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 MoreDiagnose yellow leaves on lemon tree?
Comments (7)I don't know if this is the case with your trees, but I've had that happen to a couple of my Meyer lemons when I've been lax about fertilizing. They tend to need fertilizing at about twice the frequency as my other citrus. Maybe your Eureka also needs a bit more food than the other citrus. Also, I've not found the yellow leaves to really green up again, at least not much. Usually what happens when they get to that point is they tend to drop the yellow leaves over time and replace them with new leaves. If I've been good about fertilizing, the new ones will be nice and green. So I think if you keep up the better care, the next flush of leaves should be much greener.

Comments (3)Agreed. Looks like micronutrients are in order, Trojan. This is a pretty common sight here in our neck of the woods (Orange County, San Diego County, Calif.) due to our long, chilly and wet winter and spring. Many of my citrus looked this way. I spoke with Vince Lazaneo, the Home Horticultural Advisor for the San Diego Master Gardeners about a couple of my citrus, and he also suspected micronutrient deficiency. I use Grow More Citrus Growers Blend, which is an excellent product that provides micronutrients in the correct percentages and concentrations for citrus. I have applied it twice, now to my affected citrus. First time as a foliar spray, and then about 4 weeks later, to the soil, diluted in 2 gallons of water, and then followed up with an additional 2 gallons of acidified water (I use plain old white vinegar, and acidify to 4.5-5.0, use a pH meter, they can be found at any better garden center, and they're cheap insurane). The acidified water will help the tree take up and absorb the micronutrients. And, for your new trees, you will want to fertilize twice a month during the growing season (for us that's about April through November) with a good citrus fertilizer that has micronutrients. Vigoro Citrus & Avocado fertilizer with micronutrients is decent. You really want to find one with a high sulfur micronutrient content, as this will help to acidify our somewhat alkaline soils. You can also use soil sulfur once or twice a year as a top dressing to help out our pH issue. If we we a lot of cold weather, and a lot of rain, that, along with our somewhat alkaline soils will cause a locking out of micronutrients, and your citrus will look like what you're seeing right now. And, as far as amending your soil - I don't recommend that. You're going to create this yummy "hole" that your citrus roots are not going to want to leave. You're better off just digging a hole twice as large as your root ball and backfilling with your native soil. Loosen up the soil, and make sure you don't create slick sides in the hole from your shovel. Fill that hole up with water. Wait 24 hours. If the hole has not drained by then, you have a drainage issue, and in that case, you WILL want to amend with some gypsum. Otherwise, you're good to plant. Backfill with native soil, taking care to water in well to remove any air pockets. Keep the rootball at soil level (unless you're in clay, and then elevate the top of the rootball a few inches). Create a nice large well that extends to at least the drip line (tree canopy). You'll want to extend this well as your canopy grows. Set your drips to drip in the drip line of your well. Then, fill with about 1 to 2" of worm castings, another layer of compost, then top with bark mulch. Be sure to keep all clear of the trunk by a few inches all the way around. Water in well. Then, sprinkle your fertilizer around the well ring at the drip line, and water than in. Paint your trunk and exposed branches with indoor water soluble flat latex house paint diluted in half with water to protect the trunk and branches from sunscald. That's how to plant a fruit tree here in S. California :-) Deep water during the hot summer months 2 times a week, then cut back to once a week in the winter, or no watering at all if we're getting rains. Top dress with soil sulfur once or twice a year. I usually will top dress at the beginning of the growing season in April, when I start fertilizing, and then again, around June or so, when our weather starts to heat up. Remember, NEVER fertilize or apply sulfur to dry trees. Okay, probably more than you wanted to know, but certainly I hope will help your little kumquat green up :-) Patty S.

Comments (0)Hi guys, I recently purchased a meyer lemon tree and it was doing well until this week when the leaves began to turn yellow. The yellowing appeared punched out and appears more prominent on the sides. I am not sure what can cause this. My soil humidity level is ok, I'm using parrot which helps to prevent over watering. I've attached few photos. Any help is highly appreciated. I really don't want this plant to die. Thank you!...See MoreL Evans
