It is recommended to use hole pots or nursery pots for seedlings of four seasons. Do not directly sown four seasons flowers in the ground for raising seedlings. Direct sowing in the ground will increase the spread of soil diseases and insect pests. The low water and humidity of the ground temperature are not easy to control, which will affect the germination rate. , Four seasons grass flower hole pot seedlings is also convenient to calculate the germination rate of the seedling substrate. The seedling substrate requires loose soil and good air permeability to retain water and fertilizer, clean, disease-free and good fertility. Commonly used substrates include peat soil, coconut bran, perlite, Vermiculite is generally mixed, such as peat soil 85% plus perlite 10% and vermiculite 5%. The peat should not be too fine. The diameter of perlite particles is 3 to 4 mm. The diameter of vermiculite particles is 3 to 5 mm. The ideal substrate Some fertilizers can be properly added to the medium. Most seeds germinate well on the substrate, but the pH value of a bunch of red, geranium, marigold and maidenhair grass needs to be 6.2-6.5. The temperature of the four season grass flowers is appropriate according to the requirements of the specific four season grass flower varieties. Temperature, the germination temperature of most seeds is between 20-25°C. Too high or too low temperature will directly affect the germination rate of seeds. Humidity: moisture management after sowing is very important. Winter seedlings are cultivated at night when soil temperature is low. Therefore, in the seedling period, there is no need to add water or less water. If the soil temperature is high, in the seedling period, water should be sprayed according to actual needs. During summer seedlings, the water evaporates very quickly. Water must be added at any time according to the actual situation. Washing can use the method of soaking basin to replenish water.
