Your March Gardening To-Do-List

March is known as maintenance month and its also the perfect month to start sowing autumn and winter crops. Make sure you are setting yourself up for an abundance of tasty winter veggies and keep your autumn garden looking good! 

Garden To-Do-List

  • Pull out any of your spent annuals and old perennials and give those beds a good tidying. 
  • Prepare your soil for your seasonal bulbs by loosening the soil and mixing in manure and bonemeal. 
  • Keep your eye out for pests on your neriens, clivias, amaryllis and fire lilies and be sure to spray when necessary! 
  • You can adjust your watering system in March to accomodate for the drop in temperature and shorter days. 
  • Be sure to feed your fruit trees in March. 
  • Give your roses a generous feed this month to strengthen their stems. You will also want to clip any deadheads and spray any fungal problems now. 
  • Nerines and Tibouchinas should be in full bloom this month, so keep an eye out for them when popping in at 4 Seasons! 
  • Be sure to feed your lawn to keep it green and healthy going into winter.
  • You will also need to feed the rest of your garden with organic-based fertilisers in March. 
  • Be on the lookout for pests like red scale and whitefly – they are more active during the cooler months of the year so you will need to protect your plants. 
  • You will also need to check for scale along the stems and on the leaves of citrus trees. 
  • Dust bulbs with insecticide spray to protect them from worms.
  • Now is the time to divide your agapanthus, wild irises, penstemon, campanula and asters. 
  • Lightly trim plants that may be out of shape or overgrown this month so that you can give them some time to harden up before the cooler weather comes. 
  • Remember to compost areas where your soil needs nutrients for new plants. 
  • Make sure to mulch around azaleas, hydrangeas (not the pink ones tho) and camellias with an acidic compost to keep the roots cool and moist this time of year.

Be sure to clean out your water feature this month – you won’t want to do this when the weather gets cold! Also clean your pump and make sure its in good condition.

What to Plant

  • Leafy winter veggies like kale, lettuce, spinach and your root vegetables such as carrots, broad beans, beetroot and radishes can all be planted in the vegetable garden now. 
  • Your cool-season herbs such as chives, rocket and calendula can also be planted this month. 
  • Sweet peas, hollyhocks, primulas, poppies, pansies, and snapdragons can all be planted in March. 

What to Sow

  • Indigenous annuals like Namaqualand daisies, nemesias, felicias, heliophila (blue flax) and ursinias can all be sown in the garden now. 
  • You can start sowing broccoli, cabbage, cauliflower and kale this month.
  • Since the soil has cooled down sufficiently by this time, you can buy your winter and spring bulbs like freesias, ixias and sparaxis now and start sowing them! Ask Nicol for guidance for your particular garden.
