Sow my china aster

the China aster likes soils a bit poor, but will not tolerate moisture! Plant it in full sun, in well-drained soil, neutral or alkaline and sheltered from strong winds. In a vat or planter, use a mixture of potting soil and soil filling the bottom of the tray with a draining layer (small stones, gravel). You can sow the daisy queen in a bucket or under a shelter from March-April. You can also sow them directly at the end of the frosts, in April or May for late flowering at the end of August.

Thin out my china aster

After emergence, thin the seedlings, keeping only one out of two or three - the most vigorous plants!

Dibble my china aster

When they have 4 or 5 leaves, you can transplant the seedlings into individual buckets and pinch their ends to force them to branch out.

Plant my china aster

Transplant outside after the last frosts, as early as May or June. For large varieties with very double flowers - and heavy! - the setting up of stakes makes it possible to prevent that the wind or the rain does not break the flower stalks.

Water my china aster

The China aster fears excess water! Water the potted plants every 3 or 4 days. In the open soil, water only to maintain a cool soil, but never soaked. Avoid wetting the leaves to avoid an attack of powdery mildew.

Take care of my china aster

The China aster prefers poor soils, no fertilizer is needed most of the time. If you find your potted plants a little weak, bring a liquid fertilizer every 15 days during flowering.

Prune my china aster

If you want to prolong the blooming period late in the season, deadhead once or twice a week ! Another option is to make bouquets for the dinner table !

Check on my china aster

Every season brings a different problem! Callistephus chinensis can be attacked by powdery mildew or Fusarium wilt, and by pests such as aphids. First, aphids! If treated early, a solution of baking soda - 5 grams in 2 liters of water, with a little soap - might be a good solution. Powdery mildew in full summer, will cause a white felting on the leaves and the flower buds. Remove affected parts as soon as you spot them! Fusarium, a microscopic fungus found in the soil, causes dry rot, browning of the stem, and eventually drying out of the whole plant. And there's not much to do but to tear off and burn the remains.

Remove my china aster

At the end of the season, remove annual plants like China aster.
