Protecting Plants from Frost in Johannesburg: A Guide to Frost Cover
Johannesburg is known for its subtropical highland climate and mild winters. However, being at an elevation of 1753 metres above sea level means the city can get frosty in winter which can damage or kill sensitive plants. Protecting your plants with frost covers from Indigo Garden Nursery is essential.
Understanding Johannesburg’s Winter Climate
During Johannesburg’s winter (June to August) daytime temperatures range from 16°C to 19°C. Night time temperatures can drop below freezing making frost likely and while frost in Johannesburg isn’t as severe as in other places, it can still harm gardens.
What is Frost and How Does it Affect Plants?
Frost forms when temperatures drop to freezing, causing water vapor to condense into ice crystals on surfaces, including plants. This can lead to:
- Cellular Damage: Ice crystals within plant cells can cause them to burst, leading to tissue damage.
- Dehydration: Frost extracts moisture from plant leaves and stems, causing dehydration and stress.
- Growth Delay: Frost can delay blooming and fruiting cycles, even if the plant survives.
Benefits of Using Frost Covers
Frost covers, also known as frost cloths or plant blankets, offer several benefits:
- Insulation: Traps ground heat and maintains a warmer microclimate around plants.
- Protection from Wind: Shields plants from winter winds that exacerbate frost effects.
- Breathability: Allows moisture and heat to escape, preventing mold and rot.
- Versatility: Suitable for various plants, from delicate annuals to larger shrubs and trees.
Tips for Using Frost Covers Effectively
- Timing: Frost cover can be left on plants till Spring. No need to remove the frost cover at all till the weather warms..
- Secure Fit: Anchor covers securely with stakes, rocks, or other weights.
- Size and Coverage: Ensure covers drape completely over plants, reaching the ground. Use multiple covers for larger plants.
