Db starts with ... I hope someone can help me. Some of my potted young fruit plants are getting leaf edge burn and they are getting dropped. At this stage this issue seems to be only for 3-4 young leaf on the tip of the branch. Custard apple, raspberry n Hawaiian guava are affected. Most of the leafs of guava n raspberry are shrivelled as well, so I'm worried. Potted Mexican cream guava sitting next to hawaiian seems to unaffected. They all are potted 2 months back, all were growing very nicely untill recently. All regularly got seasol (once a fortnight), no other fertilizers apart from what was in my potting mix at the time of purchase. I don't think it's due to sun-burn as they r getting less sun now a days since this issue started. They getting same amount of water as before. What could be the issue and any solution? Could it just due to colder nights now a days? Or do they need any fertilizers? I don't have photos now but I can upload it tomorrow if required. | About the Author Db Brisbane 19th April 2012 7:36am #UserID: 6427 Posts: 470 View All Db's Edible Fruit Trees |

Brendan says... Hi Db, try to make sure that the fertilizer (you use) does not have too much nitrogen, that makes the leaves too soft and tend to burn easier. On the other hand, P & K fertilizer hardens up the tissue of the plant (& leaves) :-) Don't forget the liquid gypsum, it could be sold as Groundbreaker? | About the Author Brendan Mackay, Q 19th April 2012 8:14am #UserID: 1947 Posts: 1722 View All Brendan's Edible Fruit Trees |

Db says... Here are the photos issue mentioned above. 1st pic is Heritage Raspberry, 2nd is Hawaiian guava, 3rd is PP custard apple.. All in pot since last 2 months.. Even my Panama berry (in last photo) is also yellowing and dropping leaves everyday, it gets some black spots first and then starts yellowing Could it be just due to cooler nights but they are supposed to evergreen so I'm confused.. Hawaiian guava may not be showing leaf burn in the photo as those leaves are already dropped in last few days as you can see, leaf curling is another issue I'm facing with this one..

BJ says... Dont worry about the Panama Berry. They drop lots of leaves and look a bit scruffy in the cooler months, but come back in spring. They are evergreen, but not always green. You can ease up on feeding anything to the atemoya and raspberries, unless you are trying to feed fruit on the trees, which you obviously wouldnt be doing at this stage. Also, the panama berry tree grows great in the ground without any additional care. They are just so-so in a pot, even with lots of love and care. They are a nice soft wood that is so easy to cut back if its getting too big. | About the Author Theposterformerlyknownas Brisbane 20th April 2012 8:45am #UserID: 3270 Posts: 1552 View All Theposterformerlyknownas's Edible Fruit Trees |

Db says... John - thanks for reply.. Only pesticides it gets is Pyrethrum, fortnightly.. But out of around 25 fruits trees only these 3-4 have this issue now. Drainage could be the issue as I may have over-added water crystals in some of the pots (but its not the case with Hawaiian as I planted it well before getting water crystals).. BJ, thanks for reply.. So I'm confused now.. Should I give them liquid potash or not? | About the Author Db Brisbane 20th April 2012 8:50am #UserID: 6427 Posts: 470 View All Db's Edible Fruit Trees |

Db says... I used Yate's Pyrethrum, so diluted as per bottle instructions. But bottle is now empty. As this pyrethrum was not that useful on some of the plants like Tamarillo n I have to apply it more frequently on all plants, last week only I have bought Yate's Maverik which I believe is more concentrated than pyrethrum. I have not used it yet but now I'm bit scared to use it if pyrethrum was the real issue here. | About the Author Db Brisbane 20th April 2012 9:40am #UserID: 6427 Posts: 470 View All Db's Edible Fruit Trees |

BJ says... I'm fairly certain its only a problem in the tropics, and even then only certain trees become problematic. I've had thousands of fruit cover the ground under my tree and they dont germinate. I've heard it takes a hot box in full sun to get the seeds to germinate. So bottom line is that they should be less of a problem than any other fruiting plant in the yard. | About the Author Theposterformerlyknownas Brisbane 20th April 2012 11:59am #UserID: 3270 Posts: 1552 View All Theposterformerlyknownas's Edible Fruit Trees |

davewastech says... Hi Db, It would be interesting to hear more about how your Panama Berry is doing. Mine is going yellow recent week or so just like the one in your photo. (Mine is 2.5 years old, planted in clay soil in level ground in Sydney. Flowering at the moment. Fruited last summer and autumn) | About the Author davewastech WILLOUGHBY EAST,2068,NSW 22nd December 2015 10:36am #UserID: 7097 Posts: 115 View All davewastech's Edible Fruit Trees |
