Aglaonema 'Cintho King'

Aglaonema 'Cintho King' grows larger than many compact Chinese evergreens, with long green leaves marked by pale silver-green centres and deeper green margins. Firm petioles lift the foliage above the pot, giving the plant a wide, upright outline.

The larger leaves and rounded crown need more space than compact tabletop Aglaonema cultivars. It gradually builds height and width as new leaves rise from the short crown.

Cintho King size and leaf pattern

• Fuller medium-sized Aglaonema with upright, bushy growth
• Large lance-shaped leaves with silver-green centres and darker edges
• Pale petioles that hold the foliage clearly above the pot
• Rounded crown that gains width as new leaves form
• Filtered light reduces scorch marks, and measured watering keeps the lower roots from sitting wet

Large leaves and upright structure

Aglaonema 'Cintho King' develops broad, elongated blades with a central silver-green field following the midrib. The stems stay short while the foliage supplies most of the plant’s height and spread.

Aglaonema is a tropical Asian aroid genus from warm, shaded forest habitats. Indoors, stable warmth keeps the petioles firm, filtered light reduces scorch marks, and a draining root zone prevents the lower roots from staying wet.

Older basal leaves may fade as fresh growth forms above them. Removing ageing leaves cleanly at the base keeps airflow around the lower stems and leaves room for new growth.

Care needs for Aglaonema 'Cintho King'

• Light: Place in bright filtered light or steady medium light. Large pale areas mark easily in harsh sun, especially close to south-facing glass.
• Watering: Water thoroughly once the top few centimetres of substrate feel dry. A larger plant often needs slower watering so the root ball moistens evenly.
• Substrate: Use a free-draining foliage mix with fine bark, coco coir or peat-free fibre, plus perlite, pumice or other mineral particles.
• Drainage: Keep the plant in a pot with drainage holes and remove standing water after watering. A stable outer pot can help balance the larger leaves.
• Temperature: Maintain 18–26 °C so new leaves keep emerging and petioles stay firm. Keep the pot away from cold floors, draughty doors and cold window glass.
• Humidity: Moderate humidity reduces stuck folds, torn edges and crinkling on new leaves, especially in dry heated rooms.
• Feeding: Use a balanced houseplant fertiliser at reduced strength during active growth. Too much fertiliser can brown the leaf edges and damage fine root tips.
• Repotting: Repot when the plant becomes top-heavy, roots circle the pot or the substrate breaks down. Repot during active growth so new root tips replace damaged ones more quickly.
• Pruning: Remove old yellowing leaves at the base so damp leaf material does not sit against the lower stems. Very tall stems can be cut and rooted as node cuttings.
• Acclimation: After shipping or a major move, warmth and filtered light help new leaves start emerging again, while checking the root ball before watering keeps stressed roots from sitting wet.
• Propagation: Division is easiest on mature clumps with several shoots. Each section needs roots and an active crown.
• Semi-hydro substrates: Plants with firm active roots adapt more safely to mineral substrates; weak or damaged roots can rot during transition. Keep the reservoir low at first and check for soft, brown or sour-smelling roots during the transition.

Cintho King stress signals

• Dark soft patches after cold exposure: Move the plant to stable warmth and keep the substrate on the drier side until the damaged areas are clear.
• Yellowing lower leaves: Check the leaf age first. Multiple yellow leaves together point to wet substrate, poor drainage or a cold root zone.
• Brown tips and margins: Review watering pattern, fertiliser concentration and humidity. Large leaves brown at the tips and margins quickly when watering, humidity or fertiliser strength changes sharply.
• Leaning crown: Rotate the pot regularly and check whether the plant has become root-bound or top-heavy.
• Sticky marks or fine webbing: Inspect petiole bases and undersides for pests. Clean the leaves and isolate the plant before treatment.

Handling the larger crown

Leave enough space around Aglaonema 'Cintho King' for the broad blades to spread. Wipe dust from the leaf surface and remove ageing foliage at the base so crowded leaves do not trap damp, hidden debris near the stems.

Cintho King safety note

Keep Aglaonema 'Cintho King' away from pets and small children. The leaves and stems contain insoluble calcium oxalate crystals, which can irritate the mouth, tongue and throat if plant tissue is eaten. Gloves are sensible when pruning or dividing if your skin is sensitive to aroid sap.
