#HarryB Posted October 30, 2020 Report Share Posted October 30, 2020 Does anyone have something that really works? We have tried everything, we think! We even tried an old recipe by one of the highly respected oldtimer gardeners. Our gardenias are almost dying. The hibiscus croniclly have yellow leaves. We are taking off the infected leaves and keeping the pots clean. Roses and hydrangeas are infected and the granada too. Bird of Paradise seem immune HELP !!!!!!!!!!!!!

ajijicbound Posted October 30, 2020 Report Share Posted October 30, 2020 We had a speaker at our garden club and she swears by this product. I have seen it at the viveros or mercado libre. http://lakechapalagardenclub.org/speaker.fungi.html Quote Link to comment Share on other sites More sharing options...

I have been experimenting with fresh coconut water that I buy locally, diluted 100 ml to 1 litre of water and sprayed on foliage with a pump up sprayer. It so far has controlled it on hydrangeas, rosemary and mostly controlled on poinsettia tree. In Canada I used trichoderma fungi germinated as well as Japanese knotweed watery infusion.

timjwilson Posted October 30, 2020 Report Share Posted October 30, 2020 PS - it was powdery/downy mildew. Quote Link to comment Share on other sites More sharing options...
#HarryB Posted October 31, 2020 Author Report Share Posted October 31, 2020 The leaves turn from green to green with yellow spots. Then they go totally yellow, eventually the plant dies. Thanks for the ideas! Harry Quote Link to comment Share on other sites More sharing options...
JKL Posted October 31, 2020 Report Share Posted October 31, 2020 We have a poinsettia tree that starts out each year looking great. It is currently in full bloom, but as usual, the leaves have white spots all over them which I guess is a fungus. We've tried all kinds of sprays, cutting it back, and still it looks terrible even though it has beautiful red blooms. Could it be that it just isn't getting enough full sun or does that have anything to do with it? We've seen many Poinsettia trees around town thriving on neglect. Ideas???

sm1mex Posted October 31, 2020 Report Share Posted October 31, 2020 Check with the garden store just east of 7/11 in Riberas lake side. Take in some infected leaves to show her. Quote Link to comment Share on other sites More sharing options...
bmh Posted October 31, 2020 Report Share Posted October 31, 2020 In France they make the bouillie de Bordeaux with copper sulfate for the vineayrd and it works especially when you do not have to spray after each rain.. Since the rain is over that should work f you can find it. or make it 1 Quote Link to comment Share on other sites More sharing options...

If it's white and sort of fluffy-fuzzy, it can be cochinilla rosada, which isn't a fungus, it's a type of spider mite, I think. It travels from one plant to another really easily and quickly.

cricket Posted November 1, 2020 Report Share Posted November 1, 2020 Agree with sm1mex - Laura at the garden center can help but needs to see infected leaves. Quote Link to comment Share on other sites More sharing options...

El Cartero Posted November 1, 2020 Report Share Posted November 1, 2020 Don’t know self help cures but my gardener referred to this as “la plaga”. He sprayed the plants every few months and the problem never came back. Is there a garden service Lakeside that will come and spray for you?

bmh Posted November 1, 2020 Report Share Posted November 1, 2020 Harry we had the same problem with the gardenia.. I assumed it was the heavy rain we had that drowned it but I do not know.. The gardner who is very good could not figure it out and we cut the gardenisa to sticks and I am waiting to see if it will take off again but it was a strange one.. Only one type of gardenia got afeected and the other plants did not so it may have been a different cause but the plant went very quickly from the blooming stage to yellow...

Harry I had noticed my Plumeria tree had a tan colored funk on the bottom sides of the leaves and were falling off so I got whats in the picture and its coming back so hopefully this will help you.

CHILLIN Posted November 1, 2020 Report Share Posted November 1, 2020 I think it was Lara that sold us a bottle of" plaga fin". It is broad spectrum and can also be used on entryways and windows. Also, some warm weather trees such as peaches try to shed their old coat for dormancy. Quote Link to comment Share on other sites More sharing options...
mudgirl Posted November 1, 2020 Report Share Posted November 1, 2020 Be aware that Mexicans refer to all insect, fungal, and other plant problems as "plaga". Quote Link to comment Share on other sites More sharing options...
