Brazilian raintree leaf yellowing

Posted by austin02 (My Page) on

I have a BRT and the leafs have started to turn yellow and fall off. My tree has droped leafs in the past, but now it is happening in greater numbers and the leafs are yellowing. Also i have noticed small sap droplets near the terminal ends of the branches. There is still a lot of new growth occuring so i think that i am feeding it and watering it enough. Is this normal and if not does anyone have a solution?

Maybe you're watering too often, especially if the soil is potting soil and not proper grit. Yellow leaves are a sign of too much water. What is your tree planted in? How much light and humidity does it get? And how often do you water and how do you do it?

Yellow leaves can be an indicator of too much/too little water, a high level of soluble salts in the soil (solution), a root-bound condition, an insect infestation, a nutritional deficiency/toxicity, high root temperatures, natural senescence, and a few other issues.

If the 'sap' droplets are just the slightest bit sticky, it COULD be guttation, but guttation is commonly manifest through leaf tips and margins, which leads me to believe you're probably dealing with an insect infestation - likely scale. Look on branches and possibly leaves for little bumps that come off when you scrape them with a toothpick or nail file. If you find none, look for evidence of mealybug - little white spots that look like mold or minute tufts of cotton.

If you rule out bugs as the issue, start on the list and eliminate the things you know it ISN'T. How long since the last repot? I'm asking about a repot - not a simple potting up.

Mine did this after repotting. I used N.E bonsai soil when i repotted. I noticed that that the tree condition was gradualy becomin poor. So I lifted the tree from the pot rinced out all soil. And then i made a soil mix 1 part bonsai soil/ 2 parts Miracle Grow potting mix. It has been growing Crazy ever since! If your seeing Sap on a rain tree. i would hit it with some Bonide systemic for house plants. That will take care of Any pests that might be a problem. Is your Tree indoor or outdoors?
