Chlorosis and Carambola

CarambolaSeptember 14, 2011

I am new and this is my first post, so please bear with me.

Earlier this April I managed to propagate some Carambola trees from seed. I have twelve of them and they are growing in 1 gallon containers filled with Miracle-Gro� Cactus, Palm and Citrus Soil. For the last two or three months they have not been growing very much, most are suffering from some form of chlorosis. What I can't seem to figure out, is the cause of the chlorosis. I know that it is due to some deficiency in either Iron, Zinc, Manganese, or Magnesium, possibly a combination of these. I've treated them with a slow release fertilizer (Miracle-Gro� Shake 'n Feed� Plus Moisture Control� All Purpose Continuous Release Plant Food) in the hopes that it might give them some of the micronutrients they are lacking. It has only been a week, but it doesn't seem to be having much of an effect. I'm considering getting something that has more Iron and Magnesium, possibly a foliar.

Here are some photos of my plants;

Any suggestions are welcome and would be much appreciated.

Thank you

Hi and Welcome!

I've never seen chlorosis like that, the leaves are almost white. I also suspect you are overfeeding from pictures of the burnt leaf edges. I've grown carambola, was too lazy to feed anything...and they seemed to do fine. For young seedlings, I recommend being on the conservative side w/fertilizers.

I noticed the same problem with my small carambola plants (a few years ago) when I watered with tap-water. I started using rainwater instead and the problem stopped.

Just go and get a good micro nutrient foliar fertilizer from a nearby hydryponics shop.

Carambola hates high ph soil conditions. What sort of potting soil are you using? They love peat moss based mix.
