China asters begin to bloom with short days. Days start shortening from the end of June, so China asters bloom most beautifully towards the end of July, in August, and in September. Therefore, China asters are associated with high summer and autumn.
It is ideal to sow China asters in April and transplant the seedlings out into beds after the last frosts (mid-May); you will harvest the first flowers towards the end of summer.
We recommend starting China asters indoors; direct sowing into the bed will not work.
Sow 1 seed per cell of the plug tray. Sow on the surface of the substrate and cover with a layer of vermiculite. Vermiculite helps maintain sufficient moisture for seed germination but also lets light through, which China asters need to germinate.
Until the first sprouts emerge, it is necessary to water only from the bottom by placing the tray in a dish with water and letting the water wick up. You can also water from the top, but use only the finest misting, otherwise you will wash away the sown seeds.
China asters need a relatively high temperature of 20 - 22 °C to germinate. Seeds germinate in roughly 7 - 10 days and spend 4 - 5 weeks in the tray before growing into proper seedlings.
We recommend not keeping China asters in the tray too long, nor transplanting them into small pots; you get the best result if you transplant China asters from the tray straight into the bed.
Even though China aster seedlings can handle light frosts (-6 °C), there is no need to rush, and it is plenty sufficient to sow China asters during April and transplant them out after the last frosts.
Do not pinch China asters; they will branch naturally. China asters are grown quite densely; we plant them at a spacing of 12 × 12 cm.
They thrive in humus-rich soil; before planting, you can work mature compost into the beds. Choose a sunny location for them.
Attention: do not grow China asters in the same place as last year. Always try to find a new location for China asters and return to the original spot only after 2 - 3 years.
China asters suffer most often from fusarium wilt, so we recommend either (1) choosing China asters that are resistant, such as Matsumoto White, Matsumoto Pink, or Matsumoto Apricot, or (2) always trying to plant China asters in a new place and returning to the original one only after 2 - 3 years.
If you are a professional and grow China asters for cutting, we recommend support, or netting, through which the China asters will grow. Without support, it may happen that stems will be bent and otherwise twisted. For beautifully straight stems, netting is a necessity.
The information given is based on our experience, please use it as a guide only. Times may vary depending on the season, climate, location, sowing and transplanting dates and possibly also the conditions in the greenhouse/greenhouse. We always recommend testing how the plant performs in your conditions. Please do not take this as a guarantee.
