Hello Forum!

I noticed plant bugs-aphids-on both of my trees. They are usually all over the leaves. When I first noticed them, the population with small;however, the rate increased rapidly. I decided to buy something organic to avoid harming the trees. I purchased "Safer Brand 5110 Insect Killing Soap."I applied it using the directions on the bottle. Today I checked that both trees look unhealthy. The leaves harden. Some turned black and were hanging down. Others turned into a lighter green. I removed most of the dead leaves.
However, another reason could be that I underwater. I did not water the trees for 6 days. The temperature dropped to mid 50s. I check the soil and I still sense moisture. I watered them today to be safe.
Here are some pictures:

Your feedback is gladly appreciated,
Nick

Leaf death is certainly possibly due to underwatering. Insufficient water is a typical new-to-bonsai problem and comes down to misinformation in the internet.

Carmona/Fukien Tea are some of the hardest trees to keep happy, I've had several and will never buy another one, ever.

Edit: I just re-read your post and you said it was still moist.

I've not use this soap , only the spray on stuff in a can and that works.

Mid-50's temps can be another cause...

Do not water if the soil is still moist. You may have had some root death during the period of non-watering and now you are technically over-watering which is counter productive to replace those roots which have perished. Hopefully its not too late. But do your best to eliminate all stressors: not enough water, too much water, too much heat, too much cold, keep it in a semi shady area not direct sun unless its really cool where you are, do not fertilize right now.

Thank you, are you sure it was because of under watering. My brush cherry is totally fine and I did not water it for 6 days too. I believe the spray caused it. I placed it in a shady area. Should I remove the dead leaves hanging on the tree?

I have no idea what caused it. I just provided you with general care and aftercare instructions. Add misting leaves to the list of care instructions

Fukien tea is very sensitive to insecticides, chemicals on the whole.

They require lots of sunlight /light to stay very healthy.

Look up this guy on Google, Carl Rosner, he lives in New Jersey and has tons of experience growing Fukien teas indoors.
He is an Artist and can be contacted through his website.

If he likes you, he will also send you seed and you can simply try again, just in case you lose your shrubs.
Later.

My aunt gave me a Fukien tea. I had heard that it can be left outside and only brought inside if temps go below freezing. Is that true?

It would be safer if you did not leave it out past 55 deg.F, until you know the limits of how you will get through winter.

Next year in late spring strike a cutting and let it stay outdoors for the year, see how it handles the temperature.

You should know what to do after that.
Good Day

Fukien (my experience) are difficult to keep bug free. I use neam oil (infrequently) and during the winter (when mine is indoors) I spray it down once a week with a hard spray of water. Any new insecticide should be tested on one small unimportant branch first to make sure it isn't harmful.
Don't let it dry out. Keep it in strong light. Remove the dead leaves. Give it some time to recoup.

I live in New Orleans and have pest free plants for the past 3-5 years.
This is attributed to not using chemical pesticides.
As a result, natural bug predators, such as green lizards and tree frogs, are abundant.
Thanks to them I've not had a pest problem since they showed up.
When I water the little tree frogs hop up on the rim of the pot till I'm done.

Hi Nick, I hope your trees made it, somehow I doubt it though. Unfortunately I have seen my own Fukien Teas in that shape and all of them died. I am with Jerry - I will not buy another one ever. I have successfully been growing Ficus (Nerifolia, Benjamina, Retusa), Chinese Elm, Rosemary, English Ivy, Grewia and Chinese Hackberry indoors under grow lights in the Winter and outside in the Summer... the only plants that did not survive were Fukien Teas. I don't know what it is about them, I think the misleading fact is that they are so easily available as a bonsai especially at box stores (Home Depot etc.) so that would make them a potentially perfect beginner tree and they all look good for a while. After that every single one of mine (I think I've tried 3 or 4) died a slow death for no apparent reason at all. Like I said, all the plants listed above were in identical conditions and thrived... When they got to the point of loosing leaves I've tried everything and it did not help at all, seems once they got weak there was no return from there, at least for me.
