Winter Care Tips for Indoor Plants

As winter approaches, caring for indoor plants becomes essential to ensure they thrive despite the cold. If you’ve been wondering about the best indoor plant fertiliser or ways to adjust care routines, this guide covers everything you need to keep your greenery healthy and vibrant.

At Food2Soil, we’re passionate about helping plant lovers nourish their green companions naturally. With the right approach — from using biofertilisers to balancing light and humidity — you can keep your plants flourishing through the colder months.

Watering Wisely

In winters most indoor plants grow at a rate which is lower and requires less water. Excessive watering also results in root rot, and one should ensure to check soil moisture before watering. Place your finger into the soil up to a fingernail length, when it feels dry add moisture.

Pro tip: Houses, where windows face the north or have good heating will need a bit more watering during winter. Troughs always vary depending on the requirements of your plant.

And don't forget to add Food2Soil as an indoor plant fertiliser occasionally to give the plants a gentle nutrient kick.

Using Biofertilisers for Winter Strength

Why biofertilisers matter in winter

Most plants naturally slow down in colder months, reducing their nutrient demands. Biofertilisers — derived from natural sources — release nutrients slowly, working in partnership with plant roots and microbes. This ensures a steady supply of nutrition over time without overwhelming dormant plants.

The result? Stronger resilience, steadier growth, and healthier leaves even when the world outside is frosty.

Boost Plant Immunity Naturally

Cold, dry conditions can weaken your plants’ defences. Using biofertilisers acts like a natural organic fertiliser, stimulating enzymes, antioxidants, and phytochemicals that strengthen immunity. This helps plants resist common winter stressors, pests, and diseases.

Keep Your Plants Clean

Plants “breathe” through their leaves, so dust-free foliage is essential. Wipe leaves with a damp cloth every two weeks or give them a gentle shower in the bath. On mild days, you can even let them enjoy natural rain outdoors — just avoid too much direct sun or cold exposure.

✨ Hot tip: After cleaning, apply a diluted organic fertiliser. This helps nutrients absorb efficiently through leaves and roots for a healthy mid-winter refresh.

Placement Near Light Sources

With shorter daylight hours, maximise sunlight by placing plants near sunny windows. Rotate pots to encourage even growth. For light-loving plants, artificial growing lights are a great complement. Suspend them a few inches above the leaves for the best effect.

Stable Temperatures = Happy Plants

Houseplants like 15–24°C temperatures. Move them away from cold drafts around doors or windows and from radiators or heaters. Consistency is ideal — stress plants with sudden changes.

Managing Humidity

Heating systems dry out the air, and plants miss humidity. Increase moisture by:

  • Grouping plants together

  • Placing pebble trays with water

  • Lightly misting (not fuzzy-leaved plants)

Dedicated plant parents might even invest in a humidifier for a “plant room.”
