Creeping Jenny Poorly

[Lewie]

Hi all.
I planted a creeping jenny behind a rock with the intention that it would grow up the rock, over the top of the rock and spread out covering most of the rock with water cascading through it (see pics)
It started well, nice and green, but as it grew the first six to eight inches were green and healthy looking but the rest was bare of leaves and looking very brittle.
I kept it boggy and planted it in aquatic soil.
Any one know what i'm doing wrong?

Can you describe your pond setup?
Size, filtration, fish population, your location/temperatures?
The numerical results of any water tests you've done?
Perhaps provide a picture of your overall pond setup.

@Lewie I know they say it likes moist soil but maybe yours is planted in too moist of soil. Mine is just planted on the high edge of my pond where it dries out quite often but the vines still grow nicely right into the pond and also down the dry side to my pavers. I have to keep it trimmed back when it reaches the pavers or it will take over the whole walkway!

I learned my lesson with creeping jenny.

Creeping jenny is not doing well? Your plant crow is too wet. The crown cannot tolerate water... unlike the roots and the leaves.

The crown cannot tolerate water

Correct - it should be planted so the plant itself is out of the water. It will send runners into the water. As far as growing over the rock - it may be that the rock itself gets too hot, and it's baking the runners.

Mines in my bog doing fine. Just root mass in the water.

I have it in the stream, under water, in the bog, wet crown, along the pond edge, and in dirt. It just grows. Full sun seems to help

Well, thanks for all the replies.
Mitch, i'm in the uk, had a decent ish summer. My pond is a small (480 litre) 'wildlife' fishless. A pump feeds up to the rock 6.5 m away and re enters via a small stream.
Had loads of grief with blanket weed most of the summer.
No filter, read I don't need one with such a small pond?

j-w, take that photo down now, that's not how a creeping jenny should look

It seems it's just me as every one else's jenny is thriving
And in so many different situations,wet, dry, sunny, shady.
Grrrr.
I shall have to do more experimenting.
It all started so well!!

I'm wondering if your soil is turning a bit anoxic - running out of oxygen.
Maybe try planting the roots somewhere there's more water flowing through the soil.

Agree with Lisa, the runners could be getting baked as it grows over the rock. The creeping Jenny by the pond in front of my house gets the runners baked on the rocks during the summer months. However, as soon as it cools off it grows right back up and over the rocks again.

I thought the hot rock may be a thing but even ones that don't touch the rock are affected.
The oxygen thing sounds possible.
Where I want it to grow, getting the roots in flowing water wont work but I will try to provide more oxygene by lessesning the bog effect.
