Citrus Dieback - Need Advice

(1/3) > >>

This is a Sambucan Lemon- I planted it back in April. In general, I don't plant citrus because its been trouble for me in the past- Canker.  With that said, I planted this one for my husband. I have fertilized it ( Excalibur 8-3-9 2/ micronutrients) very lightly 3x since then. I waited 2 months before fertilizing.  I have been very frugal with watering ( it hasn't been dehydrated either)  and there isn't mulch-just some pine needles which naturally fell around the tree, which I pushed out away from the trunk.

The leaves look OK to me.  There is almost no new growth -the new looking growth was there when I planted the tree.

There is one healthy appearing lemon growing.

There is significant dieback - Is the acceptable for a young tree? If not, is there any way to stop/prevent it?

Nat it looks fine to me and I have had citrus drag their backsides and have some tip retreat when first planted.It can take months for there to be action.I would put mulch 12 inches from the trunk in a circle and through chicken dropping based organic fertlizer just outside that and wait for action.The leaves don;t look like there are any deficiencies showing.

Guanabanus:
New growth dieback on Citrus trees is a symptom of deficiency of Copper.

Thank you
What is the best way to correct this ?

Guanabanus:
Make sure your granular fertilizer contains copper.  "RFC Fruitlizer" does.  Spray with nutritional mixes containing copper.  Spray copper fungicides.

Avoid high amounts of nitrogen.  Too much nitrogen can cause copper deficiency.
