Ilijas starts with ... This is a young shoot on my potted West Indian Lime, and it seems to be going yellower and yellower. I applied some chelated iron solution about 2-3 days ago thinking it was chlorosis. I haven't seen a difference yet, and now thinking it may be something else. Could this be something other than chlorosis, or should I just way for the iron solution to get soaked up by the lime?

amanda says... My WI Lime is the same - the new leaves are yellow - no veining... Mine needs some nitrogen -but like Julie said - it's also the cold that slows them down... Iron chelate to the leaves should work fine tho - as it bypasses the cold soil... I'd check the pH of those pots and wait another week (or follow instructions on pack) If it doesn't improve then try some liquid fertiliser for a bit maybe...don't overdo it to compensate tho...(as you may burn it - but also it may not be growing much at the moment..?) | About the Author amanda19 Geraldton. 400km north of Perth. 24th July 2012 9:17am #UserID: 2309 Posts: 4607 View All amanda19's Edible Fruit Trees |

Xiem says... Yes I am having trouble with a Julie seedling at the moment - nothing I do seems to green the leaves, including peeing on it and wiping the leaves with epsom salts. Other citrus in pots nearby are fine. I suspect it is too much attention, with a build up of salts so that the plant can't take up the particular minerals it needs. I guess sufficient time must also be allowed as suggested by Julie and Amanda - when something is added to the soil I think one needs to wait a few weeks before any results are obvious and before any other treatment is considered. I tend to be impatient and don't wait long enough. | About the Author Diego 24th July 2012 12:27pm #UserID: 4715 Posts: 283 View All Diego's Edible Fruit Trees |

Ilijas says... Not really sure. They both seem to be growing from their tips. The WI lime on the pic is a brand new branch from the last 2-3 months, and it's the only one with the yellowish leaves. Both the WI lime and the Julie seedling Seville are in a very warm spot up against the house facing north. I've done the iron chelate once, so I'll leave them alone for the time being, I guess. The potting mix that they're in is one that's specifically for fruit trees - not that I'm really sure that it's that different from other potting mixes. | About the Author Ilijas Melbourne 24th July 2012 10:25pm #UserID: 6805 Posts: 29 View All Ilijas's Edible Fruit Trees |

grub says... Check the ph are you watering with bore water ?.if you want to bring the ph down quickly use aluminuim sulfate .you will have to get the guide for the correct dosage ,sorry could find the link,sulfur will slowly bring it down as well ..iron chelate is useless if your ph is not right ..and give it some trace elements citrus need this 3 times a year | About the Author grub 28th July 2012 4:30pm #UserID: 3828 Posts: 47 View All grub's Edible Fruit Trees |

grub says... hi julie didnt relise you were in wa mine looked like that last year ...id say you are right i also had a nitrogen problem once i corrected the ph the plants doubled in sise that summer .7.5 ph is 100000 more alkiline than 6.5 dosnt look much on the chart but once your told how important the ph is to citrus i took notice ,my was 7.5 and my bore water was 8.5 so i had to drop mine down to 5.8 and what a diffrence it made ...i with you on the alliminum aswell .. | About the Author grub 29th July 2012 10:01am #UserID: 3828 Posts: 47 View All grub's Edible Fruit Trees |

amanda says... That's a good point grub - the pH of our tap water here is 8.5 also...(that's my irrigation water as well)so it doesn't help things at all..grr! I gave my tangello a big post harvest prune, some iron and zinc sulphate and some dynamic lifter a month ago - as it was in need. It hasn't sprouted new growth yet - but the current leaves are slowly becoming a darker green... Julie is right though - it's very cold this winter and too much feeding would be a waste for sure... My tree's are not getting a lot of water as they don't need it right now - so leaching wouldn't be an issue... | About the Author amanda19 Geraldton. 400km north of Perth. 29th July 2012 11:43am #UserID: 2309 Posts: 4607 View All amanda19's Edible Fruit Trees |

Slicko says... I have a Myer lemon that over the last few weeks is showing increasing chlorosis. Perhaps 20% of the leaves are affected and there is now quite a lot of leaf fall. There is a crop of immature fruit (affected by melonase) and there is also one set of unopened flowers. I have given it two treatments of iron chelate and one of trace elements and the chlorosis continues to increase. Ph is 6.8 Does anyone have any suggestions as to what I can do to assist its recovery? My five other citrus are also in the ground and doing fine.

Markmelb says... This is due to your cold nites too up there - Myers older leaves do that all the time - then drop - chelates usually only works well on fresh growth and partially on existing - will be a different plant in spring - Ive started using a liquid Iron Chelates from Bass Laboratories 20 drops per litre water with better results easier uptake. | About the Author Markmelb MT WAVERLEY,3149,VIC 15th June 2015 6:40pm #UserID: 7785 Posts: 1192 View All Markmelb's Edible Fruit Trees |

Thithi says... If the yellowing of leaves affects older leaves first and leaves veins are yellower, then it is more likely lack of nitrogen rather than lack of iron. http://www.dpi.nsw.gov.au/agriculture/horticulture/citrus/management/nutrition/nutrition http://www.globalnetacademy.edu.au/listen-to-your-lemons-what-are-your-citrus-trees-trying-to-tell-you/ http://www.ipm.ucdavis.edu/PMG/C107/m107bpleaftwigdis.html | About the Author Thithi MELBOURNE,,NT 15th June 2015 7:24pm #UserID: 10139 Posts: 193 View All Thithi's Edible Fruit Trees |

Thithi says... I Don't have Myer lemon, but has a few limes and lemon trees, they are quite cold tolerant though. I did apply a few handful of citrus food for my eureka and sublime and a few other citrus trees roughly about a month ago, I noticed today that the sublime tree produce lots of flowers and eureka has new leaves while others do nothing. I will pay attention to whether its young leaves will die A while ago I was advised to not to fertilise deciduous trees in winter and reduce to half of the fertiliser for evergreen. I think a bit of chicken manure or decomposed mulch would be ok. To slicko, I think removing the yellowing leaves would make it is easier to observe the effects of whatever treatment you'd give to the tree, these leaves would drop anyway | About the Author Thithi MELBOURNE,,NT 15th June 2015 10:30pm #UserID: 10139 Posts: 193 View All Thithi's Edible Fruit Trees |

Markmelb says... Great answer Thi - Meyer are the first to show yellow leaves at beginning of Winter or anything for that matter - I pull off yellow leaves too and use as mulch around pot - my belief is they are meant to be there but not into leaving fruit on ground to rot - there must be iron in them thar leaves? | About the Author Markmelb MT WAVERLEY,3149,VIC 15th June 2015 11:01pm #UserID: 7785 Posts: 1192 View All Markmelb's Edible Fruit Trees |

Slicko says... That is interesting. I would not have expected cold weather to cause chlorosis especially in Myer lemons. I understand that it can be caused by insufficient iron affecting the uptake of nitrogen and can be dealt with by the use of iron chelate, but I am surprised none the less. We have had a few low temperatures of the past few weeks and there are more expected from this week so I should expect to see more yellowing. I guess that you would see more chlorosis in the southern winters than we would see here. Ph is 6.8 so I have to do some work here also. Thithi, thanks for those links. I had been looking for a site that had pics of leaves with different mineral deficiencies for some time. They will be handy indeed. Going to take those yellow leaves off and monitor things from there. | About the Author Slicko CARINDALE,4152,QLD 16th June 2015 9:44pm #UserID: 1775 Posts: 227 View All Slicko's Edible Fruit Trees |
