Does one need to give possession of the food to all other others in shituf mevoot? What about eruv techumim or eruv tavshilin? Can a woman join on behalf of her husband without his knowledge?

Can one use an Ashera tree (one used for idol worship) for the post or crossbeam? What happens if the food diminishes and doesn't have the requisite amount - does one need to add food?
