presuming they dont want to build their own Al's mix ... would they.. growing this TREE .. be better off with a cactus type bagged mix??? with its very high drainage???? .. or perhaps.. a 50/50 mix of their stuff and cactus mix???? the problem with high peat and trees is that it retain too much water ... and can get cold at night.. and cold wet soil leads to the suggested root problems ... and root problems usually end with root rots.. so jean was right both ways.. lol ... the bottom pic.. looks like the peat is completely dried out ... but that might be an optical illusion ... ergo ipso facto .. you need a better media ... BTW.. are they outside.. or indoors.. perhaps lack of proper light level isnt helping ... wait a minute ... you grew excessive water roots.. then potted it??? ... did you tent is at all.. until the water roots could adjust to the media???? .. if not.. add severe transplant shock to everything else .... one thing for sure.. the native range of avocado is not a peat bog.. though i couldnt find a map of such ... lol success is all about the growth tip ... if that continues to look good.. then who cares if it sheds all its leaves .. on some level you have to have faith in the tip.. and not worry about the old leaves ... otherwise.. you tend to try to love things to death ... ken ps: that little dish of media behind to the right looks dry.. always wet your media PRIOR to use .... peat is known to be near water repellant at times .. and you will never know.. if the middle of the pot has damp or dry media ...

Hi Rose, its quite possible too much water. Here near chicago its been warm and i notice lowest leaves are similar as your description. In my case its the water coming out of watering can and or hose hitting the lowest leaves each day sometimes resting on top of soil thats doing it for me.

I have the same thing happening this Year.I am sure it is Blackspot.I have been using a fungicide and it seems to be helping,at least it is getting any worse,and the Bush is looking really healthy apart from the already infected Leaves.

orchidrain, a picture would help for the yellowing leaves. It is normal for the tree to shed some leaves but not a lot. How old is your tree? is it full with leaves and fruit? where it is planted? We had a lot of wind in my area so I think I am one of the few with avocados this season, few friends had asked me about it because their tree did not fruit this year, the same variety like I have the Brogdon and they said it fruited last year fine. The only thing that I can think off is that mine is like in a sheltered spot and theirs are open to the wind so they lost the flowers, theirs are shedding the leaves also and we are in the same area with the same amount of heat and rain. I had a Lula avocado to sample, they can get big anywhere from 8-16 oz. The way that I know that my avocados are ready is when one or two start to get a black spot at the end, they are fully grown then and I can start picking them to ripen indoors. I usually harvest only what I need and leave the rest in the tree because they will last longer that way. My avocados are all different sizes in the same tree.... Silvia
