trash

so visual trash annoys some people, like this garden field

they like a much neater field, like this one

the issue is that birds and insects use vision as well

and they will eat all your small plants if they can see them,
if you have trash in your fields then you can save as much of 80% of your seedlings over having things all neat and clean.
if it is harder for you to see all the new tiny plants, then it is also harder to see for everything else,
but screening the seeds in also works if you have a small area.
