A Beginner's Guide to Growing Monstera at Home

Last updated: 20 May 2026

Monstera deliciosa — commonly called the Swiss cheese plant — is among the most widely sold houseplants in Poland. Its large, lobed leaves and adaptability to indoor conditions have made it a fixture in Polish homes, offices, and co-working spaces across Warsaw, Kraków, Wrocław, and Gdańsk. Despite its dramatic appearance, the plant has straightforward requirements that make it manageable for first-time growers.

Light placement in Polish apartments

In its natural habitat, monstera grows beneath a forest canopy, receiving filtered sunlight rather than direct rays. This translates well to indoor Polish conditions. A position near a south-facing or west-facing window — but set back two to three metres from the glass — provides the bright indirect light that encourages the characteristic fenestration (splits and holes) in the leaves.

Monstera grown in north-facing rooms or corridors with minimal natural light will survive but will produce smaller, unperforated leaves. If fenestration is important to you, placing the plant near the brightest available window will make a noticeable difference over time.

During Poland's winter months (November through February), the number of daylight hours drops significantly. Even south-facing windows may provide only four to five hours of usable light per day. Moving the plant to within 50–80 cm of the window during this period helps maintain growth. Some growers supplement with a simple LED grow lamp positioned above the plant for several hours each day, though this is not strictly necessary for the plant's survival.

Watering in the Polish climate

The most reliable approach is to water when the top 3–4 cm of soil has dried out. In summer, this typically occurs every seven to ten days. In winter, when growth slows and soil dries more slowly in cooler rooms, watering frequency often extends to every 14–21 days.

Polish tap water is generally suitable for monstera. If the local supply has high chlorine content (detectable by smell), leaving the water in an open container for 24 hours before use allows chlorine to dissipate. Some growers in cities with harder water, such as Warsaw, use filtered water to prevent white mineral deposits on the soil surface, though this is a cosmetic issue rather than a plant health concern.

Signs of overwatering vs. underwatering

Yellow leaves with soft, mushy petioles typically indicate overwatering. The problem is often compounded by nursery-supplied peat soil, which holds moisture for longer than the plant requires. Brown, crispy leaf tips are more commonly associated with low humidity or underwatering. Both can occur simultaneously in heated Polish flats during winter.

Soil and potting

Most monstera plants sold in Polish garden centres and supermarkets (such as Leroy Merlin or Castorama, which carry houseplants seasonally) arrive in standard peat-based potting mix. This soil is adequate for transport and initial display but becomes compacted and waterlogged over time.

For longer-term growing, a mix of approximately 60% standard houseplant soil, 20% perlite, and 20% orchid bark improves drainage and aeration around the roots. This combination is available at most Polish plant shops and some online retailers. Repotting into a terracotta or plastic container with drainage holes is preferable to decorative pots without drainage, which trap water at the base of the roots.

Managing humidity in heated flats

Central heating in Polish apartments reduces indoor humidity considerably during winter. While monstera handles humidity levels between 30% and 40% without visible stress in most cases, it performs better at 50–60%. A simple room humidifier in the same space as the plant is the most effective solution. Grouping multiple plants together increases the local humidity slightly through transpiration. Regular misting provides only brief, superficial humidity and is less effective than a humidifier for improving ambient moisture.

Supporting growth

Monstera develops aerial roots that, in nature, allow it to climb trees. Indoor plants benefit from a moss pole or coir totem that these roots can attach to. Plants supported in this way tend to produce larger leaves with more pronounced fenestration than those left to trail horizontally. Moss poles are widely available from Polish online plant retailers and some specialist houseplant shops in larger cities.

Common problems

• Root rot: The most serious risk. Caused by overwatering combined with poorly draining soil. Affected plants show yellow leaves, soft stems, and a musty odour from the pot. Treatment involves removing the plant from its pot, cutting away affected roots with sterilised scissors, and repotting into dry, well-draining soil.
• Spider mites: Common in dry, heated Polish flats from October to April. Fine webbing on the undersides of leaves is the primary indicator. Increasing humidity and wiping leaves with a damp cloth helps control small infestations. Neem oil solution or insecticidal soap, available at Polish garden shops, addresses more severe cases.
• Brown leaf edges: Usually indicates low humidity, irregular watering, or mineral build-up in the soil from tap water. Flushing the soil with clean water every few months reduces salt accumulation.
