A well-placed plant brings a room to life more than any decorative object. But plants do not forgive the wrong spot – and in Bulgarian homes the most common problems are too little light in north-facing and shaded flats and hot, dry air from central heating in winter. Here is how to choose plants that will live, not just survive.
An honest word about "air purification"
It is often said that plants clean the air at home. A 2019 Drexel University study (Cummings and Waring), reviewing decades of experiments, concluded that to match an ordinary building's air exchange you would need between 10 and 1,000 plants per square metre. In other words, plants are for mood and comfort; for clean air, open the windows. How to do that well is in our guide to healthy indoor air.
Start with orientation
- South – the most light; suited to succulents, cacti, citrus and pelargoniums. In summer, protect them from direct midday sun behind glass.
- East and west – gentle morning or afternoon sun; suits most foliage plants – ficus, monstera, palms, begonias.
- North – even but weak light; only shade-tolerant plants.
- The depth of the room matters: two or three metres from the window the light drops sharply, even if the room looks bright to the eye.
How orientation shapes the whole home and its lighting is covered in our guide to lighting your home.
Plants for a shady panel-block flat
Low floors, a north aspect, neighbouring blocks close by, or a deep loggia shading the room – that is the reality in many neighbourhoods. Plants that cope with such light include:
- ZZ plant (Zamioculcas) – almost indestructible and tolerant of infrequent watering.
- Snake plant (Sansevieria) – copes with shade and dry air.
- Pothos (Epipremnum) – grows fast and trails beautifully from a shelf.
- Cast-iron plant (Aspidistra) – the classic of older Bulgarian flats.
- Philodendron – more visible greenery, tolerates partial shade.
- Spider plant (Chlorophytum) – easy and quick to propagate.
No plant lives in total darkness – in a windowless hallway, only an LED grow light will help.
Heating and winter
Central heating is the biggest enemy of houseplants in Bulgarian homes:
- Do not place plants directly above a radiator or in front of an air-conditioner outlet – the leaf edges will dry out.
- Water less. In winter most plants grow slowly; overwatering and root rot kill more plants than drought. Water when the top layer of soil is dry.
- Humidity – group plants together and use a tray of pebbles and water. Plants add a little moisture to the air, but do not expect them to replace a humidifier.
- Cold glass – leaves touching the window can be damaged on cold nights. When airing, move sensitive plants out of the draught.
- More light – move plants closer to the window and wipe the dust off their leaves.
- Pests – dry air favours spider mites; check the undersides of leaves.
Plants that spend summer on the balcony and come inside for winter are the subject of our guide to a balcony garden.
Safety for cats and dogs
Some of the most popular houseplants are toxic to pets. According to information cited from the ASPCA:
- Dangerous: philodendron, pothos, peace lily, snake plant, dieffenbachia, aloe. They cause mouth irritation, drooling and vomiting.
- Lilies (Lilium and Hemerocallis) are especially dangerous for cats – the US Food and Drug Administration (FDA) warns that they can cause kidney failure.
- Considered safe: spider plant, Boston fern, calathea, peperomia, parlour palm, areca palm.
If you have a cat or dog, check every plant in the ASPCA database before buying, keep the dangerous ones out of reach, and if you suspect poisoning, contact a vet immediately.
Plants when you sell
From our photography and viewings: one or two healthy, large plants make a room look more alive and more expensive. Conversely, lots of small pots on the windowsills and sick plants with yellow leaves look like neglect.
- Choose one larger plant for the living room and one for the bedroom or kitchen.
- Remove dead leaves and wipe the pots.
- Do not block the windows – light is worth more than greenery.
- Use saucers under pots – buyers notice water stains on parquet.
In short
- Plants are for comfort, not air purification – open the windows.
- Choose by orientation and by the depth of the room.
- For shady rooms: ZZ plant, snake plant, pothos, cast-iron plant.
- Winter: away from the radiator, less water, more light.
- Cats and dogs: check every plant; never lilies with cats.
- When selling: a few large, healthy plants.
