I purchased a 2-year-old mulberry plant from the nursery. it is about 15 feet in length. When I planted it in the soil, I planted it 2 feet deep, but the actual root part with it was about 1 feet deep. So kind of planted 1 feet extra. I thought it will give it a good grip on the soil.
But now I have read that planting it too deep will kill it. Is it so? What can I do now? I planted it 2 days ago. And my soil is mostly sandy.
