Ellermann’s Guide to Healthy Houseplants

If you’re having trouble keeping your houseplants alive, The Style Sheet has enlisted expert help.

The impressive Diane Nittke — founder, owner and creative director of Ellermann Boutique & Event Design Atelier — shares her top tips for caring for indoor plants, as well as advice on which plants work best for Hong Kong’s climate.

The Three Cardinal Rules of Caring for Houseplants 

Consider optimal sunlight 

‘All plants require light to stay happy and healthy, so allowing natural sunlight into your space will give houseplants the nourishment they need. For the most part, however, indirect light is best for growing plants in your home. Most varieties of houseplants require indirect light, which is why they’re optimal for growing indoors,’ Diane explains. ‘If you see yellow or dropping leaves or longer spindly stems, this may indicate your plant wants more light. A change of position in the room, a different room, or adding a lamp nearby are all good ideas. Noticing pale leaves or crispy browning areas? This may mean your plant needs a step back from too much light, or from too much direct light.’

Monitor watering and soil moisture

‘Not all plants need the same amount of water, so try to make a habit of checking on your houseplants at least every week to see if they need a drink. The best way to tell if your plants need water is to stick your finger four or five centimetres into the soil —  if it feels dry, water the plants thoroughly,’ Diane says. ‘If you detect dampness, check back again in a few days. The time of year can make a difference to watering frequency, too. Many houseplants grow more during spring and summer, but not as much in autumn and winter. If you notice less growth than usual, water less frequently until the plant starts growing when the weather gets warmer.’

Don’t forget to clean

‘It's important to clean plant leaves regularly, as a layer of dust on a houseplant’s leaves will block sunlight and reduce the plant’s ability to photosynthesise. The best way to tell if a plant needs cleaning is to rub your fingers on the leaves. If you can feel or see more dust than you can blow off the leaves, it’s time to clean; simply wipe the leaves with a damp cloth. This is also an opportunity to check for pests — pay attention to stems, stalks and soil and check every week.’
