Water your prayer plant every 7–10 days in summer when the top 2 inches of soil are dry. In winter, stretch that to every 10–14 days. Always use filtered or rainwater if your tap water is hard — prayer plants are more sensitive to mineral buildup than most houseplants.
That’s the short version. Here is the detail behind it — because watering is where most Maranta leuconeura problems begin.
Quick Reference
- Watering frequency: Every 7-10 days (summer), 10-14 days (winter)
- Soil check method: “Top 2 inches” rule — water when this layer is dry
- Water type: Filtered, rainwater, or tap water left to sit 24 hours
- Best soil mix: 60% potting mix + 30% perlite + 10% orchid bark
- Pot type: Terracotta or any pot WITH drainage holes — never waterproof
- Biggest mistake: Watering on a schedule instead of checking soil first
How Often to Water a Prayer Plant
Water when the top 2 inches (5 cm) of soil are dry — not on a fixed schedule. This rule holds through all seasons and all apartment conditions.
Why does this matter? Because “every 7 days” might be right for summer but too frequent for winter when light is low and the plant’s metabolism slows. A prayer plant sitting in soggy soil for 2 weeks in January is a recipe for root rot.
The simplest check: press your finger 2 inches into the soil. If it feels damp, wait. If it feels dry and crumbly, water thoroughly until it drains from the bottom.
Joakim uses a moisture meter (stuck in at the pot’s halfway point) after we lost one plant to root rot despite what felt like “correct” watering. The meter revealed the centre of the pot was staying wet far longer than the surface suggested.
If you’ve had an overwatering issue before, a moisture meter removes the guesswork entirely:

Insert it 2 inches deep before every watering. Tells you exactly what is happening at the root zone where rot actually starts.
Water Quality: Why Tap Water Is Often the Problem
We learned this the hard way. Brown tips appeared despite consistent watering and high humidity. The issue was our Aarhus tap water — hard water with high mineral content. After switching to filtered water, no new brown tips appeared within 2 months.
Prayer plants are sensitive to:
- Chlorine and chloramines — let tap water sit in an open container overnight to allow chlorine to dissipate (this works for chlorine but NOT chloramines).
- Fluoride — accumulates in soil over time, causing leaf tip burn. Flush the soil thoroughly every 2-3 months by watering heavily until it pours from drainage holes.
- Hard water minerals (calcium and magnesium) — build up as white residue on soil surface and leaf edges. Filtered or rainwater avoids this entirely.
The easiest solution: collect rainwater if you have outdoor space, or run tap water through a standard filter pitcher. Distilled water works but strips everything — add a tiny amount of balanced liquid fertiliser when using distilled water exclusively.
The Best Soil Mix for Prayer Plants
Prayer plants come from the Brazilian forest floor — a substrate that’s rich in organic matter but drains quickly and never sits waterlogged. Standard bagged potting mix is too dense and retains too much moisture on its own.
For this part of the guide, a researched product option that fits the job is:
Selected because this section is specifically about potting mix use. Check Amazon for current price and availability.
Our mix (what we actually use):
- 60% good-quality peat-free potting mix
- 30% perlite (improves drainage and aeration)
- 10% orchid bark (adds chunky structure, prevents compaction)
This mix holds moisture well enough to keep prayer plants happy, but drains fast enough to prevent waterlogging. You can pre-purchase a similar mix labelled “aroid mix” from specialist retailers — the composition is comparable.
If you prefer a pre-made mix that works well for prayer plants with minimal amendment:
A powerhouse blend with earthworm castings and bat guano. Perfect for hungry tropicals that want to grow big.
Best Pots for Prayer Plants
The most important feature: drainage holes. Non-negotiable. Prayer plants sitting in water at the bottom of a decorative pot (with no drainage) are on a slow path to root rot.
Terracotta pots are the best choice for prayer plants. They’re porous, which means excess moisture can evaporate through the sides, reducing overwatering risk. The tradeoff: terracotta dries out faster, so you’ll need to water more frequently in summer.
Plastic or glazed ceramic pots retain moisture longer — good for forgetful waterers, but they leave less margin for error if you tend to overwater.
Pot size: Use a pot only 1–2 inches (2.5–5 cm) larger than the root ball. Oversized pots hold too much soil, which stays wet for too long. Prayer plants prefer being slightly snug rather than having excess space.

Prayer Plant Watering & Soil FAQ
How often should I water my prayer plant?
Water when the top 2 inches (5 cm) of soil are dry — typically every 7-10 days in summer and 10-14 days in winter. Never water on a fixed schedule; always check the soil first.
Can I use tap water for my prayer plant?
If your tap water is soft and low in minerals, yes. If it’s hard or has high fluoride/chloramine content, switch to filtered water, rainwater, or tap water left to sit overnight. Brown leaf tips are the main symptom of tap water mineral buildup.
What is the best soil for prayer plants?
A well-draining mix of 60% potting soil, 30% perlite, and 10% orchid bark works well. Standard potting mix alone is too moisture-retentive and increases root rot risk.
Should prayer plants be in terracotta or plastic pots?
Terracotta is better because it’s porous and allows excess moisture to evaporate, reducing overwatering risk. Any pot must have drainage holes — prayer plants will rot in pots without drainage.
How do I know if I’m overwatering my prayer plant?
Signs of overwatering include yellowing leaves (especially lower leaves), soggy soil that stays wet for more than 2 weeks, and musty smell from the pot. The definitive test is removing the plant from the pot — healthy roots are white and firm; rotted roots are brown/black and mushy.
