Metry garden questions

Anyone have a document or something that has all things gardening and lawn care maintenance schedules? Like how often to water, when to put down certain chemicals and fertilizers, when to prune different species, etc? I think I’ve seen an LSU Ag calendar in the past that may have included things like this?

Also, anyone have a recommendation on someone who does garden and lawn assessments to see what I might be doing wrong and what I need to change? Most of the companies I’ve reached out to offer landscaping estimates for installs or maintenance, but not really assessments of what you have going on in your yard and what the owner might need to do differently to improve the condition.
