There is nothing more disheartening than having your berries be almost ripe one day, and completely wiped out by birds the very next day. It is amazing how fast birds can pick an entire berry bush clean. The simple solution is to net your berry bushes to keep the birds from getting to your precious berries.
We recently purchased Bird Block Netting netting for our berry bushes and fruit trees. There are many types and brands of netting available, and I am not saying the other brands will not work as well. This is just the brand we purchased due to the price and the size (we are rather cheap).
