How to make a model be attached to a different model's CFrame

hello guys,

i have been working on a Grow A Garden type game, but when testing, i found out that if i save a “plant” from a old plot, and then load into a different plot, it saves the CFrame of the old plot’s Model (meaning it loads all the plants in the old plot), where all the plants are. how could i make it so the plants are all attached to a selected plot’s model, so the plants cannot be loaded in the CFrame of the old plot (aka a different plot)? how i did the old saving is just save the CFrame of the plant in the model, but that didn’t work.
