Why do bay trees get yellow leaves?

(14 posts)

  1. Hi all,
    One of my farmingfriends readers Alan has a problem with his baytree, "could you please tell me what to do with my bay trees they have been moved out of pots into garden but now the leaves have gone yellow and started to look spindley" http://www.farmingfriends.com/bay-tree-problems-green-thumb-sunday/#comments
    I had a problem with my bay tree and got advice from TopVeg
    http://topveg.com/
    we even did a podcast!
    When I moved my baytree from it's pot most of the leaves fell off but my baytree is now revived thanks to the help of Topveg and had new growth this year. http://www.farmingfriends.com/index.php?tag=bay-tree
    My advice to Alan is make sure that the baytrees are in a sheltered spot as well as sunny.
    If anyone has any advice for Alan then please let us know. Thanks.

    I asked Topveg about this problem and they said it could be:
    too much water
    nutrition
    climate
    insects

    Topveg advice is "The infected leaves should be picked off & got rid of & badly affected shoots can be pruned out."

    Hope this helps.
    Kind regards

  2. Hi All,

    I have received an email regarding a baytree's leaves going yellow. Does anyone have any advice? I will ask topveg http://topveg.com/veg-questions/

    "I have 2 fine tall baytree standards I have grown from virtual twigs. There in big half barrells (each One) But at the underneath some leaves are going completely yellow. No black spots just yellow seems to be the young leaves other than that all looks very healthy?
    Thanks in anticipation.
    Anne Lea"

    Thanks

    Hi Everyone. My bays are about 30 ft tall and do have yellow leaves as do all evergreens at this time of year. Mine are growing in the ground and I don't do anything with them apart from hard pruning .Can not believe how much I used to pay for bay leaves to cook with.If any FF want bay leaves I will be happy to send some. Now my friends come and cut huge branches off to decorate the church with, saves me pruning too much.They do like full sun and well drained ground. Mama.

    Hi Mama, I have a bay bush which I hack back every couple of years and it just keeps coming!!! Lovely flavour for hams etc and wouldn't be without it. Fresh bay leaves have so much more flavour than the dried.
    Best wishes
    Sallie.

    Hi Sallie, Yes I agree but Delia does not. Don't care as we know best. Use them in everything , spag bol, ratatouille, and soup you name it. They are really moorish in anything. Regards, Mama .

  6. Hi All,
    Had this comment on my website about black substance on bay leaves.

    "I have two standard bay trees in pots and have kept them like this for three years. Recently, I have noticed a black substance on the leaves which washes off with just plain water but keeps coming back! Do you have any idea what this is? Or what I can do to prevent this reoccuring? Mia"

    Anyone know what it is or has any advice?

    I am sure that Topveg http://www.topveg.com will be able to help, I'll leave a reply there as well.
    Kind regards

    Hi, It sounds like Sooty Mould, you can get spray for this and it does clear it . Regards Mama

  8. Hi There!!

    We have asked our plant consultant Malcolm Allison about the problem Bay. He says:
    This would be a result of aphid infestation ~ the aphids secrete honeydew which provides a substrate & nutrition for the black mould. I'd recommend spraying the aphids with soapy water (or water with a bit of washing up liquid in it), hopefully this should deal with the problem.
    HTH!

    Thank you Topveg for the compliment or not ,I did not explain it in so much detail . I do have Bay ,Lemon, Olive and Orange tees and sometimes they do suffer from it. Done washing up liquid and to some extent it works but not always .What does HTH mean please . Mama

  11. Hello Mama

    It was meant as a compliment!
    Do you get a lot of aphids? I never imagine them to be in your warm part of the world! Good to know that the washing up liquid works some times. It must be wonderful to have your own lemons, oranges & olives!
    HTH is a phrase I learnt from Sara! Hope That Helps - which she always does! TopVeg

    Well thankyou again, yes we do get everything you get there only more of them. Some years are worse than others. I think the farmers have destroyed all the ladybirds as we are seeing less and less . Lot's of spraying goes on as it is agriculteral land all around us.they do everything with crop spraying planes so some of the stuff must fall on our fields. Shame it does not wipe out Lily Beetle, I squashed 60 this year. Regards Mama

  14. Hi Salad
    My daughter has got a bay in a pot - and it seems that REGULAR watering is the thing. As 'regular' seemed a bit of a problem for her - we changed it to 'water the bay on Mondays' & it seems to have done the trick - it now looks good & she has kept it going for several years.
    She still forgets, but having a special day helps to avoid overwatering. It always has 3 small watering cans worth at every watering. But the amount it needs depends on plant size, position etc..
    Hope you can sort yours out
