A very popular 7 cm double flowered aster in a blend of clear soft colours. Ideal for mass planting in borders or landscaping.
Plantation : Sow the seeds 6 weeks before the last frost. Keep the temperature between 18-20 °C. Germination time is between 10 and 14 days.
Soil : Indoor: A well-drained, porous sowing media is best to prevent overwatering. Outdoor: Fertile, well-drained soil.
Culturals practices : Step 1: plow the soil about 30 cm (12 inches). Add an equal part of potting soil and mix well. Dig a hole approximately the same length as the container and about 1 ½ to 3 times the width. Step 2: slightly squeeze the container, tap out the plant, and delicately free the roots. If the roots are too dense, liberate the fibers by inserting a knife or a transplanter. Separate the roots carefully, then place in the hole.* Good to know: Use an organic bone meal or a «soil activator» when transplanting to stimulate root development. Follow the instructions for use on the package. Fill up the hole with garden soil. Slightly press the soil around the base of the plant to favor the contact between the roots and the soil. Water regularly every 2 or 3 days until the soil is well compacted.Note: These plants appreciate a neutral or slightly calcareous soil, well fertile and drained and require a good sunny location. Copious watering will be necessary twice a week during the dry season but be careful not to water the foliage because the Aster are sensitive to powdery mildew. Remember to remove faded flowers as you go to prolong flowering and avoid weakening the plant.
