Slowly growing

After planting my sunflowers we had quite a few problems. I planted 16 seeds. By day 8 only 5 of them came up... darn squirrels. You could tell where the squirrels had dug up the seeds, even with the fence. By day 10 only three seedlings remained. My husband recommended putting another fence around the two best seedlings, so I took his advice. We put a large fence around the best seedlings and prayed that they would continue to grow.
