Brrr... But Blooming! How to Care for Plants in the Cold

Helping Plants Thrive Through Autumn & Winter

🍁 1. Adjust Your Watering Routine

Plants need less water in the colder months. Overwatering is a common mistake during autumn and winter. Outdoor plants benefit from natural rainfall, so only water when the soil feels dry a few centimetres below the surface. For indoor plants, wait until the top inch of soil is dry before watering, and ensure pots have good drainage to avoid soggy roots.

🧊 2. Protect Plants from Frost

Frost can damage tender plants, so it’s essential to act early. Use fleece, cloches, or plant covers to shield delicate species overnight. Move pots to sheltered areas, such as close to house walls or inside greenhouses. Even a simple layer of mulch can help insulate roots in beds and containers.

🌤 3. Maximise Light for Indoor Plants

Shorter days mean less natural light, which can affect growth. Move houseplants closer to windows, ideally south-facing, to make the most of available sunlight. Clean leaves gently to remove dust that can block light, and rotate pots regularly so plants grow evenly.

🌿 4. Tidy and Prune Wisely

Autumn is the perfect time to clear away fallen leaves and dead growth. Pruning helps prevent disease and encourages healthy regrowth in spring. Cut back herbaceous perennials and remove any rotting foliage to reduce the risk of pests.

🪴 5. Bring Tender Plants Indoors

Many Mediterranean or tropical plants, such as geraniums, citrus trees, and succulents, won’t tolerate frost. Move them into a greenhouse, conservatory, or bright indoor space before the first frost hits. Keep them away from direct heat sources like radiators. 

🌡 6. Maintain a Steady Environment

Sudden temperature changes can shock plants. For indoor varieties, keep them away from draughts, radiators, or frequently opened doors. A cool but stable room temperature is ideal, especially for overwintering tender plants. 

🌱 7. Reduce Feeding

During autumn and winter, most plants enter a slower growth phase. Stop or reduce fertiliser use to avoid encouraging soft new growth that’s vulnerable to cold. You can resume regular feeding in spring.

With a few thoughtful adjustments, your plants can thrive through the colder months. By protecting against frost, managing light and water, and giving them a little extra attention, you’ll set the stage for a healthy, vibrant spring garden.
