Keep your indoor plants cozy this Winter.

As winter approaches in Johannesburg, South Africa, many plant enthusiasts find themselves worried about the health of their indoor plants. While South African winters are milder compared to other regions, indoor plants still require special care to thrive during the colder months. At Garden Shop, we are dedicated to helping you keep your indoor garden flourishing all year round. Here are our top tips for indoor plant care during the South African winter.

Understanding Johannesburg's Winter Climate

Johannesburg experiences a relatively mild winter with average temperatures ranging from 4°C to 16°C. Despite the mildness, indoor plants can still face challenges due to reduced daylight hours, lower temperatures, and dry indoor air from heating systems. These factors can affect plant growth and health, making it essential to adjust your care routine accordingly.

1. Optimise Light Exposure

Winter days are shorter, and the sunlight is less intense. To ensure your plants receive enough light:

• Move Plants Closer to Windows: Place your indoor plants near north or east-facing windows where they can get the most sunlight. Avoid south-facing windows as the direct sun can be too harsh.
• Use Grow Lights: Supplement natural light with grow lights, especially for plants that require more light. LED grow lights are energy-efficient and effective in providing the necessary light spectrum for plant growth.

2. Adjust Watering Routine

Overwatering is a common mistake during winter. With reduced evaporation, plants require less water:

• Check Soil Moisture: Allow the top inch of soil to dry out before watering. Stick your finger into the soil to check for moisture.
• Reduce Watering Frequency: Water less frequently but ensure thorough watering when you do. Empty any excess water from saucers to prevent root rot.
• Use Lukewarm Water: Cold water can shock the roots. Use water at room temperature to keep your plants comfortable.

3. Maintain Humidity Levels

Indoor heating can create dry air, which is not ideal for most indoor plants:

• Group Plants Together: Placing plants close to each other can create a micro-humidity environment.
• Use Humidifiers: A humidifier can help maintain optimal humidity levels, especially for tropical plants.
• Mist Plants: Lightly mist your plants with water using a spray bottle, but avoid overdoing it to prevent fungal issues.

4. Regulate Temperature

Keep your indoor environment stable to avoid stressing your plants:

• Avoid Drafts: Keep plants away from cold drafts from windows and doors, as well as hot air from heating vents.
• Maintain Consistent Temperatures: Aim to keep the room temperature between 18°C to 24°C (64°F to 75°F) during the day and not lower than 10°C (50°F) at night.

5. Prune and Clean

Winter is an excellent time to tidy up your plants:

• Remove Dead Leaves: Trim away any yellowing or dead leaves to encourage new growth and prevent pests.
• Clean Dust from Leaves: Dust can block light absorption. Gently wipe leaves with a damp cloth to keep them clean.

6. Monitor for Pests

Indoor plants can still be susceptible to pests during winter:

• Check Regularly: Inspect your plants regularly for signs of pests such as spider mites, aphids, and mealybugs.
• Use Natural Remedies: If you find pests, use natural remedies like neem oil or insecticidal soap to treat the infestation.

7. Fertilise Sparingly

Plants grow slower in winter, so they require fewer nutrients:

• Reduce Fertiliser Use: Cut back on fertilizing to once a month or even less, depending on the plant type.
• Use Balanced Fertilisers: Choose a balanced, water-soluble fertilizer to provide essential nutrients without overfeeding.
