Persimmon crispy leaf tips (forum)

maxzoo starts with ...
Hi,
Just a question about my Fuyu persimmon. It was a lovely tree with lots of new growth and then along came a wallaby and most of that got eaten. It has fought back and has the growth as can be seen in the picture. My question is about the leaves- they are going crispy on the tips/edges and do you think its the sunshine? or is the tree missing some nutrient to make the leaves plump and big? It has been pretty hot in the subtropics and not much rain lately. I am just nervous as I want this tree to prosper!
Thankyou

Saline water can do this also. Do you use bore water or washing machine water?

Hi srt,
Just rainwater here. I am thinking it's the heat and dry which has been excessive here this spring. I hope the fuyu persimmon holds its odd leaves til autumn and then can have a little rest and recover. As a tree it has grown more then the other 3persimmons I have and while they have all seemed to stop growing after their flush, this type still has more leaf buds forming :-) although the other trees do look better leaf wise.

Excess salt and a few nutrients can have that effect as can a K deficiency.I reckon a K glut or general fertliser excess could be the culprit.

Also, your trees still have pretty fresh spring flush growth, unhardened off, so more sensitive to all the above. Also the leaves are cupped. I would guess the conditions were not right to support the full growth flush, ie too hot, wind burn, uneven water.

thankyou for all the suggestions, I am not sure where the salt would be coming from- unless too much seasol can do that? I have been applying seasol weekly to leaves and roots to help nurse it along...oops?
I haven't applied any potassium directly so maybe i can try adding some potash?
fertiliser wise it was planted with a mix of garden soil, old horse manure and some 5 in 1 from searles..
Water wise I have had an earth bag keeping it drip watered since I planted it- maybe too moist?
It is in a semi exposed spot so wind burn and just general hotness are definite culprits and thanks for highlighting the cupped leaves (i didn't know about this symptom and what it can mean til now)

I saw one at the shop today- a fuyu variety and it also looked poorly compared to other varieties..maybe my batch was bad...is that possible?
its not dead yet and I certainly won't give up on it looking fantastic one day.
Thankyou!

I would cut out the foliar sprays, or lower the rate, and apply after heat of the day is over/not in direct sunshine.
Also apply to the roots more frequently at lower rates.
Most seasol products are boosted with extra nutrients, if strong spray mix is drying out on leaves, the EC (=salinity)on the leaf surface increases.

Fertliser in the planting hole is often advised but I am not a fan of it.Direct sun,heat and wind can exaggerate other problems.
