Can be many reasons to cause that.
One could be low light causing plants to "stretch" towards any available light.
Which light do you have over what sized tank? (size + dimensions).
Another could be your plant selection. Some mosses do not grow horizontal, rather they grow vertical. A few examples of this are Flame moss and Amblystegium serpens.
Other plants commonly attached to wood that would grow tall are larger anubias, java fern and bolbitus variants.
Smaller variants of anubias, java fern and bolbitus should grow horizontally, across wood. Buce can as well.
I would recommend Christmas moss, java moss, anubias nana "petite" java fern windelov and some smaller Buce species.
Also, any pictures of the plants that are not growing how you want them to?
