1. WRAP UP PLANTS IN CONTAINERS TO KEEP THEM SNUG
Container plants are vulnerable when frost strikes as they are more likely to suffer from their roots freezing than plants in the ground are. The soil in pots will be colder, and it's important not to cover it at the top too as it needs to 'breathe'. So what should you use to cover plants? To prevent your plants freezing, use bubble wrap (like this from Amazon), straw, sacking, newspaper or old towels to add a layer of insulation.
2. MOVE PLANTS TO A SHELTERED SPOT
The mantra 'right plant, right place' is relevant when considering how to protect plants from frost. Slightly tender plants grown against a south-facing wall will get extra warmth and winter protection from frost. It's also a good idea to leave the previous season's growth on tender plants until spring as this adds another layer of frost protection in winter.
3. GET A MINI GREENHOUSE OR COLD FRAME
Although you might not have space for a full-size greenhouse it's easy to squeeze in a mini one. There are some small stylish mini greenhouses like this one from Amazon to choose from. Even the smallest ones are invaluable if you're looking for ideas on how to protect plants from frost.
4. USE FROST CLOTHS AND CLOCHES IN THE VEGETABLE GARDEN
In terms of vegetable crops, there are plenty to choose from that actually benefit from a dose of frost and taste better afterwards. Frost tolerant vegetables include leafy greens like spinach, chard, kale and cabbage. A layer of horticultural fleece like this from Amazon is effective at keeping some of the frost off less hardy crops in a vegetable garden. Keep it raised above the plants with hoops to encourage air circulation, and peg the sides down so it doesn't blow away if it's windy.
5. LAYER UP SOME MULCH AROUND PLANTS
Most plants benefit from a layer of mulch over their roots for added protection from winter chills. You can use a variety of materials like garden compost, wood chippings or leaf mold for mulching and, as an added bonus, mulch boosts the nutrient content of soil as it is pulled down into the ground by earthworms.
6. FIND OUT WHEN IT’S SAFE TO PLANT OUTSIDE AGAIN
Get to know your local climate and don't get caught out, as Mother Nature often likes to throw out a curveball when it comes to late spring frosts. You’ve probably heard the term 'last frost date' with reference to when you can start planting outside in spring. Do your homework and find out the date of last spring frosts in your local area in recent years. You can also find out frost dates according to your zipcode, courtesy of the National Gardening Association.
