity, you should spray water 1-2 times a day and water it once around 3-4 p.m. (the amount of water should not be too large). If it is autumn, it should be watered less to avoid excessive growth of flowers, thus affecting the flowering of the following year. If it is winter, the dahlia is dormant at this time, just keep the pot soil a little dry.

How to plant dahlias?

1. Ramet propagation and ramet planting can be carried out after the beginning of spring. First of all, we should prepare the stored root tuber, cut the root with bud, plant it in the soil, and cultivate it normally. If it is planted in this way, it can blossom in autumn. The advantage of ramet planting is that the survival rate is high, economical, simple and convenient, but the disadvantage is that the reproduction coefficient is not too high.

2. There are three main planting methods of Dahlia: split propagation, cutting propagation and seed propagation. Spring is the best time for ramet propagation. Choose a healthy root tuber, split the root with budding eyes, and plant it in the soil. This method has the advantages of simple operation and high survival rate, but the reproduction coefficient is relatively low. In autumn, these roots can blossom.

3. Choose the right soil: Dahlia likes loose, fertile and well-drained loam and hates clay. Potted plants can be made of rotten leaf soil, pastoral soil and sandy soil, and add a small amount of base fertilizer. Suitable temperature: dahlias like a cool environment and do not require a high temperature during the growing period, ranging from 8 to 35 degrees, but the most suitable temperature is between 15 and 25.

How to raise dahlias (how to maintain dahlias to blossom more)

Sandy soil dahlias are suitable to grow in loose and fertile sandy soil, and in soils with good drainage, when cultivating dahlias, two parts of garden soil, two parts of humus soil and one part of river sandy soil can be mixed into cultivation substrates to ensure that the soil has good air permeability and drainage, so that the roots of dahlias can breathe better, and attention should be paid to sterilization and disinfection after soil preparation is completed.

The soil chooses the sandy soil with loose and good drainage as the matrix, which can be prepared by sandy soil, vegetable garden soil and rotten leaf soil to avoid the use of heavy clayey soil. Light (1) after the plant is in the pot, put the flowerpot in a place with plenty of light to ensure that the light lasts for more than 6 hours per day, so that the plant can grow well and produce fuller flowers. (2) if the light is not enough, the root system of the plant will grow poorly and even can not blossom.

Water Dahlia root system is thick and succulent fleshy root, strong gas, so the soil must be loose and breathable, good drainage, if the soil hardening, waterlogging hypoxia, it is easy to cause rotten roots, or even death.
