Frost Protection Basics

Here's the short, honest answer, and one tip most people miss.

Frost-Sensitive Plants

Here's the thing: not every leaf shivers the same. The ultra-tender ones, think papaya, banana, basil, even young mango, can black out in a single night. A step up are lemons, chillies and tomato seedlings, they need a blanket but survive better. Peas, spinach and the cabbage family? They shrug it off.

Cover Right Way

And this is where it gets interesting. First, pop three or four sticks a little taller than the plant to make a simple frame. Then drape an old cotton sheet, a jute sack or frost cloth over it, letting the edges rest on the soil or pot rim. Crucially, don’t pull it tight, warm air from the ground needs a little breathing room.

Frost threshold

Now, the part most people miss: frost usually shows up when the night temperature dips to about two degrees Celsius or lower. That’s the sweet spot where the ground freezes but the sun can still melt a bit in the morning.

Plastic Mistake

The plastic mistake: where cold actually gets in. Thin plastic acts like a cold conduit, freezing any leaf it touches. If you must use plastic, first layer a cloth or newspaper, or set the plastic on a frame with at least a hand-width gap all around. That way the cold stays out of the leaves.

Water Before Frost

Should I water plants before frost? Yes, if the soil is dry. Moist soil holds the day's warmth and gives it back at night, protecting roots. Aim to water in the morning or early afternoon, keeping leaves dry. And no, don’t keep the soil soggy all winter, wet roots rot faster than they freeze.

Warmest Pot Spots

Now, the part most people miss: where to put those pots for extra warmth. A south-facing wall absorbs daytime heat and releases it after dark. An overhang or roof edge gives a little shelter from open sky. And if you cluster pots together, they share that heat and block the wind.

Fog & Fungus Tips

Does fog harm plants? Not directly, but those damp, smoggy weeks can invite fungus. Space your pots so air can move, water only in the morning and aim at the soil, and give sturdy leaves a gentle rinse on a sunny morning so they dry by afternoon. Remove any spotted or mouldy leaves and toss them, not into compost.

Leave burnt leaves

What surprised me is that those brown, crisp leaves you see after a frost night are actually protecting the buds below. So resist the urge to prune them away now, just let them stay until spring, and the new growth will push through.
