Fronds and geometry mesh forces - some fronds facing the wrong way

Hi, I’m trying to make some ivy wrap around a tree trunk using fronds and a geometry mesh force. I’m having trouble getting the fronds to all face away from the trunk, it seems like turning the force on causes some of the splines to be rotated. Is there a setting or combination of settings I can use to get the fronds to all face outwards?

I’m using 9.5.2 at work but have the same issue with my indie licence at home with version 10.

Here is the result with the mesh force applied:

…and the view from the inside…

Hello. Do not apply force to the leaves, only to the branch.

Hiya, no forces applied to the leaf fronds, only to the parent spline branches.

When applying force to the table, the branches do not stick.

I’m sorry, I have no idea what you’re trying to say.

Still haven’t solved this! Anyone else got any ideas?
