Yellow leaves on plum tree
Hi all.
I have a 4 year old vic plum planted last year. some of the older leaves are turning yellow. Would I be right in thinking this is due to lack of nitrogen? The tree is planted with grass right up to the trunk, so I thought I would use a liquid nitrogen feed. Thanks Peter |

A little Miracle Grow around the tree wouldn't hurt. It is generally not a good idea to have grass, or anything else growing within the drip line of the tree. It takes energy away from the tree. Yellow leaves could be indicative of a more serious problem. If the leaves turn this color in the fall, this could be a sign that the tree is going dormant or dying. Check the base for entry holes of borers. You did not give your location and type of soil, which could give more clues to the problem. Did you get a lot of rain this year, and does your soil drain well? Sherwin |

The yellowing of leaves is called Chlorosis in normal green plants. http://en.wikipedia.org/wiki/Chlorosis As for using "liquid nitrogen" requires careful use! In a science class "liquid nitrogen" was used to dip a rose in it and then smashed on the table. The rose shattered like glass :) Very Cool Huh :) Enjoy Life ...

The article you referenced says that iron chlorosis usually shows up on the younger leaves first, then the older leaves. This might indicate their other suggestion of manganese or zinc deficiences. I would still not rule out other possiblities, like over watered roots or the tree going prematurely into dormancy because of some disease or insect damage. The original poster has left out many details, like is this yellowing on all branches, or just certain ones, etc. Sherwin |
Thanks for all the replies, I've been away the last few days. I'm based in the UK, Midlands. So we've had some heavy rain recently, but also allot of sunshine, for the UK at least. The soils is a little sandy, so drains quite well. The yellowing of the leaves is not on this years new growth at all & mainly on the older leaves. I've also noticed this morning that a few plums have dropped also.
My idea of lack of nitrogen was based on a quick search on goggle, as I didn't think it was water logged & got plenty of water. I did mean a liquid fertilizer that also contains nitrogen. I don't plan to have my plum tree cryogenically frozen. Thanks |

Thanks If you have other similar plants nearby with or without the same problem, it could be a soil deficiency of minerals. Here in the USA, we have a product called Miracle Grow, a liquid fertilizer, but you must have something like it in Britain. The tree may be in trouble for other reasons. Check for insect attacks (borers at the soil line). Again, is this on all branches or just particular ones? This could be a climatic thing, and if so, the tree should come back ok next year. Are there any damages to the leaves besides yellowing, and does the fruit look normal? The web site posted indicated that older leaves turning yellow was a possible sign of zinc or magnesium deficiency. Sherwin |

Maybe there is a college or university near you that is familiar with your regions flora and fauna, huh? -- - Billy There are three kinds of men: The ones that learn by reading.

Gee, he could have saved a lot of time by just bypassing this forum and going directly to his nearest 'experts' location. This to me is just a cop out when you have no knowledge of the subject matter. Sherwin |

Hi i'm new on here (first post) i have a similar problem with my plum tree, not sure of it's age as it was in the garden when i moved in, only small though after a couple of years of cutting it back, i'm now letting it grow. any way i recently came back from holiday to find my tree which was lovely and green when i left, all the leaves turned yellow and drooping, the new growth is still green though, i think it may be a fungus as the bark is coming away and i can see fungus on the outside, also a few insects scuttling around. i like the peter am in the midlands the tree has been fed this year obvioulsy was no fruit as all new growth |

So if older leaves are going yellow it is more likely to be a fruit tree disease than poor feeding. My first thoughts are apple scap or a blight of some sort. Both are fungal and there are no fungicides that you could use this late and still eat the fruit. So if you spray, you don't eat. If you do not spray, clean up the leaves and other rubbish under the tree in the autumn and burn it or dump it. Do not put it on your compost heap. That way you reduce the chances of the disease overwintering. Good luck |
Hi I'm back, didn't realise other people had responded since I last looked. The issue seemed to go away with feeding, however around a week ago the tree started to show blotchy yellow & green leaves. Shown a look at the below link.
P.s when did Picasa stop doing hot links! http://picasaweb.google.co.uk/petern...70669558187618 |
