Comments (3)I'm sorry. Your image link doesn't work. But, based on your description, it sounds to me like the fruit are infested with the larvae of the plum curculio, which is a very common and major pest of fruit. They cause what you describe - misshapen fruit, which in the case of stone fruits can ooze sap from the wound where the female laid the egg. Cut some open and see if there are white grubs inside eating the fruit and the forming seed. If it is the curculio, check out the numerous threads on here about controlling them. Sevin won't work at all, the PC is basically immune to it. Imidan is the chemical of choice, but the timing of the sprays is very, very precise....See MoreWhat is wrong with this Lemon Tree? (PICS)
Comments (6)Actually, I'm thinking this is manganese deficiency, and not magnesium. Here in California for us, it's manganese, then to a much lesser extent, iron. As our weather warms up, this will dissipate. Use a good citrus fertilizer that has micronutrients (Gro Power Citrus & Avocado Food, which is a properly balanced fertilizer with correct micronutrients plus humic acid). And, you can also use either a foliar micronutrient spray, such as Grow More Citrus Growers Blend or a granular product such as FST. (I would steer away from Ironite - too much iron for our area, if you're in S. Calif.) If it is salt burn, that will go away if the tree is in the ground. If it's in a larger pot, then flushing the pot with water as mandarin1 has mentioned is the remedy. And, usually, most folks who have water softeners only have that attached to their inside water, and not their outside water here in California for a myriad of reasons - cost to "soften" outdoor water, plus the added and unwanted salts in your yard. It is a rare thing to have your softener attached to all your water supply. Patty S....See MoreWhat is wrong with my Improved Meyer Lemon Tree
Comments (5)Well, I see a few things that might be causing this. It looks like you've got a situation where you have a LOT of grass competing with both water and nutrients . You really do need to create a much large cleared area from underneath your little trees. Grass is a huge nitrogen hog. It will simply gobble up all that nice fertilizer you're putting down for your citrus. Not familiar with that particular fertilizer, but you'll want a fertilizer formulated for citrus, that is higher in nitrogen and also contains a good amount of micronutrients as well as your NPK macronutrients. And if your trees are being sprinkled by your lawn sprinklers, this is NOT good for the trees. This actually can eventually kill a small young tree. They don't like their trunks sprinkled. You'll want to put your trees on a drip system, and give them a long, deep drink one or twice a week (depending up on how hot it gets.) Doesn't look like sunburn, and yes, young citrus trees can get sunburned if you live in very hot, dry, sunny areas (like AZ, interior S. California). I agree with John's recommentations, fertilize at least 3 times a year - I fertilize 4 times a year - February through September/October. And, I use a foliar fertilizer especially if we've had a cold, wet winter and spring, which for me tends to make micronutrients unavailable since my soil is mostly DG. Grow More Citrus Growers Blend is a great product, and can be applied both to the roots or as a foliar spray. Spray in the evening. Patty S....See MoreWhat's Wrong with These Lemon Leaves?
Comments (3)You may have spider mites they are nearly impossible to see without a glass; I would suggest a good washing with the hose at least once per week. Your new growth looks quite good, so I wouldn't stress much, but a regular bath for the tree goes a long way to keeping it healthy....See Morejohnmerr
