Is anybody able to assist me with my lemon tree. I know just about nothing regarding fruit trees so even basic suggestions will do.
As from the attached photo, my lemon tree just isn't right!!
It's been in this spot for about two years, so I don't think it's a soil type issue, and it receives plenty of sun throughout the day (although in shade for this photo Hilarious! )
But it is very yellow and bare... and not the yellow I want!! Before I planted it I did the soil draining test; and water drained fairly quickly, and considering the rain we've had, the soil isn't that damp so I don't believe its water logged. I've also been giving it RICHGRO Fruit & Citrus fertiliser and Seasol (according to package directions).
There isn't any sign of fungus and it still flowers and fruits (first year fruiting). It did start yellowing before fruit appeared though...
I have two citrus trees nearby that although are growing slower than this fella, are healthy looking Hurray!
I was also told to trim off the lower branches to make a trunk, is that true?
Thanks in advance!

@Zachari, I'm sorry this hasn't gotten an answer. I have a lime tree about the same size and age, and it sometimes looks the same. I really don't know what the problem is, but it continues to produce good fruit. I think it must have a nutritional deficiency of some sort. I do feed it with granular citrus food when it looks bad and then it greens up for a time. Then, you guessed it, it goes yellow again so my guess is it needs more regular feeding. I've also carefully checked for insects or other problems, and have seen nothing.

I'm pretty sure the yellow color of the leaves is due to chlorosis, caused by iron deficiency, likely due to the pH of your soil being too high (too alkaline). I had this same problem with blueberry plants and resolved it by amending the soil with a lot of sphagnum peat and compost, and mixing in soil sulfur and greensand. And using an acid-lovers fertilizer, such as "Miracid." (I'm not familiar with RichGro, and it's possible that it also helps maintain the lower soil pH.)

Sandy, that sounds right, because my Arizona soil and water are both alkaline. I'll try to acidify it a bit.

I agree with the possible iron deficiency. Mine are in pots and I give them chelated iron in water every couple of months. I would assume that no weedkiller is used on the surrounding lawn either?

Zach : I agree
And will also add. You'll have a happier healthier tree if you remove grass. At least two feet beyond dripline of tree. Lemons are shallow rooted. 6 to 8 inches. Grass is stealing nutrients. Grass, i bet, could be your whole problem. Do other trees the same. Do apply fertilizer at dripline.
I live in citrus country. Our water is alkaline.

As far as pruning goes.
Prune to whatever shape your heart desirers. 😁😁😁
