Yellowing Azaleas
Hi Everyone
Have some Azaleas that are starting to yellow a little. They had early signs of Azalea Lace bug, which I dealt with. I don't think the yellowing is linked to the lace bug, as not all had the bug. My only guess is the ground is too wet. Would this cause it? The yellowing was first noticed about a week and 1/2 ago, and previous to that we had about 2 weeks of drizzling rain, and the ground has been quite wet. I gave them a dose of liquid fertiliser just to hopefully boost them before spraying for the bugs. Thanks for any help. -- Remove "not" from start of email address to reply |

Hi Andrew I dont know if this will help, Im no gardening oracle but when my Gardenias go yellow I have been told it is due to iron deficiancy. I give them each a jolly good handfull or two of epsom salts each and within days the yellowing has gone... but as I say, thats for my gardenias, not sure if it relates to azaleas but its worth a shot.

(From the book) Yellow leaves on azaleas are often from lime-induced chlorosis, so have you been doing any concreting, or spread lime anywhere else in the past 3 months? Maybe the rain washed it onto the azaleas. The symptoms are yellowing of the new growth especially, with the main veins often staying green (iron deficiency). It also mentions phytophthora. The symptoms for that are leaves yellowing on one branch first, leaf drop and dieback. Mottled yellowing is probably due to lace bug. HTH Jane |

u... (From the book) Yellow leaves on azaleas are often from lime-induced chlorosis, so have you been doing any concreting, or spread lime anywhere else in the past 3 months? Maybe the rain washed it onto the azaleas. The symptoms are yellowing of the new growth especially, with the main veins often staying green (iron deficiency). Will check the "vein" thing tomorrow. Did some concreting in one part of the garden, but other parts are nowhere near the concreting. It also mentions phytophthora. The symptoms for that are leaves yellowing on one branch first, leaf drop and dieback. This could be a possibility. I lost the leaves last year around the same time after yellowing, to the point you could swear they were deciduous. My g/f beleives the ground was too wet back then, she may be right. I just thought the loss was due to the lace bug as I didn't spray for it last year (Rogor not being a favourite of mine) But Phytophora is a root rot IIRC. So quite possibly this is the case. Thanks Jane, for the help, thanks too flossie. -- Remove "not" from start of email address to reply Mottled yellowing is probably due to lace bug. HTH Jane |

Yellowing Azaleas
You said - " I have some Azaleas that are starting to yellow a little." This is a classic symptom of a plant about to make new growth, (ie - not a problem), possibly because of the recent rain. It is also that time of the year when Azalias start to 'grow and shed' for their pre-winter flowering. Sit back and observe! And maybe another feed in a month or two, this is my experience.

Ahhh, ok, thanks for this Could explain why they are ALL doing it, and why they did it last year, then came back without help. I was just hoping I could stop it this time :-) Oh, and probably why the ones at work seem to be doing it too. Hey, you aren't that far away, I'm in Forster :-) Hope you are getting the rain out your way, and more. Actually, hope many of you are getting some of this current, and "next few days" rain -- Remove "not" from start of email address to reply China Wingham NSW |
