Dwarf Mouse-ear Tickseed Care (Coreopsis auriculata 'Nana')

Coreopsis auriculata 'Nana' flowers best in bright outdoor conditions with several hours of direct sun.

• Provide 6–8 hours of direct sun daily; morning sun with light afternoon shade helps prevent leaf scorch in hotter regions.
• Plant in a spot with at least 4 hours of direct morning light if full sun all day is not available, as Dwarf Mouse-ear Tickseed tolerates partial shade but blooms less.
• Watch for weak, floppy stems and sparse flowers as signs of too little sun, and for crisped leaf edges as a sign of excessive, intense afternoon sun.

Coreopsis auriculata 'Nana' prefers moderately moist but well-drained soil and does not like prolonged wetness.

• Water when the top 3–5 cm of soil feels dry, soaking the root zone once, then letting excess drain away fully.
• Reduce watering frequency in cool or rainy weather and during winter dormancy, but avoid letting the soil stay bone-dry for more than a few days in hot spells.
• Use fast-draining soil and watch for yellowing, soft stems as a sign of overwatering, or drooping, crisp leaves and stalled growth as signs of underwatering.

This compact coreopsis is a hardy perennial suited to a wide range of outdoor temperatures.

• Active growth and flowering are strongest at 65–80°F (18–27°C), with good performance in typical spring and early summer conditions.
• The plant is cold-hardy in the ground, tolerating winter lows near 0°F (−18°C) or below in many climates, dying back above ground but regrowing from the crown.
• It copes with summer heat up to about 90–95°F (32–35°C) if soil moisture is maintained, but prolonged extreme heat or sudden hard frosts can damage foliage and flower buds.

This species is adapted to outdoor conditions and does not have special humidity requirements.

Coreopsis auriculata 'Nana' prefers moderately fertile, well-aerated soil that drains quickly yet does not dry out instantly.

• Use a sandy or loamy soil with 20–30% compost to provide structure and moderate nutrient levels.
• Ensure sharp drainage by blending in coarse sand or fine gravel, especially in heavier native soils.
• Aim for slightly acidic to neutral pH, around 6.0–7.0, for the most reliable growth.
• Avoid compacted clay, waterlogged spots, or thick peat mixes that stay wet and exclude air from roots.

This species grows well in containers when given stable, free-draining conditions.

• Choose a wider, shallower pot to accommodate its spreading habit and prevent the plant from becoming top-heavy at the rim.
• Use a rigid, heavier container material if exposed to wind so the plant’s spreading foliage does not tip the pot.
• Raise the pot on feet or bricks so drainage holes stay clear and runoff leaves the container quickly after watering.

Coreopsis auriculata 'Nana' needs only light feeding in average garden soil.

• Apply a thin layer of compost or well-rotted manure around plants in early spring to support flowering.
• Use a balanced slow-release fertilizer (around 10-10-10) once per year in spring if growth seems weak.
• Dilute liquid fertilizer to 1/2 strength for container-grown Dwarf Mouse-ear Tickseed during the growing season, every 4–6 weeks.
• Stop feeding in late summer to early fall so new growth can harden before winter.

Coreopsis auriculata 'Nana' benefits from simple pruning to maintain compact form and repeat bloom.

• Deadhead spent flower stems through summer using clean scissors or hand pruners to extend blooming.
• In late fall or very early spring, cut back old, dead, or damaged stems to just above the basal foliage.
• Thin crowded or weak shoots to improve air circulation and reduce foliar disease risk.
• Lightly shape clumps after the main bloom flush to keep mounds low and dense.

This compact perennial is usually grown in the ground, with transplanting more relevant than frequent repotting.

• Transplant or divide every 3–4 years in early spring or early fall when clumps become crowded or bare in the center.
• Move plants when growth slows despite good care or when roots fill and circle a container.
• Dig widely around the root mass, lift gently, and replant at the same depth in well-drained soil.
• Water thoroughly after transplanting, then keep soil evenly moist for 1–2 weeks to limit root stress.

Coreopsis auriculata 'Nana' is commonly propagated by division and sometimes by seed for larger plantings.

• Divide mature clumps in early spring or early fall, ensuring each division has several shoots and a healthy root section.
• Replant divisions promptly in well-drained soil, water well, and keep evenly moist until established.
• Sow fresh seeds in late fall or very early spring outdoors, where natural cold helps break dormancy.
• Provide full sun and moderate moisture for both divisions and seedlings to encourage strong, compact growth.

This hardy perennial usually needs minimal winter care in most temperate climates.

• Established plants tolerate typical frosts in USDA zones where they are recommended.
• After hard frost, cut back dead stems to tidy the plant, leaving the crown slightly above soil level.
• Apply a 5–7 cm layer of mulch around, not on top of, the crown to moderate soil temperature swings.
• For container-grown plants in colder areas, move pots to a sheltered, unheated but frost-free spot.
