MandaB starts with ... I have planted two avocado trees and both have died the same way. The leaves start to droop then about a month later they drop off rapidly and I am left with a stick in the ground. The stem doesnt appear to be dead yet and one of them hasnt had leaves for three months now. The second has just lost its leaves. I have sprouted a seed and want to plant it but want to know if there is something I can do to ensure it survives as this is getting expensive! | About the Author MandaB Brisbane 8th January 2011 10:43am #UserID: 4759 Posts: 8 View All MandaB's Edible Fruit Trees |

Phil@Tyalgum says... Avocados are very prone to dying in very wet weather. If their roots are waterlogged at all, they will turn up their toes quickly and not recover. Either create a raised bed or another option is to plant the tree in a very large pot and allow the roots to grow down into the ground through the drainage holes (in its permanent position) and you should have fruit in two or three years. A lot of commercial avocado growers use this method to prevent their trees from dying in wet soil. http://www.abc.net.au/gardening/stories/s1939805.htm They can also get sunburnt, especially newly planted trees and the young stems get fried in direct sun. One solution is to paint the trunk with white waterbased paint until the tree becomes more established or provide some shade. | About the Author TyalgumPhil Murwillumbah 8th January 2011 12:09pm #UserID: 960 Posts: 1377 View All TyalgumPhil's Edible Fruit Trees |

Brendan says... Hi MandaB, sounds like your trees have Phytophthora Root Rot. It's probably too late, but you could try spraying them with Yates Anti Rot and giving them lots of Gypsum. They might come back. I've planted mine on mounds, as Phil says, and two of mine look sick too. We've had record amounts of rain in the last 3 months. | About the Author Brendan Mackay, Q 9th January 2011 8:48am #UserID: 1947 Posts: 1722 View All Brendan's Edible Fruit Trees |

BJ says... I dont think you can ever kill phytopthera. The sprays knock it back a bit and allow your trees to strengthen themselves against it for a while, but it will come back, so you need to spray every so often, especially during/after wet periods. Good luck with your avocados. My Hass has been snapped in half twice in a week with the storms here. | About the Author Theposterformerlyknownas Brisbane 18th January 2011 8:43pm #UserID: 3270 Posts: 1552 View All Theposterformerlyknownas's Edible Fruit Trees |

Brendan says... MandaB, My Wurtz avo died about 6 years ago because of phytophthora root rot, and being planted in a very wet area. About 1 metre away from that spot, I planted a Lamb Hass on a mound, and it's powering along. The photo shows it at ~ 1 year old. I added lots of gypsum to the mound also. Because gypsum helps with drainage, it's a natural enemy of phytophthora.
