December is a good time to...
Dig up your new potatoes for Christmas lunch or dinner.
Plant flowering annuals, like red and white petunias and impatiens, for the festive season. Impatiens are perfect for growing in a shady spot and petunias thrive in the sun. Avoid too much watering to prevent the plants rotting.
Keep planting your gourmet veges (like fancy lettuce and spinach) and herbs (like basil, coriander, and rocket) so you have a continuous and regular supply.
If you haven’t already, apply pea straw mulch on your vege, herb and flower gardens. Watch out for aphids. Start deadheading your roses for their next flowering in autumn. If they’re hybrid teas, cut them back to where the branch is as thick as a pencil – so the next shoot that grows from there will have enough growth to produce a flower. Prune back your spring growth on hedges and topiary balls.
Remember to keep watering and make sure you do it in the morning, not at night, so the sun has a chance to dry the moisture off your leaves. If you water at night the moisture will rot the leaves overnight. If your pot plants look like they’re getting a bit dry, put a thin layer of stones on the top of the soil to retain the moisture.
If it’s really dry around your tomatoes, put a thin layer of newspaper and then some compost on top to keep the moisture level steady. Stake your tomatoes. Avoid tipping water on their leaves so as not to cause blight.
