any ideas my red maple which has been blooming for the last 4 months..all the leaves ahve curled up and died not sure if this is becasue of the
weather change or is nayone else has had this issue? thre no bugs on her the branches are still very healthy just the leaves have all died.

On Atropurperum the wind quickly dries them out. Keep it out of the wind and feed it a little and it should come back. It is good to post your habits with the tree so we have an better idea as to advice.

not to be rude habits?? you mean whether she is happy or sad sort of thing lol

Hi Sahara, is it possible for a picture please?
I am sure Bodhi is correct!
Cheers, Dario.

Habits as in how often you water and fertilise, where you keep the tree, type of mix, when it was repotted last etc etc. These can have an impact on the tree - for instance if you had recently repotted and root pruned (now is the wrong time of year)

Hmmm, Bhodi is correct but also I would say that the recent 40•c weather Melbourne recieved would have done the trick. I know that it crisped up some of my trees. I know most of this has been mentioned but 1 more time won't hurt If you repotted recently, the tree is pot bound, in an exposed spot, or let to dry out, watered too much, moved from a shady spot to a more exposed spot in the time prior to being burnt or the trees location has become more exposed as summer continues?

ok i actually moved the tree to get it out of the suns ray to a slighlty shader side but the area it is in is still the same wind, but bearing in mind the wind here was pretty harsh those few days of 40 plus and very very drying .. afew of my otehr plants birch and that have dried up leaves but not to this extent etc . yes she does need repotting but i didnt want to stress her.. i got her last year in a pretty pooor state so i wanted to deal with her and bring her back to life from the 8 leaves and for my first maple iwas very happy i did so to 40 odd leaves.. but the case now seems quite tight and compact. i have tried not to let them dry out over the harsh few days we have had
and trimmed off the leaves that were caught with the sun and it is only since then she has gone curly leafed and sad. will post pic tomorro

Some of my trees did not show much sign of leaf burn until a day or 2 after the hot weather, then I noticed leaves we're all crispy on the edges or were completely crispy. Just think of it as a defoliation

Yep that will Make them curl up and die if in full sun.
cut off all the crispy ones and then keep the water up to it

should be OK

Sahara i have had a few in this condition over the years and most have grown back ok. Many trees shed their leaves to save their life in water shortage then reshoot if water is available.
If it was mine I'd cut all those long new shoots to 1 pair of leaves. This will give it a better chance to shoot out in fewer places to save energy.
As Damian alluded to, potbound trees are notoriously hard to keep properly watered. I'd probably soak the pot overnight at least once a week to make sure it gets properly wet as well as your normal watering regime. For trees in small pots a humidity tray can help slow drying out during the day.
Good luck.

Hey Sahara, From the photo this one doesnt look good. What kind is it? Anyway Cut off all the leaves and check if the top branches are flexible. I would cut a bit of branch especially the ones on the photo that look abit slightly more brown than purple and also ones that look like the bark is wrinkling. Check inside the stem rings if theres rotting or dark blotches. If there are, then you have to cut off all the rotting wrinkling branches and poke holes into the soil. Add some root fungicide and hope for the best. If its fertiliser burn then put the whole tree under a tap and let it run for about 5 to 10 minutes to leach the fertiliser out. Then hope for the best. If its none of these, then just wait after cutting all the leaves, it will usually flush new growth. Most japanese maples will, although some fancy rare varieties may weaken.

tu for yur advice 'stem rings? can u explain sorry and when u say cut leaves of completly cut off from stem of just the leaf, i have poked hole inthe soil and the water pretty much runs straight through.. anyone in melbourne around to help lol sry i have heaps of trees and doing reading but hands on help i find is great to.

Sahara, Yep, just cut leaves where the leaf stems are. I mean cut the leaf stems (petiole) in half. The rest of the petiole will drop off eventually. Check to see any darkening branches with wrinkling bark (dark brown or black), If you do, just cut the branch and check the cross-section (where the ring count for age of tree is). If the cross-section is black in the centre or with dark blotches, then its not a good sign. Try and cut all of the branches where you suspect these occur, if not then this dark blotch will spread and the tree will succumb. Before I go on, firstly I would just ask you to check any signs of browning and wrinkling of bark on any of the tree and does it look like its spreading? If not, then just cut the leaves and wait, try and at least have some of the top part of the tree exposed to some sun during the day, buds do need sunlight. Then just wait for the second batch of leaves to come out. Abit like a natural defoliation.

ty for eveyone advice will do this today hopefully once migrianes gone
