Deductions & credits

I am asking again for verification because I had also posted the same question in another website and a (supposed) tax expert told me that 'yes', I could claim / include both my landscaping and my whole house natural gas  emergency generator as part of my 6% home office space deduction. 
And then they doubled-down on that when I asked for verification. 
Again, the situation:  I have a home business office that I can deduct 6% of my associated home expenses.  I made 2 major home improvements in 2020 -- 1 was a major landscape upgrade and another was the purchase and install of a whole house generator that will automatically turn of when I lose power to my home. (I live in Florida and it sometimes happens with hurricanes).

 

Thanks.
