Your plug tray
Plugs are small and dry out fast. Water on arrival, keep in bright light, and harden off a week before planting. Pot 72-cell plugs into 4 in pots or plant directly once rooted. Pinch once when 6 in tall.

New England Aster · Symphyotrichum novae-angliae
New England aster wants full sun and moist, fertile, well-drained soil. Pinch it in spring for a bushier plant and late-season blooms for pollinators.

When it arrives
Plugs are small and dry out fast. Water on arrival, keep in bright light, and harden off a week before planting. Pot 72-cell plugs into 4 in pots or plant directly once rooted. Pinch once when 6 in tall.
Spring or early fall.
Crown at soil level, same depth as it grew.
2-3 ft apart for airflow; it's a large clump.
Moist, fertile loam; tolerates clay · pH 5.5–7.5
Fix-it tip: Add compost to sandy soil to hold moisture. Clay is fine as long as it doesn't stay waterlogged.
Full sun (tolerates part shade).
Shade causes leggy stems, fewer flowers, and more mildew.
Don’t give up on it
Shoots appear in mid spring. Plants look like green leafy stems all summer and don't bloom until late summer to fall, so be patient.
Divide if needed; pinch stems in late spring.
Water in drought; watch for mildew.
Enjoy blooms; leave seed heads for birds.
Cut back or leave stems standing.
First season: Water weekly through the first summer if rain is short.
After that: Water in dry spells; drought stress causes lower leaves to brown and drop.
Light. Compost in spring; too much nitrogen gives floppy stems.
Pinch or cut stems back by about half before early July (in the North) for bushier plants. This delays bloom slightly. Cut back in late fall or leave for winter birds.
Every 2-3 years in spring to keep it vigorous.
Very cold hardy. Leave stems for wildlife or cut back after frost.
Lower leaves often brown in heat or drought; plant shorter perennials in front to hide them. Powdery mildew is common in humid weather.
White powder on leaves late summerLikely cause: Powdery mildew
What to do: Space for airflow, thin stems in spring, and water at the base.
Stems flop openLikely cause: Not pinched, or too much shade or nitrogen
What to do: Pinch in late spring; stake tall types.
Bare, brown lower stemsLikely cause: Drought stress (normal to a degree)
What to do: Water in dry spells; plant low perennials in front.
Bare, brown lower stems mean drought stress. Yellowing and rot at the base mean too wet.
Not listed by ASPCA; no known toxicity reported. Discourage pets from chewing any garden plant.
Deer: somewhat resistant · Rabbits: susceptible

Possible, with care · 3 gallon+
Large, thirsty plant; possible in a big pot with frequent watering.
Outdoor plant
Needs full sun and winter dormancy outdoors.
No chill needed
Flowering is triggered by shortening days in late summer; young plants usually bloom their first fall.
Plugs from the tray
3–4 inch pots for 3–5 weeks, until roots hold the soil
Garden bed or a 3 gallon potTime to move up? Slide the plant out: if white roots wrap the outside of the soil, it’s ready for the next size.
Planting with lavender
Plant it near your lavender
Shares full sun but wants more water and richer soil. Plant behind or beside the lavender bed; its fall purple blooms carry pollinators long after lavender finishes.
