Jobs for the yard in September

With Brownie

  • Grow any herbs now – except for basil (it’s too early) and coriander (it’s too late).
  • Grevilleas will be flowering away. Cutting flowers for inside the house will promote new growth and better plant health.
  • Pruning of edible fig trees can be carried out. Be very vigorous – one-third can be cut off. Figs are only produced on new wood of the new season’s growth. Give them a good feed of general fertiliser.
  • It could be a few months before we get good soaking rains and the drying September winds will suck the moisture from bare soil, so mulch your gardens to keep in the available water.
  • Dig up and divide canna lilies. Water them in well with a seaweed solution.
  • It’s a good month to start the fruit orchard – plant mango, pawpaw, avocado, custard apple, carambola and sapodilla.
  • Spray your flowering mangoes with Mancozeb or a copper-based fungicide to prevent the disease anthracnose.
  • Poinsettia cuttings can be taken now to pot up and grow new plants to be given away at Christmas.
  • Watch out for rampant lawn weeds – especially bindi-eye, clover and flatweed (or cats ear).
  • Plant potatoes and sweet potatoes in the vegetable garden – although watch sweet potatoes as they can be vigorous and will take over. Mound up soil around potatoes already growing to promote more growth.
  • If you haven’t pH tested your soil for a while, do it now. Excessive acidity or alkalinity will interfere with uptake of nutrients by plants. The perfect range is 6.5-7.5. Remember never to apply lime at the same time as fertilisers as this leads to a loss of nitrogen, caused by it converting to ammonia and gassing off. Allow three weeks between liming and fertiliser applications. Never add lime to a compost heap as this also leads to a large loss of nutrient into the atmosphere.
