Winter needn’t mean downtime in the garden. Take the opportunity to grow seasonal veggies and add some colour to your plot in June.
        Plant and sow
        • Plant cool-season bedding plants such as alyssum, calendula, dianthus, lobelia, nemesia, pansies, sweet peas and violas.
        • Liliums, azaleas and camellias can be planted in dappled shade.
        • Sow winter vegetables such as Brussels sprouts, kale, radish, leek, onion, turnips and members of the cabbage family (broccoli, cabbage, cauliflower and spinach).
        • Feed lemon trees with 3:1:5 or 8:1:5.
        • Remedy yellowing leaves with a micro-element mixture such as Trelmix.
        • Feed bulbs with bulb food once every two weeks and water well.
        • Winter and spring-flowering seedlings require 3:1:5 every two weeks with a weekly watering.
        • Check the edges of sweet peas. If they’re brown and papery, feed with 3:1:5.
        • Feed indoor plants with nitrosol weekly.
        • Remove side shoots on sweet peas to encourage strong upward growth.
        • Trim autumn-flowering shrubs like pride of India, ribbon bush, wild dagga and barleria.
        • Prune fruit trees such as peach, plum and apricot.
        • Spruce up hydrangeas.
        • Prune roses after transplanting.
        • Now is the perfect time to prepare holes if you’re transplanting your roses as they are dormant during winter.
        • Spray with lime after planting and pruning.
        • Keep an eye out for leaf miner on cinerarias and spray with Bioneem.
        • Spray conifers with Koinor or Bioneem to ward off aphids, or water in insecticide granules at the base of the tree.
        • Use organic snail bait for snails on clivias, daffodils and young seedlings.
