Do not pick the flowers/flowers

[Winwin2011]

Signs in the park

1.Do not pick the flowers.
2.Do not pick flowers
3.Do not climb the tress
4. Do not climb tress


Is it correct to leave out 'the' in the above signs?


Thank you.

We use 'the'. We are referring to the trees and flowers in the park, not to trees and flowers in general.
