- ✅ Sow Aster Duchess White seeds indoors 6 weeks after the frost danger has passed, or outdoors after last frost.
- ✅ Set up 3-inch seedling pots inside a drip tray. Load each pot with potting mix up to within 1/2 inch of the pot rim. Add in 1 inch of water to the drip tray, and let the soil in the pots to soak up the water until the soil surface area gets damp, after that empty virtually any remaining water from the tray.
- ✅ Sow aster seeds on the top of the soil surface. Cover the seeds with a 1/4-inch layer of moist soil.
- ✅ Cover the pots with a layer of clear plastic wrap, which preserves moisture till the seeds sprout. Set up the tray of pots in a 70-75 Fahrenheit place that gets indirect light from sun. Asters will germinate in the dark, but they germinate quicker with some light.
- ✅ Take out the plastic wrap when sprouts come out. Move the pots to a spot that gets a minimum of 6 hrs of direct sun light; water the seedlings when the soil surface area dries out. Once the plants produce their 2nd set of leaves, thin the seedlings to ensure that only one aster remains in each pot.
- ✅ Incorporate a 2-inch garden compost layer into the top of 8 inches soil, in a well-draining outdoor bed that gets 6 hours of direct sun light daily. Transplant the asters into the bed at the very same depth they were in their pots, spacing them 18 inches apart.
- ✅ Water aster plants deeply one or two times a week, giving aprox 1 inch of moist each time, make sure that the top 6 inches of soil do not dry. Spread out a 2-inch layer of mulch over the bed to support preserve the soil humidity.
- ✅ Cut off spent blooms, and get rid of any plants that seem unhealthy to avoid the spread of diseases. Spritz the asters with an insecticidal soap if leafhoppers, mites or aphids end up being an issue.

The seeds did ok germinating.
They are growing no flowers yet but over all they grow so have to wait n see.
I have these in three different locations around the house. They haven't bloomed yet, but they are growing strong and I've had a pretty good germination rate. Would recommend.
Very good germination rate on these… we’ve got more than enough seeds left to do another planting next year and possibly more after that depending on how well they hold over in the fridge drawer. Hopefully these will successfully reseed on their own, we’ll see.

The weather was cool and even had some rains after planting them and yet still no sign of life.
The instruction said it will show signs of life within 7-21 days.
Maybe I should have waited till fall or winter but let's see how it goes.
