vicky s starts with ... Hi. I have six finger lime trees - one bought from the nursery [a daleys variety] and the other 5 i grew from seed 5 years ago or so. They are beautiful… One set flower for the first time two or three months ago and was COVERED in little fruit. Timing was all a bit tricky, as I had been meaning to move them to larger pots. I did, with lots of care, and they all have new growth ever since, but all the fruit has fallen. I suspected that might happen, and that's ok. The problem is that all of them have dieback at many branch tips. I have searched for insects all times of the day and before I go to bed, and although have found various critters I cannot see the thing that appears to be causing the problem. I am also not sure if it is a fungal problem as someone suggested. There is no fuzz, no particular colouring, nothing visible with the naked eye. When I rub them with my finger, nothing appears to come off - no sooty stuff, no whiteness. They are well watered and the recent re-potted to larger pots has not solved the problem [before that i thought the problem might have been them being potbound, but the problem persists]. They do have lots of new growth, but that also turns browny sometimes. I have attached three photos that show the details. PLEASE help!

Peter91 says... Do you have a free draining soil mix? The only time I had a dieback was when I messed up a mix, switched to a free draining mix again and they're sprouting new growth again already. Free draining soil is essential, only other thing I could guess would be the acidity level. Sorry I can't offer more insight than that. | About the Author Peter91 North Plympton 14th December 2015 10:42pm #UserID: 11892 Posts: 111 View All Peter91's Edible Fruit Trees |

vicky s says... Hi Peter91 and Bangkok. Thank you both for your replies. I am not sure if this is where I'm supposed to respond, so hopefully you'll receive this message. I'm wondering if you think a native potting mix is free draining enough? I used a good quality mix that's sold in 25 litre bags at nurseries Etc. Also, do you know how acidic the soul should be for seed-grown finger limes? And if the trees have new growth, is it still possible or likely to be either of those problems? Many thanks again. | About the Author vicky s ELTHAM VIC 16th December 2015 7:12pm #UserID: 12878 Posts: 2 View All vicky s's Edible Fruit Trees |
Waterfall says... I'm not sure if this is your issue but you should know that grafted finger limes are on a standard citrus rootstock like trifoliata. So you would choose a potting mix like any other citrus tree not a native soil mix. In my experience a straight potting mix does not drain well in containers and should be mixed with up to 50% washed river sand and or pearlite. | About the Author Waterfall WATERFALL,2233,NSW 17th December 2015 9:38am #UserID: 10026 Posts: 422 View All Waterfall's Edible Fruit Trees |
Bangkok says... I have 2 fingerlimes that i bought here on unknown rootstock, they almost don't grow and get eaten totally all the time. The branch that i grafted onto pomelo and in full sun grows very well though but also has dieback issues. That's no problem though because it will make new branches nonstop. I guess pomelo is different than other citrus, i have a big bowl under the pot and regularly fill the bowl with water. I put a wick in the bowl made of microfibre towell (just a 3 cm wide strip) which hangs in and over the bowl to drain the bowl very slowly. Also it gets a lot of fertilizer. I had another pomelotree in full soil which survived our big flooding, it was in 40 cm water for 2-3 weeks, same as my mangotree who survived that. So you can't really compare my situation with yours i guess. Pomelo is different then your rootstock and so is our climate here. The strange thing is that nothing eats my fingerlimeleaves on that pomelo in full sun. The other small tree's in more shade have bugs eating them nonstop. | About the Author Bangkok Thailand 17th December 2015 1:21pm #UserID: 11594 Posts: 370 View All Bangkok's Edible Fruit Trees |
