What's wrong with my satsuki?

[junmilo]

Hi all,

I noticed on of my Satsuki leaf started to curl into the middle and when I touched them it feels dry and when I squeezed it, it is crispy like flaky...when I break the branch, I can still see green.

Is it too late? Dried up? Any tips? Here is a photo.

Thank you

Starting to curl? They been curling for a while!

There is something very wrong, and I would assume problems with watering, but need more info. What kind of soil? History of the tree? Did it get very dry at any point? Is the soil soggy? It may be too late.

I got it about 3 weeks ago. It is still in the original container. There was a heat/warm spell early last week when the temperature reached 40 C. I watered every morning and evening like the other small size Satsuki I had and all of them were fine, except for this guy...i don't see any bugs or anything on/under the leaf. I was waiting for dormancy to kick in to repot them.

To much Sun at 104F perhaps? If in the original substrate it could have dried enough at that point to compact the soil in a way that the water is not getting to the roots properly and just running down the sides of the pot. Take a skewer or similar and starting near the trunk and aerate it a lot - pretty certain that will work good for you introducing water to all the roots again.

Wow 104 in Toronto in September? Regardless, my first thought, and especially if you have other satsuki that are fine, is that it had been mistreated and there were problems before you got it. Three weeks is not very long to do that much damage.

I grow ours in partial/shaded light, they never get more then 2 hours of morning light on the longest day. They also cannot be dried out but caught soon enough with aeration, less light, and water I am pretty certain it will recover. What type of Satsuki is it? The reason I ask is my Tsuki No Shimo is a curled leaf variety and although mine has healthy foliage yours looks similar -

Thank you for sharing. I'm not sure of the variety, however when I got it, none of the leaves were curled they were all flat up and until the five day of scorching temperature. I just took it out of the original contair and the roots were all nice and wet, the soil mix is Kanuma and grit.

Only good clue I have on this one then is to much light and/or a fungal problem. I would give it a lot less light and treat it with Daconil weekly if it were here.

Satsuki growers "normally" know what they are selling - contact them on all of yours for a good ID - it is a good advantage when things go wrong.
For example not all the foliage on the one I showed is curled but is at different stages of growth it is common.

Thank you, I relocated into another area and trimmed off the crispy leaf. Notice a lot of smaller and fresh normal leaf in the middle.

Will monitor it for couple of month to see what happens.

Grimmy,

thank you. Does your leaf feel hard? and when you try to break it, does it come apart very easily into flakes? we don't have Docnil in Canada..there's hardly anything in Canada..Everything is banged.

Sincerely,

J

No, but I was pretty certain early on if you skewer a lot of holes in the soil and water it the center mass of the soil had hardened in the heat. That will intro new water to the dry center root ball.
Less sun, I give them 2 hours eastern max per day, otherwise shaded.
The leaf on any or most should be firm and also flexible. Once starved of water which introduces air during the process that drying is common. Those leafs will never rehydrate but if trimmed off new will appear, roughly 2 weeks depending on the season.
