Help for 50 year old backyard lemon tree?
« on: November 04, 2021, 01:12:09 AM »
This tree has been strong and prolific for as long as I can remember, but this year it is looking droopy and possibly in trouble.  One family member has hypothesized that it is approaching the end of its life. :'(  I've read online that 50 years is average, but that some lemon trees can grow to be as old as 100.

There have been no recent changes to the conditions under which the tree has thrived over the decades, except...

I did plant a tangerine tree about 20 feet away during the early months of Covid (Mar 2020). That tree is yellowing a bit (probably too much water, though I'm also now giving it citrus tree food), but I don't think I introduced a disease or anything like that. (I certainly hope not.)

I'd be so grateful for feedback and recommendations.  Pics below...

Underfertilized and possibly overwatered.

Definitely under fertilized.  Fertilize with a fertilizer high in nitrogen and potassium.

Thank you, everyone!  (And apologies for the delay in replying.)

sc4001992:  I will get on this immediately, thank you. (Regarding "getting old"-- we asked a landscape architect to look at the tree a couple days ago, and he said basically the same thing.  But obviously I'm still going to deal with the dead stuff per your recommendation.)

matt_citrus and Millet:  The watering has not changed over the decades... same sprinkler system, pointing in exactly the same direction, going off with the same frequency.  So with that piece remaining constant, I'm reluctant to roll the dice with big changes.  But we are definitely fertilizing now (which hadn't been done since the tree's earliest years). 

The citrus tree food I bought from the nursery has recommendations for monthly and twice-a-year maintenance. Your feedback makes me think the maintenance protocol would be too conservative. Maybe I'll start monthly and move to quarterly.

In any case, I will be cutting off the dead stuff immediately.  It seems we have been taking this tree for granted!

Many thanks again for the replies, everyone!

If you are concerned about making large changes to the whole tree, you could try a foliar spray of fertilizer to only a specific section of the tree and monitor it over time.  I suspect you will see it green up compared to the untreated areas.  If that is the case, it is good evidence that your tree needs overall more fertilizer (delivered via roots)

This is a great idea. Thank you!

Not a pro in this, but could this tree use some rejuvenation trimming to produce new young branches? I also see alot of dead branches( small) in there, its becomed entangled and this is preventing air flow ,thus the chance of desease increases. I am not an expert in citrus ,but that's rather a generall tree care thing.
U can use the trimmed parts to start new plants also!
