What to use to keep crows out of garden? Tried fake owl and tin plates

• Fruit crops can be protected with flexible bird netting. You can find some at a local garden center or hardware store. Four-inch mesh is recommended as it will keep the big crows out, but still allow smaller birds to slip through.
• Place netting securely at the base of a shrub or the trunk of a tree. This keep crows out from the bottom of your trees. Nets can also be used for growing crops.
• Protect seedlings with covers. Corn can be protected by placing a cup or bag over each ear after the silk has turned brown.

• Fishing line or cord can be placed in grid like patterns high above the garden to prevent crows from swooping in from above.

Why do you want to?

Maybe several wind chimes

Mogie's answer is right on, I would use a smaller than 4" bird netting and secure it to the ground to prevent the birds from entering from below the netting.

Bird netting. Crows are smart - and mate for life - respect them.

Some may not like my idea; but, it works. My dad had the same problem with a pecan tree in our yard and asked a local farmer what he could do. He had already tried what you used and it did not help. The farmer told him to either shoot 1 crow or find one already dead and hang it in the tree. crows will not go near a area were another dead crow is. This is a old farmers choice that works.
