Detailed explanation of Dutch dahlia cultivation methods

When it comes to dahlia, many people feel that it is an "outdated product". But judging from the sales trend of Dutch dahlias in the past 3 years, this is not the case. "you can always see dahlias in the Netherlands, whether in residential gardens or in various flower magazines," said Kempen, president of Dutch WJKempen Flower Company, which sells about 200000 dahlias a year.

Tuber: transport temperature 5 ℃ ~ 9 ℃, not lower than 0 ℃. Packing quantity according to the specification, a lily plastic turnover box can hold 25 piers and 60 piers.

Planting time: generally in March to April every year, you must wait until the end of the frost period before you can go to the soil. In the south, planting can start in mid-late February.

Planting depth: it is better that the tuber has just disappeared into the soil surface, and the covering soil layer should be about 3cm.

Soil requirements: Dutch dahlias can grow in any type of loose soil. The point is that the soil must be able to provide nutrients, be permeable and not be too dry. The ideal pH value is 6-7. If it is too acidic, lime can be applied.

Planting location: the planting location should ensure that Dutch dahlias always receive enough light. Do not plant Dutch dahlias under trees or in shady places. Dutch dahlias are very suitable for growing in open-air areas. They can withstand the sun all day. Therefore, if the Dutch dahlia is planted in a high temperature and unventilated environment, it will cause the plant to grow too high, make the stem weak and blossom less.

Planting density: generally 6 piers per square meter. Generally, there are 6 piers per square meter.

Watering: be sure to water enough Dutch dahlias. The soil should always be kept moist. When the plants are fully grown, if the weather is too hot, the leaves will evaporate a lot of water, especially the higher varieties. Lack of water will lead to slow growth, few flowering and yellow leaves. Dutch dahlias require a large amount of fertilizer. The soil should be fertilized correctly before planting, and sometimes even need to go to the laboratory for soil sampling and analysis. Organic grain fertilizer can be added before planting. During the plant growing period, replenish some balanced nutrients regularly. Such as granular NPK12-10-18. You can sprinkle a large number of particles around the plant, or you can dissolve the nutrients in water and irrigate the plant, paying attention to the solution that is not too strong. Grain fertilizer is applied every four weeks, and irrigation nutrient water solution is applied every one to two weeks. Make sure the plants are in good condition and continue to grow new buds and flowers. You can also consider using some experiments to find out how much nourishment Dutch dahlias need.

Growth temperature: the growth temperature of Dutch dahlia is between 15 ℃ and 25 ℃. They can't stand frost, so don't plant outside until the ground frost is over. This is the same for cut flowers and conventional plant production. If you are planting tubers, you can start planting after the local frost is over, and the temperature begins to rise when the buds break through the soil 2 to 3 weeks later.

Further cultivation: the plant height of the common variety is 25~175cm. Taller Dutch dahlias should be supported, especially when there is a strong wind. Dutch dahlias can be tied to the support strip. The garden can be fixed with special plant support devices, such as plastic rings, and its visual effect will be better. If you want the plant to be dense and multi-branched, you can prune the buds to retain only 2 to 3 pairs of leaves, so that more flower branches will be produced when the leaf buds develop. When the flowers fade, first pick off the withered flowers, with the same method, will achieve the same effect. Pruning will stimulate the growth of new buds. In order to have more Dutch dahlias and prolong their flowering period, growers need to often pick off past flowers during their flowering period. the more they are removed, the more new flowers will grow, which is why withered flowers should be removed. Removing the withered flower and pruning the stem to the next leaf bud is especially important for a single Dutch dahlia, which, if not, will soon produce seeds and use the plant's energy reserves and nutrients to grow pods, during which time, plants will not grow new buds and flowers.

Storage of tubers: Dutch dahlias can't stand the cold winter. After flowering, growers must dig up the tubers before the first frost. Do not damage the tuber, cut the tuber above to 5cm, you can leave a little soil on the tuber. Dry the tuber naturally for a short time, then store it in a dry, frost-free, dark and unventilated place with a temperature of 6 ℃ ~ 8 ℃. Please remember to label the variety or color. The stored tubers should not be too wet or dry, and wrinkles can be seen on the general epidermis.
