How to Grow Monstera Adansonii
Monstera adansonii
Monstera adansonii is a fast-growing trailing or climbing houseplant with distinctive heart-shaped leaves covered in oval holes. It thrives in bright indirect light with high humidity, and benefits from a moss pole or trellis to climb. Keep the soil lightly moist and mist regularly or use a pebble tray to boost humidity. It grows quickly in the right conditions and is an easy choice for shelves, hanging baskets, or a support pole.
Yearly Lifecycle
Care Essentials
Feed monthly with a balanced liquid fertiliser during spring and summer. Reduce to every 6–8 weeks in autumn and stop feeding in winter when growth slows.
Watch For
- Root rot from overwatering (yellowing leaves, mushy roots)
- Mealybug in leaf axils and on stems
- Scale insects (sticky residue, brown bumps)
- Red spider mite in low-humidity conditions
- Yellow leaves from draughts or cold windowsills

☀️ Light
Bright indirect light; tolerates medium light
Thrives in bright indirect light, such as near a north- or east-facing window. Tolerates medium light but growth slows and fenestrations may be smaller. Avoid direct sun, which scorches the delicate leaves.
💧 Watering
Keep soil lightly moist; allow top 2 cm to dry
Water when the top 2 cm of soil feels dry. Reduce watering in winter when growth slows. Always use a pot with drainage holes to prevent waterlogging.
🌱 Fertilizing
Monthly feed in spring and summer
Apply a balanced liquid fertiliser at half strength once a month from spring through summer. Do not feed in autumn or winter.
✂️ Pruning
Prune to encourage bushy growth
Trim back long trailing stems to promote branching. Cuttings root readily in water and can be used to propagate new plants.
🌿 Humidity
High humidity essential — 50-70% ideal
Mist regularly, use a pebble tray with water, or run a humidifier nearby. Brown leaf tips indicate insufficient humidity, which is common in centrally heated UK homes in winter.
Growing Tips
Provide a moss pole or trellis
Aerial roots need support to climb. Without a pole the plant stays bushy and smaller; with one, leaves grow larger and more fenestrated.
Keep humidity high
Mist daily or place on a pebble tray. Central heating drops humidity well below the 50% minimum, causing brown leaf tips.
Fenestrations come with maturity
Young leaves are often unperforated. Holes develop naturally as the plant matures — no action needed.
Prune to encourage bushy growth
Trim long trailing stems to promote branching. Cuttings root readily in water and can be used to propagate new plants.
Pests & Diseases
Pest Red Spider Mite
Identification: Fine webbing under leaves; pale stippling on leaf surface; tiny red or yellow mites visible under magnification.
- Increase humidity — spider mites thrive in dry air.
- Wipe leaves with a damp cloth; spray with diluted neem oil solution.
- Apply a miticide such as bifenazate when infestation is severe.
Pest Mealybug
Identification: White fluffy cottony masses in leaf axils, on stems, and on undersides of leaves.
- Dab individual mealybugs with a cotton bud dipped in 70% isopropyl alcohol.
- Spray with diluted neem oil or insecticidal soap solution.
- Systemic insecticide containing imidacloprid applied as a soil drench.
Pest Scale Insects
Identification: Brown or tan oval bumps on stems and leaf veins; sticky honeydew on leaves; sooty mould may develop.
- Scrape off scales with a soft toothbrush dipped in soapy water.
- Apply neem oil to all surfaces of the plant.
- Systemic insecticide containing acetamiprid.
Disease Root Rot Pythium spp. / Phytophthora spp.
Symptoms: Yellowing leaves, wilting despite moist soil, brown mushy roots visible when repotting.
Treatment: Remove the plant from its pot, trim off all brown mushy roots with sterile scissors, allow to dry briefly, repot into fresh well-draining mix.
Prevention: Never allow the plant to sit in standing water; use a pot with drainage holes; allow top 2 cm of soil to dry between waterings.
Disease Bacterial Leaf Spot Pseudomonas spp.
Symptoms: Water-soaked dark patches on leaves that enlarge and turn brown or black with a yellow halo.
Treatment: Remove affected leaves immediately; avoid wetting foliage; improve air circulation.
Prevention: Water at the base only; avoid misting directly onto leaves in low-light conditions; keep humidity high but air moving.
