I'll start off with the good news. I finally got my meyer lemon to flower, well, it has about 6 buds currently growing on it which will turn into flowers.

But it also has yellowing veins in it. I know that is a sign of nitrogen defficency, but why is it that my washington navel is fine and has had the same amount of care for everythiong? Could my Meyer need more nitrogen more often than the orange tree? Where could I buy the minerals needed to give my plants bvecause I don't know if my fertilizer has them now that I think about it (it doesn't list them at least) and which minerals should I buy? I'm also just getting ready to pull my plants in this week as it is getting cold and I have been giving them less light for about 3 weeks now.

BTW, to end on a good note, my orange tree has about 3 fruits left on it, 2 pretty good size I think. Hopefully they make it.

Thats about it, Ill stop typing now, I think I messed somthing up at football, the screen wont stop shaking

There is a slow relaese fertilizer --Dynamite-- that has trace minerals and is formulated with a ratio that is close to 5-1-3 recommended for citrus. Osmocote also has one with trace minerals, but I have never seen it down here in FL.

If you want to add trace elements separately, I bought a 5# bag of Essential Trace Elements at an Ace hardware that has the necessary trace elements, and there is also a product called STEM (Soluble Trace Element Mix), but I believe it is only sold in 25# bags.

Hello,
yellow veins can also be a symptome of low root activity and inherent low nutrient uptake.
Also a root damage may lead to less nutrient uptake and yellow veins...

So not only nitrogen deficiency can show up in yellow veins, even some root problems can come up as yellow vein symptomes...
Just something to keep in mind, I think.

Ok, thanks for the info guys! I'll do a little experimenting I think. Ill probably buy some fertilizer that for sure has the nutrients in it and see how that goes. I do know though that both of my trees had root damage when I first got them because I let the roots cook on my deck from it getting wayy too hot.

I have two 5 year old Eureka Lemons that are growing in 10" pots that I have been fertilizing with Bandini Citrus Food w/ 2% Iron. I have been using it for about a year and it works great! I have mentioned this in this forum before to a great deal of laughter. It works for me!! You do have to watch out not to over feritilize because it is a time release fertilizer.

Sweet, I hope it really is only nitrogen and other minerals and this problem get fixed soon!

It all depends which leaves have yellow veins to determine if your tree is actually deficient in nitrogen. Nitrogen is mobile within a plant. Therefore, a nitrogen deficiency shows up in the OLDER leaves, with the new leaves still retaining green. If all the leaves that are yellowing are lower older leaves at the bottom of the tree, it is also very possible that they are just old leaves that have reached 18-24 months of age, and have lived out their life and are now being dropped from the tree. A citrus leaf has a life span of approximately 18 - 24 months. When a citrus leaf uses more energy then the leaf produces for the tree, they are quickly dropped. There is no welfare plan in a citrus tree. At this time of the year many citrus trees are discarding older leaves. Almost every fertilizer sold contains nitrogen, with few exceptions. - Millet

if anyone has bought this online "Dynamite" or something simalar could you please post a link... having a hard time finding what i need...
also if someone has some if you could just maybe post a pic that would be great...
thats some much for the help

Here is a link to Park Seed company as a source. There are several different formulas -- this one is 18-6-8 with trace minerals.

here is another link with pictures of another formula.

thank you!

Dynamite is the same formulation type fertilizer as Osmocote. Osmocote is the standard of the industry, when it comes to slow release fertilizers. You should be able to locate Osmocote slow release fertilizer at almost any nursery, or garden center. - Millet

Millet--Not so around here-- at least for the one with trace minerals. I have looked at all of the big box stores and all I find around here is the Osmocote without minerals.

Because Osmocote is mainly marketed to the commercial nursery trade, trace minerals are generally not included. Commercially, nurseries add trace minerals separately in the form of STEM. The reason is because different amounts of trace minerals are required depending on the intended use of the growth medium . However, Osmocote 17-7-12 (the formulation I use) is a formulation that contains trace minerals. Dynamite might also be a good slow release fertilizer to use, I don't know as I have never seen nor used it. What chemical form is the NPK and trace minerals, and what is the method regulating nutrient release (heat or water)?- Millet

I will look at the formulation ingredients the next time I go to HD. I am still using the bottle of Osmocote without trace minerals and adding them separately. I don't know the release mechanism, but it is even slower than Osmocote, some listed as 6 month and some listed as good for 9 months.

Of course, the slower the release the less amount of nutrients are available to the plant at any given time. As citrus are heavy feeders one would want to be sure to supply enough nutrients to the tree to maintain optimal growth. If Dynamite is sold at HD, I can also look the next time I'm at the store. However, when I purchase Osmocote I buy it in 50-lb. bags, to obtain a wholesale growers price.- Millet
