Sick Brazilian Rain Tree and Ficus salicifolia
« on: November 25, 2013, 10:15 PM »
Hey Forum,

Over the past few weeks I noticed how both trees got sick. The leaves on the ficus turned bright yellow and fell off (noticeable in pictures). The leaves on the Brazilian rain tree are just hanging down. The temperature in NYC significantly dropped (30-40s). I placed both of them on a granite window sill. I water them about 1-2 times a week. I decided to remove both trees from the granite and place them away from the window in a shady area because I fear that cold granite may bother them. Any advice?
?

Thanks,
Nick

How much light?  What is the temp where they are?  Are you checking if they need water every day.  Needs change indoors.

Room temperature, but the temperature near the window was definitely lower. Not sure what the exact temperature was. I did check the soil. I read that bright green/yellow leaves could be either over watering or under watering. I placed them away from the window in a shady area now.

Brazilian raintree and the Salicifolia are trees that need moisture. I recently moved to calgary, canada. I have a tsalicifolia send to me from the tropics. It was lost and somehow survived.  I have the salicifolia next to a window and it started sprouting now. I have a pray bottle a mist the trunk once a day. the soil I water everyday. I use course river sand, lava rock and pumice in my mix. To this tree I added a little of humus. So far it has improved a lot. Check your soil, is it too compact, is it loose, does it retain lots of water?

Engineer....room temperature?
My daughter heats with wood her home is usually at or near 70.
We do not, our home is at 59 at night and in the very low 60's during the day.
I think my daughters home would work for your trees....not mine.
In addition, those marble window sills probably conduct the cold from outside...
Just my two cents

Both trees need full sun and a good drainage.  The brazilian look that is  in the  much shadow.  The brazilian grow better in with porous soil, much water,and full sun.  The ficus hold temperature of 5c grade (41f), i have mine planted only in volcanic soil and coarse river sand, with out organic soil.

Thank you all!

I agree jay, the pots do get cold. I'm being more observant with checking the moisture. I placed them back on the window sill. I thought shade would be good for trees under stress or when they look ill. I noticed that the leaves on the ficus are sticky. In addition there are black circular spots on the branches and leaves. I will show pictures. The leaves on the rain tree are dry and they did not rise up recently. I am thinking of purchasing a moister meter. What do you guys think?

Scale?

This is definitely an infestation.

The raintree is likely affected as well.

Good luck. Seems close to ..... I can't say it.

Someone else should tell you exactly what to do.

That looks like Scale insect and you need to get rid of them. An insect control from a garden store should do. Try not to get too much on the soil as the tree looks weak. You might want to cover the soil and wait for the application to dry. The Brazilian is a more much stronger tree. Even if it is next to the Ficus is it probably insect free. Anyway a cloe look on the brazilian won't hurt.

Engineer.... Moving trees inside when the weather gets cold is a VERY BIG change for them. The humidity is way low, the light level is lower and the spectrum of light isn't as broad.
It is important to not yoyo the trees. You need to know what they need and stay with it. This is more of the patience thing.
They need to adjust.....
I'm sure someone with greater knowledge will step in and give some thoughts......
If these are scale, they can be removed by hand....slow process for sure. But before you use chemicals make sure what you are dealing with
Good luck
And happy holiday
Jay

Happy Thanksgiving Guys!

I filled up my water pressure sprayer with water and bit of safer and sprayed down the tree. A bit later on I worked my way around the tree by examining the branches and leaves to remove everything in sight.

As a note for nextyear.

I had one ficus outdoors. I chopped it hard and defoliated 96% upon bringing it in. An inch under 2 - 4ft. Plant bulbs for 16hrs, it is still growing the best. I think the pruning keeps them from knowing to sulk.

Of course this year your trees likely couldn't be pruned as such due to the pests.

I don't use chemicals so less leaves makes it easier to remove pests,(mostly mites) upon bringing it in.

I keep an army of jumping spiders(canopy), see photo, and small centipedes(soil), to combat pests. Nary a pest can avoid these voracious predators!

Hi I live in north Jersey and have lost of rain trees one of my favorites. I found out two things about my tropical. First I give them a shower every week. I wash them head to pot this seemed to help greatly. 2nd my rain trees seam to drop there leaves  (not all of them but lots) and bud out again. I had a good friend that had two big rain trees and he told me that is the best time to repot, he also had a green house. I also feed my tropical very lightly in the winter. Hope this helps Peter
