Why are my multiple debounces not working?

So I'm making a blooming garden, which the person themselves grows just by stepping on it.

If they step on the soil, the seed will become transparent, and a sprout will bloom in place. If a person steps on the soil again, a flower will bloom in place.

This is my script so far:

debounce = false

script.Parent.Soil.Touched:connect(function()
	
	if not debounce then 
	
	    debounce = true
	
	    for i = 0, 1, 0.1 do
		script.Parent.Seed.Transparency = i
		wait (0.1)
	end
	wait(10)
	debounce = false 

	end


debounce = true

if debounce then 
	 for i = 1, 0, -0.1 do
		script.Parent.Sprout.Transparency = i
		wait (0.1)
	
	end
		wait(5)
	

end
	
end)


 

The problem, the seed "dissolves" once. But the sprout, keeps appearing to flash as a result of it being touched too many times. Hence, I thought a debounce would be a good idea to fix this.

In other words, the debounce worked for the seed but not for the sprout.
