2, artificial methods to promote germination, is to use sandpaper, or nail clippers on the nail file, carefully sanding the shell of the seed (outside of the germ area, randomly select a point can be). To grind until the shell is worn through, can see the seed flesh inside the seed until.
3. Soak the ground seeds in water for 2 days until they swell.
4. Place the soaked seeds on the surface of the soil of your choice and gently cover with a thin layer of fine soil. Water well with a fine spray bottle (too much water will wash the seeds out of the soil surface) and place the pot outdoors in a well-ventilated area with diffused sunlight. Keep the soil just slightly moist.
5. After this treatment, the seeds will germinate more easily.
Additionally, the sowing time, it is best to choose in the late spring or early fall, do not sow in winter, hot summer.
