How to Grow Prayer Plant
Maranta leuconeura
Prayer plants need consistently moist (not wet) soil, high humidity, and warm temperatures above 16°C. Use filtered or rainwater to prevent the brown leaf tips caused by fluoride in tap water. Mist regularly or place on a pebble tray with water to maintain humidity. They fold their leaves upward at night — a healthy and normal behaviour.
Yearly Lifecycle
Care Essentials
Feed monthly with a diluted balanced liquid fertiliser from spring through summer. Reduce to every 6–8 weeks in autumn and stop feeding in winter when growth slows significantly.
Watch For
- Spider mites in dry or warm conditions — very common
- Mealybug in leaf axils
- Root rot from waterlogging
- Brown leaf tips and edges from low humidity or fluoride in tap water
- Leaf curl from cold draughts or dry air

☀️ Light
Bright indirect light; no direct sun
Prayer plants thrive in bright indirect light but are damaged by direct sun, which fades and bleaches the distinctive leaf patterning. They tolerate moderate shade better than most patterned houseplants, but too little light causes the markings to fade and growth to slow. A north or east-facing windowsill with filtered light is ideal in UK homes.
💧 Watering
Keep consistently moist but never waterlogged
Water when the top 1–2 cm of compost begins to dry, keeping the soil consistently moist throughout the growing season. Reduce watering in winter but never allow the soil to dry out completely — prayer plants do not tolerate drought. Always use filtered or rainwater to prevent the brown leaf tips caused by fluoride in tap water.
🌱 Fertilizing
Monthly spring to summer with diluted balanced liquid feed
Feed once a month from spring through summer with a balanced liquid houseplant fertiliser diluted to half strength. Reduce to every 6–8 weeks in autumn and stop entirely in winter when growth slows significantly. Avoid high-nitrogen feeds which promote lush leaf growth at the expense of patterning intensity.
✂️ Pruning
Remove yellowed leaves; trim leggy stems in spring
Remove any fully yellow or dead leaves at the base throughout the year. In spring, cut back any leggy or bare stems to just above a node to encourage fresh bushy growth from the base. Prayer plants spread rather than grow tall, so occasional reshaping keeps them compact and attractive.
🌿 Humidity
High humidity above 50% essential
Prayer plants require humidity above 50% and suffer in dry centrally heated rooms. Place on a pebble tray with water, group with other plants, or run a humidifier nearby. Mist the leaves in the morning — never in the evening, as wet foliage overnight encourages fungal disease. Brown crispy leaf edges are the primary sign of insufficient humidity.
Growing Tips
Use filtered or rainwater
Prayer plants are highly sensitive to fluoride and chlorine in tap water, which causes brown leaf tips and edges. Collect rainwater or let tap water sit uncovered overnight to allow chlorine to dissipate. Using filtered water consistently makes the most visible difference to leaf appearance.
Maintain high humidity
Maranta leuconeura is native to tropical Brazilian rainforests and needs humidity above 50%. Place the pot on a pebble tray filled with water (ensuring the pot base sits above the waterline), mist the leaves in the morning, or group with other plants. Avoid misting in the evening as wet leaves overnight can encourage fungal issues.
Keep away from cold draughts and direct sun
Prayer plants prefer bright indirect light and suffer in cold draughts from windows or air conditioning. Direct sun fades the distinctive leaf markings. A position a metre or two back from a bright east or west-facing window is ideal — enough light to maintain the vivid patterning without risk of scorch.
The night movement is normal and healthy
Leaves fold upward at night (nyctinasty) in response to light changes — this is normal and a sign of a healthy plant. If leaves stay folded during the day, the plant may be getting insufficient light or experiencing temperature stress.
Pests & Diseases
Pest Spider Mites
Identification: Fine webbing on stems and leaf undersides; pale yellow stippling across the leaf surface; leaves look dull and dusty.
- Increase humidity immediately — mites thrive in dry air and high humidity suppresses populations.
- Spray the whole plant with a forceful jet of water, then apply insecticidal soap weekly for 4 weeks.
- Apply an acaricide such as bifenazate; rotate actives on the second application to prevent resistance.
Pest Mealybug
Identification: White cottony masses in leaf axils and along the midrib; sticky honeydew on leaf surfaces.
- Dab each colony with a cotton bud soaked in 70% isopropyl alcohol.
- Follow with insecticidal soap spray weekly until no new colonies appear.
- Apply a systemic imidacloprid drench to the compost — sprays struggle to penetrate the waxy coating.
Pest Fungus Gnats
Identification: Tiny dark flies around the soil surface; larvae damage roots in consistently wet compost.
- Allow the top layer of compost to dry between waterings to break the larval cycle.
- Apply a biological nematode drench (Steinernema feltiae) to the compost.
- Use a pyrethrin-based soil drench as a last resort; nematodes are more effective and less disruptive.
Disease Root Rot Pythium spp. / Phytophthora spp.
Symptoms: Wilting leaves despite moist compost, yellowing lower foliage, black mushy roots when unpotted.
Treatment: Remove from pot, cut away all soft or blackened roots, dust cuts with powdered cinnamon or sulphur, and repot in fresh perlite-enriched compost in a clean pot with drainage holes.
Prevention: Never let the pot sit in standing water; always use a well-draining compost mix; reduce watering frequency in winter.
Disease Helminthosporium Leaf Spot Helminthosporium spp.
Symptoms: Small tan or brown spots with yellow halos on the leaf surface; spots enlarge in humid conditions and may coalesce.
Treatment: Remove and bin all affected leaves. Avoid overhead watering and misting directly onto foliage.
Prevention: Ensure good air circulation, water at the base of the plant, and avoid crowding plants together.
