Monstera and Philodendron Care Guide: How to Grow These Tropical Plants in Ireland
Monstera deliciosa and Philodendron varieties thrive in Irish homes with bright indirect light, temperatures of 18–27°C, and watering every 1–2 weeks — conditions easily achieved in most modern Irish living rooms and kitchens. Both genera originate from the tropical rainforests of Central and South America, and their adaptability to indoor environments makes them two of the most rewarding houseplants you can grow in Ireland. This complete care guide covers light, water, humidity, soil, propagation, and troubleshooting for Monstera deliciosa, Philodendron hederaceum (Heartleaf), Philodendron Brasil, and Philodendron scandens 'Micans', with plants available from €12.95 delivered anywhere in Ireland.
Monstera deliciosa gets its name from the Latin words for "monstrous" (referring to its enormous leaves) and "delicious" (for its edible fruit, which tastes like a combination of pineapple and banana). In the wild, Monstera deliciosa vines can climb trees to 20 metres — indoors in Irish homes, expect a more modest but still impressive 1–2 metres of growth over several years.
How Much Light Do Monstera and Philodendron Need?
Both Monstera deliciosa and Philodendron species need bright, indirect light for at least 4–6 hours per day to grow vigorously and produce their best foliage. In Irish homes, an east- or west-facing window is ideal — the gentle morning or afternoon sun filtered through a net curtain provides exactly the right intensity. South-facing windows can work well in winter when the sun is low, but in summer you may need to move the plant back from the glass to avoid leaf scorch. North-facing rooms are acceptable for Philodendron scandens and Philodendron hederaceum, which tolerate lower light better than Monstera, but growth will be slower and Monstera leaves will lose their characteristic fenestrations (holes) over time.
Avoid positioning either plant directly beside a radiator or in a draught from a door or window — both cause leaf browning and stress. If your Irish home has limited natural light in winter, a full-spectrum LED grow light on a timer for 12–14 hours per day will keep both species growing healthily through the darker months from November to February.

How Do You Water a Monstera Plant?
Water your Monstera deliciosa when the top 5cm of compost feels dry to the touch — typically every 1–2 weeks depending on the season and your home's temperature. The single most common mistake with Monstera in Irish homes is overwatering: our cooler, damper climate means soil stays moist longer than in warmer countries, so a schedule that works in Mediterranean climates will cause root rot here. Always check the soil before watering rather than following a fixed calendar. Use your finger or a wooden skewer — if it comes out with damp compost clinging to it, wait a few more days.
For Philodendron species — including Philodendron hederaceum (Heartleaf), Philodendron Brasil, and Philodendron scandens — the same rule applies: water when the top 3–5cm of compost dries out. Philodendrons are slightly more tolerant of inconsistent watering than Monstera, but they too will develop yellow leaves and root rot if consistently overwatered. In Irish winter months (November to February), reduce watering frequency to once every 2–3 weeks as growth slows and evaporation rates drop.

What Humidity Do Monstera and Philodendron Need?
Monstera deliciosa and Philodendron species prefer humidity levels of 50–70% — higher than the 40–50% typical of most Irish living rooms, but well within the range achievable without specialist equipment. Irish bathrooms naturally reach 70–80% humidity during and after showers, making them excellent spots for these tropical plants provided a window or good ventilation ensures some light and air circulation. In Irish living rooms, central heating during winter months can drop humidity as low as 30–35%, which causes brown leaf edges and tip browning — the most reliable sign that your plant needs more moisture in the air.
The simplest way to boost humidity is a pebble tray: fill a shallow tray with pebbles, add water to just below the surface of the pebbles, and sit your pot on top. As the water evaporates, it creates a localised humid microclimate around your plant. Alternatively, grouping tropical plants together increases ambient humidity through collective transpiration. Regular misting directly onto leaves can help in the short term but is less effective than a pebble tray or room humidifier.
An east-facing kitchen window is arguably the best spot in a typical Irish home for both Monstera and Philodendron. The kitchen naturally has higher humidity from cooking, the morning light is gentle and indirect, temperatures are stable (typically 18–22°C year-round), and proximity to the sink makes watering convenient. Avoid placing these plants near the back door or hallways where cold draughts from Irish winters can cause leaf drop and browning.
What Soil Does Monstera deliciosa Need?
Monstera deliciosa requires a well-draining, chunky substrate that holds some moisture but allows excess water to drain freely and air to reach the roots. In its natural habitat, Monstera grows in loose, aerated forest floor soil rich in organic matter — compacted, dense compost will suffocate its roots and cause the root rot that most commonly kills indoor Monstera plants. For Philodendron species, the same principle applies: they are epiphytes by nature (meaning they can grow on other plants), so their roots expect aerated, fast-draining conditions.
An ideal homemade mix for both plants combines three parts standard houseplant compost, two parts perlite (the small white volcanic granules that improve drainage and aeration), and one part orchid bark or coarse coco coir. This mixture drains quickly, doesn't compact over time, and provides the organic richness these tropical species need. Ready-made aroid mixes are increasingly available in Irish garden centres and online and are an excellent choice for beginners.
What Temperature Do These Plants Prefer?
Monstera deliciosa and Philodendron species thrive at temperatures between 18–27°C — a range that aligns perfectly with modern Irish homes, which typically maintain 18–22°C year-round with central heating. Both plants will survive brief periods down to 12°C but will suffer significant stress, yellowing, and leaf drop if temperatures fall below 10°C. This makes them unsuitable for unheated conservatories, garages, or outbuildings during Irish winters, where temperatures can regularly drop to 0–5°C from November through February.
Keep Monstera and Philodendron away from cold single-pane windows in winter — the glass surface can become very cold on Irish frost nights, and leaves touching the glass will sustain cold damage. Similarly, avoid positioning these plants directly in the stream of air from air conditioning units, which chill and dry the foliage simultaneously. The stable warmth of a central-heated Irish sitting room or kitchen, maintained at 19–21°C, is close to ideal for year-round tropical plant growth.

How Do You Propagate Monstera and Philodendron?
Both Monstera deliciosa and Philodendron species propagate readily from stem cuttings — one of the most satisfying aspects of keeping these plants. For Monstera, locate a healthy stem with at least one node (the brown, slightly raised joint from which leaves and aerial roots emerge) and ideally an existing aerial root. Using clean, sharp scissors or a knife, cut 2–3cm below the node. For Philodendron Brasil, Heartleaf Philodendron (Philodendron hederaceum), and Micans, take a cutting with 2–3 leaves, cutting just below a node.
Place the cutting in a clean glass of water in a bright, warm spot — an east-facing Irish windowsill in spring is ideal. Change the water every 5–7 days to keep it fresh and prevent bacterial build-up. Monstera cuttings typically produce visible roots within 3–6 weeks; Philodendron cuttings often root within 2–4 weeks. Once roots are 3–5cm long, pot into a well-draining aroid mix and keep the compost consistently moist for the first 2–3 weeks as the plant adjusts. Spring (March to May) is the optimum time to propagate in Ireland, when increasing day length and temperatures encourage rapid root development.
Why Is My Monstera or Philodendron Turning Yellow?
Yellow leaves are the most common complaint from Monstera and Philodendron owners in Ireland, and in the vast majority of cases the cause is overwatering. Irish homes and climates do not allow soil to dry as quickly as warmer countries, so many Irish plant owners water on a fixed weekly schedule that is simply too frequent for our conditions. Before reaching for the watering can, always check the soil first. Below is a comprehensive troubleshooting guide to the most common problems with Monstera and Philodendron plants in Irish homes.
| Symptom | Most Likely Cause | Fix |
|---|---|---|
| Yellow leaves (widespread) | Overwatering / root rot | Reduce watering frequency, check drainage, allow soil to dry fully between waterings |
| Yellow lower leaves (occasional) | Normal ageing | No action needed — remove yellow leaf cleanly at the stem |
| Brown leaf edges / crispy tips | Low humidity or tap water minerals | Use filtered or rainwater; add a pebble tray or humidifier |
| Brown patches on leaves | Sunburn from direct light | Move away from south-facing glass; use a net curtain for filtering |
| No new leaves / very slow growth | Low light or root-bound | Move to brighter spot or repot into a pot one size larger |
| Drooping / wilting leaves | Underwatering or severe root rot | Check soil: if bone dry, water thoroughly; if soggy, unpot and inspect roots |
| Small leaves without fenestrations | Insufficient light or young plant | Move closer to a bright window; mature plants fenestrate at 60cm+ |
| Leggy / stretched growth | Low light — plant reaching for light source | Move to a brighter location; rotate regularly for even growth |
| Black stems near soil | Root rot from overwatering | Unpot immediately, trim rotten roots, repot in fresh dry mix, reduce watering |
| White powdery coating on leaves | Powdery mildew (rare indoors) | Improve air circulation, reduce humidity slightly, treat with diluted neem oil |
