I would like to multiply the two rasters (in R) but they do not match exactly. What are my options to be able to multiply the rasters?

You can convert them to the same resolution using resample():
require("raster")
garden_5mplus <- resample(garden_5mplus, veg_g)
There is also a resample() function in raster's successor package terra.
