Winter needn’t mean downtime in the garden. Take the opportunity to grow seasonal veggies and add some colour to your plot in June.
ON YOUR TO-DO LIST
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.
