The germination rate can be increased by keeping the seeds cool at low temperature of 2-5 ℃ for 3 days. When the temperature is 13-15 ℃, the seedlings can emerge in 7-9 days. When the seedlings grow 6 straight leaves, they can be planted in pots with soil balls. Cutting, we need to choose a 10 cm or so goldfish grass to pick the heart, retain the lower 5 or so true leaves, the top of all the true leaves, planting.

4. Control of light and temperature. Goldfish grass likes the sun and can also grow in semi-shade. Sufficient light can make the goldfish grass grow vigorously, and the flowers grow more brightly. Under the semi-shade condition, the flower branches grow taller and the flowers are lighter in color. We can replenish the light to make it blossom in winter. But it can not bear the heat, so we should pay attention to avoid the heat in summer. in the process of planting, the temperature can be kept at about 20-30 ℃ in the daytime and 15 ℃ at night.
