Do you fertilize the tree? Looks deficient in many nutrients especially magnesium. How long has this tree been planted near the brick wall? Did you dig a hole larger then the root ball, and did you add any foreign ingredients to the back fill, other then the soil that was removed when digging the hole?

Hi Silica, thank you for replying. I planted this tree a year ago right where it is. I did dig a big hole and added miracle grow soil for fruits and vegetables. I keep adding that soil regularly and water it regularly.

Unless the natural soil that you planted the tree in is incredibly free draining, you could have created a lake every time you water in the wole you dug and planted the tree in. When planting a citrus tree only the soil removed by digging the hole should be used as backfill. Does this tree get fertilized 3-4 times a year with a good fertilizer that includes all the trace minerals?

No i haven't used any fertilizers. Can you recommend something for this honey mandarin and also a large orange tree?

For young in ground trees, frequent fertilizer formulations used are 6-6-6 or 8-8-8 with trace minerals. A two year old tree should be fertilized 5 times a growing year. A three year old tree 4 times a year. Older citrus tree need fertilizing 3 times a year.

Thank you for the information. Is 6-6-6 and 8-8-8 names of fertilizers? What are trace minerals? Can you buy them with that name? Sorry for being such a novice:)

Most all blended fertilizers contain at least 3 ingredients shown as numbers on the bag, such as 6-6-6. These numbers stand for the three main ingredients, nitrogen, phosphorous and potassium. In the above example a 6-6-6- would be 6% Nitrogen, 6% Phosphorous, and 6% potassium. There are many fertilizer formulations available with all ranges nutrient percentages (numbers). Just don't get a blend to strong for a young tree like yours. Trace minerals are all the minor elements such as iron, magnesium, zinc etc. Tell the nursery you want to fertilize a citrus tree and you should be OK. At any rate what ever your get will be much better for the trees then not feeding them at all. The best to you and your trees.

Thank you so much for the detail information. I will get these today and start fertilizing them. One last question..do you know how much quantity I should use each time - 5 times a year?once again, thanks a lot for your help.

Just follow the directions on the fertilizer bag. Each formulation will be different. Example 6-6-6 would approximately be 1.5-lbs. /application. 8-8-8 which is stronger would be approximately 1-lb./application/ Whatever fertilizer you purchase just follow the recommended application rate printed on the bag. Spread the fertilizer evenly around the tree to about 1-ft beyond the drip line. Stay about 6 inches away from the trunk.

Thank you for all your help

I second the recommendation for Foliage Pro. You can find it at some nurseries, and it's easy to purchase from Amazon. It mixes with water and would give quicker results. And is highly thought of around these parts.
