I have had this tree for almost 2 months. The day I bought it the leaves started to curl from the sides up forming a tube the length of the leaf. I have let it dry completly and watered it with no change. I repotted using 3 parts CHC 1 part each manure and peat . Still no change it has had miracid for fertlizer one time, the leaves have remained green and never been brittle and I have had no leaf loss. Any help is greatly needed as I am a new to citrus. Thanks in advance for any help I am trying to attach a photo.

Hi Bob, It is difficult to tell for sure, but from the picture, your tree looks like it does not get enough water. I do not worry much about leaves that curl, but otherwise look healthy with good color. - Millet

I have a clementine mandarin and it has the same but i read the leaves
curl up from too much water,so probably it can happen from either too
dry or too wet! I have been watering this tree every ten days in the summer
and its been ok.They wont un curl either.Have you had leaf drop?
From what i have studied,those chips hold a lot of water for 5-7 days no
problem.I didnt get on with the mix you had of manure,peat moss and
chips.I reckon the manure makes the mix too acidic and the peat moss
makes the airation suffer.
Miilet seems to like chc and coir,thats what i am trying now.My leaves also
went yellow from magnesium deficency and too soggy,i reckon.
If the leaves drop and leave the petiole(spelt wrong) the little stem attached
to the trunk = too much water.
Did you do the cation exchange business with the chips? see my posts.
My tree died with your mix and it hasnt worked for everyone. Millet has
helped me a lot with the problems i have had.cheers
when you water do it heavily but leave it a long time between irrigations depending on weather.

I didn't do the cation exchange but the plant went 1 month with no water in 75% temps. Then I watered and used miracid with no change. I talked to the man I got tree from he said his was doing the same in different soil. I am just at a loss as what to do. I have thought about adding some epson salt water but just don't want to water if to wet or withhold if to dry. I can take soil 2" deep an compress and it will hold form.

I have always tried to grow in full sun .Repotting and putting in full sun is
bad news.If you have just repotted,i suggest you keep them in the shade,
with some early morning sun,while the roots settle in.Thats what i have
done with my valencia orange.I mist them two or three times a day to keep
them cool and humid but not when in sun.My tree is going well now.After
3-4 weeks i started feeding with a fert npk 5-1-3 ratio as recomended
on this forum with trace elements.The trace elements are important
because they determine the quality of the fruit. I have citrus food i obtained
from the uk especially for this purpose.A summer food and a winter food
for citrus.
Im having success with a special container mix with grit in it,which improves
drainage. Be patient ,keep your tree somewhere it can cool off a bit,partial
shade,mist to keep cool and keep insects off,half strength feed once a
week with the 5-1-3 and drench the pot once a week and leave to dry
out.lift the pot up when dry and then when you have drenched to feel the
weight difference,so you know by feel when its time to water.
I have been reading a lot in books about this and this forum
helps you alot too,you will have to be patient for the next growth flush to
see some perky leaves!! the others will just look curly for a while.
I always put two teaspoons of epsom salts in with my soluble feed once a
week to help with magnesium,it helps the plant take up the nitrogen for
the green leaves.once every two months leave the hose to completly soak
the pot,so as to wash out all the salts and excretory products. Dont overdo the feeding,little and often will get you better results than a heavy
dose,this works on most plants .From what i have heard the chips need a
good soaking each time you water to hydrate properly.they stay wet for at least 5 days after that maybe a week.
All my trees are going well in partial shade,getting sun from 9 am to 1pm
they seem ok with that.good luck. there are many here who can offer you more experience than i have. I do have years of experience growing
tomatoes,beans,strawbs,bloody lethal chillies,runner beans,melons etc
cheers

Bob, if your tree's growing medium stays wet for an entire month at 75F temperatures, that is much to long. Like Laidback said, the aeration must be quite poor. The idea of the CHC's with a LITTLE peat or coir is to make a growing mix that holds a good quantity of water and at the same time a GOOD quanitity of air. Lowering the amount of CHC and adding the extra manure and peat made a 3:2 mixture (3 part CHC 2 parts filler) instead of the 4:1 mix. No matter what the type of growing mix you use, when a container stays wet for a month at a time, during warm weather, it is holding way to much water, and when a container holds to much water, it can not be holding enough air. Citrus is a plant that requires abundant moisture but CANNOT endure stagnant water, and at the same time, citrus roots are also highly sensitive to any deficiency of good aeration in the root zone. They require both. - Millet

Thanks for the help folks. As for staying wet for a month we had over 2" of rain last month so that did help. The soil its self drains very fast when I water no water stays on top at all it runs right thru. I checked and the moisture is fairly even top to bottom. Like I said the guy I got the tree from said his was doing the same thing I am just stumped. I watered today with added miracid and epson salt. I have around 15 other citrus in containers with no problems lots of blooms and some fruit. Thanks again for you time and know how.
