Yellow leaves

I have a 3yr old Victoria plum tree which this spring and summer produced quite a few yellow but sound leaves (about 60-70). They do not appear diseased and eventually fall to the ground. Can anyone advise me what can be done please?

    Is the rest of the tree OK? I have just been watching a jackdaw, for no reason other than boredom, twist various leaves on my Blenhein Orange apple tree until they are loosened.

    Apophthegm -  a big word for a small thought.
    If you live in Derbyshire, as I do.
  • It is maybe short of minerals such as iron or magnesium or needs a general fertilizer....although this should have been applied earlier in the season.

  • I applied some Miracle Gro Shrub and Rose food in the spring (has high nitrogen content) so thought this would be adequate for the year. Do you think I should put another light dressing on now or wait until next spring?

  • Hi, Angela....I think we need to think where we are in the season. At this time of year it isn't usual to feed high nitrogen feed, which will promote new leaf growth that (because of their tenderness) may get damaged by winter frosts.

    It would probably be preferable to feed 'Growmore', which is equally balanced in all three nutrients i.e nitrogen, phosphates & potash, followed by a mulch of garden compost or well rotted manure.

    I note that 'Miracle Gro Shrub and Rose food' has an NPK rating 5-11-15, which being high in nitrogen & potash would make it an ideal spring feed.
