Calathea, a very ornamental plant

Calathea houseplant
0

Evergreen, boldly patterned foliage that reaches 36 to 40 inches indoors: calathea is grown above all for the ornamental impact of its leaves. Native to South America, it asks for one thing above all — light shade well away from direct sun and radiators, with air kept moist — and it will stay lush.

Care, repotting, watering and exposure are some of the many small things to do that will make your calathea even more lush.

It makes our houses and apartments look lively with its elevated ornamental impact and unique foliage.

Planting and re-potting calathea

Upon purchasing, if the pot is too small, proceed to repot the plant so that it may grow adequately.

After that, every 2 or 3 years and preferably in spring, repot your calathea in a pot of a slightly larger size.

  • Calathea roots hate having too much water.
    Double-check that the pot has a hole in the bottom.
    Increase drainage with a layer of gravel or clay pebbles along the bottom of the pot, to make water flow through more easily.
  • Good soil mix is needed.
    Calathea, when it lives indoors, needs soil mix because that is the only source for the nutrients it needs.

Pruning, and caring for calathea

Remove wilted leaves regularly.

That will stimulate the sending of new shoots and will rejuvenate your plant.

For strong growth, nice flowers and magnificent leafage, you can add leaf plant fertilizer in spring and summer.

Calathea care through the year

What a calathea asks for changes with the seasons: generous watering and feeding while it is growing, much less once growth slows. This table sums up the routine season by season.

Calathea care through the year
Period Watering Feeding Other care
Early spring to late summer Keep the soil mix moist and check that water drains properly Leaf plant liquid fertiliser every 8 to 15 days Spray the leaves with calcium-free water
Early autumn to late winter Reduce watering and wait for the soil to be dry before watering again Stop adding liquid fertiliser Keep the plant away from radiators
All year round Regular but moderate, roughly every 2 or 3 days — Mist the leaves to recreate its natural moisture levels
Early spring, every 2 or 3 years Drainage layer of gravel or clay pebbles at the bottom Fresh soil mix supplies the nutrients Repot into a pot of a slightly larger size

Match the routine to the season and the foliage stays lush all year.

Where to place your calathea at home

Light shade suits it; direct sun is fatal

The best place to set up your calathea is near a window but not direct sunlight. Light shade is preferable, actually.

It is a plant that hence would feel right at home in rooms like bathrooms, laundry rooms, which are very moist and usually only have little light.

  • Indeed, it abhors excess luminosity.
  • Absolutely avoid setting it near heat sources such as radiators, because a lot of moisture is what this tropical plant needs most.
    Ideal temperatures are around 70°F (20°C).

Watering calathea

Regular but moderate watering is called for.

  • Watering every 2 or 3 days is recommended.
  • All year long and especially during summer, spray water on the leaves to recreate the moisture levels of its natural habitat.

In spring and summer
