  • Last week I suggested drenching your Pencil Pines with Confidor or Rogor to eradicate the pernicious "Cypress Bark Weevil" however it seems that the term ‘drenching’ is not widely understood in urban Adelaide (not enough Cockies sorry read that as farmer and grazier if you are not Australian) out there these days eh?). Anyhow that just means to mix the recommended strength of Confidor or Rogor and water it into the area of the root zone. You may need to scratch around to find the small feeder roots, but they take the active agent up quickly and zappo to the borer larvae inside!
  • Vine caterpillars are starting to multiply rapidly at present and can be controlled by spraying the Baccilus thuringiensis which infects the caterpillars’ stomach and while it kills them, the predatory birds and insects that eat the dead caterpillars do not get affected. Marketed as Dipel® H.G. bio-insecticide.
  • If it you want to protect other sorts of caterpillars or moths that frequent your garden, then only spray Dipel® onto the target vines and then your orange Monarchs will fly free.
  • It’s time to plant spring onions now for those salad days and here’s how. Remove 10cm (4") of your topsoil and put it aside, then spread superphosphate at 200 grams per square metre over the area you want to grow your onions, then replace top soil and line out your ‘Lisbon White’ spring onion seedlings on top.
  • If you are looking for a few hints on controlling the bugs in your garden at present that do not rely on sprays, try planting Nasturtium seed near your vegetables and fruit trees, where they can scramble up a fence or over the ground.
  • Also plant any of the old-fashioned geranium or pelargonium shrubs under or near your apricots and peaches. I saw these in Allan & Muriel Norton’s pest free organic Black Forest SA garden recently and they reminded me reminded that I’d advised them after having seen the results in an old mallee garden many years before. What goes around comes around eh?

  • If your parsley is bolting to seed at present, there’s nothing to do other than plant some more seedlings or sow some seed. It is a biennial and will flower after two years then die out, but best practice is to plant fresh seedlings every year then you have a seamless supply.
