Lemon, check for mites..look for fine webbing..I'm not saying this is the problem, but mites leave foliage looking mottled. Toni

I cant find any webbing. I have had a lot of spiders on the plants, just big ones when I put them outside... could they be part of the problem? I just find it weird, its beside all my other trees, but its the only one with the problem

it could be high ph in soil, or iron deficiency. are they really yellow but you can see the green veins within the leaves?

nope, leaves are pure dark green. just like a normal leaf... a tad dry and not at all glossy like a lot of my others. I dont know if this is normal for the lisbon. I cant remember if the leaves were more glossy when I got it or not. the leaves are just looking really really dull and dry... but not brittle by any means

In all honesty I don't feel that humidity plays a large role in things unless maybe there is an abrupt change in that humidity. And of course if the air is very dry then you may have increased water loss and thus may need to water more frequently, but my potted trees are all grown in a very dry climate and they do fine ( well, at least in relation to humidity :) It sounds a bit like a water uptake issue in some capacity--roots are not working like they should to bring water up to the leaves, or there is not enough water avaliable to them for uptake. I find that citrus do one of two things when they do not get enough water up to the leaves (Ha! believe me I see it all the time, with way I torture my poor trees :)--they'll wilt/roll and leaves start to look a bit dry, or they'll just drop some leaves out of the blue. No warning, the leaves just come right off. Plus the dried out leaves will sometimes come off after I do water anyway...but that's in my limited experience of course and I am sure variable (that's the backdoor you love, if you're reading this Al...)

So, with that said, I will usually react to something like this by a very liberal watering, making sure that the entire rootball gets saturated. I get so paranoid about overwatering that I tend to ignore the other problem of underwatering. If I cannot *exclude* lack of moisture as the problem, it gets watered well. If instead you were saying the trees had been getting a daily heavy dousing or whatnot, then that prolly wouldn't help (well, unless you are not sure the rootball was actually getting wet--compaction will sometimes keep water out as well as hold too much water, but then that gets into other issues...) Plus, I have this attitude: If I have induced some root rot and that is why the roots aren't working, then is just one more liberal watering really gonna make a huge difference anyway? It's already wet and without enough air as it is. Of course, I am assuming that you are using a soil that drains well....

The last thing that stands out to me is that you are bringing the tree in and out periodically. Maybe this is the source of problems?

Also not all citrus leaves are extremely glossy all the time. I think is has a lot to do with age of leaf (not necesarily decline due to senescence but just being fully mature) and cultivar. I don't find Lisbons to produce very glossy mature leaves but pummelos seem to like to show off a bit longer :)

lemon_dreams, I think we have a mutual friend. Do you know fozzybeth? She'll prolly wanna hear about this if you do know her.

HTH.

yep, we have a friend in common :) I was just writing her an email. :)

I think it is somewhat do to lack of water. I took a few trees out of pots today and noticed even though the top was still damp, the bottom wasn't. (isn't that normally the other way around??) What I think it was, I had 2 of my trees on top of my barbeque.. black.. hot sun.. dried up from the bottom up... rather than top down. I've given them all a great soaking today. I'm sure all will be fine.

thanks for the replies. Ithought I had looked up, researched so much... but its SO different once you have your trees in front of you... having problems. Heh... didn't realise how much these trees can stress a person out!

Glad it's under control :) I'll check in with fozzybeth--she had nice things to say about you.

Rick, who is Fizzybeth? LOL..Does she post here? Toni

If you don't already know her Toni then you're missing out.

Rick, does she go by that name, and why am I missing out? Toni

I dont know her name on here, but shes amazing. Goes well above and beyond in helping ppl. I'm sure she'll read this... heh.. I keep thanking her for things she has helped me with. and may be helping again soon :) *BIG GRIN*

Its amazing some of the ppl you can meet on these groups!

Lemon, it's nice there are helpful ppl here on GW. And it's enjoyable talking about our citrus..especially those of us who understand how nice it is to grow something we love..I'm one of 5 children and the only person who likes plants. My one brother has 3. My other brother as 2 NO citrus..My father hated the smell of flowers..before he died, he told our mother he didn't want flowers and to put in the notices. My mother was not interested in in or outside plants. So, I don't know where my love for plants come from..Toni

My parents grew up on farms... minnesota farm families back in the 30's. you grew your own food or starved. 1 or 10 kids or 1 of 8. grazy the ammount of kids ppl had. then... my parents had 5 kids... also on a farm in minnesota, then moved to bc where I came alone several years later. Its always been flowers, gardens, plants for as long as I could remember. My dad did a lot of mixed fruit grafting and created a couple interesting varieties.

out og my 5 other siblings, Im the only one thats so into plants, gardening... sure they have the typical veggie gardens and the occasional house plant.. but.. I'm definatly the plant/tree crazed kid. funny thing is... I'm the one that loves the gardening and such the most... but I'm also the one wit the LEAST room for it. I rent my house. NO garden space. everything in containers from my tomatos, peppers, cukes, squash.... and of course citrus. My next goal is to try and find dwarf varieties of other fruit trees.. that may grow in containers. apples/peaches/plums/.... and whatever else. Just crazed. I just love the whole thing of growing my own fruit/food.

Fozzybeth is one of my all time favs here, too.

Al

great to know so many other ppl on the site know and like her so much!

Hard to not like her, lots of knowledge, happy and goes out of her way to help others.. like me.. really a total stranger... still find it crazy that there are great ppl still out there.

We could almost consider Fozzy_Beth our maine cat on the forums? Ya think? ;o)
