How to hydroponically cultivate and maintain primroses?

Primroses, alias primroses, New year flowers. Belongs to Primula (or Primrose). Primroses (pictured) are perennial herbs with persistent roots, which are often cultivated in 2012. The plant is low, the tallest is less than 50cm, and the popular horticultural hybrids become more dwarfed in recent years. The stem is extremely short. Leaves basal in clusters, elliptic or ovoid, slightly wrinkled, margin shallowly notched. Umbels capitate, drawn from the base of leaf clusters. Corolla funnelform or salverform, divided. There are many colors, such as red, yellow, purple, white, blue and complex colors. Flowering in winter and spring.

1. Hydroponic method

The main results are as follows: (1) the robust soil culture plants were selected, the sediment and withered roots were removed by root washing, disinfected with 0.1% potassium permanganate solution and planted in a small caliber hydroponic container, and water was added to the 3 roots.

(2) at the beginning of hydroponic culture, the fresh water can be changed every 5 days, and the water can take root in about 10 days. When the plant has a strong growth potential, add the nutrient solution, place sufficient light to maintain, and change the nutrient solution once a week. Place a cool and ventilated place in summer to prevent the scorching sun from shining directly. The room temperature in winter should not be too high, and 10-12 ℃ is the best, which is not only conducive to flowering, but also make the flower color more colorful and the florescence longer. After the flowers withered, the pedicels and residual flowers should be cut off in time, and the dead leaves should be removed.

2. Maintenance guidelines

The main results are as follows: (1) the temperature and light suitable for primrose growth is 10-20 ℃, and the safe overwintering temperature is above 5 ℃. Primroses like plenty of sunshine and grow well in a semi-overcast environment. Summer noon need shade, avoid strong direct sunlight, should be placed in a cool and ventilated place.

(2) adding nutrient solution when fertilizing and hydroponics primroses change water, when the plant shows strong growth, the amount of nutrient solution can be increased.

(3) change the water in the early 2-3 days of primrose growth. After it grows and takes root, it can be changed once in 7-15 days.

(4) Prevention and control of diseases and insect pests. Primroses are not easy to get sick. Healthy plants must be selected before hydroponic culture.
