Common manganese deficiency on fresh new growth. More important why is there trifoliate leaves showing towards the lower portion of the tree? Are they from the rootstock, if so they need to be removed.

Silica, I am seeing some of this as well. How would you recommend we add manganese?

Those leaves at the bottom are certainly rootstock. I'd remove them like Silica said.

Joel Natividad it is not a magnesium deficiency. However, you can add Epsom salts if you have not added any in some time. Manganese deficiencies show up on NEWEST leaves with green veins that have green border areas to the side of the veins on an otherwise yellowish appearing leaf. A zinc deficiency has much the same pattern as a manganese deficiency, except the zinc deficient leaf becomes quite small in size. Manganese deficient leaves remain the normal size.

kandimilo, you can treat your leaves with a water soluble manganese such manganese nitrate or sulfate, or you can do nothing. Check the fertilizer you are using to insure that it contains manganese as one of the trace minerals. If so I would do nothing, and your new flush leaves will become normal green as they mature. A manganese deficiency usually only shows up with a fast growing flush of leaves. After the flush growth stops and begins to mature, the manganese catches up.

Epsom salt is Magnesium Sulfate (MgSO4) and I would not advise adding it to potted trees unless you see a clear Magnesium deficiency. Having said that I add a little MgSO4 to my garden Meyers every time I put it on my roses. For in ground trees a little extra Mg never hurts; and Meyers are heavy feeders of Mg, especially when they are producing a lot of fruit. Manganese "deficiency" is common when soils or weather are cool or the pH of the soil or water is a bit high.

Epsom salt for roses? John, tell me more! My soil and weather run cool, so I can see manganese being a deficiency.

Silica, I alternate between AS, Peter's and Citrus-tone. I'll see if either of the last two might have either of the trace minerals, thanks!

Thanks Silica. I use foliage pro fertilizer, does it have enough manganese?

Ok, my Jack's professional water soluble (25-5-15) does list both magnesium and manganese as trace nutrients, but i haven't used that in a few weeks, since I've been using the AS and Citrus-Tone. I think I'll give the trees one last feeding of Jack's before it gets any cooler.

Jocel, you should be OK with FP
