Trident Maple / too much water?..

Hello,
I'm wondering why my trident's spring leaves look so sad and droopy? I have attached three images - one showing the sad leaves, and another showing leaves from a grafted seedling on the same tree that are much more perky looking, and the third shows both my trident and my arakawa next to it that is receiving the exact same watering regime and seemingly very happy and healthy..

I'm suspicious that I'm overwatering since I have an automatic watering system (I only get to visit them on the weekends), so I've reduced from twice a day to once a day. It's been really windy this year also, so maybe it's that?

The fact that the arakawa next to it is doing so well may help determine the problem - do arakawa's like more water, and trident's prefer less?

Any ideas or suggestions would be appreciated.

Thanks,
Steve

With the size of those pots, and your climate this time of year once a day is too much. If they were planted in all non-organic grit like turface you could water 2-3 times a day and they would be fine, but yours appears to have some organic components that will hold too much water in the root zone.

As long as it's in the 70s or below you should be able to go 2-3 days before watering.

Thanks Joe.

They are planted in a mostly turface mix. I added a top layer of sphagnum since it seemed to be drying out too fast - that stuff really holds the water so I've removed some of it, and cut the watering regime in half.

Do the leaves seem to be indicating overwatering based on your experience?

Thanks again,
Steve

When you say sphagnum do you mean the stringy green moss, or sphagnum peat moss?

Steve,
Why are the other leaves grafted onto your trident? They look like amur leaves to me, and I much prefer your trident. They are very delicate.

I don't know that there's anything at all wrong with the trident leaves you showed. Theres a great deal of variability in leaf and petiole (leaf-stalk) size and color. Yours looks fine and that red petiole is actually pretty desirable. Because it's so thin, the leaves hang vertically. The other leaves you show are much coarser and of course stand out more horizontally.

Where did you get this tree, how long have you had it? Who grafted the other foliage on there and why? Do you have some shots of the whole tree?

Good luck!

Joe,
It is sphagnum peat moss - the fine, non-stringy kind.

Chris,
Here is a link to my photo journal of this tree:
http://www.bonsaix.com/trees/trident.htm

The grafts are to add much needed surface roots. I noticed a little variegation on the seedling leaves as well.

Thanks for the reassurance that the leaf droop isn't something to worry about too much.

I fertilized this week, we'll see if that helps them perk up a little.

Thanks,
Steve

Looks like you got some ganja foliage in the background there.
