After 5-6 weeks, blue flowers can be transplanted into pots in 10-15 cm pots, fan-shaped flowers can be transplanted into pots in 7-11 cm pots, and hybrids can be transplanted in 11-16 cm pots. Twice transplanting is beneficial to the quality of the plant.

two。 Medium: the cultivation medium needs to be well drained, and the soil content in the substrate is about 15%. About 15% organic matter (such as wood fiber and bark) can be added, and 1 to 1.5kg of fully balanced fertilizer and 1 to 2kg of slow-release fertilizer, iron chelate and micronutrient elements should be added to each cubic meter of substrate.
