Yellow Veined Leaves - Improved Meyer Lemon
Comments (17)From the looks of your pics, the roots look healthy, and so does the new growth! I would be concerned about using fertilizer this time of year, since I am sure with the roots that bound, you are draining your pot of most nutrients everytime you water anyway...I would give a small dose at every watering. Too bad you do not have FP..It has every nutrient that your tree needs! I would also make sure it is getting Fe, by using a capful of vinegar in a gallon of water at every watering to unlock the nutrients, especially for the Fe that could be in the soil once fertilized..A good Ph makes the iron more mobile and for immediate use for your trees.. Give it a shot. A little fertilier and vinegar just might do the trick...Like I said, the new growth coming in looks great. A sign that you do not have root rot..You are also not loosing twigs or leaves at a rapid rate if at all. Hope it works out...See MoreMeyer Lemon with yellow-green pale leaves
Comments (3)redtitan23, The yellowing may simply be natural aging of the old leaves. I would however take a close look at the plant and see if it has any scale insects. I can't tell from the pictures you've posted, but in image 850 I think I can see a large scale insect (the tan oval near the leaf stem) and a small one on the lower left leaf which is partially visible. If you have one scale insect, you probably have many. If you see sticky clear drips of what initially looks like water drops on leaves, this is another sign of scale insects. If you have scale insects, you can reduce their numbers simply by rubbing them out with your finger, but that is a less than entirely effective method of control since they are often under leaves and on young branches. Meyermike has many postings that tell people what to do about them. I use two applications two weeks apart of a horticultural oil spray in the fall before I move the plants inside, and this year have not seen any scale or other typical pests on my plants....See MoreSome yellow meyer lemon tree leaves - new tree
Comments (17)Vegas, organic gardening is certainly not a crock and luckily, many hundreds of thousands of growers are willing to go the extra mile to produce organic fruits and vegetables. You should know, though, that you will have to study up on the nutritional requirements of citrus in general...and figure out how to provide them,organically, within the confines of a container. You are going to have to provide everything that your plant needs; citrus have some specific micro-nutrient requirements. I see nothing in the Jobe's product that disturbs me too much, though it does not have micro-nutrients, also called miner elements. Fish emulsion could assist in providing some key elements, when used in conjunction with your Jobe's. HOWEVER! It really isn't intended for container culture. There are no directions that I see on the label as to dose and frequency. Another aspect that is troublesome is that I can see how repeated use of this product would muddy up your potting mix....fill the so important pore spaces with fine particles. If you were looking for a product with a high Nitrogen analysis, you'll have to go with something other than your 'organic' products. Lots of container hobbyists resort to the commercial soluble fertilizers, while still using using organic methods for the rest of the plant care. I'm not saying that you should, but just be aware that you will have to keep up with the fert. in order to provide your citrus with what it needs. Another factor in the yellowing 'may' be the potting medium. Again, container culture is entirely different that growing in situ. Garden soil or compost added to a perfect good potting medium can result in a mucky, slow-to-drain mixture. Roots can function in that kind of environment, which is why we have learned to provide a potting mix that remains coarse textured and porous. I may not be the only one that would love to see you re-pot your plant entirely. I'd also like to warn you that moisture meters are notoriously inaccurate. Most of us have learned to rely on the most sophisticated digital equipment we have....our fingers. ;-)...See MoreSuddenly sad Meyer lemon -yellowing/dropping leaves
Comments (18)I very strongly doubt that your tree has a phosphorous deficiency. I have NEVER heard of a phosphorous deficiency in container citrus, when it is regularly fertilized with a NPK fertilizer. Phosphorous does not leach from a container, as does nitrogen and potassium. Nitrogen and potassium are both VERY water soluble and readily leach with every watering, but not phosphorus. All of the leaves that are turning yellow, and dropping are the older leaves on the tree. Your tree is withdrawing the nitrogen from the leaves (thus they are yellowing) to reuse in other part of the tree before discarding them. When a leaf no longer is capable of supplying its expected quota of energy to the tree, it is quickly discarded. There is no welfare program for citrus leaves. However, your tree is also under fed. If the tree's problem was other than aged leaves, you would be seeing yellow dropped leaves from the new leaves also. Also it is not wise to add this and that chemical in hopes of coming across a cure. First ascertain what the problem actually is then correct it. I'm sure it was also not helpful to the tree to let it remain in the same container and "soil" for 5 years. Fertilize the tree using a high nitrogen fertilizer. You can add vinegar if you wish, but there are much better ways to acidify. Organic acids such as vinegar, have an extremely short life....See Moregreenman28 NorCal 7b/8a
