How to Combine Houseplants in One Pot: Choosing and Planting

Several houseplants in one wide pot look like a miniature garden: the arrangement is more striking than single pots, takes up less windowsill space and makes a lovely gift. But to avoid ending up with just one living plant a month later, you need to choose the neighbours wisely. Here's which plants grow well together, how to design an arrangement with the "thriller, filler, spiller" rule, how to plant and care for it — plus ready-made combinations.

The key rule: the same conditions

Plants in one pot share the same light, the same watering and the same soil, so only plants with similar needs can be combined. A fern and a cactus look striking together, but the fern needs moist soil and the cactus dry, so one of them is bound to die.

It helps to think in groups:

• Shade-loving "tropicals": calatheas, marantas, fittonias, aglaonemas, ferns, peperomias, ivy and pothos. They like bright indirect light, humid air and consistently slightly moist soil.
• Succulents and cacti: echeverias, haworthias, crassulas, sedums, lithops and cacti. They need bright light, gritty soil and infrequent watering.
• Sun-loving colourful plants: croton (codiaeum), coleus, hypoestes and iresine. They need plenty of light for bright colours and regular watering.

Avoid mixing plants from different groups — even if each is easy-going on its own.

How to make it look good

Florists and garden designers use a simple three-role scheme:

• Thriller — a tall, upright focal plant, placed in the centre of a round arrangement or at the back if it's seen from one side.
• Filler — mid-height plants that fill the space and add volume.
• Spiller — trailing plants that spill over the rim and soften the arrangement.

Add contrast: large leaves next to small ones, glossy next to velvety, plain next to variegated. One or two flowering plants make a great accent, but keep the rest calm.

How to plant it: step by step

1. Choose a container that is wide, not too deep and always has a drainage hole. A basket or decorative cachepot works if you put a plastic pot with holes inside.
2. Add drainage — 2–3 cm of clay pebbles at the bottom so water doesn't pool around the roots.
3. Pick the right soil for the group: all-purpose compost with perlite for tropicals, gritty cactus mix for succulents.
4. Arrange the plants in their pots first — it's easy to judge the layout and swap them around.
5. Plant from the centre outwards: thriller first, then fillers and finally spillers at the edge. Leave 3–5 cm between plants to grow.
6. Fill in with soil, firm gently and water. Wait 5–7 days before watering succulents so damaged roots can dry.

How to care for it

• Water for the most sensitive plant and check the soil with your finger rather than following a schedule.
• Turn the pot every week or two so the plants grow evenly.
• Feed sparingly in spring and summer — over-feeding is riskier in a shared pot. Gentle options are covered in our article on natural fertilisers.
• Pinch and trim vigorous neighbours so they don't smother slower plants.
• Divide every 1–2 years as plants outgrow the pot — an indoor arrangement isn't forever, and that's fine.

Ready-made combinations

• "Rainforest" for partial shade: aglaonema in the centre, calathea and fittonia at the sides, pothos around the edge.
• Succulent garden for a sunny sill: a jade plant (crassula) in the centre, echeverias and haworthias around it, sedum at the edge.
• Bright accent: croton, pink-spotted hypoestes, silver pilea and tradescantia.
• Flowering gift: two or three African violets in different shades with peperomia and fittonia — a gentle gift for a bright sill out of direct sun.

FAQ

Can I plant cacti with other houseplants?

Only with other succulents: most leafy houseplants need moister soil.

How many plants fit in one pot?

A 25–30 cm pot usually holds 3–5 plants: one thriller, 2–3 fillers and 1–2 spillers.

Do I need drainage if the pot has no hole?

Better to put a pot with holes inside: even a thick drainage layer won't prevent waterlogging in a sealed container.
