Hi, I've planted daffodils in loamy ordinary soil with good drainage for years at a depth of 12" which is very deep for many people. I have never had a problem with blooming diminishing in subsequent years and they do not rot or lower in numbers. I have a much later bloom time, which I very much seek since I am not usually outside much in March to enjoy them. I am wondering how many other people plant their daffodils very deeply, as in a foot deep or more. I plant tulips very deeply, too. I can extend the daffodil bloom throughout all of April on daffs that bloom in March, and the tulips tend to perennialize considerably better at that depth. So, I'd like to know has anyone planted daffodils in loamy soil at a depth of 12" or more? Clay soil would probably have adverse effects on the bulbs health and eventually they would peter out and rot. Thanks, Matt.
