Care Instructions

Look to ensure a distance 8.58 inches (22.0 cm) between China aster seeds when sowing to make sure your seedlings have enough space.

China aster normally grows to a mature height of 70.0 cm (that's 2.27 feet imperial) so ensure you have enough space in your garden for this plant.

Your garden has indoor light - a partial sun position will ensure your plant thrives.

Remember to water moderately.

Try to keep the ph of your soil between the range of 5.1 and 7.5 as China aster likes to be in acidic to alkaline soil.
