Australian sundew Care (Drosera aliciae)

This compact sundew needs bright light to form strong red coloration and sticky traps.

• Provide 4–6 hours of direct morning sun plus bright, filtered light for the rest of the day; in hot regions, shield from harsh sun after 1–2 pm.
• Tolerates light partial shade, but leaves turn greener and traps weaken if total direct sun falls below about 3 hours daily.
• Outdoors, give maximum sun from late fall to early spring; in summer, use 30–40% shade cloth or dappled light to prevent leaf scorch.

This bog species requires consistently wet conditions and low-mineral water.

• Use rainwater, distilled, or reverse-osmosis water; avoid tap water unless tested below 50 ppm minerals to protect Drosera aliciae roots.
• Keep the soil saturated, not soupy; trays can hold 0.5–2 cm of water, allowing the surface to just stop glistening before refilling.
• In cooler seasons, reduce tray depth so soil stays moist rather than flooded; pale, limp leaves often signal overwatering, while crisping leaf tips indicate drying out.

This species prefers mild, frost-free conditions with stable, cool-to-warm temperatures.

• Aim for 65–80°F (18–27°C) for best growth, with minimal day–night swings to reduce stress.
• Protect from cold below 35–40°F (2–4°C); frost can kill foliage and damage the crown, so move plants under cover during cold snaps.
• In hot spells above 90°F (32°C), provide light shade, good air movement, and slightly deeper water trays to buffer root temperature and prevent heat stress.

This species prefers consistently moist air but adapts to typical indoor humidity if roots stay wet.

• Aim for 50–70% humidity to keep traps dewy and active for the Australian sundew.
• Tolerates brief drops to 30–40%, but leaves may curl slightly and dew production decreases.
• Increase humidity with a nearby tray of water or grouped plants, avoiding enclosed, stagnant air around foliage.

This carnivorous species needs nutrient-poor, acidic, open soil that stays constantly moist without becoming stagnant.

• Use a mix of 1:1 sphagnum peat moss and perlite or silica sand to provide low nutrients and a loose structure.
• Aim for acidic conditions around pH 4.5–5.5; never add compost, regular potting mix, or fertilizer granules.
• Ensure the mix drains freely yet remains evenly damp by avoiding fine sand or dense materials that compact easily.
• Rinse sand and perlite before use to remove mineral residues that could build up and damage Drosera aliciae roots.

This species is very suitable for container growing when moisture and mineral buildup are controlled.

• Choose a relatively deep pot so the consistently wet mix stays cooler and roots can spread without crowding.
• Use plastic or glazed ceramic containers, which retain moisture more evenly than unglazed clay for this bog species.
• Place the pot in a shallow tray of distilled or rainwater, letting excess drain freely while maintaining a stable water table.

Drosera aliciae gains most nutrients from captured insects, so use fertilizer very sparingly for healthy growth.

• Skip fertilizer for most plants; caring for Australian sundew normally relies on adequate light, pure water, and insects.
• If growth is weak, apply a very dilute balanced NPK (1⁄4–1⁄8 strength) to roots only, never on leaves.
• Feed no more than every 4–6 weeks during active growth in spring–summer, then stop in fall–winter.

Drosera aliciae needs only light pruning to keep the rosette clean and healthy.

• Best time is late winter or early spring, before strong new growth starts.
• Use small scissors or fine tweezers to remove dead, brown, or moldy leaves at the base.
• Cut spent flower stalks near the crown if seed is not wanted, directing energy back into leaf production.
• Avoid cutting healthy sticky leaves, as this reduces photosynthesis and insect capture.

This small sundew grows well in pots but benefits from occasional repotting into fresh, low‑nutrient mix.

• Repot every 1–2 years in late winter or early spring, before vigorous growth resumes.
• Check for crowded rosettes, roots circling the pot, slow growth, or sour-smelling substrate as signs to repot.
• Use a plastic pot with drainage and fresh 1:1 sphagnum peat and perlite or sand, with no added fertilizer.
• Lift the plant gently, keep the root ball intact, water with pure water after repotting, and shade lightly for a few days to limit stress.

This species is commonly propagated to expand a collection or replace older rosettes.

• Divide mature clumps in late winter or early spring, separating small offset rosettes with attached roots.
• Use leaf cuttings on live sphagnum or peat:sand mix, keeping them flat on the surface and consistently moist.
• Maintain bright, indirect light, high humidity, and temperatures around 65–75°F to support rooting and new plantlets.
• Sow fresh seeds on the surface of moist, nutrient-free medium and avoid covering them, as they need light to germinate.

This subtropical sundew dislikes frost and needs protection in regions with cold winters.

• Keep plants above 40°F; prolonged exposure near or below freezing can kill foliage and crowns.
• Grow in containers that can be moved indoors to a bright, cool windowsill or under grow lights in winter.
• Maintain evenly moist, not waterlogged, substrate with pure water, as dry soil increases cold damage risk.
• Do not allow cold drafts directly on the plant, and avoid sudden temperature swings.
