Gardening tips: four ways to beat the freeze

From plant protection to returning to microgreens, follow our tips to avoid herbaceous harm from sub-zero Easter temperatures

1. Seed potatoes are traditionally planted on Good Friday, but many gardeners have delayed. If the ground is frozen, try planting in containers instead. Two or three early tubers such as Rocket or Red Duke of York placed in a large builder's bucket or plastic bin (drill holes in the bottom for drainage) will produce a good crop of spuds, and they're less vulnerable to slugs, too. Cover the container with horticultural fleece or place in a frost-free shed until the weather warms. If your soil isn't frozen, do plant outside but protect the rows with several layers of fleece.

2. Throw fleece over newly emerged shoots of herbaceous perennials in exposed spots in the garden to shield them from freezing winds. Fleece will also protect open flowers and buds of delicate fruit trees such as apricots and cherries. Mulches can help to preserve moisture in the soil and suppress weeds, but if applied when the soil is frozen they will simply lock in the cold for longer, so wait for a thaw. If you must get on with something in the garden, prune gooseberries and autumn-fruiting raspberries and tie in blackberry canes.

3. Most vegetable seeds need a consistent soil temperature of 6-8C before they can be sown direct: peg down black plastic sheeting over bare soil to warm it ready for sowing and planting. In the meantime, sow seeds of parsley, cabbages and lettuces in plastic module trays and place them on a warm, sunny windowsill, with a clear plastic bag or clingfilm over the trays to trap in heat. Once the weather warms and you can see roots poking through the drainage holes, harden seedlings off by gradually exposing them to conditions outside. Plant out once you're comfortable working without a coat.

4. Microgreens are the ultimate quick-return windowsill crop. Try sowing coriander, radish, chard, fenugreek and mustard seeds in a plastic takeaway food tray or a length of guttering and covering with a sprinkle of compost or vermiculite. Keep the compost moist and within days you'll be cutting handfuls of flavoursome greens to sprinkle on stir-fries, dahls and salads.
