  • THE BEST HOSTS EVER!!!

    Gardening Talkback is co hosted by Greg Richard, Mark Rorke, or Amanda Macreid and the gardening experts are Judy Sharp, but if Judy is unavailable her son, Scott Sharpe will fill in for her. They used to own a gardening business but they have since sold it. Judy is my favourite out of Scott and Judy because not only is Judy an expert, she has a warm gentle manner and is a very nice lady. The way she talks to people on the phone when gardening talkback is on is super polite, friendly, and cheery... more

  • Always look forward to this show

    I can never get enough gardening advice, especially as I live only a couple of hours further up the coast. Very practical, no nonsense advice is given and there are no advertisements to intrude. My only complaint is that it should run for an hour! Thank you for the show.

Hippeastrum, roses, cockchafers - 19 October 2026
Q: How many gladiolus bulbs can Joy plant in a pot about two and a half feet wide, and is it too late to plant them?
Judy recommends planting two or three bulbs and says it is not too late because gladiolus bulbs are fairly tough.
Hippeastrum, roses, cockchafers - 19 October 2026
Q: What should Paul put on his bird of paradise plants to help them flower?
Judy recommends sulfate of potash and suggests that it should help the plants flower.
Christmas is coming - 26 October 2026
Q: How do I prevent sawfly larvae from getting onto my cherry trees in the first place?
Judy Sharpe says prevention is difficult and advises watching the trees closely, then spraying with malathion and possibly white oil when needed.
Christmas is coming - 26 October 2026
Q: My passionfruit vines have flowers by now. What should I do?
Judy Sharpe says the erratic weather may be delaying flowering and advises waiting for warmer weather, continuing appropriate fertilising, and adding a little cow manure without overdoing it.
Magnolia - 03 August 2026
Q: What is good to fertilize a lemon tree to make it bloom and productive?
Feed citrus trees year-round with poultry manure, but avoid applying fertilizer when the tree is actively flowering to prevent pushing too much growth at the wrong time; for older trees, a boost with sulfate of potash prior to flowering helps improve fruiting and flowering.
